• Check that your watch and the Da FIt app are fully updated.
  • Turn on Bluetooth and GPS on your phone and grant the Location permission for the Da Fit app.
  • Open the Da Fit app and check to see if your watch can connect automatically.
  • If the watch can connect automatically, this issue may have occurred because the Da Fit app is prevented from running in the background. If you are using an Android phone, you need to add the Da FIt app to the protected list in the background. If you have installed third-party phone manager apps on your phone, add the Da Fit app to the white list using the apps.
  • If your watch cannot connect automatically, connect them manually. To do this, open the Da Fit app, go to Add a Device, and then Select ColorFit PRO.


If this issue persists, perform the following to troubleshoot:


  • Disable and enable Bluetooth on your phone and try again.
  • Restart your phone and reconnect the phone and the watch again.
  •  To reduce the chance that the Da Fit app is cleared from the background, Lock the App in the background.
  •  Unpair your watch from the phone using the Da FIt app and then pair them again.
  • For Android users: Open the Da Fit app, go to Devices and then select unbind and pair two devices again.
  • For iOS users: Open the Da FIt app, go to Devices and then select unbind and pair two devices again. On your phone, go to Settings > Bluetooth, touch the exclamation icon next to the Bluetooth name of the paired watch, and then touch Forget This Device to delete the pairing records for reconnection.
