Just curious what benefit do you get from sleep tracking? I had sleep problems for a while. I wasn't really sure how helpful it would be for an app to tell me I had a crappy night's sleep! Is there more to it than that?
It's evidence to show people (family, doctors, etc... and yourself). It's harder evidence than flaky human memory or "impressions" of how I slept, in any event. You can literally see how crappy your sleep is, on a chart. It's rather eye-opening, and if you have a wife or girlfriend who wonders why you're a space cadet today who can't get anything done, you can always point to the "4 hours of good shuteye" chart from last night (if it exists) lol
Interesting, I guess it is always surprising when you actually log stuff as opposed to just going by memory.
