This kind of work per video is extremely helpful and valuable. Consolidating information like this saves people so much time, headaches, and inaccuracies.
@@TheQuantifiedScientist , hello, I am a terrible sleeper and have been for decades. You mentioned that these wearables seem to read better or calculate/show better results for people that sleep well, what do you recommend for a wearable for people who sleep horrible like me?? Do you have any recommendations for wearables for terrible sleepers? or any other options we can look at to improve our sleep with some input from technology? Thank you.
I usually don't leave comments. But man, the amount of work and extensive research you put into your videos are really something to admire, thank you for the great info!
I own a Fitbit Sense 2 and a Fitbit Charge 5. I can confirm, they are tracking sleep different. Even on fitness, they are different. What I recognized, if they are not fitted on the right spot, they're showing divergent data. That's why I'm a little sceptic, when you're wearing three or more at the same time. Anyway, I do enjoy your channel, keep going.
As an experiment, I wore an Amazfit, Polar Unite, Fitbit Sense 2, and Samsung 4 AND Muse S and Dreem 2 headbands all at the same time for six months. The EEG headbands were consistent in their somnographs with the only differences being in the amount of REM sleep. The watches were ALWAYS wrong, especially start times. The discrepancies were huge. The Amazfit was the worst and I stopped wearing it within a month. The only way to compare the somnographs was to align the start times, which I took from the Dreem 2. Conclusion: you cannot rely on smart watches for somnographs. It's a real shame that the Dreem 2 was taken out of the consumer market. The Muse headbands company is focused on meditation (always unreliable). There is no affordable wearable EEG sleep monitor on the market.
The minute my fitbit stopped working, came to watch your videos before buying my next tracking device. The amount of research you present in each of your videos is impressive and is helping consumers make informed choices. Thank you!
@@TheQuantifiedScientist it is very annoying that you plot Polar V, rather than V2 & V3 on your initial graphs. The lack of data from studies is presumably the cause, but it makes the plots useless for most Polar owners. Adding the low end Polar PacerPro in the later graphs doesn't really compensate, unless you can securely state that it uses the same algorithm as the V2 & V3. Likewise the Polar Grit models are totally ignored. In general, not a useful video for me, or most other current or potentially future Polar watch owners !!
@@sja45uk While as a Polar Vantage M user looking to upgrade am interested in a reply, and more Polar device performace comparisons, I do recall that the Pacer Pro was the/one of the highest scoring Polar device in Rob's tests when it comes to HR accuracy, thus best positioned to compare against other manufacturers' "best". Having said that, I wish I were convinced enough by Vantage V3, but HR readings still seem to be inaccurate, even after the latest firmware...
Great video, as usual. I have the Fitbit charge 6 and refuse to give up the battery life and the fact that it solely is a fitness tracker and not like having a phone on my hand. I only let the Fitbit notify me of calls. Good to know it’s still a bit up there in accuracy. I’ve tried premium and basic and found that Fitbit without premium, is still beneficial. Thanks for posting!
Please do more Xiaomi devices. In my country (Brazil) Fitbit, whoopi or Google are not accessible, so we end up using mostly Xiaomi and Xiaomi owned brands such as Redmi, Amazfit and Haylou. Thank you for such a high quality content!
Nice Rob, I give this video ⭐⭐⭐⭐⭐ for sleep content! I'm really excited that we are moving in to new product season, hope Google doesn't quit on the Fitbit trackers.
Bought the Huawei band 9 solely just for my running HR monitor so I can gather some HR data while saving for a more premium running watch. Suprisingly, that watch collect good data of sleep too, just see the time I go to bed and the wake up time, and the duration match and it seems just accurate enough, so i’m happy with the purchase
Hi Rob, great and insightful video, I sleep using a BiPAP NIV to treat CO2 Retention as a result of being born with Scoliosis and Hydrocephalus, I’m looking for the best sleep stage tracker, I do use a Wellue O2 ring to track my oxygen sats and that works well but I want a tracker for Sleep Stages, keep up the great work👍
There was a time when I used the Apple Watch 8 and the Whoop at the same time to see if I noticed a difference in the sleep tracking. I didn't attempt to keep track of it in a scientific manner but I did notice that the Apple and Whoop had different readings for deep sleep and REM sleep. It seems the Whoop fairly consistently gives a higher amount of deep sleep and REM sleep than the Apple Watch. For me it really doesn't matter which one I use. I figure that if I use one consistently and have a data point to compare to how I feel then that is what is important. Also the Whoop does a better job of putting the whole package together.
First of all, thank you so much for been doing review with true data sets. I know we are all waiting for your HUAWEI WATCH FIT 3!! Haha... By the way, I am not sure if you can do some HONOR's review as they MIGHT have really good products in the marketing as well...eg, Honor Watch 4, Honor Choice Haylou watch, Honor Band 9... Thanks!
My comment probably gets buried under so many other comments. I'll post this again : please also test Ultrahuman Ring Air! Having said that - this video is super detailed and helpful! Kudos to you :)
Awesome channel! I've decided to wait for your future updates on Oura Ring 4 and the Samsung Ring before buying anything. Mostly posting to help you get early releases from companies for review!
Always loved your reviews, thank you for taking things to an even further level. Hoping to see reviews on the oneplus watch 2, newest withings offerings and whatever else might come out in the future. Keep being awesome :D
Excellent review. A question. You said apple Fitbit are good if you have normal healthy sleepers. What if a person has really bad sleep issues, verging on insomnia which watches are most accurate to track sleep activity?
You’re the unbeatable master of sleep tracker and I absolutely adore your data charts, plots, and visualizations. Your attention to detail makes it clear you’re German (and that’s meant as the highest praise)! 🙂Thank you for your work!
This is a very detailed and research based post which is just what I was looking for. I have a 30 free trial for a Whoop band and am glad I can return it. It is both more and less than I want. I haven't yet figured out how to adjust the time I am asleep and Whoop doesn't seem to know how to do it either! It seems to know when I exercise, but I know how long I exercise and the intensity so I don't need that info. Plus Apple watch has that capability although it isn't easy to set. I have an older model Apple watch which has sleep tracking and think I will buy a new one. My only hesitation is that the study showing it is great was conducted by Apple. Even if I am not totally thrilled I will have a new Apple watch and no subscription payment. A big thank you for this report.
Just wanted to send a big thanks to you for the level of data, research and unbiased opinion you provide. I haven't even bought a device but I'm sure I will at some point! I'm thinking Oura3 but price and it being disposable (non-replaceable battery) is prohibitive so it's really waiting for a basic skinny strap for sleep tracking e.g. Fitbit3 so I can still wear a normal watch without looking weird! Got a Polar H10 for heart rate as my conclusion from your content is that there isn't yet one device to rule them all. Thank Rob. Keep it up!
Haven't listened to the video yet. But here is my opinion and why. Whoop is great. Mostly because I've been able to wear it 24/7 for 2 years (except for showers) and it is comfortable and gives good data. I tried the Oura Ring. I thought it was good, but could it was uncomfortable, and after a month took it off and never put it back on. (Cannot be great if not comfortable.) My Apple Watch has too short a battery life, so I take it off to recharge every night.
Thank you! I have an Instinct 2 and have inherited an Apple Watch SE 2022. I think my best plan is to use the Instinct for daily wear and use the AW in the evenings for workouts and sleep. I just can't stand the SE battery life!
@@TheQuantifiedScientist I'll be waiting for your review for the watch fit 3 before I buy it, your the only source and RUclipsr to review watches thank you for reviews.
In my country there is a very good special offer on Huawei watch Fit 3 and it's only for 2 days !! Please just tell me that, is Huawei watch fit 3 are good as fit2 ?? This information is enough for me.
Love these reviews. You seem very honest and share important thoughts via proper scientific articulation, which is a breath of fresh air in the field of health, so thanks a ton for that and I hope you'll stick with this! Was arguing whether I should get a tracker again, but decided against it due to my finances being limited, sleep being really bad and the fitbit I used having been very unreliable in this regard, and the other data being not very valueable or actionable. It's a bit of a bummer because I love data, tracking, optimizing stuff and so forth, but I'll stick with my quarterly health assessment (blood pressure,...) and some subjective data/reflections for now. Thanks again!
Thank you Rob! I have been following you for quite some time. I ended up buying a Fitbit that's reasonably good in sleep tracking yet within my budget. Unfortunately Google bought Fitbit and now it's messing with it. I have a feeling I will have to stop tracking my sleep because I can't afford to buy the expensive ones plus the monthly fees. If tracking my sleep caused me stress it's not worth even trying.
@@nd_otd They keep making "updates" to make the app less and less user friendly. Charts and displays have become difficult to view etc. It's a matter of time the entire app will become so user unfriendly that old Fitbit users will all jump ship, me included.
Hey there! I know I've mentioned this before, but I'll keep nudging until it sticks 😄. Could you do a video on the future of health wearables? Specifically, what kind of bio-sensors we might see in the next five years? I'm thinking along the lines of sensors that could measure things like calories in and out, continuous blood pressure, and other game-changing metrics that could help improve health worldwide. Would love to hear your thoughts!
WHOOP vs Fitbit Inspire 3 experience: After a couple weeks of using both devices simultaneously I can say that WHOOP consistently estimates REM and Deep sleep way higher (1.5x, 2x and sometimes even 3x) than my Fitbit Inspire 3. REM: last night Fitbit Inspire 3 recorded 0:30 minutes of REM, whereas WHOOP recorded 2:05h. That's a 4x difference! Deep sleep: Fitbit Inspire 3 recorded 0:58h, whereas WHOOP recorded 1:52, that's nearly a 2x difference. This result was quite consistent across the two weeks, regardless of whether I was using the devices on the same arm, right, left, or both arms. It's frustrating to see the results to be so divergent. I feel that WHOOP overestimates, whereas Fitbit Inspire 3 underestimates. For now, this has reduced my trust in sleep stage tracking with these devices, and will probably not take it very seriously. I'll mostly look at overall sleep length, HRV and resting heart rate to assess health and readiness. Thoughts?
@@Snowmans.Cradle Conflicting info. Apple series 8 shows another thing, Fitbit shows another. Ultrahuman Air another still. 🥴 I use Fitbits above ankle (under sock) for more accurate miles/steps only now .
Good point for bringing the sleep disorders into the game. Considering that none of these devices measures brain waves directly they are using correlations with other metrics using machine learning algorithm and it's quite obvious that everything falls apart when you introduce inputs that are non-typical in the datasets. I had FitBit Charge 5 .. actually two .. and I am not going to get a third one. Not because none of the devices survived longer than 6 months, but mainly because I bought it to self-diagnose my sleep quality and the values I was getting from it were somewhat alarming, but over time I simply stop trusting it. It was simply way too inaccurate for me. Later it turned out that I snore and have breathing issues.
Wow thanks!! I bought the OnePlus watch 2 and I'm curious about its performance. Obviously my expectations are relatively low as it does undercut the competition by some and OnePlus technology is not as mature as the others...
I’ve recently bought the Oura ring 3 simply because I cannot stand Apple Watch on my wrist at night. So the best wearable is the one you will wear, for me.
First video that was recommended to me was your initial review of Apple’s Sleep tracking, and it’s good to see that we’ve sorted out that no girlfriend problem since then 😂
03:48 It's no surprise that there are only few studies dealing with Apple's Sleep Detection. The battery of this product mostly doesn't survive 1 night :D
Rob, outstanding overview. Many thanks. I would be curious if my Garmin Fenix 7 Pro has improved over the previous generations of Fenix products. Garmin, send Rob some new watches for testing!
Great job, thank you! Although I was expecting to see the Mi Watch in this review because it performed well in your test, unlike the Mi band, but unfortunately you didn't include it in the review.
Lets be honest here; According to a large study published by Science Direct 1 February 2024 these reference devices like Dreem 2 head band is anywhere between 55%-82% accurate detecting sleep stages. its like tossing a dice. It does worst on REM sleep detecting .. so if the reference device is off how fair are these tests really ? All your resting should be vs polysomnography
Really seems like junk science, insane he decided to even include parent company sponsored "studies" into his data. This graph is enough to make the pharmaceutical companies in "dope sick" blush.
I looked it up - not a large study at all, only 10 people. Also the study only tested those with a diagnosis of Parkinsons Disease, so not representative of general population.
@@ABC123UIDF There was another study quite a few years back with 25 healthy subjects and for sleep stage they found accuracies of around 82% against polysomnography. So, this would definitely cloud the comparisons. _that being said, It'd just add larger error bars to the points on the plot and their overall position would be the same. I think this is something Rob knows as well, and I hope he could give us a plot of the upper-right corner with the error bars. Essentially, all devices in the upper right corner are fairly comparable to each other
@@abhishekpatra812 The studies are not comparable, one is of a population with a specific disease and avg age of 70. That being said, the study you reference is also relatively weak evidence alone, as researchers had financial biases for this product and the study did not detail any measures put in place for these biases - such as random selection of participants
@@ABC123UIDF The study I'm talking about is Arnal et al, Sleep, Volume 43, Issue 11, November 2020. And the financial bias is that its partly sponsored by Dreem, so the results should be in favor of Dreem. Still they got 82 +- 6% accuracy. Curious about what do you find as a weak result here? I mean sure a, n=100 or more study will be ideal, but those are much harder to do Also, in practice devices like the dream will of-course have lower accuracy than Polysomnography. Do you expect them to be comparable or more accurate??
This a very valuable work. It must be quite time consuming while holding down a job too. I thing seeing how a fairly decent device, like the pixel 2 or Huawei GT4 has changed after a few months of updates would be a fascinating video too.
Damn I wish you were as popular as other youtubers who put all their effort on editing and no effort on the actual content (wasting half of the video on packaging and what not)
Crazy how fitbit inspire 3 si so on top with others way more expensive. I have it and i love it the sleep tracking. I do feel that when I am tired I had a low sleep score and vice versa.
Wellue, and others, ring pulse oximeter appears to be medical grade, super easy to use, to supplement wearables with accurate blood oxygen saturation. High sampling rate picks up hypoxemia that wearables miss. Great for mountains too if you feel faint etc above the treeline. Having said that my specialist physician says to check your hemocrit levels in your annual blood tests. IF ok, any hypoxemia is ok. Your annual blood tests say a lot: "The Longevity Paradox..." by scientist and heart surgeon Gundry. It's easy to measure your youthfulness or premature aging...

Thank you Rob! I have been following you for quite some time. I ended up buying a Fitbit that's reasonably good in sleep tracking yet within my budget. Unfortunately Google bought Fitbit and now it's messing with it. I have a feeling I will have to stop tracking my sleep because I can't afford to buy the expensive ones plus the monthly fees. If tracking my sleep caused me stress it's not worth even trying.
I was considering buying a Fitbit, but reading your comment made me a bit concerned. Can you elaborate on what's google doing with fitbit?
@@nd_otd They keep making "updates" to make the app less and less user friendly. Charts and displays have become difficult to view etc. It's a matter of time the entire app will become so user unfriendly that old Fitbit users will all jump ship, me included.
Hello Rob, thank you for your thorough reviews. Do you intend to make one on the ringconn? Thank you!
Hey there! I know I've mentioned this before, but I'll keep nudging until it sticks 😄. Could you do a video on the future of health wearables? Specifically, what kind of bio-sensors we might see in the next five years? I'm thinking along the lines of sensors that could measure things like calories in and out, continuous blood pressure, and other game-changing metrics that could help improve health worldwide. Would love to hear your thoughts!
WHOOP vs Fitbit Inspire 3 experience:
After a couple weeks of using both devices simultaneously I can say that WHOOP consistently estimates REM and Deep sleep way higher (1.5x, 2x and sometimes even 3x) than my Fitbit Inspire 3.
REM: last night Fitbit Inspire 3 recorded 0:30 minutes of REM, whereas WHOOP recorded 2:05h. That's a 4x difference!
Deep sleep: Fitbit Inspire 3 recorded 0:58h, whereas WHOOP recorded 1:52, that's nearly a 2x difference.
This result was quite consistent across the two weeks, regardless of whether I was using the devices on the same arm, right, left, or both arms. It's frustrating to see the results to be so divergent. I feel that WHOOP overestimates, whereas Fitbit Inspire 3 underestimates.
For now, this has reduced my trust in sleep stage tracking with these devices, and will probably not take it very seriously. I'll mostly look at overall sleep length, HRV and resting heart rate to assess health and readiness.
Thoughts?
Excellent review as usual!!! Great work 👍👍👍
Looking forward to watch your Ultrahuman ring review!
If enough of us mention this he might, I've had one for 8 days now.
@@george6252 What can you say about its accuracy? Can you compare it to other devices?
@@Snowmans.Cradle Conflicting info. Apple series 8 shows another thing,
Fitbit shows another. Ultrahuman Air another still. 🥴
I use Fitbits above ankle (under sock) for more accurate miles/steps only now .
Thank you for your accurate reviews. Would be nice to include some about Ultrahuman ring tho 👌🏼
Good point for bringing the sleep disorders into the game. Considering that none of these devices measures brain waves directly they are using correlations with other metrics using machine learning algorithm and it's quite obvious that everything falls apart when you introduce inputs that are non-typical in the datasets. I had FitBit Charge 5 .. actually two .. and I am not going to get a third one. Not because none of the devices survived longer than 6 months, but mainly because I bought it to self-diagnose my sleep quality and the values I was getting from it were somewhat alarming, but over time I simply stop trusting it. It was simply way too inaccurate for me. Later it turned out that I snore and have breathing issues.
Thanks for sharing!
thx for the video, i noticed that there is no mention of whoop 4.0?
Great video ! It will be interresting to test the last Withings. My cardiologist says they have the best heart tracking.
Loving your videos!!! So useful!! Any plans to review OnePlus watch 2 in the future? You are the only RUclipsr reviewing the accuracy of smartwatches
Waiting room aswell
Hi! I have collected data, but somehow never got to making the video yet...
@@TheQuantifiedScientist That is amazing to hear!!
Wow thanks!! I bought the OnePlus watch 2 and I'm curious about its performance. Obviously my expectations are relatively low as it does undercut the competition by some and OnePlus technology is not as mature as the others...
I’ve recently bought the Oura ring 3 simply because I cannot stand Apple Watch on my wrist at night. So the best wearable is the one you will wear, for me.
Great one!
can you please review the ultrahuman ring ?
The video I was waiting for!
First video that was recommended to me was your initial review of Apple’s Sleep tracking, and it’s good to see that we’ve sorted out that no girlfriend problem since then 😂
03:48 It's no surprise that there are only few studies dealing with Apple's Sleep Detection. The battery of this product mostly doesn't survive 1 night :D
Looking forward to more smart ring tests.
Such a comprehensive review! Awesome job. Subscribed!
Really illuminating video, thank you.
I would like to see your analysis of the newer RiigConn Gen 2 stating Sleep Apnea 90% detection accuracy.
Huawei Watch Fit 3, please!
Thank you for a high-quality video with a lot of literature review and analysis!
You should make pression to bring Dreem headband back to ordinary people market!
Good summary ! The only problem with Apple is size, cost, battery life, so for similar result, the fitbit wins no ?!
Rob, outstanding overview. Many thanks. I would be curious if my Garmin Fenix 7 Pro has improved over the previous generations of Fenix products.
Garmin, send Rob some new watches for testing!
Thank you for the video. I think none of these are good enough for me with poor sleep.
Thanks for your efforts, just learned about this channel and subscribed ofc!
So good! No nonsense biasness like other youtubers. Thanks a lot mate!
No problem 👍
Great job, thank you! Although I was expecting to see the Mi Watch in this review because it performed well in your test, unlike the Mi band, but unfortunately you didn't include it in the review.
Lets be honest here; According to a large study published by Science Direct 1 February 2024 these reference devices like Dreem 2 head band is anywhere between 55%-82% accurate detecting sleep stages. its like tossing a dice. It does worst on REM sleep detecting .. so if the reference device is off how fair are these tests really ?
All your resting should be vs polysomnography
Really seems like junk science, insane he decided to even include parent company sponsored "studies" into his data. This graph is enough to make the pharmaceutical companies in "dope sick" blush.
I looked it up - not a large study at all, only 10 people. Also the study only tested those with a diagnosis of Parkinsons Disease, so not representative of general population.
@@ABC123UIDF There was another study quite a few years back with 25 healthy subjects and for sleep stage they found accuracies of around 82% against polysomnography. So, this would definitely cloud the comparisons. _that being said, It'd just add larger error bars to the points on the plot and their overall position would be the same. I think this is something Rob knows as well, and I hope he could give us a plot of the upper-right corner with the error bars. Essentially, all devices in the upper right corner are fairly comparable to each other
@@abhishekpatra812 The studies are not comparable, one is of a population with a specific disease and avg age of 70. That being said, the study you reference is also relatively weak evidence alone, as researchers had financial biases for this product and the study did not detail any measures put in place for these biases - such as random selection of participants
@@ABC123UIDF The study I'm talking about is Arnal et al, Sleep, Volume 43, Issue 11, November 2020. And the financial bias is that its partly sponsored by Dreem, so the results should be in favor of Dreem. Still they got 82 +- 6% accuracy. Curious about what do you find as a weak result here? I mean sure a, n=100 or more study will be ideal, but those are much harder to do
Also, in practice devices like the dream will of-course have lower accuracy than Polysomnography. Do you expect them to be comparable or more accurate??
Great content! It would be cool to see your take on software from 3rd parties on the Apple Store. Specifically AutoSleep
Huawei watch fit 3 Whennnn
Great work by you. !!
Can you suggest a nice smart device for tracking/preventing night terrors. It would greatly benefit. !!
Thank you for all the effort in reviewing
This a very valuable work. It must be quite time consuming while holding down a job too.
I thing seeing how a fairly decent device, like the pixel 2 or Huawei GT4 has changed after a few months of updates would be a fascinating video too.
Please have a video about Huawei Watch Fit 3, Huawei Watch Fit 2 is so good, but we want to know its upgrade
Will you be doing a breakdown/analysis of apps like Athlytic and Superset (now Bevel)?
Damn I wish you were as popular as other youtubers who put all their effort on editing and no effort on the actual content (wasting half of the video on packaging and what not)
Great video! Why haven't you included the Polar Verity Sense in this review?
Are you planning on reviewing any of the recent Withings products?
Please test apple watch + Athlytic , according to your graph this should be the best solution in regards of sensors, accuracy & price.
Please do a video on the Apple Se !!
(I mean an update, because we're not really sure it's as good as your first test proved)
Crazy how fitbit inspire 3 si so on top with others way more expensive. I have it and i love it the sleep tracking. I do feel that when I am tired I had a low sleep score and vice versa.
When are you publishing the Oura 4 review?
Wellue, and others, ring pulse oximeter appears to be medical grade, super easy to use, to supplement wearables with accurate blood oxygen saturation. High sampling rate picks up hypoxemia that wearables miss. Great for mountains too if you feel faint etc above the treeline. Having said that my specialist physician says to check your hemocrit levels in your annual blood tests. IF ok, any hypoxemia is ok. Your annual blood tests say a lot: "The Longevity Paradox..." by scientist and heart surgeon Gundry. It's easy to measure your youthfulness or premature aging...
Hi! Rob, please review Huawei Watch Fit 3. Thanks!
Is there any review for ultrahuman ring air?
Thank you so much friend ❤
