Rob, you have just confirmed what I have been suspecting is the mistakes that my Samsung Gear S2 have been making these past couple of years I have been wearing it. Thank you so much!!!
It is consistently slightly undercounting my steps whenever I compare it to manually counting a few hundred steps.
My heart rate also was many times off compared to manual counting it. yet I was not capable of testing and plotting it so precisely and brilliantly as you have.
sleep also never seemed right to me but I had no way of testing it. How I can see that it is making the same mistakes as your Samsung wearable.
You are brilliant and publishing on this CZcams channel such greatly needed work!
Thank you again, and keep up your great work! 👍👏👏👏
Thanks so much Mike!
I wait religiously for your videos, they're so good right now.
Thanks so much Garluis!!
Great video! Im a bit dissappointed that the fit2 performed so poorly. Can you do a "1 year later followup" on it? Maybe the software improved some of its capabilities. Keep up the good work!
I am really happy finding this channel. Thanks for your dedicated reviews and to see a one for galaxy active2 in the future.
Thank you for providing such high quality, quantitative reviews. I imagine it takes you a lot of time to do these :)
I'm waiting for the "OH MY GOD...this is the best fitness watch ever! It's exceptional! Everything was within 98% accuracy. Buy it NOW!" review. Sadly, that will never happen. Every watch no matter the price has its shortcomings. We are many many years away from serious contenders. To be expected as we're in the infancy stage of smart watches.
@Hani A Yeah, after watching a bunch of his reviews, fitbit looks pretty good, definitely very good sleep tracking. If he ever did a best watches list, fitbits would be all on it.
Get a garmin or Apple Watch
@@cinemapigeon4898 I feel like it's only true for sleep tracking. Heart rate is still kind of odd
1st time watcher, very high quality video.
wish you had included a caloric comparison
Your videos are so helpful. Thanks for taking the time to produce these :)
You are THE BEST. Thank you for your highly detailed, unbiased reviews
Glad I found this channel. Finally, someone does review differently. Really enjoyed it. And decided to go with Fitbit
I just decided to ditch Fitbit. Their product is defective but because it happened after 1 year their said oh well not our problem.
Hi Rob! Thank you so much for your hardwork on this video! Too bad I didnt watch this video sooner before getting one last year Dec 2022. Def will be checking out your other videos to decide on my future health tracking device purchase!
Thanks a lot Rob. Love your reviews! Have a great week ahead
Thanks Xavier! You too!
You have inspired me to dig out my Zeo Sleep Manager EEG which I was able to pick up really cheap many years ago. I want to compare the sleep accuracy of my Garmin Vivoactive 3. Love your channel! (Too bad about all the bad press on Scan Watch).
Would love to see the Samsung Galaxy active 2 next!! Its gotten pretty cheap these days like $100 in the US, has blood pressure, HR, EKG (might need to sideload an app, as im not sure if its passed EU regulations)
Waiting for this too. Might upgrade my Mi Band 5 if its metrics are better.
Hey hey ! Loved the video ! For the heart rate "dot comparison " (first HR graph), it would be cool to have the standard deviation relative to the polar ! That would give a good comparison data against others !
Great Review! I appreciate these types of vids. Can you do one for the Galaxy Watch 3?
Thanks to you I got my first fitness watch, your vids r straight to the point and save people time, sub and liked! :D
Which do you buy?
You explanation is very scientific and clear, please keep presenting videos like this, thank you, God bless you gentlemen...
Great video as always. I hope you can one day do a review of a those cheap chinese no-name sleep/ecg/temp/ox/hr/activity watches you can buy from aliexpress or banggood for 20-50 usd, would be really interesting to how they compare to the big brands.
Hey Quantified scientist, I love your reviews and love that you care so much about the health and fitness sector.
Can you please do a review on breathing training equipments like the airofit etc?
That would be amazing, they are expensive hence knowing whether they work or not will really help make a purchase decision.
Sheesh. I wish you already had tested this 3 months ago when I bought one for my gf. This device is actually pretty good as a light version of a smart watch, since it is pretty good with notifications and detects when you exercise. The Samsung app also has some pretty good training programs. But the measurements accuracy is pretty bad.
Thanks a lot, and I like your step by step approach. It's just like you are presenting a scientific article in a congress. I can learn about the devices and learn about presenting methods.
Wish you lots of success
Thanks so much Flavio!
Thanks for saving me money. I'll be going with the Fitbit Inspire 2 per your recommendation.👌🏾
Strange, Fitbit did horrible for me but fit2 has helped me improve my sleep dramatically . I guess mileage may vary lol. I plan to get the apple watch when new one is released. I could not recommend the Samsung Galaxy Fit2 enough. they are both so inexpensive, easy to buy both to try. thank you for all your hard work and data. looking forward to further reviews.
Incredible content! Thank you.
Great review. I am also not satisfied with it, mostly due to software (un)friendliness with iOS.
However, I did notices that HR heavily depends on the position on the hand. The more it is closer to the wrist it is better. Also, the sensor it uses for HR is completely different then most of other wristbands, due to which it has measurement inertia, and all other issues that come with it. Try repeat some of these tests with the band closer to the wrist.
Additionally, even if it can be easily removed from the band, it performs poorly when it is in the pocket, e.g. as a step counter.
Awaiting your review of Samsung Fit3😊
I recently found your channel bro.. and the content is just wow.. Accuracy is more important thn a feature. Ig.. it's due to the code it performs worse in sleep test.. I found similarities in tht visual like it's detected most remp sleep as wake... So, I guess the way tuned is differed like in terms of accuracy thing... Anyway it's really great work bruh
Love you honesty
Love this video! Thank u so much 😀
nice video!
so underrated !
actual review of electronic devices,. Thanks man,.
Great video. Congrats!
Keep going your great man!!!
Good job as usual !!
Thanks Rob !
Could you do more Apple Watch apps and/or Garmin Fenix? (The sleep tracking that is)
Great video! After this, I’ll refer to your Xiaomi video to compare and decide :)
Excellent review 👌
nice video...thanks...now i know what is the right band watch to buy...👌👌👌👍👍👍
Hello! Really enjoy all your videos! I purchased the Inspire 2 thanks to you!!! Just had a quick question in the fitbit dashboard settings for my device, I notice that my fitbit is toggled to have sleep sensitivity to normal, was wondering whether you had it on normal or did you select sensitive when performing the studies that you did for your of your inspire 2 video.
please make a video for newly launched fit3 aswell
and love ur videos
Useful information ,as always. Nice review sir
Glad it was helpful!
What does REM mean? This is the first video I'm watching of yours, and I am pleased!
Rapid Eye Movement, you move your eyes quite much in that phase. You also often dream in the REM-phase ^^
Please test the Galaxy Active 2, and do you have a list rating the different smartwatches/trackers you've tested?
Great channel, pure data to compare. So I have to look for other device.
Great Video! Im wondering if the more expensive smartwatches from samsung have te same sleep tracking issues. Would love to see review of the galaxy watch 3 if you are able to get your hands on it. Would also like to see if you are able to measure the relative accuracy of of spo2 and the bloodpressure functions that the galaxy watch 3 offers. Keep up the good work!
Thanks! For sure, I hope to test it soon. (If someone can convince Samsung to send me one for testing that would be even better ;-) )
Thanks for great video.
According the user manual Fit 2 has slight delay in step counting. It doesn't count steps immediately. In such way, i guess the step test results should look a bit different.
Hi V A, thanks for in info! Not sure if this had an influence. Since I did these segments mostly back to back, the numbers should in total not be affected too much, but it might have some influence indeed.
Can any of the Fitbit gadgets give you a vibration alarm during specific types of sleep to aid lucid dreaming etc?
Boa review, gosto muito dos seus vídeos!
Muito obrigado! (#googletranslate) ;-)
Galaxy watch active 2! I would love to see a video with that one
I am interested in buying emf radiation free smartwatch. Please recommend one with all the features like step counter, HR monitoring, SPo2, BP monitoring, etc.
Hello Rob. Im really looking for a solid sleep/general health tracker and been watching your videos. Which one would you personally say is the Best?. Agter seeing your review it seems to be the fitbit inspire 2 that is the winner???
could you please do a test on latest Miband 6 and huawei band 6 for their sleep, heart rate, blood o2 level and step count test? very interested in that
Conclusion:
The 30€ Fitness Tracker did not perform like an 100-200€ Fitness Tracker.
I can not recommend it.
Can you post video on honor band 5 ,as it seems to have more accurate results !
How about Samsung Galaxy Active 2? Would love to see more Samsung products.
Hey Rob, what are your thoughts on the Samsung Galaxy Fit 3 watch that was launched recently?
Sunday afternoon means Quantified Scientist time - can never arrive soon enough!
Thanks so much😊
Came to see where samsung was ni the fit 2 as the fit 3 just released! And boy, they have a long road to make me upgrade my mi band 6 hahahaha
Do you have any idea why the apple watch is significantly better at tracking heart rate than other bands - even in case of high intensity workouts? Or what prevents the cheaper alternatives from reading the correct values when bpm shoots up quickly? I'm trying to understand if it's really technically hard to do or just manufacturers cheaping out. From what I've seen in your channel, even the costlier Garmin watches have abysmal hr tracking when it comes to hiit workouts. One more question: how do you export data from these apps? Thanks for doing all of this.
Great detailed review! But I'm little confused that how can I (or you) measure sleep onset latency? Most of my graphs start with sleep onset (when I already fall asleep), like one of your recordings. So, I wonder that how can I calculate exactly to time spent in bed before sleep onset with using only Fit 2 graphs as base?
Please, tell us something about Garmin Vivosmart 4! How accurate is it? I'm referring to sleep tracking and heart rate accuracy. Thanks a lot!
Can you make Samsung galaxy fit 3?👀. Thank you, excellent review!
what do you recoomend for heart rate monitor?, which was is best for android users?
Could you make an updated video of this watch
We want a video about the amazfit GTS 2
Thank you and finally.
You're welcome James
thank you so much
Hello Rob, does Fit 2 has Low Heart Rate alerts?
Thanks for other’s informations.
As an unscientific fool I liked the video easy to understand and this test is something nobody else does
it would be very good if you created a table in excel, for example, compiling all smartwaches that you have already tested for us, so we could consult and verify this data :D
Hi rob, galaxy fit2 around 38 usd and fitbit inspire around 90 usd,, can you please advise that fitbit can justify this price difference? Thank you
Bro... Also do blood pressure monitor.... 💙
Good job. What about galaxy watch 3 sleeping tracker? Can you test it please:)?
I want to replace my Honor Magic Watch 2, but it looks like nothing else that looks as good, works any good. I was hoping this would be the one.
Can u tell which is best accurate Smart band and smart watches under 15000.INR
do a video on fit 3 now please!
Hi, can u review Amazfit GTS 2 pls pls, I am planning to busy it so pls, it has all other smart watch features, but step and sleep counts no other youtuber does as u validate. So pls can u? Thanks in advance!👍
which fitness band you would recommend in 3000 Indian rupees ???
Which tracker do you recommend for android users (& heartrate)
Hello! I am a big fan of your CZcams channel. I literally live right by a train line that is quite loud. I am still able to sleep 8 hours a night no problem. But is it possible that the quality of my sleep is being negatively affected without my realising it? Thanks for all you do.
James.
Man, would you please recommend the best most accurate sleep tracker among all you tested?
This is all I want
I'm looking for the same thing. Rob, what had been the most accurate device so far, please?
Fitbits all track sleep pretty well.
Can I have your opinion between this and mi band 5???
Can we see a video on the samsung active 2 and galaxy 3
So what I am going to do is get Samsung fitbit 2 for the step under count because it will help me push myself.
I prefer a slight under count than over count anyday.
And I'll get the POLAR H10 for the heart rate.
And that's all I want.
Please do this test with galaxy watch 3 & Active 2
Please do fit 3 review
I bought this for £33 which is $45 and the original price was 60 so i guess this is a good watch? I would get the Fitbit inspire 2 if it was on sale so thank you for the recommendation
Some how Galaxy Fit 2 is boradcasting Heart Rate to RGT. May I know what sleep app did you used to show at 6:17
❤️ from India, please do latest test of this band. Curious to know about its performance after so many firmware updates. Please Sir...
dear Sir, please review samsung galaxy active 4 , thank you in advance
Can you rewiv the fit bit lauxe also
1 year later follow up for this please!!
What's the most accurate heart monitor watch from all You have tester?
does it track distance accurately
I got it, it was 33 euros i think for that price its good alltough it didnt perform that awesome in your test
Where is the Amazfit Band 5 review?
Good Video sir, is there any update out for the FitBit Sense?
Hi Nils! Not yet, but hopefully I'll have time to make a video or instagram post about it soon😊
Please test the newest mi watch 😍
When you use the fit, I think it helps if you shave the hair on your wrist where you put the watch
Thanks for the tip. However, not sure if the average consumer will go that far for a wearable ;-)
even though I'm a samsung user I wish the fitbit was the same price as the samsung one but that isn't the case in my country. The fit bit inspire 2 is more than twice the price here...
