FAQ

Why does my Fitbit take forever to sync?

Long syncs happen when there’s a lot of data to transfer or weak Bluetooth connection. Move closer to phone, ensure Bluetooth isn’t being used by other devices, and wait for sync to complete without closing the app.

Why does my Fitbit only sync sometimes?

Intermittent syncing usually means Bluetooth interference or battery saving features killing the app. Disable battery optimization for the Fitbit app and keep Bluetooth enabled at all times.

How often should Fitbit sync automatically?

Fitbit should sync automatically throughout the day when All-Day Sync is enabled. It syncs when the app is opened and periodically in the background. Enable All-Day Sync in app settings for best results.
