If you’re out of Bluetooth range or don’t have cellular/Wi-Fi, your ring will continue to track your biometric data. It stores everything locally and syncs once it reconnects.
Pro tip: If you want to record a session while you’re out of service, start it before you lose connection—or log the session later in the app.
Once you’re back in Bluetooth range (or back online), your ring will automatically sync all recorded data to the app—no data is lost.
Note: Syncing may take a little longer than usual if it’s been a while since your last sync.
