Tried the new version last night and it only recorded the heartbeat in the health app, the hours of sleep were not recorded in the health app. There are no graphs or history or anything really to see or that is recorded in either the Sleepisle phone or watch app. I thought it would keep a record inside the app of every night and that you could graph heartbeat, rem stages, but nothing. It also wrongly recorded in my activity app something like 400% of calories and exercise while I was sleeping so it ruined my records. I slept around 8 hours and the watch was at 100% battery and in the morning I only had 14% left. Not recommended, look for other apps!
