GymRats no longer connects to Fitbit directly. Instead, Fitbit shares your workouts with your phone's health app, and GymRats reads them from there. On iPhone that is Apple Health. On Android it is Health Connect. Once both sides are switched on, Fitbit workouts show up in GymRats the same way they did before.
Before you start, make sure the Google Health app (this is the new name for the Fitbit app) is up to date. Apple Health sharing needs version 5.05 or later and iOS 16.4 or later.
On iPhone
Step 1. Share Fitbit data with Apple Health
1. Open the Google Health app and sign in with your Google Account.
2. Tap Connections, then Apps and services.
3. Choose Apple Health and tap Turn All Categories On, or at least Workouts, Steps and Active Energy.
4. Tap Allow.

Step 2. Let GymRats read Apple Health
1. Open GymRats, go to Settings, then My Devices, then Apple Health.
2. Turn on the connection. When Apple Health asks for permissions, choose Turn On All so GymRats can see your workouts.

On Android
Step 1. Share Fitbit data with Health Connect
1. Open the Google Health app and sign in with your Google Account.
2. Tap Connections, then Partner apps.
3. Under Add connections, choose the option to sync with Health Connect and tap Set up. If Health Connect is not installed yet, the app will offer to install it.
4. Choose the data to share and tap Allow.

Having trouble syncing?
1. Make sure the Google Health app, GymRats, and Health Connect (Android) are all updated to their latest versions.
2. Check that your Fitbit device has synced recently in the Google Health app. If a workout is missing there, it cannot reach GymRats.
3. Confirm Fitbit still has permission to write to Apple Health or Health Connect, and that GymRats still has permission to read from it. Permissions are sometimes reset after an app update.
4. Give it a few minutes. New workouts can take a little while to appear after Fitbit syncs.
5. If you previously connected Fitbit directly in GymRats, that connection stopped working on October 30, 2026. Follow the steps above to set up the new route.
