Best 2026 Wearable Tech for ECG functionality

#1 Apple Watch Series 12
4.5

The expanded sensing surface appears to improve ECG capture, including a smoother experience for one user who had trouble with an older Apple Watch.

Pros: value for money, heart rate accuracy

Cons: data privacy

#2 Garmin Fenix 9
4.0

Manual ECG recording is simple and reassuring for a tester who shares results with a cardiologist. The lack of passive Afib detection limits its appeal beside competing health watches.

Pros: battery life, mapping and navigation

Cons: value for money, LTE connectivity

#3 Samsung Galaxy Watch Ultra 2
4.0

ECG readings generally worked as expected and one comparison produced results similar to a dedicated Kardia device. It remains a wellness feature rather than a substitute for clinical diagnostic equipment.

Pros: battery life, comfort

Cons: value for money, charging speed

#4 Google Pixel Watch 5
4.0

ECG remains one of the more immediately useful health tools, especially compared with newer trend-based metrics that need longer baselines.

Pros: software smoothness, style and design

Cons: value for money, wellness insights

#5 Garmin Fenix 9 Pro
3.5

The wrist ECG can be simple to capture and reassuring to share with a cardiologist. One owner encounters a repeatable freeze after taking a reading.

Pros: mapping and navigation, battery life

Cons: value for money, software smoothness

#6 Amazfit Cheetah 2 Pro
2.3

ECG functionality was a weakness because reviewers noted the feature is absent and that Garmin offers superior ECG-related capability.

Pros: GPS accuracy, battery life

Cons: band quality, smartwatch features

#7 Amazfit Balance 3
2.0

ECG remains absent because the watch retains the older BioTracker sensor generation. One reviewer considered this an overdue omission for the Balance line.

Pros: battery life, brightness

Cons: fit, third-party app support

#8 Amazfit Cheetah 2 Ultra
2.0

ECG is a clear missing health feature; one reviewer called its absence one of the few serious criticisms.

Pros: battery life, value for money

Cons: reliability

#9 Garmin Forerunner 170
2.0

ECG is not available on the Forerunner 170, and reviewers note that buyers must move to a pricier Garmin to get it.

Pros: value for money, battery life

Cons: mapping and navigation, materials quality

#10 Samsung Galaxy Watch 9
2.0

ECG is useful as part of Samsung's broad health suite, but its Galaxy-phone requirement sharply limits access for users of other Android brands.

Pros: software smoothness, wellness insights

Cons: battery life, charging speed

#11 Polar Street X
1.5

ECG was also a limitation: reviewers framed the missing ECG sensor as understandable at the price but still a downside for users who prioritize health metrics.

Pros: value for money, flashlight usefulness

Cons: user interface
