Syncing data between Vantage M/Vantage V
and Polar Flow app fails
If your Polar Vantage M or Vantage V 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 Vantage M/Vantage V 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 Vantage
M/Vantage V, 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:
