I love your videos Rob!! I’ve gotten a whoop strap and switched from Samsung to apple based on the videos you post. It’s truly appreciated and I hope these companies recognize your hard work and start compensating you or at least send you the watch to test!!
Now that we have newer Apple Watches with known better sensors to track sleep/EEG, HR, HRV, & SpO2, could you revisit the sleep tracking apps (Sleep Cycle, AutoSleep, Pillow, etc) to see what apps might be best? Thanks for your amazing research!
@@TheQuantifiedScientist Hi there! I see your friend Lisa is wearing a Muse Gen 2, how was sleep detection of that device? Would you ever rate one of those Muse Gen 2 devices?
I found this channel in my search for a suitable budget fitness watch but have greatly enjoyed the content you produce. Using scientific methods and showing graphs and tables really tickles my mind in a good way. Keep doing what you do, it is like a mix of post-grad work and fitness, both things I enjoy!
It would be nice if Rob also tested the Apple Watch on an older adult. I'm 68 years old, and while my Apple Watch SE2 agrees fairly well with my Dreem2, the results are not nearly as similar as Rob has been reporting in his most recent series of Apple Watch family sleep tests. I suspect that Apple's sleep algorithm has been developed using data that is heavily weighted toward younger adults and therefore may not be as valid for seniors.
@@TomKarches Tom, we can only hope that more of the sleep tracking companies invest in research with appropriate representation of older adults so that they can provide persons like us with more accurate sleep data than they currently report. I invested in a Frenz sleep headband since writing my comment above and it is just as ludicrous in its generosity with regard to deep sleep detection as the Apple Watch SE can be stingy. It was routinely reporting well over an hour, and several times over two hours of deep sleep despite the fact that the average for someone my age is ~25-35 minutes tops. Furthermore, they have yet to refund my money ($500+!) as promised even though they've had possession of my returned unit for over a week. Don't be tempted with the Frenzband like I was!
Even though I wear the SE2 watch a purchase based on Robs older videos his videos are a must watch. I do remember that same problem with the Ultra being loose on the wrist expressed by you in the past. Luv it when the less expensive products out preform the more expensive ones.
Danke fur sharing your scientific test results of both Apple Watch Ultra and Apple Watch 8 which are very informative. I have been using my Apple Watch Ultra over the past months for monitoring my sleep and I felt my Deep Sleep was way too short and now realized it was underrated and some of my Deep Sleep hour may have spilled over to Core or Light Sleep, according to test results.
Hello Litang. Same with me. I get these sleep where there is only TINY of the TINY Slivers of "Deep Sleep" and just straight light sleep. I was highly suspicious of that and now it just proves that the Algo that Apple uses for Sleep isnt that reliable for SOME people.
This convinced me to get an Apple watch for the first time. I've been having trouble sleeping for years but I'd like to start tracking and documenting it. I love these videos! I'm hoping my wife will too. She's an actuary and LOVES data, charts and graphs.😅
@@ilcomendante When is ever "think less" the answer? If you notice a problem, you need access to accurate data so that you can measure which possible solutions work for you and which do nothing. Thinking happy thought and burying one's head in sand helps nothing.
Can’t wait to see the whoop compared! My whoop sleep pattern is very different than my Apple Watch 8 with Apple Watch similar to yours with all my deep sleep at the beginning of the night and whoop with deep sleep throughout the whole night and typically an hour longer than what apple says. Makes me question whoop data as they say they favor the later stage of deep sleep for hrv reading which is a huge portion of the recovery number
@@TheQuantifiedScientist I am leaning to a Apple 8 or SE from your videos. I just cancelled my Whoop 4.0. But can you do some testing on the Coros Apex 2, Pacer and Vertix for HR and Sleep? I use this for running but wondering If I can trust it for those two.
Now I really wish you could do another test with the apple watch 8 and a female! To see if a smaller watch and tighter fit actually make a difference? Maybe you could lend Theresa your headband for another Test? (a second test in the sleep lab would ofc be amazing too, but probably more difficult to organize)

Hallo Rob, do you think there is a difference in sleep tracking capabilities between Apple Watch 5 and Series 9, with both having the newest WatchOS installed? Is there a difference and is its worth buying a new model? Also, which app is the best? You said in another video that the whoop and also Oura Ring apps are among the best (if I remember correctly), because what Apple offers in terms of app is only the health app which is not great. I seems that the whoop app seems the best, since you can actually track how different factors (like drinking alcohol at dinner before) change your sleep.. right? What do you think? I think only with the Apple Watch 5 I don't get very far... Whats your opinion? Or is the Apple Watch with some app a great combination? Read somewhere else that the SleepWatch app might be a good options? Thank you for all your hard work!
Thanks Rob for the review. You bombarded us with Apple Watch reviews but it is ok. One question. Theresa was wearing Muse S (gen 1) EEG headband as well along with the polysomnography equipment. Do you also have a comparison between Muse S and PSG or Apple Watch ? I mentioned you about Muse S headband long ago and said that it could replace Dreem since it is not available for consumers any more. We are also waiting for Huawei TruSleep™ 3.0 algoritm review. Available on GT 3 SE and Ultra
Now with all that excellent sleep pattern data - which software do you recommend to interpret this data and find relations to other life data like nutrition, physical activities, environmental settings, etc.? Have you made videos on this topic?
Literally biggest problem with the Apple Watch. Best data quality doesn’t mean anything if you don’t get an interpretation. This is the reason why oura is so good
I don’t work for Apple, so I can’t say why they make the product choices they make. HOWEVER, in the United States (and, as I recall, the regulations in the EU and Japan are quite similar), anything that makes a diagnosis is a medical device and must be FDA approved. Having data correlations between sleep quality and lifestyle or nutrition may be flying very close to the sun, with regard to that area of administrative law. This may be why they don’t go out of their way to do that. Having said that, the Apple Watch is an FDA approved medical device with 510(k) clearance for some of the features it has (like it’s atrial fibrillation detection). The problem with adding data correlation between things like nutrition and sleep is that the fda really may want to see some clinical studies showing that nutrition and sleep are linked in the way you are implying and every time you want to mess with the algorithm you’d need new FDA approval.
@@michael_r Issue would be if you used that correlation as evidence of a causal link, even then the individual should use their brain and not delegate their thinking to some other entity. Correlation is understood by scientific thinkers to not be equal to causation. It is a simple concept.
thanks for new cool video :) it would be nice to see overprediction being presented in some numbers, visually its about 30-40% of deep were overpredicted and overall accuracy seems to be in a 60-70% range for deep sleep
Hey guys, which sleep data analysis app do you recommend for the apple watch? Is it possible to use the apple integrated sleep tracking within AutoSleep and is the analysis of the Autosleep app correct? I want to find something like whoop, an app which scores my sleep by a percentage which I can improve on, and also one that tells me what was wrong and how to improve.
interesting - I just checked it out. Do you have one? Thoughts? I just cancelled my Whoop 4.0 so looking for an alternative and leaning towards Apple but this looks good and its a one time fee.
He replied to me that he won't be able to get it and test it for now. But I won't buy it, even with a discount is 810€ and lacks a usable NFC and cellphone connection. No calls, no second eSIM, no nothing. Maybe the next version.
My apple watch detecs only 30min deep sleep nearly every night no matter if i sleep 7 hours or 12h which just can't be accurate ehat could the problem be for that? I always feel good recovered eventough it showing i usually have under 10% deep sleep every night
Any idea where the Apple Watch Series 6 fits with the sleep tracker accuracy? I saw you rated the series 7 almost-as-good as the series 8, and the series 7 appears to have no new sleep-related sensors compared to the series 6. Would that mean the series 6 is almost as good as the series 8 too? Thanks!
Amazing video, thanks. I want to purchase a EEG device like your Dreem 2 to accurately measure sleep stages to augment my Apple Watch 7. However, the Dreem 2 is not sold anymore or supported. Do you have another recommendation for a consumer grade sleep EEG. Thanks for any ideas :-)
Hello, it is really good video, but can you share suggestion for some iPhone application that probably will make a good extended sleep tracking and advise as Athlytic, but free apps? Thanks in advance
Can you share how you setting looks like? I mean like Alarm clock and focus time on your phone? In the handbook of the watch ultra is apple meantion that the ultra can not track more than 4hr track sleep
Can I please request you do a video on sleep watches / apps for people who need to improve their sleep health the most (those with poor sleep patterns). The default apple watch setup (purchase decision at least partially influenced by your videos) doesn't do a good job of tracking when falling asleep outside of pre-defined sleep times eg. falling asleep early because exhausted or napping.
Hey Rob, thank you for all your amazing videos. I have a question but please do not laugh at me as i really not a tech person ,so that is why maybe you have explain before but i still do not get it. May i ask, what is your recommendation if i want to focus on sleep tracker, calories burned. Either Garmin venu 2, Garmin 7 / fenix or Apple watch 8. I hope you willing to answer my question and many thanks before Rob. God bless.
Very interesting, thanks! One detail actually interested me a lot... The many small "peaks" of awake time from the lab equipment (unaccounted for by the AW) were present in the graphs of the sleep tracking of a friend of mine (many) years ago, he was using a Fitbit small band - can't remember which one - while I was using an Amazfit BIP. I didn't trust my bip at that time and honestly... It was a very basic watch that did not even include rem detection, but I kinda didn't trust my friends Fitbit also due to that pattern full of small little awake moments... However... Now I do think that could be more accurate than I thought! Possible that the human natural sleep patterns include those fast awakenings but basically all consumer oriented algorithms cut them out in some way for making the graph more "readable" and easy to digest for the user? Even more... If this is done through trying to tune the algorithm sensitivity to avoid detecting them alltogether (instead of just cutting them off) this could impact the overall performance of the algorithm itself (unsure if I was able to explain myself, here...) In any case, it's so interesting and fun to try to understand how all this works, thanks for sharing all these information in such details that allows me to pretend I understand them 😂
Apple’s own study using 858 people to develop the sleep stages algorithm showed that 38% of deep sleep is recorded as core (Light) sleep for Apple Watch. Two other studies comparing sleep trackers showed Apple to perform worse with deep sleep. There are tons of people on boards asking why 8 hour sleep only getting 30 mins deep sleep. Supposedly Oura ring does better at recording this but worse at knowing when you are asleep or awake. Not sure how his getting his to read so accurate but Apple Watch worse metric is monitoring deep sleep and that’s quoted from Apple themselves.
HI guys I have question non regarding this video. Why the sampling on the HR polar 10 is extremely low on the Apple watch Se 2022 compared to the SAmsung watch 5 Pro video in the spinng, biking, weight lifting. The sampling of the HR polar 10 should be constant in every review.
Great vid. Any chance you will review any of the new Chinese blood glucose, sat, b/p, steps etc watches (E600) and similar..... Truth be bold I only trust your opinions....
could you do a video on how to actually track sleep with the apple watch (settings and all ) particularly naps or general sleep without setting up sleep focus or schedules if even possible. As I just switched from a Samsung and am disappointed by the lack of auto tracking .
It is so unfortunate with all your knowledge that you do not show the actual app and how to read it and all the different buttons to click on to understand how mine looks like others as I only get 9% rent and only one time at the very end, I want to know why minevisually looks different especially on the week and month view so I know what I’m looking at. I was diagnosed with not getting sleep in my 20s but I want to understand the week and month view because I can’t understand all the scattered stuff.
my deep sleep is like theresa. my garmin shows very more normal'er deep sleep results. I always thought it was just me. But it seems that there are certain users where their deep sleep is just detected wrong / poorly with Apple's algo. However, REM and the Light sleep were all detected just fine! Can you do one with Garmin's latest Firstbeat Analytics. I get a more clear picture of my sleep with Garmins Fenix 7s and with the latest First beat analytics algo that Garmin's latest top devices are using. But Theresa's sleep tracking profile is pointing to a glaring inaccuracy of Apple's Algo. When it works on some people, it seems to work great. But when it does not work well on others like Theresa, the results are just plain wrong since the Deep Sleep being measured is basically negligible. That would make the interpretation of the sleep result wildly inaccurate!
@@30mattdavies Well when we see how Theresa's deep sleep sucked, makes you wonder whether certain algos do better with some people. If you just used Theresa's data set, then you'd say that Apple's Sleep Tracking is terrible.
@@dshpeegz Yes I did notice it. But if that was the case, that should affect the other metric REM sleep and REM agreed pretty good. We can't use Light because that is a catch all. Plus if it was too loose, it should detect the movement as Awake which it didn't either. So 1/3rd of the people in this case Theresa has terrible Deep Sleep Detection which is actually quite bad if you use the 1/3 and extrapolate it out to the rest of the population.
We have to do a follow-up on 16:40 with Theresa!! I suspect this isnt bc Apple Watch Ultra being larger on her wrist. Because this is what I encounter with the Series 9 and the AWU.
Great content my friend I really enjoy what you do! I've been looking for android alternative to the apple watch but I have hard time to decide between huawei watch 3 gt Pro and samsung watch 5. Feel like they all lack of something and they are not apple wtch level. What do you think?
I think the best alternative is Huawei Watch 3 Pro. Samsung measures many metrics but measures none of them accurately. See its heart rate and sleep tracking review on this channel. Huawei is on par with Apple in terms of heart rate measurement. It is even better than Apple in that it can do 7/24 measurement. It can also do 7/24 blood oxygen and skin temperature monitoring. However sleep tracking of Huawei is just bad, cannot match to that of Apple. But they updated their sleep tracking algoritm to TruSleep™ 3.0 and Rob hasn’t reviewed it yet. Samsung can measure additional health metrics, that you cannot find in other devices like blood pressure and body composition (body fat, muscle, water ratio). But Rob hasn’t reviewed those features and we don’t know how accurate those measurements are. Blood pressure is a very important health metric. We will see it implemented in every wearable no longer than 2025. You also need to consider about battery life. Regular Apple Watch cannot finish a day and Samsung can last two days best, with Huawei you only need to charge once a week while all of your health metrics get monitored 7/24. By the way, I would wait for Huawei Watch 4 or GT 4. They will be released soon. They will have similar features with Watch Ultra but with an affordable price tag.
@Yıldıray Kömürcü thank you for the answer! I was actually looking for information about watch gt 4 and the release date but there is not much information yet! Anyway I will be patient and wait for it. Thanks again 😉
My iwatch ultra also is not accurate on deep sleep (merges it often with core), rem is extremely accurate for me though. So i get basically the same results as the third person.
Watching this, no pun intended, and revisiting this as now bought a used series 8, Apple sleep tracking ect on the app is indeed getting much better with newer updates, I wonder if people with more hair vs less hair on the wrist effects results 🤔🤔🤔🤔🤔, i also have a cheap smart watch with oled screen and the battery lasts a week, I’ve turned off as many battery draining things including always on display and different watch faces drain less, how come my cheap watch lasts a week vs Apple Watch 8 one day 🤔🤔🤔
Hey Rob thank you for the videos! If you can look at and maybe preorder and test the Casio DWH5600 when it comes out. I would Greatly appreciate it, I love casio and it's said to use polars algorithms for heart rate and sleep tracking.
Hi, thank you for the video. I currently have an Amazon Halo and it has helped me in sleeping better. Soon, however, Amazon will discontinue the Halo, and I am looking for a new sleep tracker. I am not an athlete, but it looks like the Whoop tracker has a clear, useful app interface. Which do you think would be better for a 75 year old man? A Whoop or an Apple watch?
Apple Watch is better than Whoop 4.0 for tracking sleep. Apple can also can detect a fall or accident so overall the Apple is your better bet and also more affordable over a 2 year period. I just cancelled my Whoop 4.0 after being with Whoop for over 2 years. Hope this helps.
That reference data looks wrong as a sleep scientist. Either you’ve got sleep apnoea and have fragmented REM or it’s incorrectly staging wake/light during periods of tonic REM.
Did you test the pixel watch as well? The Apple watch an pixel watch are my top two contenders right now, and this would really help me make a decision since sleep tracking is the most important feature for me. Main thing speaking against the appel watch for me is that I dont want to switch to an iPhone and would have to use some workaround with a used iPhone to connect my Galaxy and the apple watch. edit: If any of you guys have tried using an apple watch and an android phone as your daily driver, whats your experience?
None of this will mean anything to me until someone shows me how to look at the Apple Watch itself and what buttons to click on somebody please help me please please do a review and explain this I need desperate help
Apple - Health App is one of the most useless for interpretation of your fitness and health matrix; they added some trend functions but do not change the overall health app's usage case.
I cant decide with all these reviews scientific genius my budget is 150$ and i need one for weightlifting , calorie tracker , step tracker and sleep tracking what do you recommend? Thanjs
All I care about is calories lost and will pair to my android what watch will be most precise in heart rate and counting calories lost under 300 dollars really appreciate if someone knows
I sleep with an Oura 3, Apple Watch Ultra (snug with the Velcro strap), and Whoop 4.0. Apple Ultra said over 8 hours sleep (0 deep sleep) Oura 3 said over 8 hours sleep (37 minutes deep sleep) Whoop 4.0 said over 8 hours (over 2 hours of deep sleep) This is almost every night. Not sure which os more accurate but Apple Watch Ultra and Series 8 always show me less than 20 minutes of deep sleep a night with over 8 hours of sleep detected. 53 year old Caucasian male.
Man why didn't you say earlier that you were in Salzburg... I'd like to meet you, have a coffee and ask you some questions ??? ... Next time you're in Salzburg, please let me know...

Could you compare using the same apple watch model both in wrist and ankle and see if the data is very different one from another?
How accurate is the deep sleep function on the apple watch? I hardly ever have any deep sleep listed and when I do it's like 5 minutes or less?
I would love to see an test of the Cardiomood strap. Its the first real Whoop competitor and a comparison of those two would be rally interesting!
interesting - I just checked it out. Do you have one? Thoughts? I just cancelled my Whoop 4.0 so looking for an alternative and leaning towards Apple but this looks good and its a one time fee.
Hey mate, waiting for the Huwaei Ultimate watch test 🎉
He replied to me that he won't be able to get it and test it for now. But I won't buy it, even with a discount is 810€ and lacks a usable NFC and cellphone connection. No calls, no second eSIM, no nothing. Maybe the next version.
My apple watch detecs only 30min deep sleep nearly every night no matter if i sleep 7 hours or 12h which just can't be accurate ehat could the problem be for that? I always feel good recovered eventough it showing i usually have under 10% deep sleep every night
why didn't you includr se as well 😢😢
Any idea where the Apple Watch Series 6 fits with the sleep tracker accuracy? I saw you rated the series 7 almost-as-good as the series 8, and the series 7 appears to have no new sleep-related sensors compared to the series 6. Would that mean the series 6 is almost as good as the series 8 too? Thanks!
Ofcourse chip upgrade and algorithms update help collect better data
Amazing video, thanks. I want to purchase a EEG device like your Dreem 2 to accurately measure sleep stages to augment my Apple Watch 7. However, the Dreem 2 is not sold anymore or supported. Do you have another recommendation for a consumer grade sleep EEG. Thanks for any ideas :-)
Hello, it is really good video, but can you share suggestion for some iPhone application that probably will make a good extended sleep tracking and advise as Athlytic, but free apps? Thanks in advance
Hi Rob, thanks for another great review, you should definitely re review the galaxy watch 5 will the latest updates
Can you share how you setting looks like?
I mean like Alarm clock and focus time on your phone? In the handbook of the watch ultra is apple meantion that the ultra can not track more than 4hr track sleep
Good stuff!
Can I please request you do a video on sleep watches / apps for people who need to improve their sleep health the most (those with poor sleep patterns). The default apple watch setup (purchase decision at least partially influenced by your videos) doesn't do a good job of tracking when falling asleep outside of pre-defined sleep times eg. falling asleep early because exhausted or napping.
Yes, I have irregular sleep patterns and need to track them! What apps can handle this?
Hey Rob, thank you for all your amazing videos. I have a question but please do not laugh at me as i really not a tech person ,so that is why maybe you have explain before but i still do not get it. May i ask, what is your recommendation if i want to focus on sleep tracker, calories burned. Either Garmin venu 2, Garmin 7 / fenix or Apple watch 8. I hope you willing to answer my question and many thanks before Rob. God bless.
Very interesting, thanks! One detail actually interested me a lot... The many small "peaks" of awake time from the lab equipment (unaccounted for by the AW) were present in the graphs of the sleep tracking of a friend of mine (many) years ago, he was using a Fitbit small band - can't remember which one - while I was using an Amazfit BIP. I didn't trust my bip at that time and honestly... It was a very basic watch that did not even include rem detection, but I kinda didn't trust my friends Fitbit also due to that pattern full of small little awake moments... However... Now I do think that could be more accurate than I thought!
Possible that the human natural sleep patterns include those fast awakenings but basically all consumer oriented algorithms cut them out in some way for making the graph more "readable" and easy to digest for the user? Even more... If this is done through trying to tune the algorithm sensitivity to avoid detecting them alltogether (instead of just cutting them off) this could impact the overall performance of the algorithm itself (unsure if I was able to explain myself, here...)
In any case, it's so interesting and fun to try to understand how all this works, thanks for sharing all these information in such details that allows me to pretend I understand them 😂
I wonder if the series 9 is any better, I doubt it tho
Apple’s own study using 858 people to develop the sleep stages algorithm showed that 38% of deep sleep is recorded as core (Light) sleep for Apple Watch. Two other studies comparing sleep trackers showed Apple to perform worse with deep sleep. There are tons of people on boards asking why 8 hour sleep only getting 30 mins deep sleep. Supposedly Oura ring does better at recording this but worse at knowing when you are asleep or awake. Not sure how his getting his to read so accurate but Apple Watch worse metric is monitoring deep sleep and that’s quoted from Apple themselves.
HI guys I have question non regarding this video.
Why the sampling on the HR polar 10 is extremely low on the Apple watch Se 2022 compared to the SAmsung watch 5 Pro video in the spinng, biking, weight lifting. The sampling of the HR polar 10 should be constant in every review.
will I still get accurate results if I wear the apple watch on my bicep instead of my wrist
The Quantified Scientist, please take measurements of the xiaomi mi band 8 indicators🙏🏻
Hola, que reloj me recomendaria para el uso deportivo y un seguimiento del sueño correcto, me podría aconsejar?
Great vid. Any chance you will review any of the new Chinese blood glucose, sat, b/p, steps etc watches (E600) and similar..... Truth be bold I only trust your opinions....
could you do a video on how to actually track sleep with the apple watch (settings and all ) particularly naps or general sleep without setting up sleep focus or schedules if even possible. As I just switched from a Samsung and am disappointed by the lack of auto tracking .
Hi, which sleep tracking app do you use?
It is so unfortunate with all your knowledge that you do not show the actual app and how to read it and all the different buttons to click on to understand how mine looks like others as I only get 9% rent and only one time at the very end, I want to know why minevisually looks different especially on the week and month view so I know what I’m looking at. I was diagnosed with not getting sleep in my 20s but I want to understand the week and month view because I can’t understand all the scattered stuff.
I'd love to see a comparison between PSG and the Dream 2!
my deep sleep is like theresa. my garmin shows very more normal'er deep sleep results. I always thought it was just me. But it seems that there are certain users where their deep sleep is just detected wrong / poorly with Apple's algo. However, REM and the Light sleep were all detected just fine!
Can you do one with Garmin's latest Firstbeat Analytics. I get a more clear picture of my sleep with Garmins Fenix 7s and with the latest First beat analytics algo that Garmin's latest top devices are using.
But Theresa's sleep tracking profile is pointing to a glaring inaccuracy of Apple's Algo. When it works on some people, it seems to work great. But when it does not work well on others like Theresa, the results are just plain wrong since the Deep Sleep being measured is basically negligible. That would make the interpretation of the sleep result wildly inaccurate!
He’s done a couple where first beat we’re integrated with garmin- high level summary… it’s shit, just like the optical hr on garmin
@@30mattdavies Well when we see how Theresa's deep sleep sucked, makes you wonder whether certain algos do better with some people. If you just used Theresa's data set, then you'd say that Apple's Sleep Tracking is terrible.
He said he noticed her watch was loose on her wrist so we don’t know for sure if it’s due to apple or just how she wore the watch
@@dshpeegz Yes I did notice it.
But if that was the case, that should affect the other metric REM sleep and REM agreed pretty good.
We can't use Light because that is a catch all. Plus if it was too loose, it should detect the movement as Awake which it didn't either.
So 1/3rd of the people in this case Theresa has terrible Deep Sleep Detection which is actually quite bad if you use the 1/3 and extrapolate it out to the rest of the population.
can I please look at the laboratory that conducted the eeg?
We have to do a follow-up on 16:40 with Theresa!!
I suspect this isnt bc Apple Watch Ultra being larger on her wrist. Because this is what I encounter with the Series 9 and the AWU.
Deos the apple watch 8 use the same technology as the series 4?
Great content my friend I really enjoy what you do! I've been looking for android alternative to the apple watch but I have hard time to decide between huawei watch 3 gt Pro and samsung watch 5. Feel like they all lack of something and they are not apple wtch level. What do you think?
I think the best alternative is Huawei Watch 3 Pro. Samsung measures many metrics but measures none of them accurately. See its heart rate and sleep tracking review on this channel. Huawei is on par with Apple in terms of heart rate measurement. It is even better than Apple in that it can do 7/24 measurement. It can also do 7/24 blood oxygen and skin temperature monitoring. However sleep tracking of Huawei is just bad, cannot match to that of Apple. But they updated their sleep tracking algoritm to TruSleep™ 3.0 and Rob hasn’t reviewed it yet. Samsung can measure additional health metrics, that you cannot find in other devices like blood pressure and body composition (body fat, muscle, water ratio). But Rob hasn’t reviewed those features and we don’t know how accurate those measurements are. Blood pressure is a very important health metric. We will see it implemented in every wearable no longer than 2025. You also need to consider about battery life. Regular Apple Watch cannot finish a day and Samsung can last two days best, with Huawei you only need to charge once a week while all of your health metrics get monitored 7/24. By the way, I would wait for Huawei Watch 4 or GT 4. They will be released soon. They will have similar features with Watch Ultra but with an affordable price tag.
@Yıldıray Kömürcü thank you for the answer! I was actually looking for information about watch gt 4 and the release date but there is not much information yet! Anyway I will be patient and wait for it. Thanks again 😉
Can anyone tell the mm/size of the Apple 8 watch used in the video?
My apple watch 4 doesnt have light sleep but instead core sleep... is core sleep the same as light sleep?
An off-topic question: what is your indoor cycling setup?
My iwatch ultra also is not accurate on deep sleep (merges it often with core), rem is extremely accurate for me though. So i get basically the same results as the third person.
Can Apple Watch work with an Android cell phone?
Could you do a Mibro watch lite the scientific test? i would like to know it
Are there videos of the Ticwatch 5 coming? =)
I want to know accuracy of SPO2, Heartbeat and sleep of Amazfit Band 7. Please do it review
Watching this, no pun intended, and revisiting this as now bought a used series 8, Apple sleep tracking ect on the app is indeed getting much better with newer updates, I wonder if people with more hair vs less hair on the wrist effects results 🤔🤔🤔🤔🤔, i also have a cheap smart watch with oled screen and the battery lasts a week, I’ve turned off as many battery draining things including always on display and different watch faces drain less, how come my cheap watch lasts a week vs Apple Watch 8 one day 🤔🤔🤔
Hey Rob thank you for the videos! If you can look at and maybe preorder and test the Casio DWH5600 when it comes out. I would Greatly appreciate it, I love casio and it's said to use polars algorithms for heart rate and sleep tracking.
Could you look into something called Whoop your personal digital fitness and health tracker
Hey Rob, which sleep tracker is best at detecting and displaying the very short wake episodes that the reference device detects?
Apple Watch picks up a lot of these for me.
You should check to see how good the Google nest for sleep tracking
Will there be a review of HUAWEI WATCH GT 3 se?
Hi, thank you for the video. I currently have an Amazon Halo and it has helped me in sleeping better. Soon, however, Amazon will discontinue the Halo, and I am looking for a new sleep tracker. I am not an athlete, but it looks like the Whoop tracker has a clear, useful app interface. Which do you think would be better for a 75 year old man? A Whoop or an Apple watch?
Apple Watch is better than Whoop 4.0 for tracking sleep. Apple can also can detect a fall or accident so overall the Apple is your better bet and also more affordable over a 2 year period. I just cancelled my Whoop 4.0 after being with Whoop for over 2 years. Hope this helps.
@@fitnesswithbenlifestyle Thank you for your thoughtful reply, I'll buy an Apple Watch instead of the Whoop.
what app are you using for the apple watch where it detects rem sleep?
Polar vantage v2 - please, do a review 🙏🙏🙏
Will you have a review on the peak 9 pro?
Hey
Can you please make review about Xiaomi Watch S1 Active. Please 🙏
Waiting for review of huawei watch ultimate
What's the next video going to be about?
That reference data looks wrong as a sleep scientist. Either you’ve got sleep apnoea and have fragmented REM or it’s incorrectly staging wake/light during periods of tonic REM.
Hello please test huawei band 8 and mi band 8, please
Did you test the pixel watch as well? The Apple watch an pixel watch are my top two contenders right now, and this would really help me make a decision since sleep tracking is the most important feature for me.
Main thing speaking against the appel watch for me is that I dont want to switch to an iPhone and would have to use some workaround with a used iPhone to connect my Galaxy and the apple watch.
edit:
If any of you guys have tried using an apple watch and an android phone as your daily driver, whats your experience?
None of this will mean anything to me until someone shows me how to look at the Apple Watch itself and what buttons to click on somebody please help me please please do a review and explain this I need desperate help
Bro please try soundpeats smart watches 😂😂❤
Please review Huawei Band 8
Try it again with the Apple Watch Ultra on your ankle!!!
You are the best
Thanks so much!
The problem with Apple Watch is that it doesn’t provide any insight to those metrics, unless you “pay” for those expensive apps !!
@17:37 this is not normal, Theresa needs to see a doctor ASAP! lol
I want see mi band 7 pro be tested
Please test the Garmin 965!
Hi Bruce! I've been waiting for Garmin to send me one...
@@TheQuantifiedScientist but do think the 965is suitable for weightlifting?
They probably won't send one for sleep tracking as Garmin's is trash
@@MaxInNewZealand why is it trash ?
Can you please make a video on best wearables for autistics . Thanks
Makes me wonder if the Apple Watch is actually better than the Dreem 2 device. It wouldn’t be surprising given that Apple uses a much larger data set.
Any chance the Inspire 3 was tested in the sleep lab as well? Bought it to track my sleep after your recommendation for budget tracking
Apple - Health App is one of the most useless for interpretation of your fitness and health matrix; they added some trend functions but do not change the overall health app's usage case.
this channel turn to be apple watch channel🤑
😂😂 I was looking for this comment
I cant decide with all these reviews scientific genius my budget is 150$ and i need one for weightlifting , calorie tracker , step tracker and sleep tracking what do you recommend? Thanjs
I think your tables would be better if they only show two significant digits. 17% not 16.9%
All I care about is calories lost and will pair to my android what watch will be most precise in heart rate and counting calories lost under 300 dollars really appreciate if someone knows
I sleep with an Oura 3, Apple Watch Ultra (snug with the Velcro strap), and Whoop 4.0.
Apple Ultra said over 8 hours sleep (0 deep sleep)
Oura 3 said over 8 hours sleep (37 minutes deep sleep)
Whoop 4.0 said over 8 hours (over 2 hours of deep sleep)
This is almost every night. Not sure which os more accurate but Apple Watch Ultra and Series 8 always show me less than 20 minutes of deep sleep a night with over 8 hours of sleep detected. 53 year old Caucasian male.
Man why didn't you say earlier that you were in Salzburg... I'd like to meet you, have a coffee and ask you some questions ??? ... Next time you're in Salzburg, please let me know...
