Got it, checking their list of compatible apps…
Worst case you could connect to Strava as a go-between should polar be far behind on health connect (again, doubt they would be).
But checking the coospo compatibility, it seems there are a ton of them that all support health connect with coospo, so you wouldn’t be shut out even if health connect wasn’t ready for Polar, you’ll have a ton of options. Including using polar to sync to something that syncs via health connect.
Which is kind of what I do btw, aside from the app for the completely irregular use case I mentioned, I sync polar to Strava, Strava to Fit via health connect. I do that because fairly often I am using polar while cycling, so that’s how I want my data to go. But I then found strength training shares nicely too, and running polar beat and my workout app, I can track all my workout routine items (jefit), which syncs via health connect, and then polar goes to Strava goes to health connect, and it all shows as a single session with great HR data.
So yeah, you’ll be fine.
