Syncing data between Polar Verity Sense and Polar Flow app fails

If your Polar Verity Sense fails to sync with the Polar Flow app, please go through the following checklist first:

iOS:

  • Make sure the app and sensor 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 sensor.
  • 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 sensor 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 sensor.
  • 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 Verity Sense as the active device in the Flow app. By doing this the Flow app will connect with your sensor when pairing. In the Flow app, go to Devices and choose Polar Verity Sense, 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, 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.
  3. Unpair your sensor with the phone, and pair it again:
    1. On your phone remove your sensor from the list of paired Bluetooth devices as follows:
      iOS: Go to Settings > Bluetooth, tap the “i” icon to the right of your sensor and choose Forget this Device.
      Android: Go to Settings > Bluetooth, choose your sensor and Forget this Device.
    2. Pair your sensor again with the Flow app. NOTE: Do NOT use your phone’s Bluetooth menu to pair the sensor.
  4. 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 Verity Sense from the list of paired Bluetooth devices. NOTE! This step is important, especially with iOS devices since new device pairing can't be done in the Flow app before the earlier connection has been removed from the Bluetooth device list.
    2. Turn off Bluetooth on your phone.
    3. Sign out from the Flow app and uninstall it from your phone.
    4. Restart your phone.
    5. Turn Bluetooth back on in your phone.
    6. Install Flow app again from the App store and sign in with your Flow account.
    7. Pair your sensor again with the Flow app. NOTE: Do NOT use your phone’s Bluetooth menu to pair the sensor.
  5. If the connection still doesn't work, sync your sensor with FlowSync. If you're prompted to update your Verity Sense firmware, accept the firmware update.
  6. Perform a factory reset to your sensor. On your phone, check the list of paired Bluetooth devices and remove your sensor from the list if it's there. Then, set up your sensor again.

If your training data won't sync from the sensor to the Polar Flow app, make sure you have signed in with the correct email address. If this is the case, please follow the troubleshooting steps above.
