I just dont get it.Sleep tracker? Dont you just know?, about something as personal and intimate as your own state of restedness?,energy levels? And quite honestly I worry about the cost of optimising ones life and managing everything for what?, a better performance review?, and does this kind of minute management and reliance on external sensors and data, leave a person able to make criticl descisions when facing anything outside of a habitual and specialised routine. Perhaps these could work as training and awareness devices?, which could be revealing, but I think habitual use is only going to work, for the most dedicated ...military precision types.... but for them, it will be competitive, and it's bad news for anyone outside of that group, to compete with them. And as a reminder, there is nothing quite so luxurious as well earned sleepyness, and the general feelings of well bieng and satiation that creates this, vs an off switch.
