On this page (6 sections)
The best smart watch to detect AFib needs a clearly stated AFib feature, but none of these 5 watches has confirmed AFib detection in the product information available here. They describe everyday health tracking, such as heart rate and blood oxygen monitoring, which is different from a confirmed AFib feature.
If you need AFib monitoring, verify the exact model’s feature, phone and app requirements, and regional availability with its manufacturer before buying. A watch’s general heart rate sensor does not, by itself, show that the watch can detect AFib.

Which smartwatches have confirmed AFib detection?
None of these 5 smartwatches has confirmed AFib detection in the product information available here. Their described health features include heart rate, blood oxygen, stress, and blood pressure tracking, but those features are not proof of AFib detection.
This distinction matters when you’re choosing a device for a specific health feature. Check the exact model’s official support information for AFib or irregular rhythm detection, and confirm that the feature works with your phone and in your country.
If you’re comparing watches specifically for ECG functions, see our guides to the best ECG watches for Android and the best Apple Watch alternative for ECG. A watch that tracks heart rate is not automatically an ECG watch.
How we compared these smartwatches
We compared the described health features, phone compatibility, and everyday functions against what shoppers need to confirm for AFib monitoring. AFib detection is not confirmed for any of these picks, so the scores reflect their described everyday features and fit, not confirmed AFib capability.
Our score weighs specs and features against what you’re shopping for. For a device with a stated AFib purpose, compare it with ECG monitors for AFib detection and EKG monitors for AFib detection.
Those guides can help you consider other device types.

Best smartwatches for everyday health tracking
The Samsung Galaxy Watch 8 leads this group for Android users because its described features include heart rate tracking and a blood pressure function. None of these picks has AFib detection confirmed, so choose among them for general tracking only after checking the feature you need.
Samsung Galaxy Watch 8 40mm Bluetooth Smartwatch: Best for Android health tracking
- Heart rate tracking
- Blood pressure function requires cuff calibration
- Android phone compatibility
- Samsung Health Monitor app
A lightweight Android watch with heart rate tracking and a blood pressure function that requires cuff calibration. Its features do not confirm AFib detection.
Pros
- Heart rate tracking
- Works with Samsung and other Android phones
- Blood pressure feature uses cuff calibration
Cons
- AFib detection is not confirmed
- Blood pressure function requires a separate cuff
The Samsung Galaxy Watch 8 40mm is the strongest everyday health tracking option in this group for someone using an Android phone. It tracks heart rate, and its features include a blood pressure function through the Samsung Health Monitor app.
That blood pressure function needs calibration with a separate cuff. Samsung says calibration is required initially and periodically, every 28 days.
The function is not intended to diagnose or treat disease.
Its 30 g weight and thinner design may appeal if you want a lighter watch for day-to-day wear. It works with Samsung phones and other Android phones.
Its described features do not confirm AFib detection. Before buying this watch for a heart rhythm feature, verify whether the exact model, app, phone, and region support the feature you need.
Amazfit Active Max Smart Watch: Best for training and battery life
- Up to 25 days of battery life claimed
- 170+ workout modes
- Heart rate tracking
- iOS and Android compatibility
A training-focused smartwatch with heart rate tracking, workout modes, and a claimed battery life of up to 25 days. AFib detection is not confirmed.
Pros
- Heart rate tracking
- Works with iOS and Android
- Workout and running features
Cons
- AFib detection is not confirmed
- Battery life is a brand claim
The Amazfit Active Max is a better fit if you want general health tracking alongside workout features. It includes heart rate tracking, more than 170 workout modes, built-in positioning, and iOS and Android compatibility.
Amazfit claims up to 25 days of battery life. Actual battery life can vary, so treat that as a claim rather than a guarantee.
Its 1.5 in AMOLED display and onboard maps also suit users who want activity information on their wrist.
AFib detection is not confirmed. The BioCharge score is described as reflecting workouts and stress levels, which is different from a stated AFib feature.
Choose this model for training and daily tracking if those are your priorities. For running-focused alternatives, see Suunto watches for running.
If AFib detection is the reason you’re shopping, check the exact feature and app support before considering it.
JeeJTek Smart Watch for Men Women: Best for calls and quick replies
- Heart rate monitor
- Blood oxygen monitor
- Stress monitor
- Quick replies for Android
This watch combines calls and notifications with heart rate, blood oxygen, and stress tracking. Its health features do not confirm AFib detection.
Pros
- Heart rate tracking
- Calls and notifications
- Quick replies available for Android
Cons
- AFib detection is not confirmed
- Quick replies are limited to Android
The JeeJTek Smart Watch is aimed at everyday connectivity, with calls, message alerts, and quick replies for Android users. It also describes heart rate, blood oxygen, and stress monitoring, plus sleep tracking.
Its 1.83 in TFT LCD screen and compatibility with iOS and Android may make it useful as a general-purpose watch. The quick reply function is limited to Android, and the watch does not have built-in GPS.
Its health features do not confirm AFib detection. A heart rate monitor is not the same as a confirmed AFib feature, so don't rely on this watch for that purpose unless the manufacturer confirms support for your exact model and phone.
ICOMTOFIT Smart Watches for Women: Best for basic daily health tracking
- Heart rate tracking
- Blood oxygen and stress monitoring
- Sleep tracking

- ICOMTOFIT says it is for daily reference, not a medical device
The ICOMTOFIT watch provides everyday tracking features, including heart rate, blood oxygen, stress, and sleep monitoring. It also supports more than 100 sports modes and pairs with iOS and Android phones.
ICOMTOFIT describes this watch as a daily health reference, not a medical device. Its 1.83 in touchscreen and call and notification features may suit someone who wants basic tracking and phone alerts.
AFib detection is not confirmed. If you’re considering this model for a specific heart rhythm feature, verify that feature directly before buying.
DEKELIFE Smart Watches for Men: Best for a broad set of wellness metrics
- Heart rate and blood oxygen tracking
- Blood pressure and body temperature metrics
- 140 sports modes
- iOS and Android compatibility
DEKELIFE describes wellness metrics including heart rate and blood pressure. AFib detection is not confirmed.
Pros
- Several health and activity metrics

- Works with iOS and Android
Cons
- AFib detection is not confirmed

The DEKELIFE watch describes a broad set of wellness metrics, including heart rate, blood oxygen, blood pressure, body temperature, sleep, stress, and HRV. It also offers 140 sports modes, call features, and iOS and Android compatibility.
Its 1.95 in AMOLED display is the largest described here. DEKELIFE claims 4–7 days of normal use after charging, but its product information does not confirm how each health metric is measured or validated.
AFib detection is not confirmed. Don't assume that a broad set of wellness measurements includes an AFib feature.
Check the exact model's support information first.
What is the difference between heart rate tracking and AFib detection?
Heart rate tracking reports how fast your heart is beating. AFib detection refers to a feature specifically intended to identify signs of an irregular rhythm associated with atrial fibrillation, and it may rely on a different sensor, recording, or software feature.
The watches here describe heart rate tracking, but their features do not confirm AFib detection. A heart rate measurement, blood pressure estimate, or general wellness score is not proof that a watch detects AFib.
For a closer look at a specific model, read our Withings ScanWatch Light review. For another Withings model, see the ScanWatch Nova review.
Check the manufacturer's support pages for the features and phone requirements of the exact version you plan to use.
What should you verify before buying a watch for AFib?
Confirm AFib support for the exact model number, compatible phone, required app, and your region. For Fitbit's ECG details, see Fitbit ECG features.
Also check whether the feature is an ECG recording, an irregular rhythm notification, or another type of monitoring, since the wording can describe different functions. If you need to save ECG records as data, see ECG apps that export CSV files.
For a model-specific example, see Apple Watch models with ECG.
Look for the manufacturer's instructions on how to start a reading, how alerts are shown, and what steps to take after an alert. If you’re choosing a wearable for a health concern, ask a health professional how to use and interpret its readings.
Don't infer AFib support from labels such as heart rate monitor, health tracking, or blood pressure monitoring. These 5 watches have other described tracking features, but AFib detection is not confirmed for them.
Which watch should you choose?
Choose the Samsung Galaxy Watch 8 if Android compatibility, heart rate tracking, and a cuff-calibrated blood pressure function fit your everyday needs. For a separate comparison of overnight features, see watches for sleep tracking.
Choose Amazfit Active Max for training features, or JeeJTek for calls and Android quick replies.
For AFib detection, choose only a watch whose manufacturer confirms the feature for your exact model, phone, and region. None of these 5 picks has that confirmation, so use the ECG smartwatch comparison guide to plan your next check.

Frequently asked questions
Can a smartwatch detect AFib?
Some smartwatch models offer features intended to identify signs of atrial fibrillation. Support depends on the exact model, phone, app, and region, so check the manufacturer's health feature information for your setup.
A heart rate sensor alone does not confirm AFib detection.
Does a high heart rate reading mean AFib?
No. A heart rate reading shows how fast your heart is beating, but it does not by itself identify a heart rhythm or diagnose AFib.
If you have symptoms or concerns, discuss them with a health professional.
Seek urgent care for severe or sudden symptoms.
Are the watches in this roundup confirmed to detect AFib?
No. These 5 watches have features such as heart rate, blood oxygen, stress, and blood pressure tracking, but AFib detection is not confirmed for them.
Verify the exact watch and app features with the manufacturer before you buy.
What should I check before buying a watch for AFib detection?
Confirm that the exact model has an AFib feature, that it works with your phone, and that it is available in your country. Check whether it uses an ECG recording, an irregular rhythm notification, or another method, since those features are not interchangeable.
Ask a clinician how to interpret any alert.
