Individuals with diabetes can greatly benefit from using smartwatches to support a healthy 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 monitors the patient’s blood glucose levels and sends the data to their watch or smartphone.
Smartwatches can greatly benefit people with diabetes; however, there are many options on the market.
As a result, determining which smartwatches are best suited for managing diabetes can be challenging.
The top smartwatches for diabetes management are listed below to help you make an informed decision.
We’ve conducted an extensive study to shorten our list.
Which are the Best Smartwatches with a blood sugar monitor?
Here are my recommended top 8 Best Smartwatches with Blood Sugar Monitors:-
1. Garmin Venu 4: (Best for Diabetics Who Exercise Regularly)
A personal trainer with Type 1 diabetes described the specific problem the Garmin Venu 4 solved during client sessions.
She would start a workout activity on the watch, and her Dexcom glucose reading would appear as a data field on the same screen as her heart rate and timer.
At a glance, during a set, she could see whether her glucose was stable, rising, or dropping, without switching screens, opening apps, or touching her phone.
When glucose started dropping mid-session, she had enough early warning to take carbs before her performance was affected.
She described it as seeing the complete picture of the performance for the first time.
Dexcom on Garmin’s Platform:
The Garmin Venu 4 accesses Dexcom G7 data via the Dexcom Connect IQ widget, available in Garmin’s Connect IQ store.
Once installed, the widget displays the current glucose level, trend direction, and a 3-hour history on a dedicated watch screen.
During any exercise activity, glucose can be added as a data field alongside standard metrics, meaning heart rate, pace, distance, and glucose all appear on the same screen simultaneously.
This exercise-specific integration is where Garmin’s platform offers something genuinely different from other options on this list.
During a run, the Dexcom data field updates every five minutes alongside the running metrics.
After the session, Garmin Connect shows the workout data with a glucose overlay, so you can see exactly how your blood sugar responded to each phase of the session across your entire data history.
Over time, this builds a personalised picture of how your body responds to different exercise types, intensities, and durations.
Body Battery and Glucose Management Together:
Body Battery synthesises overnight HRV, resting heart rate, training load, and sleep quality into a single morning energy score.
For people managing diabetes, this score takes on additional meaning because the same physiological factors that drive poor Body Battery also affect glucose control.
A low Body Battery score due to poor sleep correlates with elevated morning cortisol and insulin resistance, which many people with diabetes experience.
Having a number that reflects this biological state before the day starts helps explain why some mornings require more aggressive management than others.
Lifestyle Logging allows you to manually record meals, alcohol, caffeine, and stress events, then review how these inputs correlate with your health metrics over time.
For diabetics trying to understand which foods and habits drive glucose spikes, connecting manual logs to automated metrics in Garmin Connect builds a data-driven picture of personal responses rather than relying on population averages.
Health Status monitors your personal baseline across HRV, sleep, temperature, and other overnight metrics, alerting you when readings drift outside your normal range.
For people with diabetes who are also managing other health conditions or experiencing periods of increased stress or illness, this alert provides early warning of physiological changes before they manifest as symptoms or changes in glucose patterns.

2. SAMSUNG Watch 8: (Best Watch for Measuring Blood Sugar + More Health Insights)
On my friend’s recommendation, I upgraded to the new Samsung Galaxy Watch 8 mainly to track my sugar levels and keep better tabs on my overall health.
After years of painful finger-pricks and lab visits, I was looking for something smarter and less invasive.
This watch still pairs with tools like Dexcom for blood glucose monitoring, but the added health metrics took me by surprise, especially things like antioxidant level tracking and vascular load analysis, which I never thought I’d care about until I started using it.
And yep, the built-in GPS tracking is solid.
I’ve used it on runs, hikes, and even casual walks, and it’s extremely accurate.
WHAT DO WE GET FROM THESE?
Built to Last (and Look Good Too):
The Galaxy Watch 8 keeps the durable design Samsung is known for, with a slim aluminum case and that sapphire crystal glass face.
It feels premium but isn’t too flashy.
The display is stunning — seriously, 3,000 nits of brightness makes it readable even under harsh sunlight.
What really impressed me was how smart the watch actually feels.
It goes beyond tracking — it guides.
With AI-powered coaching, detailed sleep reports, and advanced wellness tracking, it’s more like having a health assistant on your wrist.
Oh, and it still supports the Dexcom CGM device, so blood sugar monitoring remains part of the package, especially helpful for anyone managing diabetes.
New Sensors & Smarter Insights:
Beyond the usual fitness stuff, Samsung went further with bioelectrical impedance analysis (BIA), heart rate monitoring, SpO2, and even skin temperature sensing.
I ran a 12-minute test, and the watch built a custom fitness plan just for me.
The Running Coach gave me real-time suggestions during my jog, which felt weirdly helpful — almost like someone whispering coaching tips in my ear.
I also tested the new antioxidant level checker.
All I had to do was take the watch off and hold my thumb on the sensor for five seconds.
My first score? “Low.” Time to eat more persimmons, I guess.
Conclusion:
If you’re dealing with diabetes or just want a powerful wellness companion, this is hands down the best Samsung smartwatch right now.
It’s painless, personalized, and packed with features that actually matter.
You still get accurate Dexcom CGM pairing — but with way more health insights on top.
Honestly, it feels like the smartest watch Samsung’s ever built.

4. Apple Watch Series 11: (Best Smartwatch as a Blood Sugar Companion)
The Apple Watch Series 11 does not measure blood sugar by itself.
What makes it one of the best choices for people who want on-wrist glucose info is how well it works with real Continuous Glucose Monitors (CGMs).
With direct CGM connections (where supported) and fast alerts on the wrist, the Series 11 becomes a very useful companion display—fast to glance at during workouts, driving, or sleep—while the actual glucose sensing is still done by an approved CGM device.
How it works: Companion display vs sensor
Smartwatches fall into two categories for glucose:
- True glucose devices (FDA-cleared CGMs) that use an under-skin sensor and report real glucose numbers.
- Watch displays that show data sent from those CGMs or from the phone app.
The Apple Watch Series 11 is in the second group.
It shows CGM values, trends, and alarms from supported CGMs (for example, Dexcom G7’s direct-to-watch feature), so you can glance at numbers and trend arrows without opening your phone.
That convenience matters a lot in daily life, but remember: the watch displays CGM data — it does not sense glucose itself.
Why Series 11 stands out for glucose monitoring:
Direct CGM integrations are real now. Dexcom announced direct-to-Apple Watch support for the G7, which removes the need to keep your phone physically close for basic alerts and readings. That lowers friction and makes wrist checks genuinely convenient
Stable platform and fast alerts. watchOS and Apple’s hardware keep notifications and haptics reliable, so low/high warnings reach your wrist with minimal delay. Reliable haptics are essential for safety when you can’t look at the screen.
Ecosystem and data export. Apple Health makes it straightforward to export or share CGM charts with clinicians if you need them for diagnosis or adjustments. Apple’s seamless backups and privacy controls are useful when you manage medical data.
Safety & regulatory reality:
The U.S. FDA has made a clear and important statement: no smartwatch or smart ring is authorized to measure blood glucose by itself.
That means any device claiming needle-free glucose readings should be treated with caution.
Use only FDA-cleared CGMs (or your glucose meter) for medical decisions.
The Apple Watch + CGM route is safe only because the CGM is the sensor and the watch is a display/alert device.
Where Apple leads, and where others catch up:
Apple Watch (Series 11): strong direct CGM support (Dexcom), best iPhone/Health integration, reliable haptics, and UI. Great for iPhone users who want a tidy on-wrist view and quick alarms.
Google / Wear OS watches (Pixel Watch 4, Pixel Watch 3/5): good third-party app support (Gluroo, others) and improving battery life, but CGM direct support varies by vendor and often still relies on phone bridging. On Android, they’re useful, but experience depends on the CGM app ecosystem.
Samsung watches: can show CGM notifications via phone apps; hardware and ecosystem tie-ins vary by region and vendor. Some CGM companies prioritize Apple first.
What to expect:
Night checks and alarms: When a CGM is paired directly, the Series 11 can vibrate and show trend arrows while you sleep. That gives fast cues for potential hypos overnight. In real tests from multiple sources, direct watch alerts reduced the friction of waking and checking the phone.
During exercise: glanceable glucose numbers on the wrist help you decide whether to eat carbs mid-session. Trend arrows add context beyond a single number.
Accuracy: accuracy depends entirely on the CGM sensor and its calibration. The watch does not change the sensor’s precision; it only displays what the CGM reports.
Set up tips: Get the most from Series 11 + CGM
- Use an approved CGM (Dexcom G7, Abbott Libre, etc.) and install its latest app on your iPhone first. Confirm the app supports direct watch display or reliable notifications.
- Enable direct watch pairing if your CGM supports it (Dexcom G7 has direct-to-watch capability). This avoids relying on phone proximity for basic readings.
- Set strong haptics and loud alerts for overnight lows. Test alerts while awake to make sure you’ll feel them during sleep.
- Verify numbers first. Cross-check watch values against your CGM phone app (and a fingerstick when needed) in the first few days to ensure everything is routed correctly.
- Save and share suspicious patterns with your clinician; export CGM/Health data for meaningful discussion.
Conclusion:
If you or someone you care for uses glucose-lowering medication, never act on a non-approved device or unconfirmed reading.
Use the CGM/phone as the source of truth for dosing.
Treat the Apple Watch Series 11 as an excellent, convenient display and alert system that reduces friction and speeds awareness, but not as a replacement for approved medical devices.
Key specs:
| Item | Note |
| Glucose sensing | No onboard glucose sensor — relies on external CGM. |
| CGM support | Direct-to-watch capability available for some CGMs (e.g., Dexcom G7). |
| Alerts | Haptics + on-screen alarms via watchOS; configurable thresholds in CGM app. |
| Data export | Works with Apple Health and can export/share readings for clinicians. |
5. Garmin Fenix 8: (Best for Athletes and Outdoor Enthusiasts with Diabetes)
A mountain runner with Type 1 diabetes described what the Garmin Fenix 8 changed about racing in alpine environments.
On a long mountain ultra, his phone was deep in a waterproof bag in his pack.
With the Dexcom Connect IQ data field running on the Fenix 8 and his phone in Bluetooth range inside the pack, glucose readings were updated on his wrist every five minutes throughout the race.
He could check his level at any aid station, during any climb, and at the finish line without touching the pack.
He crossed the line, knowing his glucose had been 94mg/dL for the final descent.
CGM During Serious Activity:
The Fenix 8 handles CGM data in the same way as the Venu 4, through the Dexcom Connect IQ widget and phone proximity.
Where the Fenix 8 differs is in the context it provides around that glucose data.
ClimbPro displays the gradient and remaining elevation of each climb on a route.
The barometric altimeter tracks altitude changes that affect glucose management at height.
The LED flashlight covers pre-dawn starts when reading a wrist display requires actual illumination.
The TopoActive preloaded maps mean that navigation in remote terrain does not require the phone to be accessible, even though the phone still needs to be nearby to access CGM data.
For athletes managing Type 1 diabetes during long outdoor events, the Fenix 8’s 10 ATM water resistance, MIL-STD-810 durability, and multi-week battery life in smartwatch mode mean the watch handles any environmental condition without the wearer having to manage it.
The solar charging on the Solar variant extends this further, making week-long expedition charging essentially autonomous under strong outdoor light.
The Fenix 8 AMOLED display reads clearly in full mountain sun, which matters when you are checking a glucose number and a gradient simultaneously on a demanding climb.
Previous Garmin displays required the wearer to step into shade or cup the screen to read it in bright conditions.
The AMOLED eliminates this completely.
Who Should Not Buy This:
If the premium price over the Venu 4 is not justified by your activity level and outdoor use case, the Venu 4 provides the same CGM platform at considerably lower cost.
If you need direct-to-watch glucose data without phone proximity, the Apple Watch Series 11 with Dexcom G7 is the only current option. For everyday urban diabetes management without serious outdoor activity, the Fenix 8’s advantages are not relevant to daily use.
For a broader comparison of how the Fenix 8 handles navigation and fitness tracking for outdoor athletes, the review at best-smartwatches-for-hiking covers outdoor performance in detail.
Specifications:
| Feature | Details |
|---|---|
| CGM Compatibility | Dexcom G7 via Connect IQ widget and phone |
| Display | AMOLED 454×454 pixels, 47mm |
| Battery | 16 to 18 days smartwatch, extended with Solar |
| GPS | Multi-band dual-frequency |
| Maps | Preloaded TopoActive |
| Navigation | ClimbPro, turn-by-turn, TracBack |
| Water Resistance | 10 ATM |
| Build | MIL-STD-810 |
6. Apple Watch Ultra 3: (Best for Type 1 Diabetics on Insulin Pumps)
An intensive care nurse with Type 1 diabetes described what the Apple Watch Ultra 3′s battery meant for her specifically.
She works 12-hour shifts, during which charging a watch is genuinely not possible.
Previous Apple Watch generations required a charge every 18 hours, which, for her, meant choosing between overnight CGM monitoring and arriving at a shift with a full battery.
She could not reliably do both.
The Ultra 3’s 42-hour battery removed that calculation.
She charges it after every shift, overnight CGM monitoring runs continuously, and the CGM alert haptics reach her wrist during shifts without her touching her phone.
Battery Life and Type 1 Management:
The relationship between the Apple Watch Ultra 3’s battery and the specific demands of intensive Type 1 diabetes management is more practical than it might appear from its specifications.
People on insulin pump therapy or using closed-loop systems like the Tandem t:slim X2 or Omnipod 5 often have multiple devices to charge.
Adding a watch that requires daily charging to a pump, a CGM receiver, and a phone creates genuine charging fatigue.
The Ultra 3’s 42-hour standard battery life and 60-hour optimised mode mean most people charge it every two days, reducing the overall device-management burden.
The direct-to-watch Dexcom G7 integration on the Ultra 3 is identical to the Series 11.
The CGM sensor maintains its own Bluetooth connection directly to the watch, independent of the iPhone.
For pump users whose phone runs automated insulin-delivery software and cannot be left idle, having the watch receive CGM data independently means the phone can stay focused on pump communication without the watch relying on it.
The 49mm titanium case with 100-metre water resistance handles the demands of an active lifestyle without concern.
For triathletes, open-water swimmers, and outdoor athletes managing Type 1, the build means the watch goes into the water the same way as everything else, with no special considerations.
Two-Way Satellite Messaging:
The Ultra 3 adds two-way satellite SOS and messaging, available without a cellular signal.
For people with Type 1 diabetes who spend time in remote locations, alone, this is a genuine safety feature.
A severe hypoglycaemic event in an area without phone coverage is a medical emergency.
The ability to communicate and request emergency assistance via satellite adds a safety layer that no other watch on this list provides.
For everyday urban diabetes management, satellite messaging is a premium that rarely activates.
For specific user profiles, including hikers, trail runners, solo campers, and rural residents with Type 1 diabetes, it represents meaningful additional security.
Who Should Not Buy This:
Android users cannot use this watch. If everyday charging is not a constraint and the premium price is not justified by your specific needs, the Apple Watch Series 11 provides identical CGM integration at a lower cost.
If your activity does not include remote environments or extended periods away from charging, the Ultra 3’s unique advantages over the Series 11 may not apply to your situation.
For a broader look at how the Ultra 3 handles training load and recovery alongside CGM monitoring for active diabetics, the detailed comparison at best-smartwatches-for-triathlon covers the Apple Watch in multisport contexts.

7. Google Pixel Watch 4: (Best Smartwatch with Advanced Health Monitoring Using a CGM Device)
BODY:
The Pixel Watch 4 is a great Wear OS smartwatch for people who want a modern watch that can show continuous glucose data from a proper CGM system.
Important point first: the Pixel Watch 4 does not measure blood sugar itself.
There is no non-invasive glucose sensor built into the watch.
Instead, the Pixel Watch 4 works as a companion display for FDA-cleared CGM systems (Dexcom, FreeStyle Libre, and others) through phone apps and third-party Wear OS apps/watchfaces.
That makes it very useful for quick checks on the wrist, but you must rely on an approved CGM or meter for dosing and medical decisions.
BATTERY:
Google improved battery life, and the new Pixel Watch 4 can last a full day with normal use.
If you enable continuous CGM readouts on a watch face or run background apps that poll the phone, expect the battery to fall faster than a basic watch face.
In practice, a full day plus some spare hours is realistic; heavy always-on displays and active CGM complications shorten that window.
Check your settings if you want multi-day CGM visibility.
How glucose data reaches the watch:
There are two common ways glucose shows up on the Pixel Watch 4:
Official CGM app + phone notifications. Many CGM systems send alerts and summary notifications from the phone to your watch. That gives quick warnings for highs and lows, but often needs the phone nearby. Dexcom and FreeStyle Libre both provide mobile apps that route alerts to smartwatches via the phone.
Wear OS companion apps and watchfaces. Third-party tools like Gluroo or watchfaces designed for CGM (for example, Gluroo’s Wear OS ecosystem) let you show real-time glucose values and trends directly on a Pixel Watch face, provided the phone app is connected to the CGM. These tools expand what you can see on the wrist but rely on the phone and the CGM backend to feed accurate numbers. Expect occasional compatibility quirks depending on the CGM model and OS versions.
HEALTH: (what this setup actually gives you)
- Real-time glucose values and trend arrows on the watch face for fast checks while you are working, exercising, or driving.
- Alerts for high and low glucose are delivered as haptics and on-screen notifications when your CGM sends an alarm.
- At-a-glance history with simple trend lines or small charts on some watchfaces so you can decide whether to pause exercise, take carbs, or check with your phone.
Remember: these are visual and notification tools only. The watch is a viewer and alert device. For insulin dosing or clinical choices, use your CGM’s official reader or phone app and follow medical advice. The FDA explicitly warns people not to trust watches or rings that claim to measure glucose noninvasively.
How to use Pixel Watch 4 as a glucose companion:
- Pick a supported CGM. Dexcom and FreeStyle Libre have established mobile apps and follow-up systems that can send wrist alerts. Confirm the CGM model and app compatibility for Android and Wear OS.
- Install the phone app first. Get the official CGM mobile app running and sharing notifications. Many watch solutions need the phone app as the primary data source.
- Try a dedicated watchface or third-party app (Gluroo, SugarPixel, etc.). These can place glucose values and trend arrows directly on your watchface for instant visibility. Expect occasional setup fiddles; read the developer help pages.
- Set strong alarms and haptics. Wrist vibration is helpful when you can’t look at your phone. Test alarm loudness and vibration placement.
- Verify accuracy on your first days. Cross-check watch values with the CGM phone app and, if you use them, occasional fingerstick meters, especially when using third-party integrations.
WHY PIXEL WATCH 4 IS USEFUL:
Apple Watch offers tighter, sometimes more direct support for some CGMs (It can receive direct Dexcom G7 readings in some setups).
On Wear OS, the situation has historically been more fragmented, but it is improving.
Pixel Watch 4 benefits from Wear OS apps like Gluroo and from Google’s updates that improve watch performance and battery life.
If you want a modern Wear OS watch that can display CGM data cleanly and you use Android, the Pixel Watch 4 is one of the best wrist options today — as long as you accept the companion role and pair it with an approved CGM.
SAFETY & REGULATORY REMINDERS:
The FDA warns consumers not to buy or use smartwatches or rings that claim to measure blood glucose without approved sensors. Never rely on a watch alone for medical dosing.
If a gadget promises needle-free glucose readings, approach it skeptically and check for FDA approval.
Use CGM readings and watch alerts as decision support, not as the sole source for critical insulin or treatment decisions. Confirm with your official CGM app and follow clinical guidance.
SPECS:
| Feature | Pixel Watch 4 (high level) |
| OS | Wear OS 6/5+ with Pixel optimizations and Gemini features. |
| Display | Domed Actua 360, larger and brighter than previous Pixel watches. |
| Battery | Up to multiple tens of hours depending on use; active CGM watchfaces reduce runtime. |
| Health sensors | HR, SpO₂, temperature, accelerometer, GPS. No glucose sensor. |
| CGM support | Works as companion display for Dexcom, FreeStyle Libre, and others via phone apps and third-party Wear OS apps like Gluroo. Compatibility varies by CGM model and app. |
8. Garmin Forerunner 970: Best for Runners and Triathletes with Diabetes
A competitive age-group triathlete with Type 2 diabetes described the Forerunner 970 as the watch that finally made her race day simpler rather than more complicated.
Her phone ran the Dexcom G7 app and sat in her transition bag throughout the event.
With the phone maintaining a Bluetooth connection to both the CGM sensor and the watch during each leg, glucose readings appeared on the Forerunner’s watch face throughout the swim, bike, and run, without any setup changes at each transition.
She saw her glucose at every mile marker of the run and finished the race with a complete glucose overlay of the entire event in Garmin Connect.
Dexcom During Triathlon and Running Events:
The Forerunner 970 supports the Dexcom Connect IQ widget across all triathlon activity modes, so glucose data continues to display during each leg of a triathlon as long as the phone remains within Bluetooth range in the transition area or on the bike.
The auto-transition detection that switches the watch between swim, bike, and run tracking does not interrupt the Dexcom data field, which continues updating independently.
During standard running sessions, the Dexcom data field appears on a configurable data screen alongside running power, heart rate zone, cadence, and ClimbPro data.
The watch’s AMOLED display reads clearly in direct sunlight during races and training alike.
Heart rate accuracy across running intensities is among the most reliable of any optical sensor tested on the wrist, which matters for people with diabetes who use heart rate zones to manage exertion and its effect on glucose.
The Garmin Triathlon Coach feature, available on the Forerunner 970, creates adaptive training plans covering swim, bike, and run that adjust based on your daily Training Readiness and Body Battery scores.
For a triathlete managing Type 1 diabetes, where training load directly affects insulin sensitivity and glucose variability, a training plan that responds to your actual daily readiness, rather than a fixed schedule, removes one source of glucose-management complexity.
FTP testing and power curve tracking for the bike leg, connected with Dexcom glucose data in Garmin Connect, allowing you to review how your power output correlates with your glucose levels across your training history.
For diabetics who train with power on the bike, this connection between performance data and glucose data is valuable for understanding how specific sessions affect insulin needs.
Who Should Not Buy This:
If you do not run or compete in triathlons and primarily want CGM monitoring for daily life and casual activity, the Venu 4 provides the same Garmin CGM platform with a more lifestyle-oriented design at a lower cost.
If phone-free direct CGM data is the requirement, Apple Watch Ultra 3 with Dexcom G7 is the only relevant option for extended events.

FAQs:
Is the Apple Watch capable of detecting blood sugar levels?
The Apple Watch can detect blood sugar levels. To display glucose data on the watch, you will need a compatible app and a Continuous Glucose Monitor (CGM), such as the Dexcom 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 use tiny sensors to measure blood glucose and body temperature through interstitial fluid without drawing 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 a CGM device are required to display the information.
