Since the introduction of home blood glucose monitoring (BGM) systems over 40 years ago, diabetes management technology has seen incredible advancements. (14) The drive for growth in these devices stems from the fact that nearly half of the U.S. population has diabetes or prediabetes. Additionally, recent trends have shown increased interest and use among individuals without diabetes who want to use glucose data to help them better understand and improve their metabolic health and see what spikes or causes drops in their sugar. This can be food, stress, or workouts. (7)
“As glucose monitors become more advanced and easier to use, they will provide patients information on their diabetes or a window into their health,” says Dr. Neil Paulvin, a longevity and regenerative medicine doctor.
“Continuous glucose monitors (CGMs) allow patients to determine certain foods or carbs that trigger a sugar spike, if work is too stressful, if they are not preparing for a workout appropriately, or much more.”
Dr. Neil Paulvin, DO., Fortune Recommends Longevity Advisor
Whether you’re looking for a glucose monitor to help you manage your diabetes or inform you of healthy lifestyle changes, there are many variables to consider to ensure it fits your needs. For example, it’s important to remember that CGMs take glucose readings of fluid underneath your skin, not your blood. Fingerstick glucose testing tests your blood for glucose. There is approximately a two-minute delay from your blood glucose to the glucose level in this fluid.
Weeding through the vast array of options can feel overwhelming, so we’ve done the work for you. After conducting extensive research on key parameters, such as cost and insurance coverage, accuracy, ease of use, and integration with other diabetes devices and wellness apps, our team has rounded up the 10 best glucose monitors to support diabetes management and overall wellness.

Best overall glucose monitor: Oxiline Gluco X Pro
Key product features
What you should know
The Oxiline Gluco X Pro is an exceptional blood glucose monitor that delivers accuracy in an easy-to-use design. You can use the device alone or connect it via Bluetooth to the Oxiline smartphone app to store unlimited results and easily track glucose trends.
- We found the monitor offered a simple testing process while delivering quick, accurate results.
- You can buy the Gluco X Pro kit with enough supplies for 50 tests for $59, or you can subscribe to a 1-, 3-, 6-, or 12-month subscription for supply discounts and automatic re-ordering.
- The monitor displays results in a large, bold font on a brightly lit screen, making it easy to read in any environment and any time of day or night.
- Mobile app integration allows you to track your glucose trends based on current and previously stored results, meal information, and how you feel.
- The highly customizable alerts were a standout feature among users to help reduce alert fatigue.
- The Dexcom G7 can transmit results directly to your phone to track your glucose readings seamlessly without needing a separate receiver.
Why we like Oxiline Gluco X Pro as best overall
The Oxiline Gluco X Pro offers an ideal balance of simplicity and advanced features that can make it an optimal choice for any user. Accuracy and speed are two of its strengths, delivering reliable results in under five seconds.
We were instantly drawn to this monitor’s sleek design with a large, illuminated display screen. It’s easy to read your results even when testing at night or in a dark environment. Additionally, the setup process is straightforward. All you need to do is remove it from the box, insert two AA batteries, and turn it on. It’s ready to test without needing to do any configuration or perform control tests. The monitor comes preset to Eastern Standard Time, but we found it easy to adjust it to match a different time zone if needed.
As a vital component of any glucose monitor, accuracy was at the top of our list during our evaluation of the Glucose X Pro. We found the medical-grade sensors incorporated in this glucometer provide consistently reliable results.
The monitor has a large storage capacity of up to 500 results at a time, or you can get unlimited storage by downloading the Oxiline app and connecting your device via Bluetooth. We like that this added cloud storage allows you to track glucose trends long term. Plus, you can add notes to each reading about your meal habits and how you’re feeling. If you’d like to share your results with your provider, you can easily download a copy to send or bring to your next appointment.
We feel this monitor is competitively priced for all it offers. Oxiline presents four subscription plan options that offer discounts and make it easy to set up a recurring order for test strips and lancets to help ensure you don’t run out. You can choose a one-, three-, six-, or 12-month plan. Each comes with a free Glucose X Pro monitor, and you can cancel or pause it at any time.
If you don’t feel ready to commit to a subscription plan, you can opt for a one-time order for $59 full price to get the glucometer and enough supplies for 50 tests. However, we found it was much more cost-effective to go with a subscription. For example, the monthly subscription costs $35, including the glucometer, 100 test strips, and 100 lancets. On the other hand, a one-time order for 100 test strips and 100 lancets, not including the monitor, will cost you $59.
The lancing device included in the glucometer kit offers five levels of skin penetration. Adjusting the depth can help you find which level is ideal for blood sample size while easing the discomfort of the fingerstick. One downside is that you can only use the Gluco X Pro testing strips. Additionally, the glucometer and supplies are only available through Oxiline’s website, so you can’t get it at your local pharmacy or shop around for deals.
Another highlight that caught our attention was the lifetime warranty. Oxiline states that it is confident that its devices are high-quality and made to last. While we couldn’t put the Gluco X Pro to the test long-term, we felt reassured that we would have coverage should something go wrong.
What customers are saying
The Trustpilot ratings aren’t impressive at first sight, with a poor average rating of 2.1 stars. However, we found plenty of 5-star reviews from happy consumers who praised the company for producing accurate devices and providing exceptional customer support.
One Trustpilot reviewer, Joseph Cowan, had only good things to say about Oxiline: “After my doctor advised me to monitor my blood sugar levels more closely, I decided to purchase the Gluco X Pro. Having used other glucometers in the past with mixed results, I was pleasantly surprised by how easy and painless it was to use the Gluco X Pro. It gives me accurate readings every time, which is crucial for managing my condition. Their level of service is exceptional. I highly recommend Gluco X Pro to anyone needing a dependable glucometer.”
Matthew Macadam is among many of the Trustpilot reviewers who experienced a seamless shopping experience, writing, “Oxiline was a great shopping experience for me. They were quick to answer any questions and offered fast delivery!”
Unfortunately, shipping times were a sore spot in most of the one-star reviews we encountered. We also found that not everyone experienced the same customer service support, with some feeling disappointed that the online chat wasn’t with a live person and others stating their emails went unanswered.
Trustpilot reviewer Melissa Masters shares their shipping experience: “I placed my order eight days ago, and I’m still waiting for it to be delivered. The website promises three to four days for delivery. Tracking the package shows it is still in New Jersey. I live in Colorado. I imagine anyone ordering a glucometer would likely need it faster than this. I don’t want to wait two weeks to get test strips every time.”

Best glucose monitor for in-depth information: Nutrisense Continuous Glucose Monitor
Key product features
What you should know
Nutrisense is a robust continuous glucose monitoring program that blends detailed data tracking and trends with personalized nutrition support to help you optimize your metabolic health.
- One-on-one nutritionist support is a strength of this program, but support only lasts one month unless you want to pay an additional fee for continued access to your nutritionist.
- Subscription plans range from $225 to $399 per month based on how long you’re willing to commit to the program. Beware of automatic renewals at the end of your initial subscription time frame.
- This program may be more helpful for individuals who thrive on human connection and want to stay motivated and accountable to their goals.
Why we like Nutrisense Continuous Glucose Monitor as best for in-depth information
With the Nutrisense Continuous Glucose Monitor program, you don’t have to navigate and interpret your glucose data alone. Its detailed reports and live expert guidance help you understand what it all means for you and your health.
We took the short questionnaire you fill out during signup and liked that it helps personalize your program based on your goals, health history, and preferred coaching style. Then, you can choose between a three-, six-, or 12-month plan.
Once you’re signed up, a Nutrisense-partnered physician will provide a prescription for you to receive a Freestyle Libre 3 continuous glucose monitor. Throughout the program, you’ll use the CGM to track glucose data in relation to your lifestyle habits. “You will need to scan the CGM with the device the Nutrisense app is on to obtain your glucose level,” adds Dr. Dhargalkar. “Once you do this, the app provides a color-coded response to give your measurements, with green signifying ‘good’ and red signifying ‘needs improvement.’”
Additionally, all plans include one-on-one support with a credentialed nutritionist. We found it easy to communicate with the nutrition coach through the in-app chat feature or via email.
If you prefer face-to-face interactions, you can add on video calls with your nutritionist, but it comes at an additional cost. However, when we evaluated this feature, we learned that insurance may cover these sessions. In fact, Nutrisense states that 95% of individuals pay $0 out-of-pocket.
We appreciate that Nutrisense hasn’t completely lost the human touch. Technology is an excellent tool, but research shows that receiving support from a real, live person leads to more weight loss than programs using technology alone. (4) “Personal interaction can help improve action and retention,” adds Dr. Paulvin. “There is more accountability. Plus, the real person can discuss patient history to combine with their numbers.”
However, after our evaluation, we were disappointed to learn that the one-on-one support is only included for one month. After that, you decide to say goodbye to your nutritionist or pay more for an upgrade or add-on.
You’ll continue to have access to the Nutrisense app and continuous glucose monitoring throughout the program. Like other programs, you can log your meals and receive a corresponding score and macronutrient breakdown. Additionally, the self-guided learning program can be a helpful way to learn more about glucose, nutrition, metabolic health, and other health topics.
If you’re data-driven, you may appreciate the level of detail Nutrisense includes when it compiles your CGM data into detailed graphs and charts to help you recognize trends and patterns in your glucose levels.

What customers are saying
The Trustpilot reviews of Nutrisense shared common themes regarding the helpfulness of the nutritionist support. Users felt the program’s benefits outweighed the high cost.
Verified user Joy W. wrote, “The Nutrisense team is responsive and helpful. My nutritionist worked closely with me to adjust my eating to keep my blood sugar in check. The app is informative and provides historical data and trends. I’m glad I chose this program to optimize my health.”
Pamela J. is a verified customer who admitted to being apprehensive about the total price of the program but said they already knew it was worth it after one month. They wrote, “Being a total novice in the world of CGM, this app and the support staff are excellent at helping make sense of it all. There are many educational tools, and my nutritionist Katie had so much good advice and suggestions.”
However, budget remains a limiting factor for some users, no matter how much they enjoy the program.
For example, verified Trustpilot customer Mitch started their review with praise for the real-time glucose data and nutrition insight but took one star off their review, saying, “I gave it four stars, though, because of the cost. I understand the technology-related costs, but unfortunately, it’s just something I can’t stay with long term.”

Most accurate glucose monitor: Dexcom G7
Key product features
What you should know
The Dexcom G7 continuous glucose monitor (CGM) is renowned for its small design and accurate glucose readings. This CGM is easy to use and painless to apply. It’s compatible with the Omnipod and Tandem t:slim X2 insulin pumps and has a fully redesigned app compatible with smart devices. It’s also compatible with other health-tracking apps.
- Our research aligned with user reviews that praised the device’s accurate glucose readings. However, some users noted intermittent connectivity issues between the monitor and the app, which resulted in occasional lost data points.
- The Dexcom G7 is accepted by most insurance and Medicare for eligible individuals, but the $377 monthly cost can be pricey if you’re paying out-of-pocket.
- The CGM is designed to help manage diabetes in individuals diagnosed with type 1, type 2, and even gestational diabetes.
- The highly customizable alerts were a standout feature among users to help reduce alert fatigue.
- The Dexcom G7 can transmit results directly to your phone to track your glucose readings seamlessly without needing a separate receiver.
Why we like Dexcom G7 as most accurate
Dexcom is a global leader with over 20 years of experience in the continuous glucose monitoring market. Already ranking as the most accurate CGM with the G6 model, the brand continues to impress after rolling out the newest model, the Dexcom G7.
Our research into the Dexcom G7 echoed user experience, who praised the device’s small size, ease of use, compatibility, and accuracy as exceptional highlights.
Size matters when it comes to wearable devices, and we appreciate that Dexcom slimmed down the G7, making it 60% smaller than the G6. Moreover, users have raved about the painless sensor application in the G7’s 90-degree angle insertion–a change from the traditional 45-degree angle.
You can wear each sensor for up to 10 days before replacing it. While this is a slightly shorter wear time than some competitors, the Dexcom G7 helps compensate for it with a 12-hour grace period that allows you to replace the sensor when it works best for you without losing data. However, consumers should consider that this feature leads to higher costs and more frequent changes, and other brands are available for a third of the price.
Another key feature of continuous glucose monitors is sending alerts for high and low-glycemic events for improved diabetes management. However, studies have shown that when alerts occur too frequently, it can lead to annoyance, dismissal of alerts, and even discontinuation of CGM use. (11) We noticed that the Dexcom G7 provides a high level of customization for alerts, including the ability to delay the first alert, snooze alerts, and even turn alerts on vibrate or silent.
Like previous Dexcom CGM models, the G7 boasts integration with certain insulin pumps and pens. This unique characteristic of the Dexcom CGM system can help you reduce time spent on insulin management through automated insulin adjustments. (15)
One limitation of the Dexcom G7 is its shorter transmitter range of just 20 feet. Additionally, some users have experienced connection issues between the sensor and the app, even when their phone is nearby. However, users applaud Dexcom’s customer support team for being incredibly helpful in troubleshooting and sensor replacement.
Without insurance, the cost of the Dexcom G7 can become an issue at a pricey $377 per month. Fortunately, the CGM is widely covered by private and commercial insurance for eligible individuals. If you’re a Medicare patient on insulin, you may also qualify for the device at a lower cost.
Dexcom has upped the game with its newest G7 continuous glucose monitor, which offers continued accuracy, even more convenience, and customization to help reduce the burden of managing diabetes.
What customers are saying
Customers boast about their experience using the Dexcom G7, noting its simplicity and accuracy. When rare issues arise, reviewers unite in their praise for Dexcom’s helpful customer support service.
Trustpilot reviewer “JS” had only positive things to say in their 5-star review, saying, “The G7 is incredible— it’s accurate, reliable, and easy to use. I went through some of the reviews earlier and saw some negative ones. I’m not sure where these are coming from. Nothing but a great experience from my end. Highly recommended.”
Another Trustpilot reviewer, Randy B., emphasized how important customer service is and how easy they find it is to get support from Dexcom’s team. “This company’s customer service is first class. Issues with the device, though rare, do happen from time to time. Whenever these issues occur, I call or live chat with Dexcom, and there is zero hassle. They ask a few questions for their records and ship replacements free of charge for whatever has failed.”
In a YouTube review from the user “andricheli,” the connection issues came to light, but they noted it did not greatly impact their overall experience. “Overall, I have loved the Dexcom G7. I mostly love that it’s an all-in-one deal. I travel some, and I always hated remembering to take an extra transmitter (which I may or may not have had depending on where I was with the current one). I do have some connection issues, but that’s mostly mitigated by staying close to my iPhone.”

Best continuous glucose monitor: Freestyle Libre 3
Key product features
What you should know
The Freestyle Libre 3 is a user-friendly continuous glucose monitor that achieves accurate results at a fraction of the cost of other CGMs. The accompanying smartphone app allows you to customize your experience and see real-time data at your fingertips.
- In our research, we found that users appreciate how small and thin the Freestyle Libre 3 is in addition to the longer sensor wear time before replacement.
- At $170 out-of-pocket per month, the Libre 3 is less than half the price of some competitors. Additionally, it is widely accepted by insurance, including Medicare, Veterans coverage, and TRICARE.
- The Freestyle Libre 3 requires a prescription and is cleared for use in individuals diagnosed with type 1, type 2, and gestational diabetes.
- Users may experience issues with the sensors falling off before reaching the 14-day mark, leading to more frequent sensor replacements.
Why we like Freestyle Libre 3 as best continuous glucose monitor
The Freestyle Libre 3 delivers on usability and reliability and comes at a much more affordable out-of-pocket price than other top competitors. The lower cost doesn’t mean lower quality, as our evaluation shows the Libre 3 is one of the most accurate continuous glucose monitors.
The Freestyle Libre 3 provides real-time results and detailed glucose reports with automatic glucose readings every minute. We love that users can sync their data to a smartphone app or choose a separate receiver. Another benefit of the Libre 3 is the longer transmitter range, allowing you more freedom to move about without worrying about connection issues.
The Libre 3 takes the cake when it comes to size. At just 2.9 mm x 21 mm, about the size of two pennies stacked together, our research indicates the Freestyle Libre 3 is one of the smallest and thinnest continuous glucose monitors available.
While the integrated app allows some customization of high and low glucose alerts, users dislike the inability to adjust the volume of critical alerts to be less disruptive. However, our evaluation revealed that the Freestyle Libre 3 app does allow you to toggle off the “Override Do Not Disturb” setting on phones, which would silence alert delivery when your phone is on silent or Do Not Disturb.
Frequent sensor changes can be cumbersome and costly for CGM users, so we were impressed by the longer 14-day lifespan of Libre 3 sensors. Unfortunately, some users complain about sensors coming off early, especially when exposed to sweat or water. Even though customer support is excellent at delivering free replacements, you may be left with glucose monitoring gaps while waiting for the new sensors to be delivered.
“This can be dangerous for diabetics with poor control who rely on their monitor for this information,” notes Dr. Paulvin. “This can also affect new diabetics or those trying a new dose of insulin and are forced to use finger sticks, which can be painful.”
The Freestyle Libre 3 excels as an accurate continuous glucose monitoring system with a barely-there sensor feel. You can see detailed reports and receive high and low glucose alerts to help you adjust for better glucose control.
What customers are saying
While some long for more alert customization, Freestyle Libre 3 customers like the device’s frequent, reliable glucose readings that help ease the burden of diabetes management.
Kenneth, a verified owner through Diabetic Outlet, was initially apprehensive about the sensor application but was pleasantly surprised with the Libre 3 experience. “I was initially nervous about how to apply the sensor, if it would actually stay on for two weeks, and how painful it would be to apply and remove. Application is painless. I’m only on my third one now, but I’ve had no issues so far. It is amazing to know your glucose level at the push of a button (I use the reader, not the app).”
In an App Store review, verified user “GrantEatonDesign” highlighted overall reduced stress even though he desires more customization in the alerts settings. “The critical alarm needs to be customizable. It is an ear-piercing alarm that you cannot adjust the volume of. Please allow for different volumes and vibration alerts, too. I understand it’s a liability if the alarm isn’t heard, but the fact that there’s no way to lower the volume makes me uncomfortable using it at work/in class. I can’t have this beeping when I’m attending a lecture or taking an exam. This must be changed for diabetics to make this part of their daily lives. This is my only critique as of 14 days of use. It is an amazing tool that relieves stress immensely.”

Best glucose monitor subscription plan: Signos CGM
Key product features
What you should know
Signos is a subscription service that partners with Dexcom to deliver a wellness program with real-time glucose monitoring to help you better understand your metabolic health and reach your wellness goals.
- Signos is not intended to treat diabetes. Rather it’s meant for individuals who want to use real-time glucose tracking to help them reach their weight loss and wellness goals.
- The program’s cost can vary from $143 to $449 per month, depending on the commitment you make when you sign up.
- You can connect Apple Health or Google Fit to automatically track habits in one app.
Why we like Signos CGM as best subscription plan
Signos is a subscription wellness service that pairs a CGM with habit tracking and a personalized health curriculum.
Through the program, you’ll receive a Dexcom G7 continuous glucose monitor. Because a prescription is required for CGMs, you will need a physician consultation to participate. We like that Signos partners with an independent physician as part of the subscription cost, so you don’t need to make a special trip to your doctor.
One more caveat to consider is that you can only receive the CGM if you agree to participate in Signos’ research study, which aims to learn more about the role CGMs can play in weight loss. Dr. Paulvin adds, “CGMs help with weight loss by controlling sugars, which helps regulate insulin. In theory, avoiding food that causes sugar spikes continually may also help weight loss. Lastly, elevated blood sugars affect insulin, testosterone, and estrogen in females, and abnormal cortisol can cause weight gain. You can prevent some of that by monitoring blood sugar and sugar spikes.”
Furthermore, the program only works with the provided Dexcom G7 glucose monitor, so you can’t bring your own if you already have a device or prefer a different glucose monitor.
The program aims to help you better understand how your body responds to what you eat, how you sleep, how stressed you’re feeling, and how hydrated you are. You can see how your activities impact your glucose levels by wearing the continuous glucose monitor while tracking your daily habits.
The idea is that you’ll have insight into what may be causing periods of low energy, and how you can maintain more stable levels.
Additionally, you’ll have access to in-app nutritionist support and AI-powered weight loss insight. We like that the personalized health lessons and activities provide helpful nudges toward behavior modification to help you stay on track with your goals.
If you want to connect with others with similar health goals, you can interact through Signos’ Community board. We found this feature beneficial, considering social support is shown to play a significant role in facilitating successful outcomes in health-behavior change programs. (8)
Signos offers three subscription plan options based on your plan to stay in the program. As you can see in the prices listed below, the longer you commit to the plan at sign-up, the cheaper the monthly cost.
- $449 per month for one month
- $183 per month for three months
- $143 per month for six months
The program is heavily focused on weight loss, so if that’s not your intention, you may want to consider a different option for glucose monitoring.
What customers are saying
We found that Apple App Store users are impressed with the app and the program, earning 4.6 stars overall, while Google Play reviews didn’t match that high level of positivity at 3.0 stars. However, the poor reviews correspond more to app bugs and poor customer service than to the subscription program itself.
Verified Apple App Store customer Anthony B. shared why they feel the program’s high cost is justified, writing, “This is worth every dollar. It really allows you to see how your body responds to different foods and activities. This understanding has allowed me to adjust my behaviors and diet to significantly impact my health. It has also allowed me to continue to eat many foods I love, but I now know which ones to have in moderation or how much exercise to do. If I do eat something, I should moderate it. With one and a half months of use, I have already lost 15 pounds.”
“I love this app. It has been a great tool for controlling my weight and health.”
RavesTTT, Verified Customer
While many app users find meal logging helpful, some complain that it can feel cumbersome and inferior to other popular meal-tracking apps.
“Nurse ucla” is a verified user who wrote in a 4-star Apple App Store review, “Almost every food is unscannable, yet they have a barcode scanning feature. Most foods cannot be found in the app. The way you input portion size is confusing and poorly designed.”

Best glucose monitor for actionable insight: Levels Health
Key product features
What you should know
The Levels Health app allows you to track habits in multiple areas of wellness, including nutrition, exercise, sleep, and stress. Then, it uses real-time glucose monitoring to help you understand how your habits impact your health.
- As a board-certified health coach, I appreciate that Levels Health emphasizes that each body responds differently to foods eaten, and they don’t deliver healthy eating recommendations as a one-size-fits-all diet plan.
- The participation cost varies from $40 per month for the subscription-only plan up to $398 per month for app access and monthly continuous glucose monitoring supplies.
- Connecting the app to Apple Health or Google Fit for automatic exercise and sleep data syncing can help take some of the manual work out of habit logging.
- You have the option to add on lab testing for other key health markers, and the results are uploaded to the app with helpful tips for making health improvements.
Why we like Levels Health as best for actionable insight
Research shows glucose monitoring helps create personalized nutrition goals based on ideal nutrient composition and meal timing. (9) Levels Health uses glucose data and meal log trends to provide customized nutrition insight to help you make healthy choices.
“In addition, this app allows you to complement your glucose data with other pertinent lab work,” begins Dr. Dhargalkar, emergency medicine physician. “How does this work? You complete your blood work at a local LabCorp site, and the results are pushed to your personalized app. Labs measured will help you evaluate cardiovascular health, insulin resistance, and overall metabolic health to help with Levels Health’s overall goal of showing how food impacts your health.”
To get started, you’ll answer a brief questionnaire that will help pair you with the subscription plan that best fits your needs.
Based on our evaluation, one factor differentiating this program from other subscription services is that you can bring your own continuous glucose monitor if you already have one or prefer a specific brand. If you want a monitor through Levels Health, you can choose between two of the top CGMs on our list—the Dexcom G7 or the Freestyle Libre 3.
It’s important to note that if you bring your own continuous glucose monitor or opt for the Freestyle Libre 3, you’ll need a prescription. However, if you agree to participate in the research study, Levels Health can provide the Dexcom G7 without a prescription.
When evaluating Levels Health, we found it helpful that the program encourages you to consider how all wellness areas impact your metabolic health by prompting you to log meals, track exercise, and record sleep. You can import this data from outside apps such as Apple Health and Google Fit. However, we noticed an overall heavier emphasis on nutrition throughout the app and in the feedback.
For each meal you log, Levels Health provides a score based on how your glucose levels responded to what you ate and how active you were. We like that scores are followed by action-based suggestions for healthy food swaps, recipe recommendations, and other helpful tips. In addition, habit loops and streak tracking help you stay accountable for the goals you set for yourself.
Of course, behavior change and health improvements take time, and the high monthly cost of the subscription plan with CGM supplies can limit one’s ability to stay in the program long enough to achieve one’s goals.
Another downside to Levels Health is that you receive support solely through app-generated content and recommendations. If you prefer to work with a real, live coach or other health professional on your wellness journey, you won’t find that in this program.
Overall, we like Levels Health for the data-driven feedback that helps you take actionable steps toward improving your health, making it one of the best glucose monitors and among the 25 top recommended products for your health and wellness.
What customers are saying
Levels Health has over 3,000 reviews in the Apple App Store, and most users find the program easy to follow and helpful for making behavioral changes that lead to health improvements.
Verified Apple App Store customer “LynnzLuLu89” described how well the personalized approach worked for them. “This app has transformed my relationship with food, exercise, sleep, and stress management. In real time, I can watch how these factors impact my metabolic health. Each individual responds differently, and Levels highlights my own unique response in these areas.”
Apple App Store user Mona Sharma is a nutritionist who wanted to try the app to recommend it to her clients. She was surprised by how much she learned and the positive changes she made.
Mona says, “After months of trial, I was able to fine-tune my already healthy diet to boost my energy, mood, sleep, hormones, and even some weight loss. Foods I thought were good for me were actually messing with my glucose levels! There is no perfect diet, so having a science-driven app like this is a resource to determine what foods and when to eat is right for your unique constitution.”
Negative reviews center mostly around app issues for Android users after a recent update release.
For example, verified customer Jase F. wrote, “They’ve changed the interface on this app since the last time I used it a year ago. Entering what I eat is a little more difficult, and there are times when I enter foods, and it doesn’t seem to save them correctly. It makes it pretty bothersome.”

Best budget glucose monitor: Ascensia CONTOUR NEXT EZ Blood Glucose Monitoring System
Key product features
What you should know
You can’t beat the price of the CONTOUR NEXT EZ Blood Glucose Monitoring System. This option doesn’t have as many bells and whistles as some other monitors, but the monitor is easy to read, and the results are reliable.
- We found this monitor to be a strong competitor in the blood glucose monitor (BGM) category with its low price point without sacrificing accuracy.
- This monitor is best for those wanting an inexpensive option for blood glucose testing with its budget-friendly price of only $18.99.
- The second-chance sampling gives you 20 seconds to add more blood to the strip to help reduce the number of wasted test strips.
Why we like Ascensia CONTOUR NEXT EZ Blood Glucose Monitoring System as best budget
Cost is a significant barrier for many individuals regarding glucose monitoring. (13) We appreciate that the Ascensia CONTOUR NEXT EZ blood glucose monitoring system is helping break through that barrier with its low cost of only $18.99.
Of course, with blood glucose monitoring, there are recurring costs in the test strips and lancets. Based on our research, we found the price of the test strips comparable with other brands. A box of 50 CONTOUR NEXT test strips is $26.58 on Amazon.
The monitor and testing supplies may be covered by insurance or qualify for HSA/FSA reimbursement for eligible individuals.
You don’t have to stay on brand for the lancets you buy—you can choose which ones work best for you. There’s a lot of variability in cost based on your preferences for needle size, lancing depth, technique, and price, but you can get a box of 100 basic lancets for around $10.
The blood sample size needed for the CONTOUR NEXT EZ is 0.6 microliters. While some other monitors can produce results with slightly smaller sample sizes, we found this monitor’s sample size is average overall.
CONTOUR NEXT EZ helps reduce the cost of blood glucose testing further through its second-chance sampling. Wasting test strips is frustrating, so having the extra 20 seconds to apply more blood to the strip if your first sample wasn’t enough is helpful.
The CONTOUR NEXT EZ monitor strips are already calibrated and ready to use, meaning you don’t need to manually enter a code each time you start a new box of test strips. This is significant because it can make testing easier and leaves less room for error.
We found the monitor screen user-friendly with easy-to-read results. The monitor also provides 7-, 14-, and 30-day averages of your blood glucose levels. Additionally, you can set personalized high and low target ranges. “Every person’s ideal blood sugar range is different and is based on various factors. These factors include diet, exercise, and genetics. Your body’s response to these factors determines your ideal blood sugar range.” adds Dr. Dhargalkar.
The CONTOUR NEXT EZ lacks app compatibility, so you’re limited to the monitor screen for glucose summaries unless you manually enter your readings into a separate app.
What customers are saying
Earning 4.3 stars on Amazon with nearly 1,600 reviews, customers say the CONTOUR NEXT EZ provides them with accurate results at an affordable price.
Verified purchaser Miwako was most impressed by this option’s bang-for-your-buck, with all the supplies included in the budget price. “It came with 10 strips, a lancet holder, a lancet, and a test solution. This is a great deal.”
“I have used this brand for several years. It’s rated as very accurate. It’s very affordable, and the strips aren’t too bad in price,” wrote verified customer Lori Ashway.
Verified purchaser “Leo9” was impressed by the glucometer overall but noted its larger size could make it more cumbersome to carry. “The large size is surprising to us given technological advances. He can use it but can barely close the zipper around its pouch.”

Best glucose monitor for new users: TRUE METRIX AIR Meter Starter Kit
Key product features
What you should know
The TRUE METRIX AIR Meter Starter Kit comes with the meter and all the necessary testing supplies to start checking your blood glucose levels.
- We applaud the starter kit for taking some of the stress and confusion out of glucose monitoring by giving users a one-stop shopping experience and an easy-to-use device.
- Although the price tag may appear higher than some others on our list, it’s very affordable when you consider everything you’re getting for the cost.
- If you can connect the Bluetooth app, you can go beyond recording your glucose results and gain insight into how your lifestyle impacts your blood sugar levels.
Why we like TRUE METRIX AIR Meter Starter Kit as best for new users
If you’re new to blood glucose testing, getting all the necessary supplies and learning how to test can feel overwhelming. In a study aiming to better understand the barriers to glucose testing in diabetic patients, 72.67% of patients reported challenges due to a lack of knowledge and not knowing how to use the glucometer. (13)
When evaluating this kit, we found that it makes getting started simpler and more efficient. You don’t need to search for all of the separate supplies and wonder if you’re getting the right ones. Everything comes together in one box.
The kit includes 100 test strips, 100 lancets, the lancing device, the control solution, a log book, and a carrying case. Some user reviews noted the lancing device is made of low-quality materials, so they’ve had to purchase a new one separately.
Users commend the glucometer for being effortless to set up and easy to use. We found the user instructions simple, and the short tutorial videos are an added bonus.
When ordering more test strips, you can easily find them online or in a pharmacy for about $31 for a 100-pack. The control tests are easy to run with new test strips, and there’s no coding required, both excellent features for new users.
The meter’s large digital display makes it easy to read your results. You can add multiple testing reminders to help you stay on track with your testing goals.
Additionally, you can choose to connect the TRUE METRIX AIR meter via Bluetooth to the TRUE METRIX connected app. The app lets you send your results wirelessly and tag events like meals, exercise, medications, and illness. As a health coach, I especially appreciated this feature to help users understand the connection between lifestyle factors and their results.
The app also lets you keep your support system in the loop by sharing your results with your provider, family, and friends. Unfortunately, multiple users stated they have issues connecting the meter to the app, so not everyone has been able to take advantage of these helpful features.
What customers are saying
We found many positive reviews on Amazon about the glucose meter’s small size and accuracy.
“Compact size. Easy to use. Fast results. Can’t really ask for more. I use the Glooko app to track sugar. It works way better than the native app.”
Richard, Verified Purchaser Richard
Verified buyer “Jumpers” shared, “This is very user-friendly and accurate. I like that it allows you to record if you just ate, took your medicine, etc. My doctor was impressed with it and the accuracy.”
However, some users noted the ease of use was limited to the device itself, while the Bluetooth connectivity for syncing data was troublesome.
“This machine is easy to use, and the lancing device itself is less painful than others,” says verified customer Andrea. “However, I have gone through two machines trying to get the Bluetooth capability to sync and work…it doesn’t. So, it’s fine if you’re okay doing manual entries (which is no big deal). If that’s something that you can’t live without, I would recommend another device. Overall, easy to use, accurate, and fast.”

Easiest finger stick glucose monitor: Accu-chek Guide Glucose Monitor
Key product features
What you should know
The Accu-chek Guide Monitor Kit is a low-cost option that helps users overcome many obstacles that make blood glucose monitoring challenging.
- The Accu-chek Guide stood out during our evaluation for its easy setup, quick testing, and highly rated connected app, which allows you to manage your data in one place.
- The $29.99 only includes the monitor, so you’ll need to place a separate order for the lancing device, lancets, and test strips before you’re ready to begin testing.
- You can easily connect your meter to the mySugr smartphone app for automatic result syncing, shareable glucose reports, and lifestyle tracking.
Why we like Accu-chek Guide Glucose Monitor as easiest finger stick
Accu-chek is a well-known diabetic testing brand, and the user experience seems to be the top priority for this monitor to make blood sugar monitoring quick and simple.
Learning to use the Accu-chek Guide is straightforward and doesn’t require a big time commitment. The instructions are clear and easy to follow, with detailed photos and simple directions.
While the glucose meter itself is small, the display is large, and the LCD backlighting displays the results in big, bold font in less than four seconds. Below the result, you can add a comment to help track how you’re feeling and how lifestyle factors may influence your results.
Pain is a common reason individuals choose not to practice self-monitoring of blood glucose, and the Softclix lancing device, which you can buy separately or purchase as a kit at Walmart, is designed to help reduce pain during the fingerstick. (13) The 11 lancet depth settings help ensure you get the right amount of blood the first time.
The Accu-chek Guide has a feature we didn’t find in any of the other monitors we evaluated. The testing strip port has a light that automatically illuminates when you insert the strip, so it’s easier to test at night or in low-lit locations. In addition, the test strips leave less room for error during blood collection, with a large collection area that allows you to add blood anywhere along the edge of the strip.
Another hot topic among positive reviewers is the accompanying mySugr app. While a connected app isn’t unique to the Accu-chek Guide, we found that users were unified in their praise for how user-friendly this app interface is. Your blood sugar results are automatically imported. You can connect Apple Health or Google Fit, and the app can help calculate insulin dosing to help you get back in range.
What customers are saying
The Accu-chek Guide is a popular choice on Amazon, earning high ratings among customers who find the meter and connected app simple to use.
“This glucose meter is just perfect! It is very small and easy to travel with. Despite its size, the display is well-illuminated and easy to read. I like how it connects to my phone via Bluetooth and transmits the results of my blood sugar readings to my phone in real time. The companion app allows me to trend my blood sugar levels over time, and reports can be printed off easily for my physician to review.”
Kenneth, Verified Customer
“I like this product because it is easy to use. If you have a smartphone, ACCU-CHEK has an app you use with this glucometer to keep track of your blood sugar. It also has a helpful chart to show you if your glucose is in a good range,” says verified purchaser Diane P.

How we test glucose monitors
Accurate and reliable blood glucose monitoring is crucial not only for individuals managing diabetes but also for those monitoring their blood sugar for other health reasons, such as diet management or other medical conditions. Glucose monitors provide essential insights into one’s health, aiding in effective management and preventative care. “There is a real role for glucose monitoring in people without diabetes. We all produce insulin to help break down sugar accumulating in our bodies and bloodstream. Glucose monitoring helps us understand when and how we do this, our resultant glucose levels, and the effects of sleep, exercise, and diet on all of this.” says Dr. Aneesha Dhargalkar.

What to look for in the best glucose monitors
When choosing a glucose monitor, there are multiple factors to consider to determine which is best for you. Here are some key aspects you should consider as you browse your options.
Consider your reason for use
Are you a diabetic who needs long-term, daily testing to help manage your condition and prevent further complications? Or is your intention to pair glucose data with helpful feedback to help you understand more about your metabolic health and how you can make healthy changes to reach your goals?
Set your budget
The price range for glucose monitors varies greatly depending on the type of device. Determining what you can afford before starting your search can help narrow your choices.
Blood glucose monitors are typically significantly cheaper than continuous glucose monitors, but remember that any monitor you choose will come with recurring costs for replenishing supplies.
Check with your insurance
When considering your budget, it can be helpful to review your insurance benefits to see if glucose monitoring supplies may be covered. For diabetic patients, testing supplies are often covered by most insurance plans, but it’s always best to verify your coverage. Additionally, your insurance may limit you to specific devices or price points.
We found that the monthly subscription plans are generally not accepted as a covered cost by insurance at this time. However, you may have luck reducing costs if services or devices can be reimbursed through your HSA/FSA.
Ease of use
As a general rule of thumb, the easier something is to do, the more likely you are to continue to do it. What constitutes easy can be a personal preference based on how often you need to test and how comfortable you are with technology.
For some, a basic fingerstick model may be the simplest solution. Others may prefer monitors that offer more detailed insight, automatic data syncing, or the set-it-and-forget-it-for-a-bit benefit of continuous glucose monitors.
FAQs
What blood glucose monitor is most accurate?
The FDA closely regulates glucose monitors to ensure they meet specific accuracy standards. To receive FDA approval, BGMs must be accurate within 15-20% above or below the actual reading. (2) For CGMs, the FDA requires 95% of measurements be within 15% above or below the corresponding blood glucose value for glucose levels greater than 100 mg/dl. For glucose levels less than 100 mg/dl, 95% of CGM values within 15 mg/dl (higher or lower) of blood glucose measurements. (5)
We rated the Dexcom G6 as the most accurate glucose monitor for its proven results. It falls well within the FDA’s accuracy requirements with a MARD (Mean Absolute Relative Difference) of about 9%. The smaller the MARD number, the closer the CGM readings are to the reference glucose value. (1) The Dexcom G6 was the most accurate device compared to over 15 other devices over time.
Is there a device to check blood sugar without pricking your finger?
Continuous glucose monitors are popular among individuals who want to monitor glucose trends without a finger prick. Typically attached to the back of the arm or abdomen, these monitors provide real-time glucose data without the multiple time-per-day pain.
Are blood glucose monitors worth it?
Glucose monitors are a critical tool for helping individuals with diabetes manage their condition and reduce their risk of complications, such as cardiovascular disease, stroke, and kidney disease. If you’re diabetic, you may also find that continuous glucose monitors can help ease some of the cognitive burden that comes with managing your health.
The value of glucose monitors in healthy adults is a newer concept that needs further study. However, early research indicates continuous glucose monitor use has the potential to yield positive health benefits. (8)
“The value of continuous glucose and blood glucose monitors cannot be overestimated for individuals with diabetes. Having a regular, consistent blood glucose measurement can help patients make appropriate and safe choices regarding diet, exercise, and sleep, in turn preventing serious medical complications such as dizziness, falls, heart disease, seizures, and even death,” notes Dr. Dhargalkar.
Do you need a prescription for a glucose monitor?
While a standard fingerstick blood glucose monitor can be purchased over the counter (OTC), continuous glucose monitors currently require a prescription. However, that is about to change.
The FDA recently gave Dexcom the go-ahead to market the first-ever OTC continuous glucose monitor. (12) The Dexcom Stelo Glucose Biosensor is expected to be available to adults 18 years and older sometime in the summer of 2024.
What is a normal blood sugar range?
Blood sugar levels are typically tested after fasting for at least eight hours. In healthy adults, the normal fasting blood sugar range is from 70 mg/dL to 99 mg/dL. (3)
For individuals diagnosed with diabetes, it’s best to work with your doctor to set personalized blood sugar target ranges, as they will differ for each patient due to various factors. However, typical diabetic target ranges are between 80 mg/dL to 130 mg/dL fasting and less than 180 mg/dL two hours after the start of a meal. (10) “It is really so variable what an appropriate range would be. For example, children vs. adolescents vs. adults have different ranges, which also varies for Type 1 vs. Type 2 diabetics,” warns Dr. Dhargalkar.
