FlowSync
FlowSync is Polar's fitness data management and device synchronization app for macOS. It syncs data from Polar sports watches, fitness trackers and cycling computers to Polar's cloud service, Flow. The app displays workout summaries, training load analysis, heart-rate trends, and recovery metrics, and lets users configure device settings, upload data to third-party training platforms, and export activity files. It is essential for any Polar device owner who wants to review and track their training and health data on their Mac.

1 suggestionFlowSync version 4 is the current release and is confirmed compatible with Apple Silicon Macs, but according to Polar's own support documentation, it still runs under Rosetta 2 emulation rather than as a native Apple Silicon build. Polar has not released a native arm64 version of FlowSync. The app will continue to work under Rosetta 2 until Apple removes the emulator in macOS 28 (September 2028), at which point an Intel-only build will cease to launch. Contact Polar Support at support.polar.com to ask about plans for a native Apple Silicon build before the Rosetta 2 sunset; their response will determine whether you should expect an upgrade in the next two years or begin planning a transition to an alternative fitness tracking app. In the meantime, FlowSync 4 remains usable on your M-series Mac, though it will consume more battery and CPU than a native build would.
