Are you planning to do tests of high-end Garmin watches in the near future?

[@fatcrruise6508]

pixel watch please

[@bassam-e-mansour]

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

[@i1DERProductions]

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?

[@Ultrajamz]

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

[@actorjay]

This is what we've all been waiting for. Thanks for all your hard work to create and analyze the data!

[@TheQuantifiedScientist]

Thanks so much Khun!

[@ivenslisboa]

It is amazing the effort that you put in these scientific videos! thumbs up!

[@TheQuantifiedScientist]

Thank you! Cheers Ivens! This is my longest video ever😊

[@enricohagn]

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!

[@yildiraykomurcu]

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.

[@TheQuantifiedScientist]

Hi Yildiray! This is something I would have to check too, but something I will keep in mind for next videos 😊

[@user9b2]

@@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?)

[@jeffmindlin8060]

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.

[@ColonelLucario]

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)

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.

[@tanveerdaswani]

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?

[@caffeinelife]

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!!!

[@TheQuantifiedScientist]

Hi! Yeah, that makes complete sense 😊

[@Bunbunnyart]

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.

[@misha4422]

Great confirmation that I made a good buying decision. I had two primary considerations when I decided to give myself an Apple Watch Ultra for my birthday: 1) That it was from Apple, so would fit in seamlessly into my other Apple-centric hardware/software; and 2) Battery life. The far better battery life of the Ultra versus the other apple watches was a definite draw. The way I have set up and use my AWU, I get nearly three days of battery life.

[@jas0nm]

I love the attention to detail and thoroughness of this video. Thank you!

[@BigBananaDaddy]

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❤

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

[@hansgluck875]

Hey Rob, which of the Apple Watches is your favorite to wear. Battery live NOT taken into consideration? Thank you!

[@edfrederick3630]

Please make a review about the new Google pixel watch

[@TristanPope]

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!

[@michaelcerick9999]

[@nichlaswesterby5609]

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.

[@chusti1054]

Hello Rob. Please test de pixel watch!!!!!

[@HugoGonzalez-fg8gl]

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!

[@kdan2137]

Hi Rob, Can you explain how the Apple Watch SE 2022 has better results for sleeping than the Ultra while they run on the same software? That kinda doesn't make sense somehow. I really want a watch with good sleep tracking, but I really like the extras you get with Apple Watch 8 or Ultra (Oxygen & temperature tracking). But sleep is most important. What is the best thing to do? Greetings from The Netherlands!

[@cenjoz]

Hi! Yes, of course 😌

[@JulienTJ]

@@TheQuantifiedScientist Great!!

[@AlbiBx]

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.

[@mr_m_to_the_t]

Do you also plan to test the new Google Pixel App? PS love your videos!

[@TristanPope]

Can you try to include Resting Heart Rate and Heart Rate Variability accuracy in your tests? I am very interested in seeing which watches (specially since apple watch only takes recordings intermitted and things like Fitbit do it 24/7) which would be more accurate in the overall as these are very important to health stats.

[@graaf33]

Apple Watch can Track way more data for hrv, say yes to afib, and voila you have measurements frequent and always, so you really don’t have to do breath app in the morning

[@TristanPope]

@@graaf33 You can also do this on Fitbit. So.... not sure what your comment even implies. I am just asking for that data to be included in a future review :)

[@graaf33]

@@TristanPope you said that Apple Watch do it intermittent and Fitbit do it 24/7. And thinks that Fitbit would be more accurate. I then said that Apple Watch can also do that.

[@TristanPope]

@@graaf33 Yes the Apple Watch does not track heart rate 24/7 it does it in intervals. And no you cannot change that unless you run a workout all day in which you lose other stats. I am not saying one is more accurate than the other, I am curious to know what tests can show in terms of accuracy. The entire sentence is "I am very interested in seeing which watches which would be more accurate in the overall as these are very important to health stats." Anything in ( ) is ignored for the structure of a full sentence. Meaning before and after the ( ) is one sentence together.

[@emanuelsantos]

Great review! Can I ask a question? To measure HRV, did you use mindfulness app of the watch, during sleep or you activated AF in the iPhone in order to activate more frequente HRV readings? Many thanks

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?

[@leonardrego6714]

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.

[@vitalis]

Can you add Polar watches like Unite, M, V with the H10 band to the sleep tracking list?

[@ShartenHD]

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

[@xander0901]

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.

[@lennart1038]

Hey what watch would u recomend a weight lifter with a lower budget?

[@nxel2]

Cool, the strap might have something to do. Keep us posted!

[@wayne1516]

I forgot but can you add in a sleep architecture of how much deep , light and REM sleep in Minutes you are detecting rather than just stages which is also crucial.

Hi Rob, Is there a way to find the accuracy of the calorie count with the Apple Watch? My normal day at work is about 3700 and if I start an “Other Open Goal” workout I get about 7000 calories for the same amount of work. Are you able to find out why?

How come watch SE 2022 is better in sleep tracking than Apple Watch ultra? Which factor would contribute to this result?

Hi , thank for the video ! Did you notice that the digital crown was moving heavily?!! or its just in my watch ???!

[@RunningOtaku]

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.

Hi Anthony! Indeed quite a surprise 😊

[@JocilynWagner]

Hi. I've really enjoyed watching your videos and am seriously impressed at your dedication in your reviews. My question is, with the Apple Watches you seem to always get the GPS model watches rather than the GPS+cellular models. It seems like there's maybe only 3 cellular carriers in Austria that support Apple Watch so that's totally understandable. But, in this case you couldn't have gotten an Apple Watch Ultra that didn't have cellular connectivity. Do you think this variable could be factoring into why the Ultra scored lower in your testing than the Apple Watch 8 or SE? Thanks for all you do!

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.
