It does exactly what is says it does. With a Polar H10, displays the HR in BPM with a one-second refresh rate. I would give it 5 stars if there was a way to store/export the data.
Doesn't connect to Polar H10 (which is working fine with Strava.) Not shown on available device list.
I have multiple devices none of them have connected, useless.
Didn't work at all
Does what it's supposed to do. Put Polar on, turn on BT, pair, start app, choose BT device and observe heart rate.
Doesn't work on M600
