Even is sleep tracker Sense worked perfectly, a writer for The New York Times says he’s not sure that many people need one.
But why are you in the market for a sleep tracker? Sleep tracking is a little bit bogus. I’m a terrible sleeper, but neither the Sense nor any other sleep tracker has revealed anything particularly helpful about what was happening to me between the sheets. If you’re not sleeping well, you almost certainly know it already, and there’s a good chance you know why. At best, the tracker adds a layer of empirical precision to a situation already evident in your midafternoon yawns.
