Apple Watch Series 7: Complete Scientific Review

[@TrueRay17]

Honestly, you are the best thing to happen to KZbin in the last 10 years. As a person who likes an objective and scientific point of view a lot of the time, I like how you take the data you've complied and make it easier for an average consumer to understand. Which is a gift a lot of scientist struggle to do. I applaud you and if you have a donation link, ill be more than happy to donate to your cause because you are that impressive.

[@braer240]

I was coming to comment something similar. Sad that more people don’t care about this type of data, as im sure it was a lot of work to track and compile.

[@user-vi3fy2cc9z]

[@Ben-io2vo]

it's ok mate glad I could help

[@Coach.RoyHikes]

Wow wow wow, I’m doing research on the Apple Watch 7 to see if I should upgrade from my series 3 and I stumble upon your channel and I am blown away. Started watching about the 7 and ended up watching idk how many other videos lol. Amazing stuff, as a fitness professional I now have a channel I can come to and look for reliable & non bias information. I am truly amazed please continue with the amazing work. You earn a fan today!! Thank you for all this!

[@energysourcelove]

Auto Sleep has added many new features and interpretations. It would be great if you could review that again. I find the sleep reporting to be more accurate and useful than my Oura Gen 3. It would be great if you reviewed agin since it has been over a year. Thanks for all the great information on your channel.

[@ryankassel5691]

I just found this channel. I watched a bunch of videos. You make really great content. Everything is well planned, understandable, and objective. I'm looking forward to watching more of your older videos, and seeing them in my subscription feed

That's so kind Ryan! Happy you like it! Let me know what you think of the other videos!

[@notch5473]

Thanks again Rob for this great review!! Apple keeps proving optical heart rate sensors can be über accurate. As an androïd Huawei gt2 user, I'm curious to see how the gt3 works, as Huawei claims their new sensor is 96% accurate compared to a chest strap hrm.

[@steelhunter2010]

Please test the Apple Watch SE for the heart rate accuracy, it's really interesting how it compares to Series 6 and 7

[@GadgetyMV]

Impressive results and as usual a great review, thank you. It's intriguing that Samsung which has been making smartwatches for 8 years hasn't grasped the opportunity to hone their algorithms to the same extent.

Hey Rob, i would really appriciate if you make video about risks of wearing smartwatches 24/7. Does it causd cancer and how much raddiation does it emit. Thanks in advance!

Finally a more detailed review about apple watch 7’s health features! I have always wondered how accurate these are since I wanted one for my mother. Thanks!

[@EE-xw4sb]

Omg! This is the best recommendation I've gotten from youtube! Exactly what ive been looking for an in depth review of these features!

[@drsus0]

Ooooh! Nice new studio I’d love to see if there was an improvement over watch 6. Probably doable just by looking at your previous test results against these.

[@322DOTA2]

main improvement is faster charging.

[@drsus0]

@@322DOTA2 cool… my comment is about sensors and that improvement if any. sounds like the sensors performed slightly better and why I asked the question about comparison from past tests .

[@agiverreviga4592]

@@drsus0 The sensors are the same, if anything - they might have slightly improved their tracking algorithms.

[@weekendwarrior8179]

GS4 updated their heart rate algorithm. Can you run an updated test on that?

[@DaemonViews]

I discovered your reviews and have been watching one video after the other. Very interesting data and a good way of presenting it! As a tip, I would however not show your home and work location.

[@TheQuantifiedScientist]

Hi Peter, thanks! Thanks for the tip, it is a tricky one. I considered showing those locations or not. However, my work location can be found online. My home location is not super specific, and it would decrease the value of the review sometimes if I did not show it. Not sure yet if i'll change things over time, but since it is already out there I expect it is OK.

[@theretheartis]

Having used a number of sleep trackers and now Apple Watch 7, I reached this conclusion. How much sleep is recorded depends on how I wear the watch. I normally sleep on my right side and wear my match on my left wrist. If I swap it to my right wrist, the amount of sleep and it’s quality apparently improves. Similarly if I keep the watch on the right side and sleep on the left, quantity and quality improve. This is perhaps not surprising as the data is based on movement and, for instance, sleeping on my right with the watch on the right restricts movement of that arm. I’m interested to know if anyone else has found the same.

[@Johnnn93]

u earned my subs.... very detailed video with too much effort just to be real and not bias! THANK YOU and GODBLESS YOU!

[@Izya001]

Thank you very much! A fantastic review. I have a series 6 apple watch. I hope it performs very close to the series 7. For sleep tracking, I use the application Autosleep, which provides more insight into sleep patterns. As far as HRV, I use Polar 9 (very similar to Polar 10) and an iPhone application Elite HRV. In the first measurement, you receive a VALUE and a SCORE, depicting how balanced you are, and if you are ready for a harder training or should take it easy ! The value differs from application to application.

[@frankysour]

Thanks for the, as always, awesome review. I'm getting to the conclusions that the ideal wearable recepy for me would be... 90% of my Garmin Fenix 6s, carefully mixed with the apple watch hr sensor/algorithm and maybe a frosting of Fitbit sleep tracking capabilities ... Maybe asking bit too much :D:D Cheers!!

[@stringtheory0]

Fitbit Sense advance health or Apple watch 7 Mainly workout and SpO2 while sleeping which is better? already using Galaxy watch 3, fitbit Versa Kindly help😇

[@bassemal-ansary5867]

[@artistryartistry7239]

Can you please consider discussing one feature when it comes to these sleep trackers, which is really important: it's a huge deal whether or not you have to manually activate the sleep mode, because forgetting to do this, for falling asleep (naps or extreme fatigue) can mean that functionally the device is just not as useful as it could be. Knowing whether one device automatically tracks sleep with zero user intervention is obviously a very important feature to know before purchasing. One other thing is being able to detect naps, which are also very important to track. Some devices are bad at this or don't do it at all. It would be helpful to know that. Thanks! Love the channel :)

[@victer9322]

You're a super start for me. Great work you do!

[@msthaheem]

Hey Rob Please do a review of Amazfit GTR 2e as I'm thinking of buying it and as your review play great importance for buying decision. Thanks

[@kirikset]

Your reviews in terms of accuracy are amazing! It would be great if you could review some of the higher end Garmin devices like forerunner 945 LTE or anything recent with an elevate V4 sensor.

[@TheQuantifiedScientist]

Hi! I do hope to test more Garmin watches. Hopefully Garmin will loan me a few!

[@birraebici]

I also have problem with Garmin watches, the Fenix6 X wrist HR can not pick up sudden change, if you run suddenly, the wrist HR delay to pick up the current HR, this happens to many user, but the older FR 935 seems working much better in this case, Garmin ignore this problem, but I see in this channel many watches fail in HR during weightlifting, I’m thinking this is also because of HR suddenly changes?? I’m not sure, Apple Watch seems to be have better wrist HR accuracy, the problem of Apple Watch is battery life!

[@barbiegirlxoxo]

Hi Rob! I love your videos. Will you be reviewing any of the Amazon Halo products? I’m curious about their sleep tracking ability. Thank you.

[@vishalsubedi5135]

Can you review Amazfit GTR 3 and GTR 3 Pro ? They say they have updated Biosensor 3.0.

[@leimleim]

Why there are few dot samples when comparing with other devices you've tested, such as the Garmin's. In those Garmins the cloud of dots is much more dense

[@vineethsai1575]

Can you do a SPO2 check while in sleep. My apple watch sometimes reports outlier numbers like 60 or 70 SpO2 for maybe one or two times when I am asleep. And No I do not have Sleep apnea. I want to see if I can rely on these measurements

[@rohant]

So I got the series 6 Apple Watch just now after watching many of your videos. I’ve been having a high resting heart rate and I wanted the best I could afford. I was wondering, could you do a heart rate accuracy test with more hand movements such as running or rope skipping? I went for a run for the first time in months and my heart rate shot up to 210, pretty high for a 35 year old guy and I want to know how accurate that might be.

[@MrTwix33]

Awesome content as usual!

[@ColonelLucario]

I bought the Apple Watch Series 6 and it’s really impressive to have all those sensors in a so tiny device I’m learning things like my heart rate that seems to be a bit high sometimes but I don’t think it’s alarming (for several hours my heartbeat was approx. 100bpm) And when I took an ECG it say that I have a high heart rate… but it’s down now to 70-80bpm so that’s why I say I don’t think it’s alarming Anyway seeing your graphs that are really detailed I would like to know how you get all the data of the Watch and how you translate that into graphs like you show in your videos

[@jorgeibanez4302]

Great video . Please Could you review the use of the oximeter app in the watch during sleep.

[@theunknownsamurai7426]

How would you compare the Apple series 7 to the whoop 4 as a general health monitoring device (sleep,daily activity and gym training). That includes the app, it's functionality and the algorithm. I presently own a whoop 4. My membership is coming to an end, so I'm thinking about getting a apple instead.

[@-3td4rtgaeas]

How do you use the polar chest strap to measure HRV? Is there an app you connect it to?

[@dvyio]

I wonder if the deviations and blips in the GPS signal could be explained by tall buildings in the immediate vicinity causing the signals to bounce around. It'd be interesting if you could get height data for the buildings along your route and see if the blips correlate to building height.

[@kirkydaturkey]

If you personally Compare Apple Watch 7 vs Garmin Venu 2, which can you recommend? I use Apple watch 4 years and I am considering Garmin watch for better sport tracking and longer battery life. But I am afraid to leave AW after 4 years.

[@francobellomo9979]

Hi, the Venu 2 is really no better than the apple watch 7 for various reasons, the Venu 2 really is an extremely basic sports watch, it doesn't have the performance features of the Forerunner / Fenix. It only has Body Battery and sports modes (it does not matter how many it has, they all do the same ...) With the Apple Watch you can install Athlytic which is a great sports application, it has many functions to see your sports performance, sleep, recovery, etc.

@@schubertepaulausa yes i understand but there is the Series SE for the budget and the S6 that could be found for much less than the apple price But personally even if Apple Watch is more expensive compared the others brands I prefer stability, performance and reliability over price and plastic/cheap design and less precise sensors We are talking about a watch that gonna monitor your health and notify you if something is wrong

[@schubertepaulausa]

@@ColonelLucario I also took a look in the Galaxy Watches in Brazil. I was kinda considering as an option, but the price is also high and people say that in the moment that we drop it gets broken easily.. 0 durability, while we still see people selling old apple watches in the market with a good price Btw: the xiaomis and its sensors are real shit, the price is low but how would we believe on fake data about ourselves? Can you imagine how many people are being deceived for it? And believing in all numbers the watch delivers :/ So far apple watch is the most reliable at the moment

Great video. Quick question to the community here - I had AW Series 6 and now 7, and with both I experienced the same issue- in between my workouts the HR greys out and comes back to life sometimes after seconds or minutes. I tried wearing on left and right wrist, no change. I wear it snugged and the sensor is clean. I never had this issue with my Garmin Fenix 6. Do you guys also face this or is it just me? Thank you
