God your voice is so relaxing!!! Your speed speech is perfect, my English is not very good, but I can understand everything because I have the time to translate in my mind, and I don't need to go every time back to video and hear it again!! I believe you are the greatest smartwatch reviewer. With statistics and scientific analysis. If you can compare more data from smartwatch (for example jump rope, is accurate how many jumps you have done, or your weight lift, how many sets you have done, is accurate? For swimming and bicycle you have done etc) that will be dominate for the other reviewers!!! And GPS accuracy, because I believe lots of us we run outside. How accurate is about distance, step counter etc. That will be excellent to! Thank you very very much!

Wonderful channel! First of all, thanks for your videos. I really appreciate them. Could I ask you to suggest me a sleep tracker (about 100/150 €)? Generally they're not so accurated (at least compared with a scientific EEG device), I see. Is it worth to buy one? Thanks again.

[@choisansanartist]

Great video

[@jiff1982]

It would be interesting if you add a comparison with a oximeter device either the eeg device or other, to smart watches oximeter. As the oxygen level also would be beneficial for sleep stages and people who have sleep apnea granted it only would apply to smart watches with these oximeter with continuous or partial reading during the night

[@Limpfoo]

[@pmcmpc]

@The Quantified Scientist any idea whether a Strava app is being developed for Harmony OS? The GT3 and Watch Fit New are HarmonyOS based, as will be all Huawei wearables (and phones) going forward. I can't get a straight answer out of Strava ... but it would seem mad not to develop one for a market of hundreds of millions of devices (many old phones will 'upgrade' to HarmonyOS).

@@TheQuantifiedScientist maybe you could test watch 2 in comparison with samsung band fit 2?

[@onlineservices2050]

Great video. Sleep tracking and awake vs sleep time is very important to me, so it sounds like my Charge 3 is an excellent device for that. I believe that the additional feature that the charge 4 has that my 3 does not is the built in gps the which isn’t useful to me. Do you believe the Charge 3 is as effective for sleep tracking as the Charge 4? Thanks again

[@TheQuantifiedScientist]

Totally agree, as far as I have seen these are more or less the same! The Charge 2 is also a good sleep tracker still :-)

Is the zMac EEG is avaiable for purchases? Does it cost the eyes of the person? 😅

[@pvwg]

Do you plan on testing the SPO2 sensors on most or some these devices in the future? For me, I'd actually consider it a big (if not the biggest) part of sleep tracking for apnea events, though I understand that there won't much interesting values to see for healthy users...

[@TheQuantifiedScientist]

Hi! Yes, this is the plan, but testing this is more difficult. I have some ideas, but I would still struggle to artificially/intentionally reduce my SpO2 levels. Have a great day!

[@BlackMamba-lt8oe]

Spo2 testing is void i have checked.they are normal

[@NjoyMoney]

Hello, you should also compare the watches to the most accurate watch there is. To see how much worse it is compared to the most accurate watch, then people can decide if the extra money is worth it 🙂

[@guilhermeg345]

I recently bought this watch but I'm having the same problem as my previous smartband, it doesn't detect the awake times. I wake several times during the night and usually I keep turning around in bed until I fall asleep again, I even pressed the button to turn on the screen as suggested in huawei website to tell the watch I'm awake but still it doesn't detect. Also even when I'm still awake on the phone laying in bed it detects as I'm already sleeping. I have Trusleep on. Very upset with this.

I have tested my Huawei Watch Fit, when the Huawei True Sleep Mode is DEactivated. To me the result looks way better, but showing only difference between deep sleep, light sleep and awake. So it will not tell the REM, but beside of that, the result looks way better to me. Maybe you want to try it in comparison with your sleep equipment and let us know, what you think about...

Interesting. I had a huawei band 2 prior to my new watch fit mini and at the time it was one of only a few trackers that included REM. Since I have Narcolepsy tracking sleep-onset-REM and my body's favourite REM-deep sleep-REM is pretty important to me. I compared electrodes to the band 2 results twice and it was pretty close for me (my doc was impressed). Idk why it seemed to have better results for me even though it was true sleep 1.0. I don't have something one could call a sleep cycle anyways (too much REM switching), so that's not something I'm looking for ^^ I'll compare results with my watch fit mini when I have my next appointment. Btw, I'm pretty jealous of the eec, last time I had like 9 electrodes all over my face.

Can you recommend any watch at all? Which is the best? All your videos basically say none of them are accurate

[@truthseeker6804]

depends on what youre going to do. if you want a watch that tracks sleep stages then get fitbit. but realistically most people dont care for tracking sleep stages, i dont see the logic in that, so you would want a watch that track heart rate, or spo2, those seem more reasonable. regarding heart rate it also depends on what youre doing, if youre doing alot of extreme exercises like weight lifting then no watch is perfect, but apple watch is good. but for simple workout like running walking etc most watches do well.
