Track your heart rate with your watch

You can use a Wear OS watch to take heart rate measurements. In the Google Fit app, you can track your heart rate for a workout or over time.

Important: Fit won’t save heart rate data for children under 13 (or the applicable age in your country).

Get started

To monitor your heart rate, you need a watch with a heart rate sensor. Some examples include:

• LG Watch Sport
• Huawei Watch 2
• Montblanc Summit
• Fossil Q Control
• Misfit Vapor

You can also use a Bluetooth heart rate sensor, like a chest strap.
Note: This feature is only available on Wear OS 3 and below.

Fix a heart rate monitor that’s not working

If your heart rate monitor isn't working, try these steps:
