Nice and informative video, as usual. I would be curious to see same level of analysis over one of those "no brand" devices that claim to do... Everything! Couple of names are the "FIYPO E80" or "BAKEEY E66". These claim to do blood pressure, ECG (and relevant AI analysis), sp02, body temperature... I know these must be considered gimmicks but could not resist and got myself a E66 for 15euro... All measures do appear to be in the right ballpark but... That could be a easy thing when you have actually all "normal" values 😂 This said, i do understand this would imply a lot of work over, basically, a toy, but still remain curious as to how these actually work

Yeah! It's been almost two years since Rob made this video. A LOT of updates since then... Maybe some features improved!

Have been waiting for this! Hope Samsung sees this and responds with updates!

I think a probably reason why the watch misses the heart peaks could be the sensors sampling frequency which might be to low to detect more of the peaks. But the higher sampling freq. would cause more battery consumption. Maybe they do some interpolation, that could explain why the signals signature is detected good and only the peaks are not right in amplitude

We should donate to this guy some of the money we save thanks to his honest reviews.

I don't usually leave comments on youtube vidéos but I gotta your reviews are a work of art, a truly scientific unbiased data that actually provide us viewers with the answers we seek. I cannot to thank you enough for the dedicated and detailed hard work you've done, you've got a new subscriber/fan in me for sure and I can already predict a continuous growth and success of your channel. With all of that being said I do wish you reviewed the rest of the sensors, namely the ECG and body composition. Another wish of mine is a quick look of the results after a major software update like the one recently released by Samsung. Until then I am gonna go ahead and enjoy the rest of your reviews, keep up the good work. Cheers.

Great effort and presentation. Loved it from start to finish. I didn’t even need you to include a conclusion section because I nearly watched the whole thing. Glad I found your video.

This man is doing a great job in reviewing the accuracy of smart watches. Thank you very much!

Ok I'm gonna stray away from the topic at hand since I'm very thrilled to see statistical stuff being applied in real-life. I've learned statistics last sem but failed to understand its importance. Now I've finally known the importance of ANOVA, regression,etc. All thanks to you! I hope you will continue updating this review several months later after a possible software update that addresses the inaccuracies of the sensors, if possible. Keep up the good work!

First time I've watched your review. Amazing. The sheer quality is amazing. Keep up the amazing content bro.

Incredibly helpful analysis and review! Thank you! First time I've watched one of your videos, but it won't be the last!

FANTASTIC video. It's GOLD. Really appreciate the quality of your analysis and the amount of time you invested in conducting this analysis and creating this video. Truly AMAZING and soooooooo appreciated. Keep up the GREAT work and THANK YOU!!!! You my thumbs up and subscription.

This was pretty quick, I thought it would take at least 3 months. Thank you for all that you do.

Wow insane dedication! This is so thorough thank you for this, especially the sleep accuracy as I have the watch 4 classic and im dubious of the sleep accuracy. It never records after I wake up to pee. Super annoying I wish you a million folllowers! You deserve it bro

First video i ever watched on your channel, but it was so good that i knew i would subscribe even without you having to ask me for it at some point during the video (which was also a couple seconds only, that is also to be appreciated!)

Will we see Fitbit Charge 5 tests soon, cause I am very interested if they made it accurately? Thanks for over 2 years of hard work Rob. Your experiments and accuracy tests are really appreciated in the "any kind of workout people" society. In the beginning I was really sceptical about bands, rings and watches accurately measuring heart rate and sleep stages only from wrist or finger readout, but you proved me wrong (just in some cases :D ). I bought Fitbit Charge 4 and improved my overall workout cause of you and your tests data and I thank you for that one more time.

What a great channel, thank you so much for your professionalism!

Amazing how Fitbit is still the best sleep tracker even with the newer competition! Thanks for doing the tests!

It's extraordinary that Samsung or many other manufacturers can list sleep tracking as a feature when it's very poor accuracy. No accountability.

I rely on the phone to detect sleep tracking for me it's more accurate

I find the sleep tracking pretty accurate in terms of timing. As far as the stages are concerned, no real idea.. though I can definitely correlate my grogginess from a bad sleep to my current sleep score. Some times I get 8 hours of restless sleep and get a low sleep score and I feel like crap in the morning and inversely a 6 hour sleep with a high sleep score I wake up feeling great. I realize this is not terribly scientific but I do feel it's pretty accurate. I do also have the latest update, so who knows. The heart rate is really the only other thing I would care about. The other things are just gimmicks but it's nice to know while not entirely accurate, they're accurate enough to measure a problem. Overall for my unscientific purposes I enjoy the watch's functionality. I wonder if redoing some tests with the new software would yield different results.

The location on the body of the various sensor devices vs the galaxy watch 4 should be taken into consideration. For example the watch may detected more wake time being worn on the wrist vs the Zmax EEG since your hand have more range of movement vs the head.

Bro, really great review. So so so great. Appreciate that. I was finding this time of video from past 2 days. And found now

Thank you for the in-depth review. Like others here I was really hoping to get the GW4 but now will be putting that on hold to see what else is coming out. Fitbit Charge 5 is the next on my list as it also has ECG. Will you be re-looking at the GW4 if a firmware updates comes out that claims to fix most of these short-comings? Also any chance of ECG testing?

Thank you for this amazing work, congratulations 👏👏👏

Thanks for putting in the time to make this video! ugh its tough to see samsung smartwatches fall so far behind. I like the appearance of the device, but I guess this year isnt the one for accuracy again. I bought the fitbit inspire 2 early this year and will be holding on to it until something better comes along for android.

Thanks for the video. Amazing work!!

Too much appreciation for this video mate 👍. I can see you have put lot of work to make this video. I have Fossil Gen 4 & 5 and now ordered GW4. One thing I want to say smartwatch are not health tracker only. It has other functions related to smartphone i.e. Notification, calls, different type of tethering etc. So it must have limit to do all such health related functions and smartphone function together.

Thank you for this Rob. I bought the watch despite your not having tested it. I suspected sensor galore, more than ultimate accuracy. Hopefully performance will improve with updates. In addition there are third party sleep tracking alternatives, Would be interesting to see if they do any better than the native one.

I am having the same kind of sleep readings on my Sam Watch 4 with almost no deep sleep even though my Sam Gear Fit 2 shows me as motionless for most of the night. I am actually glad to see your similar findings since I have A-Fib that I thought was the culprit. I did not know the 4 should take BP. I can run an ECG, but nothing comes up for BP on the Sam Health Monitor APP. Maybe because I still have a Sam Galaxy S8+ for phone. Thank you so much for the review!

Galaxy watches are really great for smartwatch use only like phone calls, text, alarm, spotify music player, GPS, mobile payments which probably is not available in iran for galaxy watches. Other than that, the only good thing might be step counting and heart rate, the rest of the other measurements are inaccurate.

Good work, very useful information.

Thanks for this. I am seriously considering buying the galaxy watch 4 for its health monitoring function.

I'd probably stick for now with my Amazfit T-Rex which still fits my requirement and style.

Awesome work 👍

Big fan of your reviews. Thank you for doing this regularly. You are amazing. I had a request though. Could you please do the review using Google Fit on the Galaxy Smartwatches now that Fit is available on them? I know Google Fit doesn't do Sleep tracking but would love to see if it improves on the heart rate tracking accuracy over Samsung health?

Is it possible for you to rank all your tested watches with average scores? I love how detailed you are, but after finding one watch that has one particularly good attribute, its tough to then understand if it greatly lacks in other areas compared to the others
