If anyone wants a tool to show you this analysis automatically, I make an app that links with Whoop and Oura and Apple Health and it shows you all of those relationships: https://apps.apple.com/us/app/reflect-track-anything/id64638...
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?
Why did the author not evaluate the sleep tracking that comes with the Apple Watch out of the box?
Nice article but I with there was something more authoritative to compare it to. I know controlled in-lab sleep studies are expensive but this would be the key data to have in the mix.
Really surprised that Autosleep performed so poorly. I've been using it for over a year and I'm pretty satisfied, and chose it because it was the only apple watch sleep app I could find that didn't require a monthly subscription. Admittedly I don't look at the 'score' so perhaps that's it, I just look at the overall 'quality sleep' hours and have found that tracks pretty well with how off-my-game I am that day.
I enjoy Peter Norvig's writing style—it's rich in detail and backed by solid statistics. I've also been following Andrej Karpathy for the past two years, and I have to say, his writing has become my top priority to read first.
My Garmin Instinct Crossover watch does a great job of sleep tracking. It correlates well with how I feel the next day and how active I was the day before. On the other hand, Sleep as Android inflates the scores too much to be useful.
I have a (LONG discontinued) zeo, but stopped using it after I ran out of the contact patch things. Too bad, it was a true EEG sleep tracker.
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.
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
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.
