CEO Tests Oura, Apple Watch, Fitbit And Whoop On Eight Sleep Mattress

Results are back + screenshots in thread. Here's my ranking of top sleep trackers based on last night's reporting: 1. Oura 2. Whoop 3. Eight Sleep 4. Apple Watch 5. Fitbit Air

Tracking workouts and steps data today across Oura, Whoop, and Fitbit and will report back

First - Oura: * Accurately picked up my wake up times (4 week old has me up at night) * Accurate sleep start time * Total sleep seems the most accurate * RHR + HRV seems most accurate * Readiness score of 85 is aligned with how I feel today

Fourth - Apple Watch: * Way overshooting my sleep score * Accurate wake ups and sleep time * HRV is at 57 (had to go find it in the Health Data list) and honestly I have no idea how these are measured now * No readiness score! * For how bulky it is to sleep with at night I would not recommend

Last - Fitbit Air * Bug in the sleep tab, cannot see sleep score unless I tap * Gave me an 86, way overshot * Sleep tracking is a mess. I was awake a few times in the night but it tracked as "restlessness" * AI coaching useless/annoying * Readiness of 75 is the first somewhat accurate readiness score in the last week, although I think not accurate still * HRV of 48 (??) - have to tap in to see the actual number

Third - Eight Sleep: * Honestly I love the bed but the sleep metrics are not as accurate as Oura or Whoop * Sleep score feels a bit high * HRV and RHR look accurate * Picked up interruptions but not as closely as Oura/Whoop

Second - Whoop: * 81 sleep score, pretty close to Oura * Picked up the same wake up times * HRV and RHR coming in higher than Oura but reasonable since worn on wrist versus finger * 74% recovery feels slightly lower than what I'd expect * I like that it tracks snoring and adjusts

I probably will not do this again. Interesting data but incredibly uncomfortable to wear 3 bands to bed!

@anothercohen FWIW there are a few different methods to calculate HRV, (RMSSD and SDNN)

as far as i can tell, apple uses SDNN, the rest use RMSSD

rmssd is measured beat after beast, sdnn is over a whole period (my explanation as an idiot)

@anothercohen not gonna lie you looked pretty ridiculous wearing 3 trackers this morning at coffee 😂

@ext87 Whoop has been like 4 days, but i had some previous data. Fitbit Air is a week. Apple Watch is the only one I never wear to bed

@heysamir_ Yes

@anothercohen Sounds super uncomfortable. How do you just the discomfort of wearing all those isn’t messing up your sleep? I find it weird sleeping eith just an Apple Watch

@anothercohen Don't these need more than one day to calibrate?

@anothercohen Not possible to use apple watch for sleep long term with such shite battery tho ?

@anothercohen Was this with Oura 5 or 4?

@anothercohen I have the Watch ultra 3, but I’ve been considering the whoop or maybe full time android with the Fitbit. The garmin seems to also do good. So many options and the inconsistency is what kills me

@anothercohen Just after lighting a cig to relax?

@anothercohen Have you tried any of Garmin watches ?

@anothercohen I’m still cautiously bullish on Fitbit Air. They fixed a couple of annoying bugs in the last update and your calibration period is still on I think.
