I couldn’t find any when I looked around a couple of years ago. Anything these days? And if none are floating on the market, are there any decent wrist watches that respect your privacy and don’t send all the dam data home?

    It’s definitely not perfect, like I can grab a nap and not have it notice sometimes so I assume there are a bunch of heuristics at play that create a “best guess”.

    That said, how rested I feel does typically line up with the number of hours it shows (regardless of how long I’ve actually spent in bed), and it has a short description about the quality of sleep like “restorative” or “not enough rem” that further lines up with how I feel.
