+> After 10 years, Polar has begun _sunsetting_ the FlowSync (desktop) application,
+> and requires the Flow (Android and iOS) app instead for full data sync. From the

+> >
+> > The following data cannot be synced using the Polar FlowSync software on your
+> > computer: skin temperature, wrist ECG and SpO2 (blood oxygen saturation). We
+> > recommend syncing with Flow app as **we're gradually sunsetting FlowSync**.
+> > FlowSync doesn't support all the features on your watch, which means that some
+> > of the data won't be synced. If you continue with FlowSync anyways, you can sync

+> As such, I no longer intend to continue any development on this Bipolar project.
