My smartwatch doesn't sync — how to fix it and resetUpdated a month ago
🔄 Step 1 — Quick sync fixes
If your data isn't syncing between the watch and the app, start with these quick checks:
- Make sure Bluetooth is enabled on your phone and the watch is connected.
- Open the ICE Smart app and check that the watch appears as "Connected".
- Pull down to refresh data in the app, or close and reopen the app completely.
- Keep the app open in the background — this helps maintain automatic sync.
💡 On Android: go to Settings → Battery → ICE Smart → disable battery optimisation. This is the most common cause of sync issues on Android.
🔁 Step 2 — Full reset procedure (if sync issues persist)
If the quick fixes above didn't help, a full reset and re-pair will resolve most sync problems.
- Open the ICE Smart (or ICE JUNIOR) app → go to device settings → remove the watch from the app.
- On your phone, go to Bluetooth settings → find the watch → tap "Forget this device".
- On the watch, go to Settings → Factory Reset and confirm.
- Once the watch has restarted, open the app and re-pair by following the on-screen instructions.
⚠️ A factory reset erases all local data on the watch (activity history, watch faces, settings). Health data already synced to the app is preserved.
⚙️ When to perform a factory reset
A factory reset is the recommended solution for:
- Persistent sync or connection issues
- The watch freezing or behaving unexpectedly
- Preparing the watch for a new user or new phone
- After a failed firmware update
