I notices that my wake periods were quite obvious in the movement patterns, yet the tracking should be as sleeping.
It would be great to give feedback when I was awake (I looked at my watch) for the algorithms to learn from that.
In general I found that if my movement pattern is about the 50% mark that is a 90% indicator I woke up at night. Yet the app doesn't seem to recognize that. So setting a threshold on the website for awake would be great as well.
