Use this guide if workouts pause unexpectedly, GPS distance or routes look wrong, steps are undercounted, or the band keeps disconnecting.
Update to app version 6.9.1 first. It improves GPS distance, route maps and tracking after a fast segment (like a car ride), plus average heart rate, average speed and swim pace.
If your workouts are pausing unexpectedly, GPS is inaccurate, or the device is disconnecting, your phone's battery optimisation settings are likely stopping the app in the background. Follow the steps below for your specific device.
iOS (iPhone) Settings
1. Turn off Low Power Mode — this is the most common cause of tracking issues.
- Settings → Battery → Low Power Mode → OFF
2. Enable Background App Refresh — enable this globally and for the app specifically.
- Settings → General → Background App Refresh → ON
- Settings → the app → Background App Refresh → ON
3. Set Location to "Always" — "While Using" is often not enough if you lock your screen during a workout.
- Settings → Privacy & Security → Location Services → the app → Always
4. Allow Bluetooth Access.
- Settings → Privacy & Security → Bluetooth → Enable for the app
Tip: Pro Tip: After pressing Start on your workout, wait 3–5 seconds before locking your screen or putting your phone in your pocket. This allows GPS and Bluetooth to fully stabilise.
Android Settings
Note: Android menus can vary slightly by device manufacturer (Samsung, Pixel, etc.).
1. Set Battery to "Unrestricted" — tell the phone not to stop the app to save power.
- Settings → Apps → the app → Battery → Unrestricted
- (On some devices, select "Don't optimize")
2. Disable "Put app to sleep".
- Settings → Battery & Device Care → Battery → Background usage limits → Never sleeping apps → Add → the app
3. Set Location to "Allow all the time".
- Settings → Apps → the app → Permissions → Location → Allow all the time
4. Stop Auto-Permission Removal — prevent the system from revoking settings if you haven't used the app in a while.
- Settings → Apps → the app → Permissions → Remove permissions if app is unused → OFF
- (Also labelled as "Pause app activity if unused")
5. Allow Background Data.
- Settings → Apps → the app → Mobile data & Wi-Fi → Allow background data → ON
- (Turn on "Allow unrestricted data usage" if available)
6. Allow Bluetooth / Nearby Devices.
- Settings → Apps → the app → Permissions → Nearby devices (or Bluetooth) → Allow
