My fit bit monitors my sleep. I don't wear it every night to bed, but I know that I'm a terrible, terrible sleeper.
These are the stats the Fitbit has given me month on month, and you can see recently, my sleep has been awful in terms of hours slept!
If I click on a given day, it goes a little deeper.
It shows me how well I slept overall.
I'm a terrible sleeper. Nothing helps!
