Over the last week I have extensively tested the new Apple Watch Ultra for its sports and health tracking performance. And in this video we will take a comprehensive look at the heart rate accuracy, sleep tracking performance, skin temperature measurements, GPS tracking, oxygen saturation measurements and step counting accuracy of this brand new watch from Apple. In this video I will focus on independent and unbiased performance testing of this top of the line Apple Watch.
Overall I am really happy with the performance of the Apple Watch Ultra. It has the same amazing heart rate tracking that all Apple Watches have, though in this case the increased weight might influence the accuracy during more vigorous exercise. The sleep tracking is really good, and Apple really really seems to have the best sleep tracking out there at the moment. The only problem with the sleep tracking is that when you sleep outside of the window you indicate, it might not track your sleep. Unfortunately I never nap, so I have not been able to test what happens myself. However, people have left comments about having issues with this in my other videos. The GPS tracking also appears to be really solid, and at least a bit better than the other Apple Watches. The temperature sensor gave a good first impression, though I really want to know if it can detect large changes in temperature as well. The SpO2 tracking seems pretty reliable, though more testing is needed in a low oxygen environment. And the step counting is also quite accurate, and it does not count too many steps when it is not supposed to, which is really good.
Based on this testing I can say that the Apple Watch Ultra would be one of my first choices as an all-round health and fitness tracker. Especially given the better battery life compared to the normal Apple Watch Series 8. However, that is only true if money is no concern. I do not think it is worth it for most people to spend 800 dollars or more on the Apple Watch Ultra. You will get the most important functionalities for a fraction of the price with the new 2022 Apple Watch SE, as I showed you in a recent video. So, for most people this is the Apple Watch I would recommend. - Наука та технологія

Are you planning to do tests of high-end Garmin watches in the near future?
pixel watch please
My father's birthday is in two weeks, he recently started to exercise once a week on outdoor bicycle trips and I'm thinking to get him the mi band 7 Pro as a gift, can you test it? I wonder if gets enhanced outdoor cycling tracking, if not, what would you recommend for that type of sport in the same budget of a Xiaomi band or a bit higher?
Thanks a lot for your videos
Out of pure curiosity and if it matters, did you also tell each watch which wrist it was on/switch when you changed wrists for accuracy?
Curious where the older apple watch 6 falls on the heart rate correlation chart, some studies saying the apple watch calorie tracking is not good are based on the older models
This is what we've all been waiting for. Thanks for all your hard work to create and analyze the data!
Thanks so much Khun!
It is amazing the effort that you put in these scientific videos! thumbs up!
Thank you! Cheers Ivens! This is my longest video ever😊
Thanks for sharing your awesome quality work, Rob 🙏
Your tests are most probably the most diligently as well as thoroughly performed gadget tests of all the whole YT channels available to the public!
Dude I’m your consistent viewer since 200 subscribers.
I love your scientific tests.(no crap direct to the point).
I also brought Honor band after seeing your review about it.
You make easy for viewers to decide to what to go for.
Thanks man❤
I love the attention to detail and thoroughness of this video. Thank you!
Please make a review about the new Google pixel watch
Yay!!Thanks for the review!!Was waiting for this for almost 2 weeks!
Thanks for all your hard work gathering and showing us all this data!
So nice of you Michael! Thanks so much 😊
Great job, love the dedication that’s been put into this
Very comprehensive review. Thanks
Great in-depth review, thanks for putting in the time!
I upgraded from S6 to the Ultra and I've been more than happy with it.
Stunning work! thank you
Thanks for the great content Rob!
finally bro been waiting for long to be excited!
Thanks so much!😊
Home run, this is amazing, thank you.
Fantastic analysis!
You're pumping these apple watch videos out lately, and I'm loving it.
Thanks for this review! Great job !
Love your videos! The only truly scientific and transparent Apple Watch reviews I can find on UA-cam!
Hi Rob, this is incredibly valuable information, thank you for sharing your findings. Really looking forward to your review on the pixel watch for all of us who don't live in the apple ecosystem
Love your channel Rob !
Tolles Videos! Viel Input, hast du interessant präsentiert 😃
This was an absolutely superb video. One of the best I have ever watched. Thank you for taking the time to go so granular.
Yes! Been waiting for this full review.
Hope you like it Victor!😊
@@TheQuantifiedScientist very much. :) one takeaway from the numbers is that apple watch se 2022 performs very well and sometimes even better that its big brothers and a quarter of the price.
Danke mal wieder für dieses tolle Video 🎈
Fantastic video thank you for all that hard work!!
Thanks for your great review!!!
Great video! Thanks!
excellent review - thorough and professional - well done
Great quantitative analysis of these features. Thank you. But especially enjoyed your gps trip to work in Wien, a city so close to my heart but geographically so far frrom Sydney, AU. I recognised all those wonderful musical venues, street names, buildings etc. Danke vielmals.
Thank you for this review. I absolutely love it
Your smile is contagious. Thanks for your work.
During work I can easily listen to your analysis without worrying about having to see what you're referring to, appreciate the work.
Very impressive, and genuinely helpful, work. Great video, thanks for the hard work!
Hi Rob, there is one more thing I would like to see in your reviews. Can you mention about the maximum frequency of measurement of health metrics in continuous tracking mode (7/24) ? How frequent can the device measure metrics like heart rate, blood oxygen, temperature, etc ? Usually this info is not given by the manufacturer and we only find it out after we buy and when we start using the device and its app.
Hi Yildiray! This is something I would have to check too, but something I will keep in mind for next videos 😊
@@TheQuantifiedScientist Hi Rob, I think the "reasons" for why Apple configured the scanning rates as they did could also be interesting. A balance between what we layman think is better over what the scientific community think is better. (balance between useable date versus battery usage?)
This could be an adjustable metric - are you listening apple ?(answer =no). Sampling rate v battery life could be consumer choice like screen brightness/always on etc.

I can say that on my S6 when I do a workout it can measure an HR value every 0.4ms
Like I have a measurement at 15:10.05 then one at 15:10.09; 15:10.14; 15:10.17; 15:10.24; 15:10.27; 15:10.33
So it can fluctuate between 4ms and 6ms
A bit later it even added a value after only 1ms (15:10.45 then at 15:10.46)
Wow! You gave so much analysis in detail with empirical evidence so consumer can decide what product or brand to purchase. Thank you so much for your contribution 🙏🏽
Love your video.
I'm looking forward to seeing you testing the new pixel watch
You and me both Charlie😊!
Best reviews as always
Thanks, great review
Dankjewel Martin!
Thanks!
Great review 🙌👏👏👏
Thanks for the in-depth review. While the run data is lacking, there are plenty of reviewers who have done extensive testing with running. From their testing, the weight and size of the AWU places greater emphasis on getting a proper fit to maintain accuracy. With some fine-tuning to get the proper fit, the AWU tracks heart rate closely with a chest strap.
Graphs and data galore, love it!
Great video as always! A suggestion- for GPS testing, accurately measure a few courses- open skies, downtown, etc.- of 1 KM and then do 10 trials on each course to measure the accuracy (average distance) and the precision (standard deviation) of each watch. You can see some of my old videos as an example.
Been waiting on this one
Thx a lot
One thing i would really like to know is how accurate the HRV values in smart watches. Could you please make a video about it in the future? If you have the necessary tools, of course.
Thank you for your very detailed reviews!! This helps incredibly to people like me who are more interested on whether they're accurate or not compared to how they look.
I just saw that the Pixel watch came out, are you planning on taking a look at it?
Keep up the amazing work!
Great videos!
Amazing videos! I get so much info about the devices, but also learn a ton about various scientific process aspects as well. One personal opinion, while the star rating is cool as an opinion/recommendation aspect, I would have preferred to see the watch comparison chart for GPS, Step counting and SP02 vs other devices. That to me is the most important "rating". Thanks for all your hard work!
amazing tested, waiting for garmin venu 2 sq thank you
Absolutely brilliant review, been checking back every day to see if you had posted this. Makes me feel good about my decision to buy the Ultra. Just one thing is bugging me big time. I wear the Whoop 4 as well but always have a very big difference between the Whoop and the Ultra with regard to the sleep stages. Question is, is the Ultra significantly more accurate and reliable? If yes, I’m going to give up the Whoop 4.
Great to have new video. Amazing review as always, the amount of effort on this videos is huge. Hope that the video of the Fitbit Inspire 3 is cooking. If Apple had a band instead of a watch with this performance I would definitely get it
I am speechless after viewing how good your video is 🎉🎉🎉🎉🎉
Thank you Rob! Been waiting for your premier level review. I wonder if you would please consider adding swimming to your testing in the future?
This is great! Thank you so much for this detailed reviews. They are really helpful!
Will you review the newly released Pixel Watch?
Let me say thank you for these videos. They’re very accurate and have shaped my decisions in buying the Apple Watch Ultra.
I wanted to see for myself how accurate the HR for Apple Watch ultra was compared to the polar 10 chest strap so I did the test myself during a CrossFit workout and even though there is a very small delay with the Ultra the results were almost identical. It’s amazing how accurate it is I didn’t think it would be so precise. Props to Apple for dominating this field.
P.s. I was worried that the weight of the Ultra would cause issues with the accuracy but from what I saw it didn’t whatsoever . I used it with the Ocean Band and I made sure it was fitted tight.
I love the scientific approach and standards!
Thank!
This is a super expensive study and I’m grateful for your hard work.
Your reviews are amazing!!
You got a new subscriber
Thank you very much for your extensive testing. This is super interesting! Have you considered translating the R-value in HR monitoring into a percentage of calories burned? In other words with a R-value of 0,99 am I then getting a calorie count that’s 99% percentage points of the “real” calories burned?
Great work 💪. It would be awesome if you redid some of the test after big updates to the software. Thats a big ask but im really interested in how this what is going to evolve over time. Thanks for your hard work.
Good job
Hi! Love your videos - really great and helped me make my decision to ditch the whoop for the Apple Watch ultra. Do you recommend any apps that can track sleep and work outs for the Apple Watch - apart from the stock apps? Something like whoop? I’ve tried Athlytic, it’s ok. Something better?
You totally deserve way more likes and subs. Definitely
Amazing review, please do the pixel watch next!! 😃
Hey I don't know if you made a video about this, but if you didn't you should make a video about how we can analyze the sleep cycles and understanding the sleep stages better. It would be great since not many apps give you insights about it and just give you the chart. Thanks
Amazing and very detailed analysis and visualization with the graphs! Seems like the Apple watch Ultra is a super accurate for health metrics.
I love this scientific test! Although not too happy about the run test result, I know it was on one test, but still. It is running I would primarily use the watch for, currently using a S4 which is quite unreliable with heart rate, it tends to show a static and too low heart rate during some of the first few, but someone more, KM, and then seemingly starts to work properly. Not sure why this is, I feel like the band is snug and sensors it’s clean, but I’m hoping a new watch with upgraded sensors could solve this. During walks it seems to work perfect.
Fantastic - just what is required to really judge which is a good choice. Blindingly good video thank you.
Can't wait for you to do the pixel watch I'm really curious about those results.
I got the ultra with the ocean band instead of the cloth bands. It’s very snug and is easily adjustable. I like it better than the Velcro straps I’ve typically used. It would be interesting to see you do a test with a tighter band. I think the watch is top heavy. I actually returned mine because, other than the increased battery life, it didn’t really have any better value than my “old” series 7. I will probably keep the 7 for 2-3 more year unless apple does something significantly different or better. I really like the look of the original Apple Watch better.
As always, you do amazing work. Danke Schön!!!
Hi! Yeah, that makes complete sense 😊
Do you know if Apple would take back the Apple Watch ultra if I lost the outer cardboard-like part of the packaging it came in? I have the box the watch and band came in but not the part that kinda wraps around those two boxes.
Im noticing that the pulse readings are insanely much better on the ultra than on my old aw5
Hello Rob. Please test de pixel watch!!!!!
Thanks for the great review! I’ve been on several runs with my ultra and I think I’m getting higher HR readings too. I didn’t watch the readings closely during the run but there was a significant drop in my VO2 max after my first run with the ultra. Previously I had S7 aluminum and I’m expecting you’re right that this comes down to the weight of the Watch. Hopefully Apple will have a lighter weight option available for the ultra in the future.
Thanks for sharing your experience! I tried the Ultra at the Apple store and it's too big for my wrist. I'm also hoping for a smaller version that can accommodate smaller wrists. I don't mind smaller screen and slightly less battery if they can pull off the same performances.
Hey Rob! I really love your detailed vids! Kudos for the effort. Would love to see the comparison between Apple Watch and Oura with regard to HRV measurements. Which one is more accurate?
Hi Rob, thabks for you amazing work.
I eagerly wait for your reviews.
when you will review Fitibit Sense 2?
hey great vid, thanks! Can you recommend some apps
You are a god of data. I am a ux designer and am learning so much from you.
Hey there! Would be great to get a comparison of Whoop 4 vs Apple Watch 8 using the Athlytic app. I understand that EKG should give a more accurate HRV reading, so the AW+Athylic combo should in theory be a better replacement.
Thank you so much for this review! Would you consider doing swimming tests?
In my experience with the 6, 7, and Ultra there sometimes are a few minutes here and there where the HR sensor does not pick up… would be interested to see if that also happens with other smart watches and also how accurate underwater HR measurements are compared to chest strap.
Please do full scientific reviews with some of the Fitbit devices
Hi, as always a great and very informative video. This maybe anecdotal data after three days working in the office. I’ve noticed that typing generates quite a few for the false steps and it can’t register me standing using standing desk, if my arm is on the keyboard.
Love your reviews. It's extreme in depth review.
Can you please provide Google pixel watch review?
been waiting for this from ages haha
another great and waited review, but you need to include battery testing too, its one of most important specs for most people
Great Video Again!
You should do the new generation of Amazfit
GTR 4 and GTS 4
Apparently the sensors improved a lot.
Your reviews are really great, as an oncologist i love your statisticsl analysis! You ever did a test on Vo2 max accuracy for the apple watch? Greetings from Hietzing, Michael
Thanks so much Michael!😊
This is good analytical data! Can you do this for the Garmin Marq2 also? In-depth analysis for that watch would be nice. Heart rate variability and sleep analysis comparisons and all.
Love your vids... I'd love to see you deep review mi band 7 pro next... I'm doubtful about that one and want to see an informed video before making a decision
Hi! Thanks! You are completely right! This is also still on the list, hopefully I will get to it soon 😊
Hello Rob, I find your reviews super interesting. I am however very interested in something you don't seem to include which is "real world applied metrics". For instance: I did a workout: Spinning, HIIT, Weights, and Spinning again with cooldown in one recording on the Apple Watch Ultra and Fitbit Versa(1) which do not match visually on the graphs. And the graph of the Apple Watch is more accurate / consistent, but the overall Calories burned and Summary of workout match regardless. Heart rate, Calories, time, etc all within a 1-2 margin of error.
What this says to me is that the deviations that we see here, while VERY useful and quite amazing for comparisons between different wearables, when it comes down to everyday use, the practical application of said data, usually lines up in the end.
So the real question I have for reviewers is how important is it for the graphs of heart rates to match the polar H10 strap if their software algorithms are rounding the difference and the margin of error in overall results is pretty much the same for (from my experience) Fitbit, Garmin, and the Apple Watches of the world?
This real world application would be so helpful to see!
Hey Rob,
thanks for your videos ! Love them !
Will you be reviewing the Google Pixel Watch? I'm really waiting for your review before deciding to buy it or not ! Thanks
Idk if its just me but this man voice is so calming, I could listen him for hours
Overall, great video.
Thanks for all your hard work! The new watch looks awesome.
Maybe a caution that you might not want to show where you start your bike rides, since I imagine it's close to your apartment and the internet can be a weird place, but maybe I'm just too pessimistic or maybe you've already offset where you start your tracking from already.
Hey Rob, which of the Apple Watches is your favorite to wear. Battery live NOT taken into consideration? Thank you!
Thank you Rob for one more very detailed analysis. One generic question for you relates to this watch. Did you find annoying that the watch was necessary to be charged frequently and how frequently this was considering your tests?
Great stuff! Could we expect to see a Fitbit Inspire 3 Review and perhaps it's a comparison to the Charge 5?
