Nope.
I kind of know how well I have slept without reading data in the morning. This might be good for people who have sleep issues, but I can’t see the use of it for those who don’t.
It’s really amazing how the human race has survived as long as it has without this stuff.
I have a friend that I travel with. She can’t keep her hands off her Fitbit. She’s constantly touching it to see how many hours she slept, what her heart rate is, how many steps she’s taken. I said....who cares?!?!
