Withings Scanwatch Horizon: Scientific Test!🧪 (Heart Rate, Sleep, SpO2)

[@liu408]

I love that when KZbinrs that are audience friendly and make timestamps for their audience. This makes it so much easier for the audience to get the information they need without spending unnecessary time going over info they don't need.

[@pavolholic6873]

HI Man, are you planning to test new Withings Nova Scanwatch ? Is Withing planning to add NFC and glucose monitoring to smartwatches. Thanks a lot... btw: best real data video on these products.

[@Xtr3mxD]

I just have to say it again, thx for beeing on youtube! you make my day better everytime I am watching any of your videos!

[@TheQuantifiedScientist]

Thanks so much! Which part of the video did you like best, or what type fo watch are you interested in?☺️

[@Mordotz]

Great review! I currently have the Steel HR and I was considering switching to the Scanwatch later, but would this Scanwatch Horizon be a better choice of the 2 when its available for me to purschase? Withings whole scheme have caught me on the simplistic watch-like design while having great battery life!

[@marcobono3619]

Hi Rob I'm Italian, you speak very fast for me, but your sympathy is contagious..TOP

[@fairbanksbrian]

It's nice to see Withings finally offer a watch that one can read the time on in a quick glance. Their other watches have such slender low contrast hands that they are annoying and difficult to read. It seems like a lot of extra money to pay just to get a version that reads as easy as a $30 Timex.

[@sheriffdan316]

I wish it would show the seconds

[@Betancourtdm]

Finally came out in the US. Been waiting for this one, its a beauty!

[@nikhilgaikwad8014]

Can you please also make a list/report of top five accurate watches? It should include following columns : device name |step count accuracy |heart rate accuracy |.... All sensor accuracy.... |NET ACCURACY SCORE. It will be a easy choice to decide. And later you can create your own hybrid metric to summarise the accuracy. Please redirect me to it if you have already created similar report Keep up good work!

[@enrikomulawarman7617]

Noo. No chart. We are Soo sorry

[@enrikomulawarman7617]

This guy is trying to help us but its confused us more. He's not give us a conclusion which one is what, people are crying on a chart of whose the best. He give us ton of useless review, and you have to watch every his video to know what watch are the best in heart rate monitoring which is not easy, but after viewing lots of it, I forgot and confused.

[@mussabgasmelseed5079]

He has list watch rank according to certain feature ex. Heart rate sleep he rank best for each catogry which he mentions at last few minutes for each video cause no watch is complete or excel in all side ex some watch like Apple huawie excellent in heart rate but no great software to extract useful information like garmen thank

[@denodan]

The scanwatch is a great walkers watch, pretty accurate steps and great watch for walkers. As for going to sleep and and waking up, have had no issues. Mine detects going to sleep and waking up accurately and have had mine 3 months and no issues detecting going to sleep and wakeup times. Both scanwatch and Horizon are the same watch, just different designs. If your exercise is walking then the perfect watch. Seems most fitness watches have trouble with biking.

[@alejandroalvarezbenitez7037]

Hi Rob. Your reference for sleep is deem 2, but I checked and was discontinued, what do you recommend? It would be great to have your comments or a video on that.

[@adamosanatolitis5833]

He had me at "I don't wanna waist your time, timestamps are in the description" Liked and subscribed instantly

[@loganrossignol]

It would be great to see follow ups on these products after software updates to see if things improve over time with the same hardware

[@CirclesOfMotion]

You can perform an advanced oxygen saturation test by using hyperventilation and breath-hold sequentially such as in the Wim Hof breathing technique. You can briefly lower your SpO2 down to 50% with it. The overall measurement range can matter in this test, I think.

[@gamesandgoofs]

Great video, thank you for the info! Now that the ScanWatch 2 is out, is there any chance you could test the accuracy of its features as well?

[@mohammadalsaket4181]

Would you compare this one with the new one? Nova 2?

[@thachhuynh]

Can you please review the ScanWatch Nova?

[@jasonwoolley7891]

Hi Rob, A review on the 8 Sleep Pod Pro would be a welcome addition. It tracks your sleep stages, heat rate, and respiration rate while sleeping all without having to wear equipment. Thanks for providing such a great channel for the community!

[@Hardiarm]

Should include the Withings Sleep device in these studies, and see how it compares with the Sleep function on the scan watch.

[@thatkaz]

Thank you so much for making these videos. I tend to do as much research as I can when buying things like this so you are helping me out a lot. I'm curious about the most recent edition. I know that they added temperature readings. Do you think you might be able to review the new one soon?

[@AlTheEngineer]

Very nice video, thank you for this scientific testing! Its refreshing to see content driven by science and actual stats :)

[@williamstevenson2649]

Another believable review. I wouldn't get a a smartwatch without checking TQS, and all his reviews confirm my conclusion that if you're really interested in accurate HR you need an Apple Watch, a chestnut strap or Polar's Verity Sense OHR- so I got an H10 and Verity. Maybe the top Garmin and Polar watches work?

[@realitynightmare]

Your videos are highly valued. Can you put together an ECG compilation. I would like to know which devices are performing best in this area. I don't want to check my ECG and panick for no reason. Also I feel like I don't have much choice. I'm not a fan of companies like fitbit, apple and samsung who all try to lock you into your brand. Lastly what brand has your favourite software for accessing information about the stats

[@MyLifeInTheDesert]

Best looking fitness tracker ever

[@robertjleter]

Please test Huawei GT3 and huawei runner watch

[@jemand8462]

The normal oxygen levels should actually be between 98 and 100%. In hospital, we get a little nervous whenever a patient has a saturation below 97-96 and track it accordingly as this is actually already abnormally low and might caused by obstructed breathing etc. You can see that on the "real" oxymeter.

[@Slipperystick73]

It should be 95% to 100 not 98 to 100 …. That’s what we were taught as Dr…..

[@Anthony-jx6fz]

Hey, love these videos! Is the better measurements on the horizon vs the normal scanwatch in weight lifting simply a software issue fixed by updates or is it because of different sensors that withings might have used? Would love a scanwatch as my apple watch 5 is getting really scratched since I dropped it a few times when taking it off charge (clumsy) and the battery life frankly quite crap, but am also a powerlifter as a hobby. The measurements are a nice bonus so xd. Thanks!

[@omara1561]

Wow. Thank you for putting in such good work. Subscribed!!

[@soumyaranjantripathy8843]

Their deep sleep is the combination of rem and deep. It is written in the app. So your tables need to be somehow adjusted. That's why many times the rem sleep periods are classified as deep sleep.

[@soumyaranjantripathy8843]

@@joeamerican2611 yes I understand. They can not separate rem and deep with their watch so they decided to combine it. Given that, the analysis could have been little fair to them.

[@romanvoronov6623]

[@georgesabikhalil186]

Great video as usual, I wish if you can start testing the ECG

[@amirnazhan]

As expected. I own the 38mm for more than a year now. As someone who casually workout, the health tracking is not good. In fact, it is worse than any cheaper smartbands like Xiaomi Mi Band 6. Buy this watch if you like the classic round shape design with good battery life.

[@merom.1248]

Nice video and great details! I am testing the Withings ScanWatch right now and going on day 50. How were you able to get the ScanWatch Horizon model so quickly before anyone else...? Did Withings send you the watch for free?

[@Treppiede]

Rob, I enjoy your work. I have an Oura Gen.2, Gen.3, Fenix 6X Pro and EverSleep devices. The Oura Gen.3 and Fenix are my daily drivers. Happy to provide data, if it helps with your evaluations.

[@PeterHerget]

I have the Fenix 6X and I really, really, really wish it tracked naps. I often feel the Fenix, and other Garmins, are less accurate than Withings or Fitbit.

[@Treppiede]

I agree, it would be a nice feature. The Oura ring does track naps, it's pretty neat to see the nap appear on your daily dashboard when you wake up and refresh.

[@gregwillden6181]

[@beatmoser1631]

Hi Rob Love your channel and methods. I bought this watch, it is beautyful. However, on the crosstrainer it's close to useless showing 96 bpm instead of 138 bpm measured with the HFC 10. As no external heart rate monitors can be attached, this issue can't be fixed. Further, the data can't be easily be exported (only via zip - download resulting in huge json files). Verdict: useless even for moderate users like myself. I will have to go back to an (ugly) Garmin, since they have resolved both issues!

[@CarLifeUK]

does it have GPS ?

[@sanketdoshi9974]

[@BEHNAM8011]

I sensed a bit of a confirmation bias throughout this video. The accuracy results presented are underwhelming in my opinion and do not justify the overall positive sentiment. It is a good looking watch though.

[@michaeljoseph7160]

Does this watch have flight mode activation? And can it still perform checks while in flight mode ? Thanks

[@CliffR]

How is Withings so good at sleep data with their under the mattress device, but horrible with the watch? They should be able to use the same methods of calculation. Since there is little movement during sleep I wouldn't expect the sensors to be drastically different in their abilities to detect

[@bigbadboogie6842]

So how about sleep apnea and ecg? Kind of the big selling point?

[@romanvoronov6623]

they don't share the SPO2 sleep data. I feel like it doesn't measure frequently enought to catch any apnea. And the ECG only tells you whether you are dead/alive, while everything inbetween is 'inconclusive'

[@denodan]

If you want a runners watch, then it's Garmin. If you want a walkers watch and this is your exercise routine, the the scanwatch as its one of the more accurate step tracking watches. The HR Sport was rubbish, but withings have really upped their game with the scanwatch and Horizon, miles better in every way than the HR sport

[@heirrose1606]

Wish they made them without the word "Withings" advertisement label on the face. I hate forced labels using me as a billboard.

[@LittleFullLotaSap]

I want that watch, in blue, so bad!

[@LittleFullLotaSap]

I do wish the sleep tracking wasn't so terrible. Scanwatch gjves me over 3hrs of deep sleep and 59 nights with the Dreem 2 showed an avg of 57min. It also is not good at detecting wake ups throughout the night.

[@romanvoronov6623]

After half a month of ownining it: 1) They don't show you a plot of SPO2, even if you set it to measure all night long. The Sleep O2 monitoring is really one of their selling points with the long battery life due to with you give up the smart-watch features. But no, they just give you OK/Not OK type of measurement for the entire night; 2) I woke up, took an ECG and went back to sleep... Yet, despite me manually pushing and holding a button on the watch for 30secs, their algorithm still did not catch the awakening and considered it to be non-interrupted sleep... 🤦‍♂ 3) The ECG basically tells you whether you are dying or not. Anything inbetween is "inconclusive". So, overall, you mostly just have the mediocre (according to Rob's study) heart rate monitor on a classic-looking regular dumb watch for $500. I am considering returning it.

[@mussabgasmelseed5079]

😂😄😂 i read it is ok for statistic monitoring not for exercise but according to ur experience even for statistic is not accurate enough

[@romanvoronov6623]

[@Nod4750]

The watch is recommended by Cardiologists for detection of atrial fibrillation and that’s the main reason a lot of people buy it.

[@romanvoronov6623]

I will add to this that I measured SPO2 on a trans-atlantic flight at different elevatations, and it barely showed any decrease at all: it went from 98% on the ground to something like 95-96% at the highest altitude of the flight (which is probably within its accuracy uncertainty bounds anyways).

depends what you are looking for to be tracked. all models do have their advantages and disadvantages. you can buy the apple (older model) - where you get good heart rate monitoring e.g. - i owned many brands started with moto 360.....during the years i noticed that i do not like charging them every single day and i also do not like to have a mobile computer on my wrist getting notifications back and forth. used several withings models now - and yes maybe they are not 100% accurate, but i do like to wear them every day and i am getting somekind of tracking on avarage level so that i can compare days/weeks/monthts activities.
