How to sync data from OH1 with a computer via FlowSync or with a mobile device via Flow app

Sync with Flow mobile App

  1. Sign in to Flow app with your Polar account.
  2. On OH1, press the button until the LED is switched on, and release. OH1 is now on.
  3. Your OH1 syncs with Flow app automatically if your phone is within Bluetooth range.

Your OH1 syncs with the Flow app automatically after you finish a training session if your phone is within the Bluetooth range. When your OH1 syncs with Flow app, your training data is also synced automatically via an internet connection to the Flow web service.

Make sure Polar Beat is not running on your mobile when syncing.

Sync with Flow web service via FlowSync

  1. To sync data with the Flow web service you need the FlowSync software. Go to, and download and install it before trying to sync.
  2. Place the sensor into the USB adapter with the lens facing up so that the contacts on the sensor and USB adapter meet.
  3. Plug the USB adapter into a computer USB port. Make sure FlowSync software is running.
  4. The FlowSync window opens on your computer, and the syncing starts.
  5. Completed is displayed when you are done.

Every time you plug in your OH1 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 OH1 is plugged into your computer, press the synchronize button on FlowSync to transfer to the settings to your OH1.

Make sure Polar Beat is not running on your mobile when syncing.
