If some time periods of data appear to be missing, please check the following.

1. Background sync policy: For battery efficiency and security, b.ring doesn’t send data in real time while the app is closed. If you’ve gone a while without opening the app, it may take time to retrieve all the missed data—please keep the app open and wait a moment.

2. Smartphone time settings: In your smartphone settings, check that [Date & Time] is set to “Automatic (use network-provided time).” If the time is set manually, data timestamps can become inconsistent and not display properly.

3. Time worn and charging status: While the ring is off your finger or sitting on the charging dock, biometric data and activity are not measured.
