Health data types

Google Fit has health data types for measurements related to managing general health (as opposed to fitness).

Data types list

You can learn more about the health data types, and their fields, from the Android reference documentation. Fields with the unit enum have a list of accepted values to choose from. Only use one of the allowed values to successfully read and write data.

Getting permission to read and write health data

Note: Google has temporarily stopped taking new requests to write to health data types. We've updated our policy and the process for reading and writing data will change when policy enforcement starts.

To read health data, follow these steps:

1. Make sure your app complies with Google's API User Data Policy and the Google Fit Developer and User Data Policy.

2. Apply for your consent screen to be verified by Google.

   Note: If your app isn't verified when it requests access to a sensitive OAuth scope, Google will assess its risk and apply quotas accordingly. Your users might also see warning screens. You can still test your app but the quotas will restrict how many new users you can get.

If your app gets verified, it can read health data that users have consented to being read.
