You are here: Polar Flow > Syncing


You can transfer data from your Verity Sense to the Polar Flow app wirelessly via the Bluetooth connection. Or, you can sync your Verity Sense with the Polar Flow web service by using a USB port and the FlowSync software. To be able to sync data between your Verity Sense and the Flow app you need to have a Polar account. If you want to sync data from your Verity Sense directly to the web service, in addition to a Polar account, you need the FlowSync software. If you've set up your Verity Sense, you have created a Polar account. If you set up your Verity Sense using a computer, you have the FlowSync software on your computer.

Remember to sync and keep your data up-to-date between your Verity Sense, the web service and the mobile app wherever you are.

Sync with the Flow mobile App

Before syncing make sure:

  • You have a Polar account and the Flow app.
  • Your mobile device has Bluetooth turned on, and airplane mode/flight mode is not turned on.
  • You have paired your sensor with your mobile. For more information, see Pairing.

Sync your data:

  1. Sign in to the Flow app with your Polar account.
  2. Turn the sensor on by pressing the button.

The sensor automatically syncs with the Flow app when you stop recording a training session if your phone is within Bluetooth range. If your phone has an internet connection, your training data is also synced automatically to the Flow web service.

Sync with Flow web service via FlowSync

To sync data with the Flow web service you need the FlowSync software. Go to, and download and install it before trying to sync.

  1. Place the sensor into the USB adapter with the lens facing up so that the contacts on the sensor and USB adapter meet.
  2. Plug the USB adapter into a computer USB port. Make sure FlowSync software is running.

  3. The FlowSync window opens on your computer, and the syncing starts.
  4. Completed is displayed when you are done.

Every time you plug in your Verity Sense to your computer, the Polar FlowSync software will transfer your data to the Polar Flow web service and sync any settings you may have changed. If the syncing does not automatically start, start FlowSync from the desktop icon (Windows) or from the applications folder (Mac OS X). Every time a firmware update is available, FlowSync will notify you, and request you to install it.

If you change settings in the Flow web service while your sensor is plugged into your computer, press the synchronize button on FlowSync to transfer to the settings to your sensor.
