This channel is great, I wish we could get more reviewers doing actually data-driven tests rather than random opinions, specially for products like these.
Great review. Message to Samsung. Focus on being great at two or three things rather than mediocre at ten. If they can't get the GPS or heart rate tracking spot on, they have no reason to focus on all these fringe features.
I wonder can you redo these tests in a few months or so? To see if it can improve over time with software updates. Not only for this, but other smartwatches too. Great video as always
Bumping this. I'd love to see if they've improved any of this, and if you can do ongoing calibrations to continue to improve blood pressure readings or it's only one time.
Hey, thank you for all the videos. Finally we can have an objective analysis of this watches features. I wish you could sometime analize a Ticwatch Pro 3. Thanks for all the effort.
great review !!! you should check the other aspects as well as the heart rate now after the new software update sems to be really good in the gym and other exercises. for sleep i notices some changes
Would be nice to see correlation data during or after exercise, when blood pressure is much higher. Also, would calibration with data after exercise improve overall accuracy or not? Please use the same scale and range for both axis.
The automated blood pressure machines are notoriously unreliable. If I'm ever concerned enough about a patient's blood pressure, I want to get a manual check. Is there any way you can retest this maybe with fewer data points but by using a manual stethoscope and sphygmomanometer? I think you'll get much more accurate results that way and get a much more reliable reference.
Second that. I also would like to see measurements after/during a workout where blood pressure is significantly higher. Would not hurt to have another reference device and see how much they differ from one another. Also there are differences between arms anyway and both deviced used in the video use diffent locations for the measurement. There are a lot of sources for difference between the devices. If the measurements of both or more devices are within a ~10-15mmHg difference of each other across a higher range of pressure levels I would see that as absolutely acceptable.
Hey, great surprise to find one of your vids on a Wednesday. Thanks a lot! Any chance you do a review of the sleep detection in the Coros Apex watch you reviewed the other day?
Yes, I thought I'd get this out before Black Friday, in case people with Blood Pressure issues were planning to spend a significant amount of money on the watch. At the moment I have no Coros devices planned in my near-future videos. At the moment I am testing the Amazfit GTR3, Huawei Watch 3, Amazfit Neo, Fitbit Charge 5 and a few others already. Of course also the new Oura Ring 3 and Whoop 4.0 when they arrive
Thank you for another great video As you know the mechanism to measure blood pressure is pressing on an artery to be occluded and then releasing the pressure gradually until blood flow overcome the artery resistance. This point is Systolic blood pressure. I haven’t seen yet a medical device to measure blood pressure without pressing & depressing an arterial line. 🙏🙏🌺🌺🌺🌺🙏🙏
Then you are not familiar with art-lines nor laser doppler flowmetery. Both are medical devices which can measure blood pressure even more accurately - and not via a cuff.
@@mitchelltanner6306 I know about doppler ultrasound not laser , measuring RBCs flow speed and directional of blood flow through cardiac valves. But I dont know about laser role in BP!! calculating-measuring
Yes, but algorithms cannot fully compensate for peripheral resistance or (for example) interference from venous return when measuring the pressure wave - leaving ultrasound somewhat less accurate than the cuff or laser - but of course great for pressure changes and flow for the cardiologist.
Good video, but one problem is that most (perhaps all) automatic blood pressure cuffs slightly overestimate blood pressure (including the Omron device). The gold standard for measuring blood pressure is a manual inflatable cuff & stethoscope (you can learn this skill quite quickly). I'd also love to get testing results for the Akkia blood pressure device that has now been approved in in Europe.
any possibility to re-test the heart rate monitor during workout? the recent JA update with new algorithm solved heart rate drop out for me and has been very consistently monitoring the heart rate for entire workout, but I really wanted to know if it's correct or just filler data. Thanks!
@@namnta I will buy it even though I know there are some issues with it. Like if you want the best, go for an Apple watch but I don't have an iPhone and am not willing to shell out a lot for both the phone and watch so I'm just gonna make some compromise and settle with the galaxy. Like I have the thought that tech keeps updating so even the best of today will be obsolete in the near future.
You could get a polar h10 chest strap for yourself to test it 😉 😝 honestly I have a fitbit device and this is why I'm waiting on pulling the trigger for either this or a sense 2 I want a definitive improvement (similar to Apple watch) before pulling the trigger on a new smart watch.
@@namnta yes no more hr tracking issues, it used to drop out w intense hand movements, but after the update it never dropped out. but i'd like to see if the data still reflect accurately as it used to
You just need to keep calibrating the watch for every measure, and you're good to go :) Nice video, thanks, I was wondering, and understand why the blood pressure was not released everywhere.
Just found your channel, and finished watching the full review, then found out this. This is one of the best reviews I've ever seen about the watch. Is there any chance that you'll review the health sensors again? There has been some updates, it seems. Maybe into the near future.
Great, thank you for following up the previous review. So it's getting better, but still not good enough. The Galaxy Watch 4 seems to be a continuous development project.
Although I appreciate the data analysis, I have some doubts concerning metrology. I have an Omron bpm and find it somewhat inconsistent between sequential measurements. So I wonder how much of the variation (R2) is caused by the reference? On a different topic, how does the sensor work? Does it have a manifold inside the band?
I have a two omron blood pressure cuffs, one wrist and one arm, and I find with those readings can vary widely from reading to reading as well. This is an important methodological question.
I loooove your videos! This is the most informative channel I've found when looking for detailed information about fitness bands. Could you pleeeease do an acurracy ranking with the top 10 fitness bands 2021??? From now on I will only watch your videos before buying any more fitness bands ever and ignore the other videos out there because you are the only one who tests the real accuracy of every important aspect of these fitness bands.
Great video as always. I recommend to use a sphygmomanometer as a reference blood pressure monitor. For me I have issues with my blood pressure and my certified digital blood pressure monitor rarely gave me accurate measurements while it was okey with other people. Maybe because I have some irregular heart beats but nevertheless using sphygmomanometer is better. Also I noticed it gave you a reading of 136 over 65 and I am quite sure that was a bogus reading in terms of diastolic reading
You are a saint... It's so hard to find good info on this stuff and this video was amazing. I'm going to watch your full review now because I would have bought this watch for blood pressure alone but since it seems like that's not so amazing I'm on the fence. Thank you for laying it out so scientifically but also so easy to access
Were you able to gather any insight into what might make a calibration session most accurate? I also wonder why you don't take multiple measurements at each calibration? I only have an end user knowledge of how these features work, which is to say I really don't know at all! But I'd think you'd get greater accuracy if samsung had you test a few times, starting at rest and increasing blood pressure through activity and returning to rest?
How do you account during the turn of the century 1900 we cook with fat and consume huge amount of meat but virtually no cases of a heart attacks or strokes? Eating animal fat does not make you fat. Our problem started during the 1970s when we removed animal fat and substituted sugar, seed oil and highly processed carbs.
You truly are the best reviewer of these watches health features! 😊 Your results probably corresponding with why Samsung could not release the BP because it has not past test.
I like your approach to reviewing devices, but my Watch 4 blood pressure monitor is very accurate. I do think Samsung made improvements over time with firmware. The main issue I have is the GPS on the watch can be inaccurate.
How did you measure your blood pressure? Did you do it while your blood pressure was low high or normal? My dad did his while his was low and now all of the values are quite low.
When they said the watch could measure blood pressure I started researching how they do it. It seems they correlate blood pressure with heart rate, so the higher your bpm the higher your blood pressure. But this is not always true, I have a condition which makes me have higher blood pressure despite being fit and young. Such a disappointment, for watch and a huge THANK YOU for this video!
I'm not sure if I'm missing something, but aren't those little BP monitors also known to be innacurate? Shouldn't the comparison have been with a medical/ mercury BP monitor?
Can you please enter the BP monitoring space too - their comparision, analysis. Cant find any quantitative analysis videos for BP monitoring out there. Ex: Withings BPM connect, OMRON device series etc.
If values are too low. Bias the manual calibration values slightly higher, to split the +/- variance. Problem solved. Measuring blood pressure is fickle at the best of times.
What is your personal opinion on watches that can measure stress ? Are they reliable? I'd like to buy a watch that can measure my sleep patterns..something like fitbit charge 4 or 5...but I'm also interested in watches that say they can measure stress levels ? I'm someone who suffers from anxiety and is under a lot of stress. That's the primarily reason, I also tend to grind my teeth and have facial pain and it usually goes off at night time.
Love all your videos!! I'm really curious about the Amazon Halo sleep stuff as well. I wish more companies had a screenless band like the Halo and Whoop. A Fitbit that looks like a simple strap would be perfect for me.
Why not just calibrate once a week? It looks like calibration lasts roughly a week to produce accurate readings. The point of the BP function of the watch is to give a rough reading while you're away from home so you don't have to travel with a cuff.
Hello, incredible video. Would you be able to make similar video of the Huawei Watch D ?, as it seems it has a small pump which could actually provide accurate readings. Thanks for sharing your knowledge.🙂
Lovely review! Any intentions on reviewing Amazfit GTR 3 PRO? It seems they have improved heart rate monitoring A LOT! I'll only believe after you test it though hahahaha
Hi, Rob, could you please test AsusViwatch BP/SP or their new version "5"? I have VivoWatch BP and found that its blood pressure measurement is quite close to cuff machine. It also measures continuously, which Galaxy Watch don't. Keep up your great work!!!
Would be great to see some color separation or different symbols for the plot points on the systolic and diastolic charts so we could see separation of watch vs cuff.
Another great review, and not only because it confirms what seemed obvious beforehand: wrist based BP measurements are rubbish. Fortunately, we now have access to a man who actually finds out! Hoping for a review of the Huawei GT3!
Hi, many thanks for the video. I need your advice please. I bought Galaxy watch 5 mainly for checking BP but I am getting very inconsistent results. Sometimes it's lot higher and other times much lower. Almost always with a difference of 15 points in Systolic and 10 points in Diastolic. Also what's more worrying is that sometimes it gives exactly the same reading as previously taken reading. Did you come across such problems? and anything you could suggest to improve the readings would be greatly appreciated. Thanks again
Please test huawei watch D. They have bp monitoring too its their first BP watch. Also, there's this Chinese watch wayneed yingzhi smart watch that has BP, uric acid and blood sugar. I want to hear your side so that I can buy for my elderly father. I'm always away and watches with those features help him a lot
Aug 5 2023 I just called SAMSUNG TECH because my BLOOD PRESSURE feature on Samsung watch 5 is missing. The tech tried to help me reinstall it but then found with the last Samsung UPDATE the feature was REMOVED for blood pressure monitoring by the FDA? Strange because I still ahave that feature on a different brand (cheaper) watch that I own.
Any chance of the amazfit gtr 3 pro being reviewed? One claim is that this generation Amazfit closely matches the Polar H10 in average heart rate accuracy. With Notify for Amazfit the HR and oximetry can supposedly run 24/7 with HR sampling every second.
What the hell could be the explanation for that the values were not correlating with calibration, but were slightly correlated without calibration? In the end the conclusion should be not to calibrate, but know that values are systematically lower.
Isn't the watch and your dedicated BP cuff two different methods of measurement? Using the BP cuff, isn't this use of oscillation detection vs. IR detection from the watch? I've used a large number of automatic devices and have taken hundreds of not thousands of BPs only 34 year career as a medic. Even auscultation measurements from different people normal results in varying degrees of difference from 2-8mm of differing personal senses. Placing a air bladder in position must be consistent and concise and pressure to be accurate. Did you have your automatic BP cuff calibrated? Was the Sphygmomanometer gauge itself calibrated and in the window of use, that little square box at the bottom of the gauge, that the location of the needle sits in? The only true way is to have lab calibrated devices to test out your results. This meaning that a professional hospital grade automatic sphygmomanometer be used in your testing. To be even more precise use arterial catheterization. I'm very for using your results to make determinations in these gagets but right now your measuring a gaget with another gaget that may or may not be in calibration. Also, it's never a good idea to measure your own BP, in a subjective setting while trying to obtain a objective outcome.
There is a very cheap watch, the Y68 that has blood pressure, in another video was very close to an sphygmomanometer, you should do a video for that watch
Hello! Huawei gt2 or gt2 pro, Which watch will give more accurate information? What is the difference between these two clocks in providing accurate information? I gave you a message on Instagram. But, I haven't got any answer yet. Please answer my question.
one problem with the samsung range is. the watches dont allow data above 160 / 120. as someone with high BP i find it unacceptable that it limits its readings. its the same with the ECG. i have a 5 year old N58 watch that is spot on for £30 without limiting the readings. sadly took damage at work. WHY CANT SAMSUNG DO THE SAME
As a data scientist, this channel is definitely GOLD!
Hell yeah!
I noticed that hispanics are really into the data analysis thing.
@@stb3987 Well, just have a look at their diet. LOL!!!!!!
You arent a scientist. You study numbers. Its called math.
I have the galaxy watch 4 but doesn't come with bp monitor app. Which do you recommend?
This channel is great, I wish we could get more reviewers doing actually data-driven tests rather than random opinions, specially for products like these.
This is exactly the type of review I was looking for. Accurate reporting on methodology and results. Thank you!
Great review. Message to Samsung. Focus on being great at two or three things rather than mediocre at ten. If they can't get the GPS or heart rate tracking spot on, they have no reason to focus on all these fringe features.

Hi Andre, I am currently testing it
Great job as always!
Great video! Did you make one on the Galaxy Watch 6 too?
....this means that the Galaxy Watch 4 us not worth its weight in dollars!😂
For calibration, probably you can do with two sitting measurements and one after exercise (increasing BP) to increase accuracy.

To be even more precise use arterial catheterization. I'm very for using your results to make determinations in these gagets but right now your measuring a gaget with another gaget that may or may not be in calibration. Also, it's never a good idea to measure your own BP, in a subjective setting while trying to obtain a objective outcome.
Hi, is there possibility to test for oppo watch in near future?
Thanks.
Should not this be measured on left hand?
Mind you its only as accurate as your reference BP monitor, which itself is not medical grade or as accurate as medical grade monitors
There is a very cheap watch, the Y68 that has blood pressure, in another video was very close to an sphygmomanometer, you should do a video for that watch
Hello! Huawei gt2 or gt2 pro, Which watch will give more accurate information? What is the difference between these two clocks in providing accurate information? I gave you a message on Instagram. But, I haven't got any answer yet. Please answer my question.
How do you know whether the Omron is accurate?
Now that the galaxy watch 6 is out, have there been any improvements in the BP feature?
any chane you could do the Aktiia blood pressure device ?
one problem with the samsung range is.
the watches dont allow data above 160 / 120. as someone with high BP i find it unacceptable that it limits its readings. its the same with the ECG.
i have a 5 year old N58 watch that is spot on for £30 without limiting the readings. sadly took damage at work.
WHY CANT SAMSUNG DO THE SAME
