If you can't see any updates of your recent activity in Polar Flow app, something has gone wrong with the sync. Let's see where the problem might be.
The data is synced automatically once an hour. If the automatic sync doesn't work, please make sure that:
- Polar Flow app is running at least in the background
- your phone is within the range of 10 m/33 ft from your Polar Loop
- Bluetooth is turned on in your phone settings and working.
NOTE: Automatic sync doesn't work if several Polar Loop activity trackers are used with the same phone.
Pressing the button on your Polar Loop will start the sync if there hasn't been one in the last 15 minutes. If the sync doesn't work, please go through the following checklist first:
- Check that Bluetooth is turned on in your phone settings.
- Do not wear a heart rate sensor when attempting to sync. If a heart rate sensor is close by, remove the sensor from the strap to stop the Bluetooth signal transmission.
- If your Polar Loop is plugged into a computer with a USB cable, unplug it and wear it on your wrist to make the button work properly.
- Make sure there's enough battery both in your Polar Loop and your phone.
If you performed any of the above actions, tap the touch button on your bracelet to start the connection..
If the sync still doesn’t work:
- Turn the flight mode on and off in your Polar Loop. See User manual under Other display views.
- Remove the bracelet from your wrist. Cover the connector of the bracelet with your finger, tap the button on the bracelet and place the bracelet on your phone.
- Close the Polar Flow app and restart your phone. Then start the app again and try syncing once more.
