So I got my watch a few days ago and was looking froward to trying this.
I don't know if I am the only one but I was having 2 problems with "Sleep Tracker: Auto Sleep Cycle Watch Monitor" which I tried first:
- It was hitting the battery life quite a bit, even during the day (I had no other third party app installed and battery immediately and clearly improved after I deleted it, so I am pretty sure it was the problem)
- For some reason it was recording two identical sleep entries per day
So I moved on to AutoSleep, and though I don't like the IU (ugly and unclear in my opinion), it seems like a better technical solution to me at the moment and this is what I will go for.
