My sleep tracker said I got 7 hours and I felt like a zombie, so I did a dumb test on myself
Wore the ring every night for two weeks and it kept telling me my sleep was "good" even on mornings when I could barely string a sentence together. So one Tuesday I wrote down how I actually felt each morning on a scale of 1 to 10 and compared it to the app, and they only matched about half the time. Anyone else find that those sleep scores basically mean nothing compared to just how you feel when you wake up?
