I use polar H10. Very happy with it together with bangle.
It additionally can provide real ECG Data, HRV, Accelerometer.
There is already a bangle App for HRV.
Not yet for ECG and ACC, but that would be not very difficult.
So far I record this with an non-cloud Android app (the original polar is cloud only)
The H10 is able to send Bluetooth to 2 receivers at the same time (eg bangle and phone or workout machines) but I didn't use this so far because its difficult to activate without polar cloud.
