Best 2026 Smartwatches for ECG functionality

#1

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

#2

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.

#3

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

#4

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

#5

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

#6

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

#7

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

#8

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.

#9

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.
