Hello, any plans to do a review of a Somnofy unit to test it’s (unique ?) sleep tracking technology ? Thank you for your work, super useful really enjoying it
I was a bit disappointed, it seems like this is a very mediocre device yet your review went pretty easy on it, and i felt like it was because you had a promotional link. Being harsh, we have waited a long time for a whoop upgrade due to unreliability and inconsistency, yet this doesn't perform as well as its predecessor. I value your data so much and actually looked for an email so not to make this public, you provide such a great value
In your other videos you've put the Whoop 4.0 as one of the very best performing (top right quadrant) sleep trackers you have tested, far beyond anything from other brands apart from FitBit or Withings. In this test, it doesn't perform nearly as well. Can you provide an updated view showing more data over a longer period that reconciles its overall performance based on having used it for a longer period. Otherwise your videos are inconsistent.
Make a playlist of the watches which are atleast 95% accurate according to you.. It will be really helpful.... And i Love your videoss 😇
That playlist will be created probably after 2030. At the moment, the best of bests are around 75-80%
Apple watch 7, Sensor elevator 4.0 of garmin. The most problem is if you do crossfit, weightlifting or some like that
@@francobellomo9979 hello, I need an accurate heart rate smart watch or band
,I do walking on treadmill and light body building kind of ,can you recommend something, I'm clueless
@@mopedblade Polar h10 is the best chest trap, you can use with a watch sport or with smartphone (start a session on Polar Beat and go to training, next sync with smartphone).
@@francobellomo9979 thanks but I'd prefer something like a watch or band , I bought the mi 6 a week ago but I think the accuracy is wack
The best and most useful proper reviews of these devices, as far as I know.
Great review as always! Love this deep dive method! Also really happy to see so much content being pushed out especially because you keep the quality of it absolutely top notch!!!!
Commenting just for the algorithm, I really enjoy the unique information you provide, great stuff!
Thanks for your well made videos. Straight to the point with meaningful numbers. Keep up the good work. I am glad you covered the whoops 4.
Thank you very much for your excellent tests!!
great review! as always! waited so long for a channel like yours!
I’ve been waiting for WHOOP 4 video 😍😍
Dude, you're killing it with your scientific reviews! Keep it up !!!
From release till now I’ve only waited to see you review it before considering if I’d purchase it!!
So glad to see this review finally be release!! 😁
Great work as always!!
Glad I could help!
Another fantastic video, I really hope your channel grows
Thanks for this review. Looking forward to a review video on Oura 3.
This content is freaking amazing!
Well done. I hope whoop is taking notice
Will there be a follow-up? It has been a few months, I'm wondering if they improved it since then?
Hi, Im still waiting for your update review😆
Great video, and thanks for the big effort! Are you planning on a review of the biostrap.
Thanks!
A scientific review of the CORE body temperature sensor would be cool!
Good review as always. Please do Ticwatch Pro Ultra when possible. 👍
Currently waiting for Amazfit bip U pro since it is presented there and also quite good performance based on the graph.
I really appreciate your approach on evaluating the systems. But I can’t get over how you only took a sample size of 2 nights.
And yes I get it your findings show that there are cases in which HR is not correctly read and therefore sleep states are off. Thats fine. The only problem I see is putting it on a contingency table and stating that these are representative percentiles for measurement errors. You would need a much higher sample for this to be significant imo.
I would love to hear your take on this and again I really appreciate your videos.
Well done, very informative! I've noticed you shortened your intro. Although I miss the cool music I like the intro being a bit shorter :-)
Like many others I’m waiting for my 4.0. Hopefully there will be some firmware updates released before it arrives that fix some of the accuracy issues. Maybe a follow up video in a few months will be warranted to see if things improve.
Hey James, your comment is now 7 month old, I think about buying a whoop 4. Did you notice firmware updates for the addressed heart rate accuracy?
@@Mediaroo1 Hi Tim. I've actually been very pleased with my 4.0. It's more in line with my Apple Watch, and if you watch more of his video's you'll see the Apple Watch is one of the most accurate trackers out.
@@jameshuegli3534 thank you! Did you make real improvements for your body and/or wellbeing based on the whoop data or is it more nice to know? Thank you for your time!
@@Mediaroo1 Hi Tim. I think the Whoop data is super valuable. Case in point - this Sunday I woke up and under the "health" section it said my RHR was 63 when it's usually 57-58 (no more than 60). Guess what? I felt achy all through the morning and at around 11 AM I took my temperature and I had a fever of 100. That's just one example - the stats always let me know when I have a cold/illness coming on. I really am working hard on getting my HRV up. It's hard when you have a 2 year old and a lot going on in life, but it's my goal to get up into the 40s. Anyways, I really love my whoop.
@@jameshuegli3534 thank you for your time and the answer! :)
Thank you for your amazing Channel! Would you recommend the oura Ring or the whoop Strap for Sleep and Recovery? I guess from your videos, the oura ring is more accurate for HRV from your measurements?
thanks
we need an update to Oura 3, a real one this time
Would love to see a new video now the 4.0 has been out for over a year. Really interesting video
Hello,
Thanks for your videos. Still it is hard for me to compare major available sleep monitoring devices. Do you have a video comparing the main available sleep tracking options in the market?
Thanks
Disappointed to see that v4 didn’t improve over v3 despite claims by the manufacturing firm. I was willing to buy it but I need to reconsider my decision.
Thanks for sharing. Is there anything out there today that accurately measures the calories in and out automatically? That would be the most important measurement for me. Cheers
Would love to see an update on whoops sleep accuracy
Great video, What’s the best for sleep tracking the Wrist or biceps?
The subscription cost is what keeps me away from whoop. It’s not very expensive, but having to pay monthly or the strap is useless is kind of ridiculous. Pay once for an Apple Watch and it works forever (or until apple slows it down)
I really thought this would finally convince me to get Whoop, but the results are quite dissapointing.
Yeah it's a hard pass from me. But thanks to these videos I'm not wasting my money so I'm stoked there people like this creating these reviews.
What about analysing a Garmin Fenix 6? I misses It on your videos. Thanks you in advance
Hi Quantified Scientist, great work on these tests!
I have a question about the SP02 monitoring: Do you know if the sp02 monitoring is sensitive enough to detect changes if someone was to be in a hypoxic or even an inverse state of hyperoxia?
*as in early detection of oxygen toxicity.
Sounds like a other beta hardware released that's inferior to the previous generation. Yup they will improve but I would love you analyse how easy it is to replace a battery. Should we buy s new gadget every year just because there's a new version of it?
Been using oura 2 for 3 years and it's dead. No way of replacing battery, oura will give you a mere discount so you can buy new one. Sad to see gadgets promoting themselves as helping us being better version of themselves have a business model not focus on sustainability but rather well growth for investors.
Hi, is there an update on new heartrate results for the whoop 4? thank you!
Rooooob please do the tic watch pro 3❤️
I definitely am bit disappointed with these results please do keep us updated I will stick with my 3.0 and getting a Apple watch on your recommendations
Why do you have the Whoop4 ranked below the Fitbit Charge5, FitbitInspire2, and FitbitSense on this chart but every other chart you have the Whoop4 beating them? This is extremely confusing.
Please let us know if the firmware updates to the whoop 4.0 increased its hr accuracy or is it still the same as in this review
Sleep tracking better on wrist or bicep?
Which one is all round best for heart rate during training,sleep activity and hrv ?
Whoop
Polar
Garmin
Morpheus
Or
Maybe some other ?
Can you review the Amazon Halo
I know it's old but do you have any test data of an fitbit versa 2? Or do you have a fitbit versa 2?, I want to know how accurate the sleep is on that device, as I know that hr wouldn't be the best at all
When are you getting the new oura ring?
Finally
Liked and comment for tje algorithm
Thanks!
Hi, bist du auch Österreicher? Ich bin irgendwie auf deine Videos gekommen, weil ich gerade die richtige Garmin Uhr suche. Ich bin zwar mit dem Oura Ring was den Schlaf angeht abgedeckt, jedoch bin ich mir nicht so sicher, wie es nun weiter geht. Damit meine ich, soll ich den neuen Oura Ring mir besorgen, oder doch eine Uhr? Was meinst du dazu? Ich bin sehr sleep obsessed und ich brauche aber auch eine GPS Uhr damit ich meinen Sport machen kann.
Great video as usual but disappointed about the 4.0! Not only eternal delivery dates and hw issues but also worse accuracy… 🤦🏻♀️
Are you one of the people on its 3 month + waiting list?
Let's make Oura vs Whoop vs Garmin vs Fitbit!
honor vs huawei band 6 which is most accurate ???
Can you measure the Oura ring?
Is the data inconsistent or improving (showing a trend) over time @ 8:15

Amazing that the newer v4 is worse than the v3. Did you contact Whoop?
Where is the video about Amazfit bip u pro?
👍
Any idea why you switched to dreem2 from the your other eeg device as your control?
Hi Isim! I had some battery and signal quality issues with the other device (it is already quite old), so I have to see if I can get it repaired or a replacement. It was not reliable enough to use for my testing, as too many nights failed. Hopefully I can switch back to using both over the next weeks/months :-)
@@TheQuantifiedScientist hi. First and foremost, thank you for your hard work!
Quick question: is there a way to get Dreem 3 now? Or some sort of an alternative? Like what’s the best/most accurate/convenient tracker money can buy now?
This is great and all but I’m still “4-6 weeks” away from having my new whoop 😒
Whoop 4 sounds interesting but for right now and since I just got my Fitbit charge 5 (sale price 119 dollars), i will stick with this device for the time being - I dont use the Charge 5 premium feature. According to some of your charts, seems some of the Charge 5 is on par with the Whoop.
Subscription pricing of the Whoop 4 kind of turns me off at this time since I am on a tight budget. Would I benefit or understand what all the data the Whoop 4 would give me, I dont know. It is more for a Doctor or health expert to look at than a average person like myself. I want things simple, not all these complicated stats to decipher.
I have done pretty good without this kind of device all my life, do i really need to start now using a Whoop 4 device to tell me what to do. Anyway thanks for all your great videos, you put in allot of effort to explain these devices. take care.
Thanks! Yep, Whoop is a good choice, as it does quite well for most of its metrics. However, it adds up if you have that subscription for a few years!
Do you think the inaccuracies are due to the practical limitations of the hardware or software?
Hardware ofcourse. Software is almost limitless
I've noticed huge improvements with each of the two 4.0 firmware updates. I would guess that the 4.0 will surpass the 3.0 once everything gets refined. Can't emphasize enough that the 4.0 has been barely out for a month while the 3.0 has several years of firmware tuning behind it. New sensors are going to require new tweaks to the algorithms.
I have Fitbit , now te luxe , I have also , polar vantage , and a forerunner 245 .
But I like most the lux .
It’s a same , these gadgets costs a lot of money 💰, and they are not reliable.
That’s why I stay to my Fitbit lux , or charge .
6:35 despite its rather low price, fitbit inspire 2 is the best of them all 😱😱
Will see you as sleeping when on PC or in bed watching a movie. I have to correct the sleeping time every day. The steps are wrong quite often and the weight lifting function is useless.
@@jft8994 you mean fitbit inspire 2?
@@hirumayoichi6533 Yes.
I think you need more than two nights data.
6:31 Oura old is more accurate than new?
Hi! These refer to two Oura 2 rings I own (one is older than the other). This is just for my own reference 😊, so I know which one is which
How come you didn’t represent the Oura 3 ring in your graph on minute 6:40? You even said it was the most accurate sleep tracker with 90% accuracy.
The 90% is claimed in Oura's paper, not measured by the author like all other devices in the chart.
Hi, I'm new to this channel :) I need to track my sleep as accurately as possible. dreem 2 is no longer available to the public, which device do you recommend? Thank you :)
Be absolutely clear that Whoop’s sleep tracker is highly flawed. Last night it recorded that I was “awake” for 4 hours and 35 minutes. Absolute nonsense.
What kind of degree should follow to be a biological data analyst?
biology and stats
Hi Shehan. Some universities offer courses/degrees in bioinformatics.
@@TheQuantifiedScientist thank you sir. I'm going to follow a molecular biology degree
@@TainuiaKid1973 thank you
Make less confusing graphics
So whoop not only not improve on their notoriously bad sensors…they went backwards in some instances .
Whoop is totally garbage. I had whoop and it has same heart rate sensor issues
I would never buy a Woop Strap because you're locked into paying $30 a month for the device to work. This is an unfair business model. At least Fitbit don't completely lock things down. Let me have access to my data using the hardware I purchase, dammit!
1st
Well done for a totally useless comment
This thing is garbage. I'll pass
