I'm looking for a wearable, preferred a wristband, to track my sleep cycles and wake me up (silently) at the best time according to what it tracks about me.
If it has other features, such as activity/fitness tracking - cool, but that it won't be a must to wear it all day.
Side/on bad trackers won't be very useful for me, since I live with my girlfriend and so we sleep together in the same bad. So it shouldn't be distracted by other people in the room.
I checked this question, but it's a year and a half old, so maybe there are new things on the market that I'm not aware of.
Any recommendations, or jawbone is still the best and maybe the only choice for that? How about the Mi Band? Thanks!
