How do I sync A300 with Flow web service?

You can transfer data from your Polar A300 through its USB connection or wirelessly via Bluetooth Smart with the Polar Flow app.

To sync data with the Flow web service through a USB cable, you need the FlowSync software. Every time you plug in your Polar A300 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 in the service. The Polar FlowSync software must be running on your computer’s taskbar (Windows) or menu bar (Mac OS X) for the automatic sync to work.

Go to, and download and install the FlowSync software before trying to sync. Then do the following:

1.    Plug your A300 to your computer either directly or with the USB cable. Make sure FlowSync software is running.

2.    The FlowSync window opens on your computer, and the syncing starts.

3.    Completed is displayed when you are done.

Every time a firmware update is available, FlowSync will notify you, and request you to install it.

If you change your settings in the Flow web service while your A300 is plugged into your computer, press the synchronize button on FlowSync to transfer to the settings to your A300.
