Quick fix
Reconnect your watch in the correct order
1. Remove the stale pairing
Open the phone Bluetooth settings. If the watch appears under paired or saved devices, choose Forget, Unpair, or Remove. If Da Fit still shows the old watch, open its Device page and choose Remove Device.
2. Restart the connection
- Turn phone Bluetooth off, wait a few seconds, and turn it on again.
- Restart the smartwatch.
- Keep the watch awake and within one meter of the phone.
- Temporarily disconnect other nearby phones that previously used the watch.
3. Pair from inside Da Fit
- Open Da Fit and allow Bluetooth or Nearby Devices permission.
- Open the Device tab and tap Add Device.
- Select the watch from the scan results.
- Accept the pairing request on the phone and watch when prompted.
- Keep Da Fit open until the first data sync finishes.
If it still fails
Check permissions, ownership, and distance
Da Fit cannot find the watch
Confirm that Bluetooth is enabled and the watch is not already connected to another phone. Android users should allow Nearby Devices and location access if the system requests it. Move away from other active watches during scanning.
The watch connects, then disconnects
Phone battery management may close Da Fit after the screen turns off. Allow background activity, disable battery optimization for Da Fit, and lock the app in the recent-apps screen when that option is available. See the Da Fit background permission guide.
iPhone pairing prompt does not appear
Check Settings > Privacy & Security > Bluetooth and allow Da Fit. Remove the old watch from Settings > Bluetooth, reopen Da Fit, and start the connection again from Add Device.
