Your videos are good. It is clear you are a genuine scientist and understand data analysis. This video is now over 1 month old. 2 sets of questions--the 2nd set is the most important. A) Is the Scanwatch now available in the US? If not, do you know the ETA? Is FDA approval needed or just good advertising? B) My wife does have known Afib and sleep apnea issues. So "real-time" detection of Afib incidents is important to us. Perhaps every 10 minutes detection is enough given such incidents normally last longer. Tracking periods of sleep apnea are also important. Other watch functions like email notices and news flashes and step tracking are less important to us. So the question is: With health monitoring the main need, what do you recommend between the watch options? These are Scanwatch, Sense, and Apple 4 or later? We can wait a month or two if something significantly better will only be available then--for example the Scanwatch in the US.
Hi there! I ended up buying a wirhings scanwatch based on your reviews and I'm impressed. Only thing I've noticed it that the step count is only a third of that I reach on garmin or fitbit. I think fitbit overestimate but if the 3, garmin seems to me the most accurate with steps and also stairs. I'll go upstairs 12-15 times a day yet scanwatch only ever detects up to 8 times, max. With the health mate app I don't have the bit you show on your videos that says apenic episodes, only breathing disturbances with a graph that has no context other than few, moderate or severe disturbances but not the apenic episodes that yours shows. I've only worn mine for 4 days though so does that feature unlock after a week or more? I enjoy your videos, thanks for the in depth reviews and great content!
As with you, I’d want continuous heart rate monitoring, I feel that is need to track fluctuations. I was wanting to get this watch as I liked the style. I’ve decided to pre-order the sense, I hope you will be reviewing that.
Same here, i was considering the scanwatch and Fitbits sense, but hearing here the hearth rate measuring is not continuous, I’ll go with the sense. Just hope they get the ecg certification in Germany quicker than some others...like Samsung who sold their GWA2 one year ago to us and still no certification for it....
Agreed too. It's crazy to me that they are pulling an Apple and saying 'we won't let users have the option for continuous heart rate because it's not what the company wants'. People are interested in these devices because of the health features, just make 10m scans the default and continuous an option.
Damm these are great reviews I ordered the watch yesterday and can't wait to try it out. I did not like the Apple Watch, it was too annoying, too many notifications, and I love mechanical watches, so I was first sold by the looks and then the software. Thank you for the fantastic coverage.
If you're interested in what I do, find me on Instagram: instagram.com/quantified_scientist/ 👇Amazon Affiliate links, support the channel!👇 geni.us/Ixsd8 For those interested in the sizing. My wrist size is ~16.7cm (just measured it), and I think the 38mm black version I have looks quite good. But it really depends what you are looking for. I made a short video of me wearing the watch: drive.google.com/file/d/1_R3veXfwjMglSEVUg2ogXElpunxLViK1/view?usp=sharing . Hope this helps!
Love your presentations. I am really attracted to this form factor for a watch but what comes up for me is why are these makers still only using the green light for scanning when the combination with the red-infra red light has proven much more accurate, notably with ECG? I have seen this readily available and inexpensive in the Spovan Blade and the V19 smaller watches.
I like my Withing Steel, measures distance accurately but sleep measurement is miserable. The promises of the Scanwatch are very interesting. But I will wait till they are included and confirmed functional.
The Withing Health app is lacking rem sleep analysis. Would be nice if Withing Health App also includes training load accumulation and recovery from training load 24/7. The Withing Health app has beyond this request many other useful features including reporting in an easily understandable format.
Hi Rob, again an interesting video; did you notice any performance improvements as a result of the heart rate tracking as a result of the update that was released a day after your video upload. Version 1471 - September 7th, 2020 Version 1601 - October 16th, 2020
Hallo, thanks for your videos. They are really pushed in terms of comparison and science and I really love that. I have some questions regarding the watch. Can you help? Thanks I am really interested in buying but I have 2 blocking points that are important : 1. The heart rate is wrong several times when you are exercising. The watch detects half the heart-rate and it is a problem for a lot of people as I see. So, just to have a number, let's put it at 30% wrong in the heart-rate. 2. The sleep detection is 25% wrong in your test. My questions are: 3. Did the Withings crew mention and of these points (1&2) in the Q&A? 4. Do I need to wear the watch very close strapped on my wrist (like it does not move at all) during normal wear and also exercise? (I like to wear watches a little less tight, if not, I will sweat on my wrist and it's not a nice feeling) 5. For me the heart rate and sleep detecting are important factors. Do you recommend buying the watch knowing that the heart rate and sleep detection are not even close to 90% accuracy? 6. When you exercised, did you use auto-detection or set it yourself in exercise mode? 7. What is your oppinion, could they really improve these 2 issues with just a software update? Danke schön!
Hi everyone I posted earlier about how wonderfully accurate this watch has been for me personally, then today it went mental - heart rate all over the place. I have discovered something interesting if you hold the button in for seconds and you will get the firmware version. Press it a few more times until you reach factory reset. Then scroll and you will find Cache. If you clear the cache, (do not factory reset) the heart rate accuracy returns to being perfect. Mine was reading too low then too high, measured 110 while sitting. clearing the cache totally fixes the issues. I can only assume this is a software glitch which results in erroneous data building up in the watch and messing with results. Very interesting, this would go to say the hardware records perfectly but the software has glitches in. Maybe the Scientist on this thing can try it himself and see if he gets the same results as I have. This would mean this is a problem that 100% can be fixed with a software update. I recon this watch was rushed to launch under covid conditions, the french were not working and the watches software has some way to go before it catches up with the hardware on offer.
nice work !!, great to find a you-tube scientific angle on these "health wearables", i have been using the withings cardio scale and bp cuff for yrs and am quite impressed with the hardware and app, but i need more from my "smartwatch" in terms of "smarts", ie., notifications, telephone call acceptance and ability to respond on my wrist-very useful and important for me, as i am a solo practitioner physician in the field, (medical home visits). so i've been back and forth with the samsung active 2-takes calls on wrist, and fitbit ionic-does NOT take calls on wrist, the last 2 yrs and integration with the health mate app for the scale/bp cuff, but trying to have one all-inclusive hardware/software product, (prob asking too much at this time with competition as it is!, and i'm invested in android/google so apple watch is out for now). have you/will you review the fitbit sense/samsung watch-3, and upcoming oppo watch ?, and lastly what would be your rec for an all-inclusive hardware/software health/fitness-smart wearable ??, dan in michigan-usa
Hi Dan! Thanks for sharing your story! So, I have the Withings Cardo and Withings BP too, and they seem to work quite well :-D . I do plan to review the Fitbit Sense, very excited to see it. I might test the Samsung Watch 3 too, but I need to see if my budget allows buying multiple products. For now, I must say I am a fan of my Fitbit Charge 4, since it has a good price-feature ratio and tracks sleep quite well ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NYRq4ahPJ2c.html ). But of course the new FitBit Sense seems to beat it if we look at the features. I need to check though how limited the data is when you have FitBit premium vs when you don't have premium, because that could be a turnoff for any people. I must also admit that I use fewer of the Smart-features than you do (e.g. text on the watch just distract me from work), so I don't really use those. For me the tracking is most important. Once I have tested the FitBit sense I will be able to say more, so stay tuned.
@@TheQuantifiedScientist thx for the response QS !, i understand my "smart" features needs are beyond most but...c'est la vie,....i will await your future reviews with great anticipation !, dan
Awesome! Thank you for putting this up, it makes deciding for /against the Scanwatch a lot easier! Looking forward to more science nerdery from you concerning fitness trackers of all kinds. Should you ever want to compare epigenetic results, send me a message ;-)
Thanks Mathias! I have some Paxgene tubes with blood samples in which I might want to measure ATACseq at some point. I'll keep you posted :-P . Have a great day!
Hi Rob, thank you for your concise and informative videos. I'm in the market for a smartwatch with good sleep tracking and SPO2. Have you tried out any of the Garmin Vivoactive line at all, as I've been looking at Vivoactive 4 since I play golf. Anyway keep up the great content! Prost!
If you want good sleep tracking you better forget the Garmin watches.. I have long experience about smartwatches and oura ring, and I can tell that Garmin gives you too much sleep, like 30-50min more than oura or Apple Watch example.
with the Steel HR model, the recording of your workout stops after 6 hours. For example, if you do a longer walk, it will stop after 6 hours. Pretty annoying if you want to monitor this workout.
Hi Rob, thank you for your videos! I wanted to ask you a personal opinion because my dad suffers from AFib and also have sleep apnea, do you think the Withings could be a good option for him? (Price/ accuracy) or maybe I should pay for the apple watch which has more functions compare to this one and also has included the ECG/blood oxygen feature? If you have any other recommendations I am open! Thank you so much!!
Hi Rob, your videos are really well done and super informative. Could you do a review with the apple watch too and compare both of the watches to the ecg and heart rate please. As the apple watch is market leader at the moment, it would be very interesting to compare the both.
@@TheQuantifiedScientist Please do also a sleep tracking accuracy for Apple watch. it would also be cool to compare apple watch 5 vs 6. I have sleep problems and sleep tracking is my main concern.
Hi Garluis! Do you mean specifically for the ScanWatch? I would have to see how to test this. I could imagine cycling certain wattages on my home trainer, and seeing if this correlates. Or do you have any ideas?
@@TheQuantifiedScientist I realize this is not that easy, but maybe in the future in the same way you compare sleep tracking against medical tests, you could compare calories burned against metabolic gas analysis. Any device, not just the scanwatch. The info would be incredible, because we would be able to tell which tracker is best tracking sleep, Wich best at calorie tracking and maybe a best overall.
Thank you, very useful. Did they mention if they are going to fix the activity tracking and heart measurement inaccuracy during sport sessions and when? I have already returned mine because of that but may return in the future if that is fixed. Will wait for your fitbit sense review before deciding. Thanks!
Hi Alex! Thanks for your message. They did not mention the HR problems at all. I asked, but that question was not selected. So I guess we just wait and see. Have a great day!
Great video (once again)! :) And I have a not-so-scientific question: I'm probably gonna get myself the Scanwatch as soon as it comes out but I don't know which size to get - To me, the smaller one looks better (because of the thinner frame) but I'm afraid that it might be mainly for women and look weird on men as 38mm is really small. Afaik you have the smaller version - does it look "normal" on a man's wrist or does it look too small?
I've a thick manly wrist, and the 38mm white looks FANTASTIC. I'm just gutted the feature et just isn't there, so sent mine back for refund. The cheapest fitbit can do continuous HR ffs.
Hi Niklas! If you look at the top comment, I posted a quick video there showing what it looks like on my wrist, including my wrist measurement. Hope that helps!
Thanks a lot for this video. I prefer design of the 38mm version but I don't know if it could be too small on my wrist. Because I always wear watches between 40 and 44mm. I have a small wrist, between 16,5 and 17 cm. What do you think about that?
Hi! My wrist size is ~16.7cm (just measured it), and I think it looks quite good. But it really depends what you are looking for. I made a short video of me wearing the watch: drive.google.com/file/d/1_R3veXfwjMglSEVUg2ogXElpunxLViK1/view?usp=sharing . Hope this helps!
With this video now approximately 2 weeks old, has anyone seen an update regarding the REM sleep addition? That's the only thing withholding me from buying..
Hi Justin! I have seen no other updates. They said they are "working on it", but I suspect that it will take a few months at least, based on the fact that they started a new initiative to improve it across all their devices. But, this is just an educated guess, and I am happy to be corrected by someone with newer intel ;-)
@@TheQuantifiedScientist I contacted Withings regarding REM sleep. This is what they replied after all: "I can confirm to you that the ScanWatch is not yet capable to track your REM sleep data. However, sleep apnea detection will be added this coming quarter 1 of 2021 so it is possible that it will also be added as a feature at that time."
Great video, Did you ask about the problem un the bps measurements with values of half the real ones during your training sessions, if they were aware and if they are going to release a fix?
Hi Mariano! I asked them, but unfortunately they did not answer it. There were too many questions to answer all of them, and they did not pick this one.
Hi, wondering if you could help a chap out. I have many health issues, Pass out climbing stairs etc, So the NHS units are all busted. Im needing to track everything, I wasn't aware of this scan watch and just bought the move ECG last week, Also went with the blood pressure, I am missing body temperature, Also i wear the Honor 5 band, which is the most accurate with sleep and more importantly naps, But i'm also in the need of GPS and fall monitor , Say i fall and no movement within x amount of seconds or minutes etc, it would auto send SOS , Id be able to go out, Well after this lockdown, As im buying all sorts of bands trying to find the right unit.. So i was kinda wondering if there's a watch or a band out there that can medically do it all in one that you could recommend., . I find the sleep pattern is way way off on this withings. Is there anything you or maybe your members could point me towards i'd be really appreciated . Cheers Mark G.
Hi Mark, thanks for your message! Sorry to hear about your problems, hope it gets better soon. Let me start off by saying I am not a medical professional, so my comments are just based on my own experience as a user of devices. I am not sure if there is an "all-in-one" device for what you want. The Fitbit Sense that is coming out soon has: sleep monitoring, temperature deviations (at night), SpO2 (at night), ECG (starting this October/Nov), and even EDA (user activated) for stress measurements. In my experience Fitbits are quite good at sleep tracking. Now, fall detection seems quite vital, and I could imagine having a dedicated device, I it is think part of the Apple Watch, though I am not 100% sure. The new Apple Watch was just announced and will have ECG, SpO2 and dedicated sleep tracking, though I still have to study the details. Hope this helps! Cheers, Rob
Great review, finally someone that knows what their doing! btw, can you/anyone in the comments section link to a retailer that has the watch and can ship to the US? Thank you!
Hi Sandrodjay! Thanks for you comment. I don't remember it coming up. I am also unsure if the PPG in the watch is of sufficient quality to do this (given that the HR measurement is already not too good). Maybe someone else also has some thoughts on this?
Hi all, Rob mentioned in this video that continuous heart rate is not in line with the philosophy of this watch. Could anyone please recommend me a good consumer device with continuous heart rate measurement that one can easily see all the time (on the wrist or on the smartphone)? I'm interested in using this as a biofeedback to detect changes at the very onset. 100% accuracy is not that important, it's not for weight lifting or other sports which may impact the accuracy, and I'm interested in real-time trends more than in precise numbers. Thank you very much in advance!
Great video as always! Looking forward to the new features. Do you have a recording of the webinar? I didn't receive a invitation even tho I clicked yes in the form they sent
Hi Tristan! I tried to record it on my Mac, but the audio would not pipe back to my headphones, so I had to stop it. I do have most of it recorded by pointing my camera at the screen (though some part are missing when my SD card ran out of space). Would that be of any help? Have a great day!
@@TheQuantifiedScientist yeah it would be nice if you could upload it somehow. I would be really interested in watching a bit. Withings told me they don't have a recording at all :(
This is a good watch, but I had to cancel my purchase due it doesn’t have the Blood Pressure Monitor, any idea if they going to include this in the watch. Then I’ll buy it.
What does he mean by "predict REM-sleep" Why would you predict something like REM sleep, or why would a watch predict anything? Maybe predict a heart attack could be possible, in a few years.
Weer dankje wel voor je input, Je doet het echt goed! Stel even vraag in engels. This is my first comment on one of your video's and I came across by sleeptracking. I am now tracking that with whoop because that is one of the functions. But I was currious how accurate this is, do you know a little bit about that? Groetjes vanuit Nederland
Hi Chris! Heel erg bedankt voor je compliment! I recently read a scientific paper about the Whoop strap, and I am planning to make a video about it. Unfortunately, the authors would not share the data with me, which is surprising to me, since we are more and more entering the world of "open science". All I can say is that my first instinct is that the Whoop strap is about as good as the Oura ring, based on that paper. But I will have to do some analyses to know more. Stay tuned! Groetjes uit Wenen
WOW i just want to said that I been using the 38 mm and the 42mm and it's very interesting what I found maybe you can try yourself as I been having problems with the heart rate accuracy as he said in one of his videos and because of that I do try the 42mm myself two times I ordered just to be sure and wow I will say with the 42mm it's more accurate and you don't have the problems been losing Alf of the heart rate when you are doing a exercise .. so I don't know if the 38mm are defective or so but I test two 42mm scanwatch with the last appel watch at home and polar and for what I see the 42mm work very well so will be cool if u can also take a try and tell me what you think.
I wish it had better sports features, nothing fancy but no withings watches contain a lap timer/interval timer which is super annoying. Also the screen should show a second hand as a widget (I’m a paramedic and need a second hand for work)
Hi! I guess a lot of pulse oximeters that measure spo2 through the finger instead of through reflection are more reliable. This technology is probably better developed at this point, so i would trust it better in general. But this is very much a gut feeling, i would have to search through literature to make sure. Have a great day!!
Are any hybrid watches accurate enough for a runner? I really don’t want a clunky techy watch but I do want something accurate with a good battery life!
I found no watch is accurate enough for running. Garmin Forerunner and VivoSport, as well as Fitbit had the same problem as Withings Steel HR for me. Chest strap is the gold standard (and even that can have frequency halving in winter, if your skin is too dry).
Hey Rob, thank you for the transparency! Can you make a video about the withings libra. Hope the scanwatch will be available at 0:00 tonight. I’m very afraid!!!
Thanks for the update. Really found your channel useful. If I can give some feedback, I notice with every cut you tend to rest your facial expressions by starting with a large smile. You have a great smile don't get me wrong but for the sake of the video it always make you feel that the video is restarting.
Hi Corinna, thanks for the feedback. But what did you think of the content? I am indeed not a native English speaker, but I expect most people understand what I am saying despite this "limitation". And, yes, I am a fast talker, but there is always the options of playing a video at half speed, if the speed at which the information is presented is too fast ;-) . Enjoy your day! ( Take it slow ;-) )
@@TheQuantifiedScientist I'm a native speaker and I genuinely thought that your English and pronunciation was great. In fact, when you mentioned at the start that you're from Austria, I though to myself, "wow this guy speaks great English even though it's not his first language." And then I came down to the comments and saw this. I would suggest not having background music in your videos, because your videos are speech heavy (as they should be) that the music just interferes and makes it more difficult to hear what you're saying. I also want to say: keep smiling! It seems like a conscious thing that you do, and it's noticeable and commendable.
