# Google Fit vs Health Connect SDK connection types?

The two [connection types](https://docs.tryterra.co/health-and-fitness-api/mobile-only-sources) differ in what they read:

* **`Connections.HEALTH_CONNECT`** retrieves all data in Health Connect, regardless of which app wrote it.
* **`Connections.GOOGLEFIT`** retrieves only the data Google Fit itself synced into Health Connect.

Both trigger the Health Connect permission screen. Use `HEALTH_CONNECT` if you want the full dataset from every contributing app.
