Frequently asked questions
The band will not connect
- Make sure Bluetooth is on and the band is charged and near the phone.
- Disconnect the band from the manufacturer’s own app — many devices allow only one active connection.
- Go to Profile → Devices and start the search again.
- If the device was paired before, remove it in the system Bluetooth settings and pair again.
Data is missing or out of date
- Open the app and pull the home screen down — this triggers a sync.
- Bands keep only a limited history, so sync at least every few days.
- Check that the app has permission for the required Apple Health categories.
- Today’s metrics keep filling in during the day; final values settle after a night’s sleep.
Why do energy and recovery change during the day
Recovery is calculated from night-time data: heart rate variability, resting heart rate and sleep quality. If your band uploads night measurements later in the morning or afternoon, the value is recalculated — this is expected.
Notifications do not arrive
Check that notifications are allowed in your phone settings and that Do Not Disturb or battery saving is not blocking the app.
