it doesn't do the rest, but i have a fitbit (blaze, i think) that tracks sleep phases ("light/restless", REM, deep) as well as sleep time and frequency of "awakenings" (or being restless enough that the fitbit thinks you're awake). does do exercise / activity tracking, can do food/water tracking, some other health stuff that mostly I don't use.
