  2. Your iOS software is updated to the latest version.Verify by going to Settings > General > Software Update to check for updates. 
  3. Bluetooth is enabled in iOS settings.


If your tracker is still not syncing to a supported iOS device, complete the following steps:
  1. Restart your tracker. See How do I restart my tracker? for instructions.
  2. After your tracker has restarted, reboot your iOS device and then open the Fitbit app to initiate a sync.
  3. If you're still having trouble, set up your tracker as a new device by following the instructions in Setting up Your Tracker with the Fitbit app for iOS.  Note that if you have not synced in over 24 hours, your activity data for previous days will be lost and only today’s data will remain.
