Very good app!

I use it for a few days with my iWatch and it’s very nice. Easy to use and seems to collect all data as it should be. I would give it one more start if
a) it had some more data to correlate with sleeping cycles. Hearth rate is available from iWatch and combining these two metrics would give some more information, now I need to use another app to check hearth rate during sleep.
b) it would report in-bed and asleep phases correctly to iWatch Health app

I would even pay for $1-2 for this app if it would do above.
