Apple watch activity detection is kinda crap. - Sleep detection sort of works for going to bed, but doesn't recognize a lie in after sleepily hitting the button and dozing off for another hour. It also doesn't recognize being awake in the night, unless I actively get up. - It detects maybe half of the walks I go on, and usually well after I've already triggered cyclemeter. (So, there's a simple heuristic that I'm on a walk -- I've told it so) - It interprets the cat headbutting my wrist as a cue to change the watch face.
