I was looking for AndroidWear sports apps for the Polar M600. I found a few and some were even interesting! Although there was not too much to tempt me away from the POLAR app that is inbuilt into the M600.
Then I stumbled across swim.com (ios and android and other platforms) and the chart to the right, from that app’s site, seems to suggest that the app will effectively add LOTS of swim-functionality onto the M600. Indeed onto many devices (other devices not shown).
It’s on my watch but I’m yet to use it.
Anyone had a go with it? does it store HR?
edit: bug on polar M600 !!! 24/1/17 since dec 2016.
