Please note that the Polar FlowSync data transfer software is currently not compatible with macOS Big Sur. This means that you cannot install FlowSync or synchronize your Polar product on a Mac running Big Sur. Big Sur brings with it some major changes, which is why we need to make some significant under-the-hood adjustments to FlowSync. Before a Big Sur-compatible FlowSync version is available, you can synchronize your Polar product using the Polar Flow app on your iOS or Android mobile device.

Customers with Windows 7 and Mac OS X 10.9 - 10.11 can continue to use FlowSync 3, but we no longer provide product support.
