Request: Can you test the smart alarm and see if it actually does wake up at the perfect time within the sleep cycle? (No pressure, do only if you think your audience would be interested in it)
I picked up a Luxe for my wife, and a Charge5 for myself based on your reviews. They have both been fantastic! Thank you for all the hard work you put into these studies!
@@sadikatirtawan7948 it's hard to say because she doesn't wear it every day. Mine seems pretty spot on but I'm not counting all of my steps. It does however fail to measure some nights for my sleep.
Your awesome. I love the very scientific results, from a fellow engineer. Would be great if you can also test the accuracy of the Fitbit's Sp02 sensor, since it uses reflective technology, if its accurate. Thanks for all the info, really great. Keep up the great work!
Your videos are incredibly helpful. It is so difficult to find information that supports the "marketing" claims of those products. It's extremely nice to not only have access to data on all these products, but also that this information is objective and reliable. A big thank you for all your efforts to facilitate access to this information allowing us to make informed decisions and not lose hundreds of dollars on ineffective products.
I always watch these, even though I'm not interested in sleep tracking, because he's the most accurate reviewer. I'm more concerned with accurate HR, so I have gone for Polar H10 and Verity Sense
Would love more fitbit charge 5 videos! Especially analyzing the ECG, EDA and SP02 features now that it’s available. Also would love if you tested left hand vs right hand to see what’s more accurate (steps, sleep, etc)
I'm also waiting for his review of those specific items, especially the ECG and the SPO2 feats. Also HRV and skin temp. Don't care much for the EDA function though. I think ECG became recently available in EU. So probably Rob is already on it👌👊
So much work in such a detailed and well constructed way and logical way. Very impressive! Thank you for this, I feel more confident with my purchase of fitbit charge 5.
Thanks for using my data. In a few weeks i'll update it with additional ~2.5 months of data for charge 5, dreem 2, withings and oura 2.0 Long sleep onset time at 2021-06-29 (10:59) was because of getting COVID-19 and i had a hard time with high body temperature and body overheating and sweating for a few hours. that was a nightmare night :)
Just came across this video while looking for sleep tracker smartwatch reviews. Absolutely amazing! Perfect quality, data collection and video dynamics. Very much appreciated. I shall probably order the Fitbit Charge 5 (considering that it sits top right of the plot )))
Would love to see the "compared to other devices" graph... include the Apple Watch. A Fitbit Charge 5 vs the latest Apple Watch would be a great comparison.
I'm so sorry there will be no comparison chart This guy is trying to help us but its confused us more. He's not give us a conclusion which one is what, people are crying on a chart of whose the best. He give us ton of useless review, and you have to watch every his video to know what watch are the best in heart rate monitoring which is not easy, but after viewing lots of it, I forgot and confused.
1. Fitbit best for sleep tracking but heart rate is hit and miss, good for cardio, bad for weight lifting, HIIT 2. Apple Watch fantastic heart rate tracking, non existent sleep tracking. 3. Oura 3 great sleep, not much else 4. Whoop about as good as Fitbit and good community features but super expensive 5. Garmin and other brands just don’t stack up to the above
Thank your very much for this detailed analysis! I'm looking forward to your other Charge 5 videos. I like my Charge 5 so far. The only complaint I have is that the heart rate tracking is absolutely terrible. Resting heart rate is OK, but the moment your heart rate gets a bit more dynamic the reading is very much behind and off.
Nice video. I cant sleep through a night since 1,5 years. Always waking up after few hours. Drives me nuts. Already spent 2 nights in a sleep lab. Didnt find anything. Now they prescribed me a sleeping app that works best when connected to a sleeping tracker. So i ordered this one.
I wanted to buy the charge 5 so bad but read all the bad reviews on build quality and people needing to replace them even a couple times a year. Fook that. I bought Amazon Halo View. Hopefully it's decent ✌️
The Charge 5 is nice, but I would like to know whether it is accurate enough in terms of Heart Rate and SpO2...so I will wait for your full Review. The Fitbit Sense wasn't very accurate...and I won't replace my excellent Vivoactive 4s with something less accurate.
Wow thanks so much for this review! I've been undecided on this fitbit. Have been waiting to hear if new oura ring will be doing away with paid subscription but just gonna buy the fitbit now!
The conclusion I draw from watching every video on your channel is that currently we need to wear 2 devices - one that can measure sleep cycles accurately and one that can measure daytime activities accurately (and which might also need to measure overnight blood oxygen levels accurately, if the other device isn't capable!).
Found your channel when I was curious about how good the samsung watches tracks your sleep... And thank you for the good videos and you just made me wanting to buy this watch instead of a Samsung :)
Thank you very much, I've been looking for a smart band with a good sleep tracking accuracy, I've watched several of your videos, thanks for your work.
It pretty sucks that the watch doesnt tell you WHEN u fell asleep. I have the watch and ive connected it to an app called „somnio“. Its an app that my sleep doctor prescribed, and you can sync your fitbit sleep data with the somnio app. One thing thats not transfering to the somnio app is the „when you fell asleep“. Because obviously the fitbit cant recognise it?!?!
i have a feeling that fitbit’s algorithm does more of an educated guess than true sleep “tracking”. I’m thinking the designers of the algorithm know that we get more deep sleep and less REM in the beginning of the night and less deep sleep and more REM in the middle and end of the night. I think they use that to make the fitbit more likely to predict those sleep stages depending on which stage of the night it is rather than actually tracking the physiological that’s coming through the fitbit.
The Fitbit does not reliably record daytime sleep. I recorded my sleep every single night before I started working the overnight--in hopes to use the Fitbit when I started working the over-nights to improve my sleep during the day. It worked great and took a minute to Sync. Now, when I try to sync in after waking in the afternoon, the sync locks up for 10 minutes, then shows nothing :( It must have "smart"(super-stupid) AI that does not easily recognize daytime sleep. Great content. Thanks for such a great effort.
Update- the customer support is very very inconsistent. Don't give up with Fitbit customer support! The first support person-horrible. But I did get a second person on the chat that helped me reset the Lux and it seems to work now.
Thanks for the test results. Since the fitbit detects to much deep sleep, my question is: Is the deep sleep 100% defined, what it is or is it possible, that it measures the same, but for the algorithm it is not deep enough?
Fitbit is a Google company. 0% chance the sleep tracking isn't a combination of neural nets. Can't really say what exactly counts as deep sleep. Best to read up. Whatever articles say is probably what the algorithm picks up on. I'm guessing it's trained using a ton of eeg devices using Google employees which is probably why no other trackers really come close to fitbits.
This is exactly what I wanted to know - I've only had my Mi Band 6 for a few days but am considering giving it to my dad and getting a Charge 4 for myself. I especially want the better sleep tracking, and I miss the altimeter that my old Charge HR had (that the Charge 4 has but Charge 5 doesn't). If there's no sleep tracking difference between 4 and 5, I'll just get the 4 at half the price of the 5 👍
@the quantified scientist, the latest update on the Nest Hub 2nd gen now shows stages of sleep (REM, light, deep, awake), will you do an update video to see how accurate it is? Thanks and keep up the great videos!
Thanks for your videos and analysis. They are extremely useful. Also, Do you have any results on the accuracy of the devices with respect to the total calories that it claims we spend?
Really surprised that the Oura ring is outperformed by the Fitbit Charge 5. Especially cause Oura is way more expensive and backed by sleep scientist Matthew Walker
Just returned mine charge 5 after almost 2 weeks. Bought two of them, one for my mom. For her its working perfectly but for me its not tracking bev whatever I tried even when we switch them. For me it was even worse and as well for her I lost skin temperature and her lost another 2 metrics (tested after switch for 2 or 3 days). So return mine and went back to inspire 2 and order charge 4 from marketplace (30€ for charge 4 second hand but charge 5 160€ ) and yeah ecg is not working in slovakia whatever you tried (switched location,language, turned of location and also tried some things with mobile setings tried different things on both of them but nothing works )
Can someone explain why is it considered a good sleep tracker if the overall accuracy is barely above 70%? I'd expect in order for a tracker to be considered as 'good', it would need to have 95% accuracy, or at least 90% - am I missing something?
It's "good" simply compared to everything else available on the market. I bought in the last month Apple watch, garmin forerunner and fitbit inspire to figure out what is actually a good health tracker. Apple watch is a total garbage it doesnt do anything good besides heart rate, not measuring sleep stages at all and 3rd party apps are random made up numbers. Garmin has a sleep tracker but after wearing it at the same time with Fitbit I now know that it's just terrible, would say 25% accuracy. It's only good for running and doesnt make sense to wear the rest of the day at all. Fitbit's 70% hence is a real breakthrough in this case.
Wow I really appreciate your videos , they're really saving time. Can you please test the smart sleep alarm in fitbit which is wake you when you are in the light sleep or something like that
Interessant. Zou je een dergelijke test ook kunnen doen met de MiBand? De slaapanalyse daarvan is grafisch vergelijkbaar met die van Fitbit, maar gezien de prijsklasse zou je kunnen verwachten dat de resultaten minder accuraat zijn. Ik heb momenteel een MiBand 6 en overweeg een Fitbit te kopen maar ben benieuwd of de hogere prijs het waard is.
This was exciting, then I found out about Fitbit's subscription service (like the Oura ring). Sick and tired of subscription fees, will never buy this as a result.
Happy to have found this channel. I always though the Oura Ring was leading by a vast margin the sleep accuracy. If I understand well the results here the Fitbit charge 5 is crushing the competition in term of sleep pattern accuracy?
can you please test polar vantage m2 and ignite 2 , they have same heart rate sensor , only m2 has more functions.So I think it could be enough to test only one of them.
The wife and I both have the charge 5 and love it. Only thing I wish is that it would shoe me my oxygen levels throughout the night. I have mild apnea and been working on improving it. I don’t like the graph thy show that’s just oxygen variation. I want to see my actual numbers.
The Huawei Watch GT 3 came out 1.5 months ago, and it has double the sensors compared to the Huawei Watch 3 and GT 2 pro. Would you give a chance to review it? Thank you for your effort. I really appreciate what you do for the youtube community.
From all the watches and bands that you have tested, which one (beside apple watch) is the better one for heart rate accuracy during cycling and weightlifting?
I bought one of these for my boyfriend and I but your affiliate code wouldn’t work for some reason. Every time I went to check out, it said there was an error. Only worked when I created an order without the code. Sorry about that. Thank you for your videos!
This is the WORST of my Fitbits (own all Charge and Versa series). This one is trash, others per Fitbit Forum have had the same problems. Screen freeze and connectivity issues. Even after firmware updates.
I have just received my Fitbit Charge 5 yesterday aaand .. now I have realized how unfit I am, I am literally starting to feel worse. Not sure if it's in my head or I am actually dying.
Hi. Thanks a lot for your videos. They are fantastic and allowed me to learn many interesting infirmations about dreams and about devices that can help improve sleep. Could you please point to places where I can find information on how to set up my Fitbit Charge 4 to wake me up at the best time, I believe in REM phase.
Would be interested in the HR Variability. Are there any wrist applications that actually get this right? ECG stuff is just useless they should concentrate on HRV man.
Thank you! This helped me in my study, I am working to create reflection on daily occurrences throughout dream content. I was curious to know in which measurement units the EEG devices express themselves. Not sure that’s the right way to put it, but it’s a shot in the dark. What measurement units are coming from these EEG devices?
I can only afford fitbit inspire 2(although i wish i can get charge4) but glad it is one of the accurate fitness tracker out there. I just order my 1st fitness tracker yesterday. Will receive it in a few days. Simple or i might have look at it as much as time i spend on smartphone. Thanks for the percentage comparison other smartwatch chart. Hope u can allow me to show it to other person & i'll credit to u. i just hope that they have badminton sport but i guess i can use tennis(pardon my poor english)
So you pay yourself silly for a glitchy Fitbit, and then to access your data you need an additional premium subscription. And to control music you need more premium subscriptions. This company is insane!
The UNQUALIFIED SCIENTIST I bought fitbit charge 5 from london in the month of April 2022 and it gave me shoks ,then i went to India ,Here I again bought fitbit charge 5 and it again gave me shock so a big NOO to fitbit , don't recommend anything by which people die .
What's going on with the sleep accuracy chart (4:27 in this video)? Watches change position depending on video. For example Garmin Venu 2 is 65% / 43% in this video, but in GTR3 video (14 nov, 7:24in) it's 58% / 24%, same as in redmi wach2lite video (26 dec, 5:53 in), and in Whoop Strap4 video (21 nov, 6:43 in) it's 58% / 57%. Other watches moved too, like the huawei watch3.
Nice. Subscribed. Would be interested in knowing how much intra model variation these have (ie 'noise') by wearing two of same device on same body (might need to swap wrists to account for dominant hand effects.
Request: Can you test the smart alarm and see if it actually does wake up at the perfect time within the sleep cycle? (No pressure, do only if you think your audience would be interested in it)
I would be!
Yes. Please do this!
Yes! 🙏
Would definitely be interested to see this!
This still needs to happen!
I picked up a Luxe for my wife, and a Charge5 for myself based on your reviews. They have both been fantastic! Thank you for all the hard work you put into these studies!

Very helpful! Thanks!
Love your work. I like to find out about accuracy for recovery (or body battery) and maybe even altimeters (flights of stairs).
nice video as always rob, the timestamps in the bottom are a bit off though
Fitbit Charge 5 vs sense which one is more accurate.. it seems fitbit has recalled some sense watches for inaccurate ecg
This was exciting, then I found out about Fitbit's subscription service (like the Oura ring). Sick and tired of subscription fees, will never buy this as a result.
I'm still holding out with my charge 3, I'll upgrade once it wears out
Great vid thanks. I think I’ll get the inspire 2, I like the 10 day battery and from your graph/other vid, it seems to perform similarly for sleep.
I just order mine yesterday
Inspire 2 doesn't have smart alarm
@@danilascercovas6226 Have you used smart alarm? Is it useful?
Nope. I was just wondering to buy.
Happy to have found this channel. I always though the Oura Ring was leading by a vast margin the sleep accuracy. If I understand well the results here the Fitbit charge 5 is crushing the competition in term of sleep pattern accuracy?
Thank you very much for the video. What about a test of the Biostrap EVO?
can you please test polar vantage m2 and ignite 2 , they have same heart rate sensor , only m2 has more functions.So I think it could be enough to test only one of them.

GOOD JOB. SEEMS TO BE THE AVOIDED QUESTION... BUT WHAT SENSITIVITY FROM THE ONES AVAILABLE ARE YOU USING FOR THE SLEEP TRACKING ON THE FITBIT??
I am also curious...they make it kind of confusing what the real difference is.
I'd love if when you had a chance to review the Amazon halo!
I suppose just getting a scientific sleep EEG device like the one you're using is not an option unless you're either a doctor or maybe very rich...?
Spo2 accuracy is something I am very interested in as need it to see any improvements in sleep apnea

Think I have to go with a Charge 5 on my left arm and a Huawei etc. on my right, lol
wow, awesome thanks
Question, does have this kind of sleep tracking a learning curve for some days for adjusting the results more accurate?
bye the way good job Rob 👏
Great video, very informative, can you please share the link of the head band your are using for sleep tracking, thank you

Will receive it in a few days. Simple or i might have look at it as much as time i spend on smartphone. Thanks for the percentage comparison other smartwatch chart. Hope u can allow me to show it to other person & i'll credit to u. i just hope that they have badminton sport but i guess i can use tennis(pardon my poor english)
So you pay yourself silly for a glitchy Fitbit, and then to access your data you need an additional premium subscription. And to control music you need more premium subscriptions. This company is insane!
Dcrainmaker has reviewed this as defective with HR and GPS
What sensitivity setting for sleep tracking do you and Max use on the Charge 5? Default or sensitive?
I am also curious...they make it kind of confusing what the real difference is.
The UNQUALIFIED SCIENTIST I bought fitbit charge 5 from london in the month of April 2022 and it gave me shoks ,then i went to India ,Here I again bought fitbit charge 5 and it again gave me shock so a big NOO to fitbit , don't recommend anything by which people die .
What's going on with the sleep accuracy chart (4:27 in this video)? Watches change position depending on video. For example Garmin Venu 2 is 65% / 43% in this video, but in GTR3 video (14 nov, 7:24in) it's 58% / 24%, same as in redmi wach2lite video (26 dec, 5:53 in), and in Whoop Strap4 video (21 nov, 6:43 in) it's 58% / 57%. Other watches moved too, like the huawei watch3.
Now if only they can fix the weak HR tracking and bring it in line with the other fitbits
The Charge 4 would cause weird pinched nerve numbness for me. Do you think the Charge 5 will most likely have the same issue?
I wonder where does the Fitbit versa stacks up against the other Fitbit lines
Nice. Subscribed. Would be interested in knowing how much intra model variation these have (ie 'noise') by wearing two of same device on same body (might need to swap wrists to account for dominant hand effects.
