Choosing a health smartwatch

Every watch here has at least one medical-style sensor: an ECG app, blood pressure readings, or blood oxygen plus skin temperature. Beyond that, compare the alerts: irregular rhythm, high and low heart rate, and fall detection.

A watch is not a medical device replacement. Some health features are only cleared or available in certain countries. See also sleep tracking and smartwatches for seniors.

Frequently asked questions

Which smartwatch sensor matters most for heart health?

An ECG app with irregular rhythm alerts is the most useful for spotting atrial fibrillation. Heart rate alerts and resting heart rate trends add context.

Are smartwatch health readings accurate?

They're good for trends over weeks rather than single readings. For a diagnosis, see a doctor, who may use a smartwatch reading as a starting point.

Do health features need a subscription?

Core readings like heart rate, ECG, blood oxygen and sleep are free on most watches. Some brands charge for deeper insights, so check the subscription row.
