How to check your heart rate and breathing using your Android phone

Smartphones can be great tools for keeping track of health and fitness data. Google Fit on Android devices makes it easy to track not only your exercises but also your heart and breathing rates without the need for special devices.

All you need is the Google Fit app and an Android phone to use these features. They were first introduced on Google Pixel Smartphones, so they may not be available on every single Android device right now.

How to export your Google Fit data

First open the Google Fit app on your Android device and sign in with your Google account.

The first time you sign in, you will be asked to provide some information about yourself, including your gender, birthday, weight, and height. When you’re done, tap Next.

You can also turn on automatic activity tracking if you want, but it is not required.

With the initial setup done, we are now ready to use the heart rate and breath rate functions.

How accurate are these measurements? Google says they are not intended for medical diagnosis or medical evaluation. You won’t get the same level of accuracy as real medical equipment. Still, it’s good for the occasional health and fitness tracking.
