I'd love to see this comparison between Garmin and Oura. I ditched Whoop because it was too easy to get 100 sleep scores, but my Garmin watch is much harder to please. I do think it offers better signal, but I've never scored over a 90, so maybe it is too critical?

I like garmin, and have to keep working to get a good sleep score.

that said, when I do get very good or very poor sleep, the score reflects it.

Native Apple Watch wins in most scientific papers and also in tests done by “the quantified scientist” by a large margin. Apple Watch does not use HRV but accelerometer for movement and breathing rate.

Apple Watch also wins for HR during exercise.

So if you want one device for everything, there is little competition yet.

I just dont get it.Sleep tracker? Dont you just know?, about something as personal and intimate as your own state of restedness?,energy levels? And quite honestly I worry about the cost of optimising ones life and managing everything for what?, a better performance review?, and does this kind of minute management and reliance on external sensors and data, leave a person able to make criticl descisions when facing anything outside of a habitual and specialised routine. Perhaps these could work as training and awareness devices?, which could be revealing, but I think habitual use is only going to work, for the most dedicated ...military precision types.... but for them, it will be competitive, and it's bad news for anyone outside of that group, to compete with them. And as a reminder, there is nothing quite so luxurious as well earned sleepyness, and the general feelings of well bieng and satiation that creates this, vs an off switch.

I've found Garmin's sleep tracking to be unreliable. For instance, if I lie in bed reading before I fall asleep, it often incorrectly logs that time as sleep.

I had over 90 scores, and only when I get earlier in bed and if there are medications involved. you do feel like you had a great sleep so for me it's very accurate.

Sorry, but I think this guy (The Quantified Scientist) has the article beat in terms of rigor and analysis (As some other peoole mention) https://www.youtube.com/watch?v=kCVf3QPm-8w

- Similar graphs

- Medical grade baselines

- His whole channel is dedicated to this kind of stuff

- The original post is good, its just this channel is insanely good
