FlowSync software is offered by Polar as an alternative for those who would prefer to synchronize their fitness tracker's data to their web-based account instead of a mobile device. This is a manual synchronization process, meaning your device MUST be physically connected to a computer in order to perform a synchronization of your data. If you would prefer more of an automated process, please consider using the Polar Flow app on a mobile device.
