Unlike the frustrating iOS situation, Fitbit syncs natively to Google Health Connect on Android — no third-party apps required. Since Google owns both Fitbit and Health Connect, the integration is built directly into the Fitbit app. Google’s support documentation confirms the setup is straightforward. If you use a Fitbit Sense, Versa, Charge, Inspire, or Luxe with an Android phone, here’s how to get your data flowing.
How Do You Connect Fitbit to Health Connect?
The setup lives inside the Fitbit app. You’ll need a Google Account (legacy Fitbit accounts were migrated to Google accounts in 2025).
Step 1: Open the Fitbit app on your Android phone. Tap the Settings gear icon in the top corner.
Step 2: Scroll to find Health Connect and tap it.
Step 3: Toggle Sync with Health Connect to ON. Tap TURN ON when prompted.
Step 4: The Health Connect permissions screen appears. Select which data categories to share — or tap Allow All for the most complete integration. Then tap Allow and Done.
Step 5: Sync begins automatically. Data from your Fitbit flows to Health Connect each time the Fitbit app refreshes data from your tracker.
Account requirement: You must be logged into the Fitbit app with a Google Account, not legacy Fitbit credentials. If you haven’t migrated yet, the app will prompt you — and the deadline for migration was February 2026, after which unmigrated accounts risk data deletion.
What Fitbit Data Syncs to Health Connect?
The native integration transfers a solid core set: steps, heart rate, resting heart rate, sleep sessions with full stage breakdowns (REM, Deep, Light, Wake), workout sessions with heart rate and calories, distance, elevation gained, floors climbed, and total calories burned.
Data that does NOT sync to Health Connect: HRV, SpO² (blood oxygen), skin temperature, breathing rate, stress management score, Active Zone Minutes, Daily Readiness Score, ECG recordings, and Fitbit’s coaching recommendations.
The HRV gap is the most significant for ScoreVitals users. Fitbit tracks HRV (using RMSSD) but doesn’t expose it through Health Connect. The recovery pillar will rely on resting heart rate trends instead. Workout heart rate data does transfer reliably, which means TRIMP-based session scoring and ACWR monitoring work well. Sleep stage data is strong, feeding the sleep pillar accurately.
How Do You Fix Fitbit Health Connect Sync Issues?
Ensure your phone meets the requirements. Health Connect requires Android 14 or later for built-in support. On Android 13, install the standalone Health Connect app from the Play Store first.
Check that permissions are still active. Go to your phone’s Settings → Security and Privacy → Health Connect → App Permissions → Fitbit. Confirm all categories show “Allowed.” Android updates can sometimes reset permissions silently.
Force a fresh sync. Open the Fitbit app and pull down on the main screen to trigger a manual sync with your Fitbit device. This also pushes data to Health Connect. If specific days are missing, this usually resolves it.
Battery optimisation matters. Set the Fitbit app to Unrestricted battery usage in Settings → Battery → App Battery Management. Restricted background activity prevents the Fitbit app from writing to Health Connect in the background.
Restart after permission changes. If you modify Health Connect permissions in the Android Settings app, open the Fitbit app afterward for the changes to take effect.
Clear cache if sync is completely stuck. Go to Settings → Apps → Fitbit → Storage → Clear Cache (not Clear Data — that would log you out). Then open the Fitbit app, wait for it to sync with your device, and check Health Connect.
Fitbit delivers a clean, native Health Connect integration on Android. Once connected, ScoreVitals can use your Fitbit workout and sleep data to calculate daily readiness scores automatically.
