Syncing data between Grit X/Pacer/Vantage and Polar Flow app fails

If your Polar Grit X/Grit X Pro/Pacer/Pacer Pro/Vantage M/Vantage M2/Vantage V/Vantage V2/Vantage V3 fails to sync with the Polar Flow app, please go through the following checklist first:

iOS:

  • Make sure the app and watch are both up to date: Check from the App store that you’ve got the latest version of the app installed. Flow app or FlowSync will tell you if there’s a firmware update available for your watch.
  • Make sure that Bluetooth is turned on in your phone settings.
  • Make sure Flow app is running on your phone and keep it at the foreground.

Android:

  • Make sure the app and watch are both up to date: Check from Google Play that you’ve got the latest version of the app installed. Flow app or FlowSync will tell you if there’s a firmware update available for your watch.
  • Make sure that Bluetooth is turned on in your phone settings.
  • Make sure location is enabled for Polar Flow app in the phone's application settings. On Android 6 and newer devices, location permission is needed to scan for Bluetooth devices.
  • Make sure Flow app is running on your phone and keep it at the foreground.
  • If you have several Flow app compatible Polar devices in use, make sure you have chosen Grit X/Grit X Pro/Vantage M/Vantage M2/Vantage V/Vantage V2/Vantage V3 as the active device in the Flow app. This way Flow app knows to connect to your watch. In the Flow app, go to Devices and choose Grit X/Grit X Pro/Vantage M/Vantage M2/Vantage V/Vantage V2/Vantage V3, and then return to the main menu.

If you have completed all of the above steps but you are still having problems with the sync, please choose an option below (iOs or Android) to continue troubleshooting:

Try the following steps one at a time to fix the syncing problem. Try to sync again after each step. Continue with the steps if the sync fails.

  1. Switch Bluetooth off and on from your phone.
  2. Restart your phone and your watch. To restart your watch, go to Settings > General settings > About your watch > Restart your watch. Press the OK button and then press OK again to confirm the restart. You can also restart your watch by pressing and holding the OK button for 10 seconds.
  3. Unpair your watch with the phone, and pair it again:
    1. On your phone remove your watch from the list of paired Bluetooth devices as follows:
      Go to Settings > Bluetooth, tap the “i” icon to the right of your watch and choose Forget this Device.
    2. On your watch go to Settings > General settings > Pair and sync > Paired devices. Choose your phone. Remove pairing? is displayed. Confirm by pressing OK.
    3. Pair your watch again with the Flow app. NOTE: Do NOT use your phone’s Bluetooth menu to pair the watch.
  4. Turn Flight mode on and off in your watch: Settings > General settings > Flight mode.
  5. Re-install Polar Flow app on your phone:
    1. On your phone, go to Settings > Bluetooth and make sure Bluetooth is set ON. Remove your watch from the list of paired Bluetooth devices. NOTE!

  7. Perform a factory reset to your watch. On your phone, check the list of paired Bluetooth devices and remove your watch from the list if it's there. Then, set up your watch again.
