I didn’t think I would say this, but you might want to think twice about getting the Apple Watch Ultra 2. Or maybe a better wording is that I am personally conflicted about this watch. I have collected a lot of data with the Apple Watch Ultra 2 over the last 10 days, and what bothers me is that it doesn’t seem to be any better, and might even be worse in some cases, than the Series 9, even at things that the Ultra 2 should theoretically be better at. But you can judge yourself based on the data I will show you in this video, and there is plenty of data to share. Specifically, we will be testing the heart rate tracking accuracy of the Ultra 2 on myself and Theresa for a total of 42 workouts, and I’ll test the sleep stage tracking performance with 5 nights of data, we'll be looking at the GPS tracking consistency using 18 bike-rides and we’ll check the oxygen saturation measurements using 100+ datapoints. Let’s get to it!
Hello everyone! For those of you that are new to the channel, my name is Rob, and I am a postdoctoral scientist specializing in biological data analysis. I’ve put the Ultra 2 through some rigorous testing, and the results are super interesting. And to see if a big watch like the Ultra 2 also works on smaller wrists, I tested it on Theresa as well. As you might have noticed, my reviews have gotten quite long recently, so I’ll try to be a bit more concise, but I’ll upload the full results to my website. But, no promises, since I might get carried away and make this a long review anyway. However, first some quick basics about the Ultra 2. How is the Ultra 2 different from the Ultra 1? The screen is significantly brighter, now putting out a max brightness of 3,000 nits compared to the 2000 nits of the Ultra Generation 1. - Наука та технологія

Garmin Venue 3 testing soon?😢
Hi... I follow all ur scientific reviews... I request you to make a review on latest fitbit charge 6 please. Thanks in advance.. after viewing your review abt samsung watch 6, i dropped my thought to have it .
Thanks
I was wondering if you could kindly do a comparison for the Huawei watch ultimate which is known as the Apple Watch killer and Huawei flagship model for watches.
@@Theo_Isaacs Nothing compares to Apple Watch. No such thing as Apple Watch killer. Especially Chinese spy company
This whole video and especially the “side by side” at 11:18 epitomizes how helpful you are Rob! Can see your love for this and you need more subs ASAP.
Rob, you can actually opt in to the Watch OS 10 beta to test out the double tap if you’re interested. I did it with my S9 and find the double tap quite useful actually
The Ultra 2 has been a lot better at tracking my heart rate on runs than the Ultra 1 was on my skinny wrist. To fix cadence lock on my U1 I had to wear the watch further up my forearm. With the U2, I can wear it on my wrist without it mistaking my running cadence for my heart rate.
Out of curiosity what made you risk getting the new one? I work out every single day and use my ultra 1 23 hours a day. Based on the keynote, there was nothing that made think about upgrading.
He lies to himself... 😅🤣😂@@TheSonyExperience
@@kafka27 Maybe... or my U1 is on the bottom of a lake. I guess both could be true.
@@tendojoe seriously??? If so what band so I know to stay far away from it!
@@rctruxbashing7420 It was the trail loop. But I'm going with user error. I think I just tightened it down way too much. It's still my favorite band.
Awesome video as always.
We also need a review of the new Pixel Watch 2. The first one wasn't that bad, hopefully they improved in this new generation. Could you also talk a bit about the overall battery life?
I look forward to seeing your scientific approach to the new Fitbit and Google pixel watch devices that recently came out !
Cannot wait for the Venu3 Review.😊 Keep up the good work!
I bought the apple watch 9 as my first smart watch because of the sleep tracking and accurate HR measurement. I am constantly following your channel, it is a great help for users before buying a smart watch/sports watch. Thank You!
...the apple watches don't track the short naps as the huawei does...I have AWU 2 and I was very disappointed...
Rob, immer beeindruckende Leistung! These are the BEST reviews on UA-cam. Actual data, objective facts. You are an excellent engineer/data scientist! Your results are the driving force for me to abandon Fitbit (and hence Android/Pixel) for Apple's ecosystem (not yet, as IOS is still too dumbed down IMHO, and iPhone 15s are so new to USB [never lightning for me!!] ). Regarding the GPS tracking, it is interesting that the Series 9/Ultra 2 shifts were REVERSED - SW/NE on your rides TO work vs FROM work. The Series 9 biases left, and the Ultra 2 biases right. Thoughts?
Your videos are simply unmatched! My odd request would be a video about how performance is impacted when wearing wrist trackers on other parts of the body (e.g. biceps). Some sources claim HR tracking actually improves for example. For me, the Apple Watch offers exactly what I need, but I generally prefer to wear analogue watches.
One thing I just realized watching this very detailed analysis is that you may need to go back to testing the older apple watches with the newer iOS update(s). I believe the apple watch 7 and 8 should be nearly identical… this may be just margin of error as well.
Agreed
Excellent as always. This confirms my impression that for OHR Apple is the best currently possible (I have no intention of getting one, but I'm still watching Rob's reviews because I'm interested) as it is for sleep tracking (no interest to me with my 72 year old bladder). On Rob's advice, I got an H10 and a Verity Sense and I'm very pleased with these so I haven't bought any smartwatch yet. I might do, depending on Rob's review if he does one, but I'm not saying what it is as he already has enough testing to do without me trying to influence his choice. I'm pretty sure I would be happy with any of the big names which work on Android- GPS is already better than I will ever need. Thanks again
Hey Rob! Thanks so much for your work here, I love your videos. I mentioned it in a comment before, I suffer from panic attacks and I find the AW so helpful knowing the HR is so reliable on the apple watch series 9., thanks to your videos. It gives me peace of mind.
I do have a request though :D I had a whoop before and I loved the HRV readings, but in the end I found it was making me anxious about performance as soon as I woke up so I stopped the subscription. I was wondering though, could you do a video on how accurate the HRV readings are from the apple watch series 9, please?
When will you upload the pixel watch 2?
I have to wait for it to release like everyone (would love to have it sooner😊). Tried to get in touch with Google/Fitbit in multiple ways, but no response...
They should definitely make you part of team pixel
@@craigward26big companies tend to get a cooperation with biased reviewers. Too much critics means no longer early products
When you buy it for him
I'm waiting on getting a 8 based on the results of the pixel 2
Great review Thank you Rob! Love the details. Can you let us know the software you use for the heartrate comparisons please?
Amazing review! Could you maybe run a review on different apps for sleep tracking (sleep cycle, auto sleep etc)? I think
That’s super interesting. I wonder which one is best to detect different sleep stages or if Apple standard sleep is the most accurate among them.
Thanks a lot!
Incredible review! Thank you
Your reviews help me make rational purchases. Keep up good effort!
Hi Rob! Nice video (as always). Are you planning to test the Ultrahuman Ring too?
Amazing work! As usual 👍
could an software update fix the sleep tracking (thinking you didn't go back to sleep)? or is it a sensor issue
Hi Rob, is HRV tracking on high-end Garmin watches much more better than on AWU2? I saw your video with the false HRV values on AW in past.
It'd be really interesting to see a side by side data comparison of ultra 1 vs. 2 both running the latest watchos 10.
Amazing channel and great quality reviews. @The Quantified Scientist would you please consider testing Casio G-Shock GBD-H2000 or GBD-H1000. Thank you!
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!
I think it's mainly a software issue, you should probably test at least on the public betas
INCREDIBLE JOB TESTING THE Ultra 2!! 👏👏👏 Since the wayward data points are for slower heart rates, is it possible the Ultra 2 is not sampling the heart rate as often as the Polar and is simply not grabbing the heart rate data when the heart rate quickly dips to a low rate? Also, and I apologize for even asking this as I'm sure you've considered it, but do you compared the heart rate of your Polar to several other "reference devices" to make sure the Polar is spot-on and worthy of being your single reference devices during these tests? I mention this because I know when testing the performance of power meters, usually they are compared to the values of at least two other reference power meters whose data has been well documented. Since the Ultra 2 has just been released and we are still in the earlystages of WatchOS 10 (which is still a bit buggy), it will be interesting to see if Apple addresses some of this anomalous performance in future updates.
I know this may not be the best wording for this question, but I am very curious about which watch is most accurate for total calorie burn?
Glad you noted the issue with Sleep Tracking if you snooze past the alarm, it’s super annoying!
Is only for Ultra 2?
@@sudiyy nope, have issue on Series 6 and 7. If you snooze past the alarm then it ignores sleep.
Same here. If you get up to use the bathroom close to the alarm time then go back to sleep, it doesn’t record anymore sleep. If I wear my Garmin Fenix watch and the Apple Watch Ultra (Ultra 1), and sync my Garmin sleep data to Apple Health, it adds the missing sleep data.
Hi Rob!
It would be great if you would be willing to do a thorough analysis of the Athlytic app in the near future.
I'm very curious about your thoughts on this.
Kind regards! 🙂
Really interesting! For GPS reviews, instead of looking at tracks, can you lay out a precisely measured course of at least 1 KM and then test the watches on 10 runs over that course to compute the accuracy and precision?
At 31:03 you start talking about the difference. To be clear did you also switch the ultra 2 en the 9 between left and right wrist? I notice difference when wearing the gps device on the left if richt side.
So what’s the bottom line, would you buy the AWU2 or the series 9?
I'm a subscriber & I really enjoy your videos. But I can't help wondering whether it's a mistake to draw conclusions about specific watch generations, while working from an extremely small hardware sample size. (n=1? n=2?)
Much of your data is at such a granular level that I can't help wondering how much variation can be expected between different watches in the same generation. Is your Apple Watch Ultra 2 really slightly worse than the original AWU or is the particular AWU 2 you received from Apple - just slightly worse than an average AWU 2? Or was your AWU 1 slightly better than an average AWU 1? Have you ever looked into this kind of variation? Thanks!
Wow, impressive work !!!
Hi Rob, i have a question. Did you make an Video about the Huawei Watch D? I can not find it.
HI, I was wondering could you include swimming in your future test data? As there are quite a lot of water based activity with the Apple Watch especially with the Apple Watch Ultra.
Hello! I was wondering if you the gps accuracy would change depending on where we lived.
Thank you and please never stop making these!
It absolutely can and does. Also the weather can affect it.
you're the best!
I only trust the results from your reviews when buying wearable devices.
Facts he’s my go to, he needs more subs
@The Quantified Scientist - Amen to what you noted about the Apple Watch creating an AI based chat for insights to health. I see the Pixel Watch 2 has something similar, In reality what has brought the most change and learning experience to my life has been the Oura Ring and Whoop. Even though I have the Ultra 2, having the Oura and Whoop had made me seriously consider the Pixel Watch 2. Thanks again for excellent video and research. Always love watching your channel and learning so much.
I noticed you ended up advising to the get a bunch of different devices but don’t tell us which one would be the one that works better for all. I use my AWU and I loved it and I am a marathon runner. I am going to start trading in using the polar h10 now to get a more reliable heart rate because AWU might be great but it isn’t perfect
Which is the best for running and sleep tracking?
Been binging your reviews they’re awesome!
Glad you like them!
@@TheQuantifiedScientist I’m curious, can I wear my Apple Watch on the inside of my wrist? I generally like wearing my watches this way, it prevents damage and is easier to look at for me.
Can you do an updated version of the apple watch ultra 2? maybe it's gotten better or maybe its worst.
Review the pixel watch 2 when it comes out before 16 October as it's discount only by then
Thank you for your review. Apple watch is the best everyday watch and that is why I will be getting the series 9. If Ultra can match the GPS tracking in the mountains of the Garmin then the apple watch should be almost perfect overall. I used your video on what watch I will buy to my parents. Thank you and more power to your channel
I noticed that you haven't done a review on Polar Vantage V2, but you did a review on the Vantage M. Today, Polar just released a Vantage V3 and I was wondering if you could do a review on it. I love your videos and I would appreciate it. Thank you so much!
Great review as always !
You're my reference in wearebales!
It would be really helpful to have your review about some apps you sometime name such as Athlytic because I'd like to have more metrics about sleep for example.
Apple watch can be the best but we need some more explanation about health results .
Thank you ❤
If you get up to use the bathroom close to the alarm time then go back to sleep, it doesn’t record anymore sleep. If I wear my Garmin Fenix watch and the Apple Watch Ultra (Ultra 1), and sync my Garmin sleep data to Apple Health, it adds the missing sleep data.
Hi, will you be reviewing the frontier x2 heart rate monitor?
Are there any differences between ultra generation 1 and 2 in terms of GPS? Both appear to be dual band
Could wrist movement be mitigated by wearing the strap a bit tighter? Not necessarily SQUEEZING your arm but at least tighter to the point where it doesnt move.
Please review the new pixel watch 2 🙌
Are you going to do review for CMF(by Nothing) watch pro?
Amazing video 👍
Review the new Fitbit Charge 6 please
Does the AWU2 pair with the polar veristy sense .
Mi Band 8 Pro review please! 🙏
Apple Watch SE 2nd generation or Apple Watch series 9?
I’m a 28 year old guy who goes to gym 5 days a week, who completes 10-12k steps everyday. I’m thinking to go for the gps version from the above mentioned watches.
Can you test Honor watches? They don't have restrictions like Huawei and it would be nice to see if they are similar performance
Can you please make a video for pixel watch 2?
Can you compare it to the Huawei Ultimate?
Perfect reviews!! 😃
looking forward to the Google pixel watch 2 review!
The samsung watch 5 pro got a huge update lately. The HR sensor feels much closer to medical devices. It would be nice to redo a test with this device, it's a good apple alternative that people choose. Would you consider retesting it? Cheers
lol
I would like a review of Athylitic vs Oura vs Whoop App
PewDiePie is getting really scientific with these reviews I love it! 🤜🤛
The deviation of the HR sensor results at the low heart rate could actually be due to the higher weight of the Ultra compared to the Series 9. The lower heart rate indicates running phases with a lower cadence, which leads to a higher vertical oscillation, maybe you should review the data parallel to the cadence.
Hi man,what about Huawei Watch Ultimate?Cheers
The sensor for the series 9 and Ultra 2 are the same.
Since sleep tracking does not only depend on the device, but the software used is equally important, it would be really interesting to see tests of the sleep tracking performance of various apps (e.g. Pillow) on a high quality smart watch like an apple watch 9.
Can u compare the carbinox smartwatch- vortex, xranger.
Can you do your analysis for nothing cms watch pro
Hi will you try the Pixel watch 2 also?
another great work done. appreciate the video
Glad you enjoyed the video! Thanks for commenting!!😊
I'm waiting for the pixel watch 2 review! Maybe the new android go to?
please do the CMF watch pro
Could u do a scientific review of Xiaomi Band 8 Global version
Please, test the new Polar Vantage V3!
A whopping 64 gigabytes of storage on the wrist this year compared to 32 on the OG Ultra shouldn't be slept on in my opinion, given how long Apple Watches get software support and how handy it might be in the future.
This is so true that’s a big reason why my first Apple Watch is the ultra 2
Please test the Amazfit Band 7
It's great. I find it very accurate on HR. But oh my does apple have a long way to go with the app
Can u pls review Fitbit Charge 6
Can you do a review of watch called kieslect
can you please test the ZMax against polysomnographie and throw it on the chart in blue because I have the suspicioun that the apple watch is as good as the Zmax, this whole chart is faulty
we are waiting for a test of the new apple watch es 23
how much does an actual Polysomnography device cost? How hard is it to get it? How comfortable is it to sleep with one? How understandable is the data to a lay person?
I think it would be super cool if you did a video on this kind of (non-consumer) device as well.
The Apple Watch may be kinda good but still is not the gold standard (actually measuring brain waves).
Great videos. 🧠✌
Returned mine bought through Amazon good returns policy just had too many weaknesses to justify £800 for a watch which already sells £500 s/h. Watch 6 does the same for half the price.
Time for a review of fitbit charge 6?
Do the comparision for Pixel 2
Valuable content as always ! cheers from the middle east

What about garmin?
I am experiencing major errors in laps in pool swims.
The ultra two is double the price of a series 9 45 mm in the uk,ones 800 ones 400,the 45mm watch 9 sits better on the arm so it’s more reliable as a heart rate monitor.I also have a galaxy watch classic 47mm and the heart rate monitoring is a mess unless you sitting still.
