9 Best Smartwatches with Blood Sugar Monitor: (2024 Guide & Reviews)

Last Updated on January 15, 2024 by Luis Cooper

Individuals with diabetes can benefit greatly from using smartwatches to maintain a good lifestyle.

You can use these tools to control your eating plan, heart rate, caloric intake, or even oxygen levels.

Knowing these strategies can help diabetic individuals control their blood sugar levels.

Dexcom analyses the patient’s blood glucose level and sends the information to their watches or even smartphones. 

People with diabetes can benefit greatly from smartwatches, however, there are a lot of options in the market to select from.

Because of this, determining which smartwatches are best for treating diabetes might be challenging.

The top smartwatches for diabetes are listed below to help you decide.

We’ve conducted an extensive study to shorten our list.

Which are the Best Smartwatches with Blood Sugar Monitor?

Here are my recommended top 9 Best Smartwatches with Blood Sugar Monitors:-

1. HUAWEI Watch 4 Pro: (Best GPS Smartwatch to Monitor Glucose Levels)


One of my friends is a diabetic patient who needs to check his glucose levels every week.

Getting checked by the test is quite expensive and painful.

I suggested that he get a smartwatch and monitor his glucose level independently.

I heard a lot of hype about the Huawei Watch 4 pro, so I recommended he get this device.

This watch helped him immensely by providing a health profile for the day.


Durable Construction: 

The watch 4 pro casing is made of titanium, and the display is protected by sapphire glass.

The brand installs a rotatable and pressable crown on the side as the button holds a sensor.

A speaker is installed with two openings for microphones on the left side.

Huawei has omitted a bezel for the Watch 4 Pro.

However, the edge between the display and the bezel is divided.

The band is 22mm wide and can be removed without tools.

Monitoring of the Watch: 

The Huawei Watch 4 pro has the hardware to monitor blood pressure, blood oxygen, and body temperature, which plays a huge role in high glucose warnings.

This is the first watch to feature non-invasive blood glucose monitoring.

It does not directly measure blood sugar.

Instead, they track other health metrics like heart rate, sleep, and activity levels that can be used to infer blood sugar levels.

High blood sugar levels can lead to a decrease in heart rate variability. 


It’s the best smartwatch for blood sugar monitoring, providing you with your daily health profile.

It also keeps you updated with fitness at the end of the day.

I surely recommend this device for diabetic patients.

My doctor suggested that I keep myself updated with the glucose levels in my body.

I decided to get myself a smartwatch rather than a blood test every day.

After long research, I learned about the Apple Ultra Watch, which helped me monitor my blood sugar through Dexcom CGM.

Without any needles, it allowed me to test my sugar level.


The Apple Watch Ultra is a versatile smartwatch with various features designed to help manage diabetes.

And this is the best way to monitor sugar levels.

One day, while scrolling, I learned about the Google Pixel Android smartwatch, and after reading such remarkable reviews, I ordered it.

I tried and tested it for a month; this was the best device with a blood sugar monitor.

The monitor works well and gives you accurate results.

It does not require physical blood tests.

The best smartwatch with a blood sugar monitor. 


Software and Performance:

Like other Wear OS devices, the pixel watch does not connect to the legacy Wear OS app.

Instead, you can download a dedicated pixel watch app when pairing the watch.

You can swipe up from home to see your notifications and down to access quick settings.

The customizable apps are now available on both the left and right of the Home Screen, looping back to your watch face when you reach the end in either direction.

Furthermore, each watch face has customizable elements, letting you choose between Arabic numerals or unlabeled dashes and pick your favorite.

You can also customize every watch face according to your preferences. 

Advanced Health Sensors:

The Pixel Watch can track your activity, workouts, and sleep, which can be easily imported into the Fitbit app.

However, there aren’t any standout features that are exclusive to the Pixel Watch.

The experience is similar to what you would find on other devices, for better or worse.

You can choose from about 40 different exercise types to manually track workouts; if you don’t choose one before your workout starts, Fitbit will broadly classify it with labels like walking or general “activity” once you’re finished.

Plus, your blood sugar is monitored, which benefits diabetic patients.

You are provided with your sugar intake chart every day right on your wrist. 


I wholeheartedly recommend using this smartwatch with a blood sugar monitor.

It checks your sugar level digitally and provides results throughout the day.

It also provides you with health and fitness profiles to help you stay updated with your health.

5. Fitbit Sense 2: (Best Advanced Health and Fitness Smartwatch with ECG App)

I’m a food blogger, and I test food every other day.

After eating such sugary items, I got diabetes last month.

One of my colleagues suggested I get a smartwatch to monitor my sugar level daily.

I was looking for a digital watch to monitor for painless tests.

One day, I got my hands on this Fitbit Sense 2.

This is the best monitor to keep your glucose level in check and gives you painless tests.

Plus, it does not require your blood sample for tests. 


Comfortable Redesign: 

Fitbit has improved its structure so that it’s more convenient for daily use.

The Sense 2 is lighter than its precursor, though you may not detect the weight change.

It was pretty stimulating to wear such a weightless device.

It’s comfortable for sleep tracking and all-day wear.

The updated design has totally different sensors both on the watch and screen. 

Stress Management: 

Fitbit has put a lot of struggle into stress tracking.

With the Sense 2, the company made significant modifications to the feature that sets it apart from other fitness wearables.

The Sense watches estimate stress through an EDA sensor.

EDA sensors notice tiny improvements in your skin’s exertion levels.

That and other metrics like heart rate deviation can demonstrate stress.

The stress data is also illustrated thoughtfully.

For example, you get a Stress Management score and a weekly summary.

The former looks at your body responses, sweat level, and sleep rituals to show how your incremental stress may affect you on a given day.

Your sleep patterns and blood sugar are monitored to help maintain throughout the day.

Blood sugar data is on your wrist when paired with your Android smartphone. 


I recommend this blood sugar monitor to keep an eye on your glucose level.

You are also provided with your health and fitness profiles throughout the day.

It’s a great advantage to manage your health.

6. Garmin Forerunner 245: (Best Budget GPS Running Smartwatch with Advanced Dynamics)

I started using this blood sugar monitor that helped me maintain my weight perfectly.

I wanted to lose weight for a long time, and my friend suggested that monitoring my sugar intake is the best way to lose weight so that I can count calories and lose weight.

This stunning smartwatch helps you monitor sugar intake without needles and blood samples.



I love the design of the Forerunner 245.

It’s incredibly user-friendly and comfortable, and it weighs only 38.5g.

With the standard five-button setup, navigating menus and controlling the device while on the move is a breeze.

The watch’s 240 x 240 full-color transflective screen offers clarity in all lighting conditions.

It’s the same high-quality display found on Garmin’s other high-end watches, giving the impression that the Forerunner 245 is a premium device.

Activity and Sports Tracking:

The Forerunner 245 has several new sports modes compared with its predecessor, with the most essential additions being pool swimming and strength training.

However, the watch is waterproof to 50m and provides a range of swim-specific stats.

Although it is a sports watch, first and foremost, the everyday activity tracking on the Forerunner 245 is also solid.

Alongside standard metrics stats such as steps, calories burned, and active minutes, it offers 24/7 stress tracking based on your heart-rate variability and Garmin’s Body Battery measurement.

Blood sugar readings are also provided after assessing your everyday sugar intake, which makes it quite convenient for diabetic patients.

It’s compatible with Dexcom CGM, so your data is streamlined directly from Dexcom to a particular watch. 


This is the best smartwatch with a blood sugar monitor.

It can make and receive calls.

Your sugar level is tested without the use of any blood tests.

Everything is displayed on its vibrant display, and you will be amazed by its quality.

I got diagnosed with diabetes, and it was pretty shocking to tackle such a situation.

My doctor suggested that I keep myself updated with the glucose levels in my body.

I decided to buy this smartwatch to monitor my glucose level.

After long research, I learned about the Apple Watch Series 7, which helped me monitor my blood sugar through Dexcom CGM.

Without any needles, it allowed me to test my sugar level. 


The Apple Watch Series 7 is a versatile smartwatch with various features designed to help manage diabetes.

Its design and innovative features can be utilized for different purposes. The accuracy and reliability perform most of what you need them to do, so I’m satisfied. This is one of the best Apple watches for blood sugar monitoring, is highly user-friendly, and performs well.

8. SAMSUNG Galaxy 3: (Best Smartwatch with Advanced Health Monitoring Using CGM Device)

I enjoy wearing watches and like to switch them out occasionally, so at the start of this year, I wanted to do the same because the watch I was wearing was getting old since I had worn it for 1.5 years.

I intended to get a well-known watch for being among the best smartwatches with blood sugar monitors, easy to use, and stylish.

I’m very glad I bought this watch after my friend suggested it to me.



The tactile bezel was useful and enjoyable when I tested the mechanism for my initial Samsung Galaxy Watch evaluation.

Swiping or attempting to push at the round display using the finger was not as effective as spinning the dial, which worked nicely with all side buttons.

The bezel stands up the second or third time around and feels considerably better as Samsung makes the Galaxy Watch 3 thinner.

Compared to the original Galaxy Watch, it is 15% lightweight, 14% slimmer, and 8% tinier.

However, compared to my Apple Watches, the 41mm, 1.7-ounce Mystic Bronze version I examined seems bulky.

It looks less similar to a high-tech watch and more like a conventional one.

The Samsung Galaxy Watch 3 stands as a fashionable piece, although I might forgo my Apple Watch for a fancy meal or a date night.

Even better, the Samsung Galaxy Watch 3 has authentic leather bands that complement the color of the case and give it a more upscale appearance.

Performance And Display:

The 360 x 360-pixel display of the Samsung Galaxy Watch 3 is clear, sharp sufficiently to be visible in bright sunshine, and is constantly on.

I’ll be honest, Apple Watch issues make me anxious.

The Galaxy Watch 3 has 40 complexities and 80,000 distinct watch faces, making things a lot easier for me. 

The numerous menus on the Galaxy Watch 3 are very customizable and filled with practical applications.

The bezel makes navigating simple, and I used the two keys to reach the place I needed to go.

What Makes It Best:

The Samsung Galaxy Watch 3 can monitor 40 different activities including workouts etc.

Seven of these can be recorded automatically, so you won’t necessarily need to choose the type of activity you’re doing in advance.

The Galaxy Watch 3’s built-in GPS precisely determined my regular course.

With an ECG monitor that has received FDA approval, the Galaxy Watch 3 can detect atrial fibrillation symptoms.

In a congested smartwatch industry, the Samsung Galaxy Watch 3 distinguishes out.

Samsung was able to build an equilibrium between both fashion and fitness tracking even though there are many fashionable smartwatches and great fitness trackers available today this watch stands out the most.


A rotatable bezel, ECG tracking, and fall warning are all features of the Samsung Galaxy Watch 3.

It is currently the best, most versatile Android smartwatch available.

  • Slimmer style compared to the original.
  • Real rotating bezels are back.
  • ECG readings with FDA approval.
  • Battery life is shorter.

9. Garmin Venu 2 Plus: (Best GPS Smartwatch with Blood Sugar Monitor Using Dexcom G6)

I was looking for a watch with my friend before going on a trip to the Maldives, so I came across this watch and after reading its specification I knew I had to buy it.  

It offers all the features I was hoping for.

The best watch with blood sugar monitor and other important functions is without a doubt this one.


Design And Performance:

Almost similar in appearance to the classic Venu 2, the Garmin Venu 2 Plus has a 43mm casing as opposed to the 40mm and 45mm cases of the original watch.

It strikes an excellent balance between size and comfort for smaller wrists, being spacious enough to accommodate the additional components of the modern watch.

Such as Venu 2, the Venu 2 Plus has a high durability of water rating of 5ATM, which qualifies it for bathing and swimming but is not suitable for diving or fast-paced watersports.

The touchscreen AMOLED screen on the Venu 2 Plus is vibrant, high-resolution, and appears responsive when being used.

Although there is an always-on mode, the battery life is shorter.

Battery Life:

The battery life will constantly vary according to how you utilize the watch’s different functionalities, especially SpO2 and Global positioning.

The watch can operate in smartwatch settings for up to nine days, power saving mode for up to ten days, Navigation, and music for a maximum of eight hours, or GPS only for 24 hours.

I recorded one workout routine while using the Venu 2 Plus, and I discovered that the charge depleted at a pace of about 10% each day, which is higher than the claimed figures and admirable for a potent AMOLED smartwatch.

What Makes It Best:

The inclusion of a mic is indeed the main distinction between Venu 2 and Venu 2 Plus.

As long as your smartphone is under the Bluetooth range, you can utilize voice assistance on your phone and place and receive calls.

During my tests using the watch linked to an Android smartphone, Google Assistant was able to interpret my queries without any issue because of the superb sound clarity from the mic.

In addition, even when I wasn’t exercising, I found myself utilizing Google Assistant far more frequently than I would normally because of how convenient it was to have it practically on my wrist.


With its inbuilt voice assistance and fitness functions, the Garmin Venu 2 Plus is among the best smartwatches and beats its competitors in the market.

  • Accept calls from the watch.
  • Voice assistance feature.
  • Bright display.
  • 10 days battery life.
  • Not too many sizes.


Is the Apple Watch capable of detecting blood sugar levels?

Blood sugar levels can be detected by the Apple watch. To display glucose data on the watch, you will need a compatible app and a Continuous Glucose Monitor (CGM), such as the Dexom G6, and G7.

Do blood glucose watches work? 

Watches that measure blood glucose need to be more accurate. They can only display blood glucose levels measured by an external continuous glucose monitoring (CGM) system. The watch’s accuracy depends on the accuracy of the CGM system it is linked to.

What wearable technology monitors blood sugar? 

These devices utilize tiny sensors to examine blood glucose and body temperature through the interstitial fluid without collecting blood. A CGM system takes readings regularly and sends them to your smartphone via a mobile app.

Is it possible to measure blood sugar levels with a Samsung watch?

Likewise, the Samsung watch measures blood sugar levels, but an app and CGM device are required to display the information.
