My old Fitbit just gave me a sleep score number with zero explanation. The new AI breakdowns feel like they're making up problems to solve. We slept fine for years without all this data.
Manual sleep logs from a decade ago, yeah that hits home. I used a notebook by my bed, scribbling times when I woke up. It was messy but you learned your own patterns after a while. Now apps do all the guessing for you. Kind of miss figuring it out myself sometimes.
