I'm no longer looking for a new fitness tracker. I ended up getting the Apple Watch. But your manner of speaking and constant smile keeps me watching these videos despite me not looking for a new one!
This is so cool!! I am shocked that polar vantage M did worse at detecting training HR than apple watch! As they are specially designed as sports watch! Please do Polar vantage V and especially V2 analysis!
what Apple does is black magic, no one get close, even Garmin with all their money and investment is nowhere as close, to be honest I have no idea how they differ the real data from fake readings on the wrist because of muscle tension, incomplete readings because of the intricate veins path on the wrist and the movement of the exercise, but they excel at it.
Interesting, thanks! Would also be interested in the HRV measurement accuracy. Polar's supposed to be good and some athletes even use it to steer their training
Polar calculates step counting differently. It is more an activity counter (even though they do list it as steps😒). They attempt to analyse all physical activity(biking, rowing, etc) and count activity that other trackers wouldn't accept as walking. Expect a lot of false positives. Love your videos!
Yes I agree. Just got the vantage m2, and the so called steps count is horrible. Step count should only mean counting your steps and distance. Same thing for calories burned, way overestimated !! Polar should change this. I stopped wearing it 24/7
@@TheQuantifiedScientist hey rob. I Made a comparison of Sp02 over night between garmin venu and Apple Watch 6. Maybe its interesting for you too. Tim ruclips.net/video/lApq71tI9LM/видео.html
I love your videos, really helping out with deciding which device is accurate for our personal reasons. Can you please do a video to test the new polar ignite 2 and maybe even with a comparison with the vantage M2 to see which one will be more accurate?
God I love your videos! time stamp not necessary as every minute is interesting and educational! still waiting for a device that can accurately monitor heart rate for strenght training.
Thank you for your very hard work. Your throughout testing ensured me that I've bought right watch for me. I bought Polar Vantage M almost half year ago. I've chosen it over other brands for accuracy of sleep tracking and that it has only sports features. I use it always with H10.
@@TheQuantifiedScientist Hey. I think you can ask them for sending a piece for review (not quite sure because it's out there for a long time already) or you can order one and test for a week and send it back ? If love to watch your comparisons on high end Garmin devices. I really look forward to your review about body battery working, heart rate accuracy and calorie tracking on fenix 6. Thanks for the review. Great job.
After seeing maybe many of your reviews I got talked out of buying polar and Samsung watches many times because sleep tracking accuracy is not good enough. So I decided to look to see how much zmax costs. $4,000. It is probably worth it, but financial decision is a no. Thanks for good work, you are among the most useful people on the internet. if I had a channel that reviews watches I would delete my account because it's all nonsense compared to what you do.
You mentioned that you had indicated in the setting that you wear the watch on your right hand - during the step counting test when you changed hands did you also change the settings? This actually might influence the result: my M600 got a lap counting feature for swimming and if I wore it on the "wrong" hand then it wouldn't count anything, changed the settings and instantly worked again. Step counting is probably more similar left hand vs right hand, but there still might be some difference in Polar's algorithms. Something to keep in mind when doing the more extensive testing. Great choice of colours on the Vantage M - I recently bought one too and black/copper looks so good! ;)
Excellent video as usual! I’m not sure if you have noticed it but the Vantage V also monitors HRV during the whole night. It is not possible to export the data but I’m sure you can find a solution for that. 😬 It would nice to see how it compares to the Oura ring (benchmark).
Hello my friend. As always great work. Would love to see some according to find data on the fit track watch from our favorite scientist. Hope you are safe and well.
Great work, I am also doing my Ph.D. I really like the way you explain the measurement in a simple way for everybody. The way you organize the introduction of the experiment settings then go deeper into each criterion and finish up your video with the discussion and further plan make it like a scientific paper. But why there is no comparison across devices like the one with Apple Watch or Fitbit? Please post a comparison video if you have time. :D
Hi, Rob, love your videos. I enjoy purchasing and using smartwatches. I have just purchased the galaxy watch 4 and am not happy with it. While I am waiting on the charge 5, I was looking into buying a polar watch. Were you able to gather longer results for the polar watch? Thanks Rob
It'll be most interesting to watch an evaluation on Huawei Watch GT 2 Pro. Which houses high grade materials and has a big team of engineers, scientists, mathematicians and designers behind its production of this model.
Perfect video! I like your video so much, and thank you for your effort I've been struggling lately whether to buy an Apple watch S8 or a Polar Vantage V2 i'm also curious to the POLAR VANTAGE V2 heart rate&sleep stage performance Will there be a chance for you to evaluate Polar Vantage V2 in the future? There is an index called ANS in its sleep function which i'm interested in, but apple watch doesn't have this. Besides, I also heard that Polar will release vantage v3 in the second half of this year (Maybe in September or October) or the first half of next year. Anyway, your videos support me a lot, thank you again!!🥰We support you !!!
Hi Rob. I really love your work. I was wondering if you could also show a Bland-Altman plot when comparing a watch to the gold standard. I find this easier to interpret compared to a simply X-Y plot. all the best. B
@@TheQuantifiedScientist Thank you that means a lot , I’m trying to find a good multi sports watch with accurate data ( heart rate , sleep tracking etc.) and your videos help a lot !!
Sleep interpretation is also a software thing... I could tell back then, without any measurements, that the good old V800 tracked better than the newer Fenix 5 (perhaps even my current 6X)... Fitbit ionic was correctly tracking even random sleep during day...
Always keen on those sleep tracking results! Would be great to see sleep tracking of garmin devices. I have worn Venu Sq and 245 at same night and results are completely different. I know you had VenuSQ. ;)
Excellent video. This watches sleep tracker looks very promising compared to others I’ve seen you review. Also... In each video I’ve seen so far I see you’re wearing what looks like an Oura Smart Ring. Are you doing an extended test with it, or is it your go-to for wearable sleep trackers?
Thank you very much for the video! What do you think about Nightly Recharge? It is a surprising fact and it greatly affects daily rest and sleep. It is included in the Polar.
in my personal use after half a year, it's quite accurate, at least for me. When I did not listen to it when it asked me to slow down I ended injured, when I listened to it and changed my trainings based on the intensity suggested, I had very productive weeks. In fact, I'm in by best physical condition of my whole life after 6 months of wearing the M2.
Hello my friend. Firstly your videos are magnificent. In all the devices you have checked what one would recommend In detecting a rem sleep disorder? Any opinion would be fabulous. :)
Thanks Rob! I'm seeing a lot of your videos and now it's clear that if I want to accurately measure my heart rate during weight lifting I need a chest sensor. However, monitoring it in real-time on my phone would be inconvenient... Do you have any suggestions on watches that can sync with polar h10? I only know the more expensive polar and garmin watches, however it is much more expensive on the Brazilian market (currency exchange and import taxation)
as far as I know this Vantage M can sync with the Polar H10 and nowadays you can get one for around $200, which is not dirt cheap but is fairly cheap for a multi sport watch with accurate measurements and good algorithms to track your health overall.
Thank you so much for you great work. Could you please do a review on the Polar Vantage V2. Im considering purching it because i purchased the polar h10 after watching your videos. But i only trust your opinion and would like to see your scientific testing on it first. Otherwise ill be purchasing the GT Runner since i use android.
Good video, thanks! I have Oura and Vantage M. They tend to disagree about my sleep quality, thus tried to compare sleep tracking quality based on your videos, but charts were different (in Oura sleep test columns do not add up to 100%). Any advice on that?
Any plans to test the "ANS Recovery" provided by the Polar watches ? I got the Ignite for that two years ago and have found more actionable than say Garmin's "Body Battery".
hallo my friend I want to buy a sports watch simply because I'm more interested in the subject of heart rate I want to know Which is more correct and reliable for running outside for cycling outside and inside and a few weights I'm interested in the Garmin forerunner 935 but also the polar vantage m more of the two you suggest me
I would be curious to see what you think of the Muse s or Muse 2 headbands that are supposed to track brain waves, heart rate, breathing, sleep and possibly more lol
Enjoying the scientific approach to your reviews. Would it be okay to extrapolate these results to similar Polar wearables, like the Ignite and/or Unite? I take they use the same sensors and algorithms specifically for sleep and heart rate. I ask for those of us who may have a tighter budget to work with. Thanks!
Hi Didier, I am not sure honestly. I would need to test them to be sure, which in some ways is a chicken and egg problem, since you would then have a dedicated review and your question would no longer be needed ;-)
Great stuff! I was just about to ask when you'd do a Polar watch vid ;) Curious about the sleep test, I have the Vantage V and I was wondering how accurate it is. Do you know if there's a big hardware difference between the V and the M if it comes to sleep tracking?

Or is it possible they have some weak sensor to detect brain waves to a degree? I’m just curious how they differentiate awake, light, deep, and REM.
I bought Vantage M and I am really disappointed. Heart rate reads are completely off. On interval training it shows kinda random number. I tried both wrists and different level of tightness, sometimes it catches good read and I can run an interval precisely in the bottom of my zone 4, and sometimes I'm running with my lungs out and it shows heart rate drop to an aerobic level. Runners out there, better buy a cheap watch and a chest heart rate sensor.
I've recently bought a Vantage M2 and find that the sleep tracking doesn't work properly. It seems to not record when I fall asleep or if it does its around 4hrs wrong. Last night I went to bed at 10:30pm and it said I went to sleep at 0400... has anyone else experienced this?
UPDATE: for anyone with similar issues I think I've worked out the problem. Polar allows you to manually let it know when you wake up by clicking into the sleep watch face. I've found if you click into this Polar seems to get upset and misreads your sleep pattern. Instead, I've found that syncing your phone to the Polar Flow app in the morning provides an accurate sleep tracking.
Hi friend.. I underwent heart by pass 5 years before now I am 35 year old I want to buy smart watch for monitor my heart rate.. which is your best suggestion for me..

Polar Vantage M: geni.us/0HhltOo
Of course, only buy it if it makes sense for you!👍
It would be nice to make a summarize video with benchmark evaluation about the accuracy among the various watches!
Hi Ioannis! Great suggestion :-D . I might do something like that! Have a great day 😊
Yes, I am also waiting for that! Lots of watched already tested. Time to put all together on the final battle with pro ands cons of each one.
Also, I would love to know which Fitness Watch has the most accurate resting heart rate measurement as well as training HRM
Yes we absolutely need a comparison 💪 (however, great job as always)
Please do not leave Samsung Galaxy Watch 3 out in that comparison !
I'm no longer looking for a new fitness tracker. I ended up getting the Apple Watch. But your manner of speaking and constant smile keeps me watching these videos despite me not looking for a new one!
Thats so nice Paul! Thanks a lot 😊
I've been waiting for this one since you posted on IG! Looks like Polar has a great grasp on sleep!

Literally an academic paper in video format. Love to see it!
Would like to know the top 3 watches overall that's most accurate
Looking forward to your OpenBCI videos! Thank you for all your hard work and insights you share with the community.
Polar calculates step counting differently. It is more an activity counter (even though they do list it as steps😒). They attempt to analyse all physical activity(biking, rowing, etc) and count activity that other trackers wouldn't accept as walking. Expect a lot of false positives. Love your videos!

Zit te kijken en vraag me meteen af: “hoe goed is sleeptracking op de Garmin Fenix”. Ik heb de 5, en volgens mij klopt er weinig van.
Great video Rob! Would it be safe to assume that other Polar watches, like the Polar Ignite are equally accurate in measuring sleep and heart rate?
Yeah I was wondering about the M430
Not a safe assumption, at least with Garmin, even watches with the same sensor but different tier model have different results.
Doesn't he have an ant+? If you're wearing both, didn't he pick up the signal from the strip.
