Works As Advertised
Had no problems installing app onto watch, and no problems starting/ending sleep, and syncing to phone.
I like how it incorporates HR and also tries to guess what stage of sleep Im in.
Battery usage not much higher than when I would just wear my watch to bed. It uses around 15% usage for a 6 hour sleep.
Would definitely recommend this app!
