That rare moment you find a RUclips video review that is based on actual tests …thank you!
It feels like I found a true gem on RUclips. Your channel is such a delight. Keep up the cool and geeky work! It is much appreciated. 🙏
so true!!!
What this app is rubbish
@@sarvove he's talking about the channel not the app. and the app does what it advertises so not rlly rubbish
@@boxlad7583 if you saw my results you would say it doesn’t work either said I was awake all night
@@sarvove were you using the watch variant or the phone app? bc the watch uses an accelerometer which tracks your movements. Maybe you move an abnormal amount in your sleep?
I also have a scientific background and I’m just amazed at the quality of this video. This was done with better methods than many scientific articles! And a discussion about limitations and future avenues at the end?!? A-MA-ZING!
Just imagine being as happy as this guy is. Truly a blessing to love what you do for a living. World would be a much better place if everyone found that. Most people are miserable and hate their job from what I've gathered especially those in this field.

Of course, only buy it if it makes sense for you!👍
Thanks, I love these videos. Can('t) (wait until) you test 'AutoSleep" app for Apple watch. They Are the only ones who have a respectable privacy policy (your data is your data only), and they also have export tools.
edit: I should have waited until the end :)
Excellent analysis. I wonder if you are able to provide an update for this year as to whether the app made any improvements to its algorithm or it’s just the same. If you are also able to shed any further analysis on sleep apnea functions of these apps that would be extremely helpful and appreciated
Man you're a scientist, a researcher. Bravo!
Love the high quality of content and production! Looking forward to every video!
Thanks Freddy!
I use Sleep Watch on the apple watch... it seems to track the same things including HRV, sleep rhythm across days and some other stuff too.
Thanks for this! Finally some proper scientific approach to this topic, you earned a sub :)
It would be great to see a comparison video where you talk about the pro's and con's of sleep cycle and other similar apps!
His smile and overall friendly nature just made me click the like button without even finishing 1 min of the video
Thanks Ahmed!
Thanks for taking the time to do thorough reviews with in depth data analysis about these products. Super helpful! Now all we need is for *you* to develop an app for the Apple Watch that actually works (hint hint).
You didn’t like it?
Excellent review as usual!, autosleep and sleepwatch apps are quite popular as well, would love to see a review on them as well!...Happy New Year!
Thanks! Will do!
Pillow is an old classic app as well, I'd love one of that
Love using the sleep cycle app. I have tried using it with and without the wake up window and I much prefer using it with the 30 min wake up window. Find myself much more awake and alert when I wake up
where do you put your phone when sleeping
@@MattGarcyaDC just on my nightstand on the charger
I find the wake up feature very usefull. To me it always seems to be spot on waking me when im in light sleep.
Love your videos! Could you make a video ranking different wearables (and Apple Watch apps) according to sleep score accuracy?
That would be amazing
I have apple now but I can say for certainty that the Samsung watch 4 is the BEST sleep tracker between the two! It lets you know how much light sleep, REM sleep and deep! It’s amazing.

Love this dude - more on Fitbit please!
Thanks so much!!
Fitbit is lame. You’re welcome.
@@xblowsmokex That's not what the dude with nearly 20k subscribers says! Congrats Rob!
you have the BEST reviews on youtube for all these related topics, with actual tests and data that can be used
when you read reviews of apps on the app store, the only part that's actually reliable is people's experiences with the UI - any comments on actual sleep tracking data can't really be used, so i really appreciate your videos
so glad i found your channel - hope you keep growing!!!!
I've been using sleep cycle for over 7 years now and I would like to see a comparison between the watch and phone app. Typically on the watch app, I rarely have a score below 60, even if I had a night with a lot of interrupted sleep because my daughter woke me up whereas with the phone app, I have score below 50 after nights were I didn't sleep well and feel really tired in the morning
up
yea
Wow 7 years. You obviously rate the app highly. Do you pay for the app or use the free version?
Found your channel two days ago and am blown away by the quality of your investigative reviewing. Delighted to have you on my Subscriber feed 👍🇮🇪
Thank you so much for the review! Can't wait for the rest of the apps.
You should test the native sleep tracking on apple watch as well. Maybe another idea for a future video is testing to see if the smart alarm actually wakes you up during light sleep and not rem sleep
He already tested it
Pretty interesting results ! Would it be possible that you test the "Sleep as Android" App in the future ? Not sure if this app is compatible with the apple Watch though.
Samsung Galaxy Watch 3 has this programme integrated inself, in Samsung Health
There is no one out there doing this kind of detailed and thorough analysis of the Apple Watch. Thanks!
Just based off my anecdotal experience, sleep cycle is a total game changer for waking up.
i'm looking forward to your Sleepwatch app review!
Thank you so much for your review Rob!
I don’t know, I feel like you’re being a little generous to Apple. Considering the hardware in the watch they should easily be able to track sleep cycles comparable to Oura rings. Yet Apple’s data that they give us is extremely vague and in my opinion not that accurate based on your test here.
It’d be interesting if you did the same test but with the new Oura Ring 3 instead of an Apple Watch. Or maybe even throw in an Apple Watch 7 to compare both of them to actual scientific equipment. Since one goes on the wrist and one goes on the finger they shouldn’t interfere.
Otherwise great video man.
What isnan oura ring
Interesting but I don’t wear my watch to bed and I charge my watch only at night when I sleep
Man I followed you soon as you said you are an actual scientist
Would you be interested in comparing the Sleep as Android app on Android as well? It's well regarded to be very accurate and featureful, I'm currently using it, but having a professional opinion would be interesting.
What do you recommend as the best overall fitness tracker? Apple Watch SE, Garmin Venu, Fitbit Sense/ Versa 2or3 or another? I am interested in sleep, steps, heart rate, stress management. Thanks
Apple Watch for sure
Apple Watch
Apple watch SE User here GOGO GET IT
fitbit for sleep tracking. everything else apple watch
@@TeVeTeVe does it have to be the Apple Watch SE or can I go with cheaper ones?
Hope you do AutoSleep!
Yes please Rob! i came here to comment the same thing :)
If he will do it and it’s accurate ill buy the app. Only reason i haven’t bought it is that im not sure how accurate it is. Edit: says in the video he will :)
@@Jampper He has reviewed it. Check is recent videos.
I have used Sleep Cycle for over five years and can confirm it frequently wakes me during REM sleep...
Your data analytics skills tingle my love for stats and neuro
Hope you do Galaxy Watch 3! These are great
Thank you so much! This is a truly great RUclips Chanel and I wish you good luck in future!
These kinds of analyses are much better than typical youtuber product reviews!
You are now my go-to authoritative source for sleep tracking info! Thanks!
As someone else has stated could you please carry out a test with "sleep as android". They've been around since 2010. That would be really interesting. Keep up the awesome video's A+++
Amazing analysis. I'll test the app. Thanks
Thanks for the review!! I was wondering how accurate the app is. Been using it for a few months
Appreciate it Kevin!
Wow. You put so much effort into making these videos, you're great. Thank you.
This was exactly what i was looking for. Keep up the good work. Subscribed to your Channel!
Wonderful!! Please make more this kind of videos. We definitely need a lot more scientific tests on youtube.
Loved you!!
I love your videos, I don’t know why you don’t have a milion of followers yet 😅
Thank you so much Antonio! One step at a time 😊. When I actively started working on my channel about 9 months ago I had about 150 subscribers, and I am already so happy that so many people enjoy my videos enough to spend their valuable time watching things I create. I still quite often get that imposter syndrome feeling, where I think "why on earth would people take my advice?". That being said, I am super happy with all the positive comments and feedback I get. I would never have though I could even get to 1000 subscribers, let alone the 10.000 kind people that follow my channel now. Have a great day!
@@TheQuantifiedScientist I wish you all the best 🙏
@@TheQuantifiedScientist It's just a matter of time until RUclips's algorithm picks you up. It's all about consistent uploads and a good like to dislike ratio. I've seen channels upload weekly for a year with 100-1000 views per video, then suddenly explode into millions of views. This channel has potential not gonna lie.
You dutch btw? Your accent sounds dutch lol. But you said you live in Vienna/Austria.
You should test also sheep as Android witch is the most important Android sleep app
Could you compare some sleep cycle apps (without watches or bands) with EEG device please😄
So you have reviewed all the sleep apps for Apple Watch and iOS. Which one is the best?
Hey Rob, I am hoping you would revisit the experiment with sleep cycle app but without an apple watch connected, just purely from the phone's sensor. Been using the app for a year and would love to see if the readings are anywhere near accurate. Thanks!
Same, I don’t like to use wearable device while sleeping. Hope to see a video for sleep cycle without Apple Watch.
happy new year Rob. great video thank you.
Thanks Roberto!
I’ve watched your review of Apple Watch 6 and the Sleep Cycle App as well as your review of the Oura Ring 2. In your opinion is the Apple Watch as good as the Oura Ring for sleep? Do you feel it would be overkill to use both?
Endlich ein richtig gutes review DANKE!
Bitte!
Do you still plan to publish a test of Sleep Watch app from Bodymatter ?
Would be great to test the sleep tracking on Watch OS 9 … ! :)
Could you do the Samsung galaxy watch 3? Great work stud.
Best reviews of this kind, by far. Thank you for the work you put into these!
I appreciate that!
Do you have any test video where you test sleep apps while using your phone and not a wristband/watch?
Thank you for this. I use Sleep Cycle for a long time, and it helps me a lot. However could not make it work in my Apple Watch. Liked the way you extracted the values of the chart.
I had to restart my Apple Watch mate. Then it worked again, just a heads up :)
Do you find that the Apple Watch app is less accurate? I don’t think it picks up when I am awake as accurately as the microphone.
@@andre.shaw91 I feel the same way. The AW does not pick up that I’m awake.
How can I even active this on my Apple Watch? Or do I just have to set up the alarm on the watch instead of the phone? I am wearing my watch in bed but have the feeling that sleep is tracked via my phone 🤔
@@michierh2886 Yea you have to set the timer on your Apple Watch, not your phone
Kudos for this very impressive analysis! 👍
you doing an amazing job!!! thank you so much for your behaviour attitude for such an interesting, useful and important topics!!!
Just amazing info and data. Thanks for share your experience with this app.
Looking forward for the app comparison :)
Excelent inside, Im using sleep cycle for +2 yes now and want to know more about my sleep so this is really great content!
This is top quality analysis. THank you
its been 3 years since you did the app review...
could you do a new review based on the latest version and technology from apple watch 9 series and iphone 15 to see how this app preform today ?
Firat of all, thanks for well detailed and informative videos.
I like to ask if you also plan to make benchmark regarding smart scales, like Fitbit Aria, Whitings, Tanita etc.
Nice review! Couldn’t find the Sleep Watch App review video tho.
Very awesome video. Decent job in researching and interpreting.
Glad you enjoyed it!
It feels to me like there is a misunderstanding here: I assume that the SleepCycle team uses "light sleep" in a broader sense, including REM sleep. If the app wakes you app when in REM, it would according to them be a good outcome. According to you it would be a bad outcome because you understand their promise to wake you up in "light sleep" as meaning "light" (!= "REM"). From what I understand, the goal of the app is to prevent your alarm from going of in deep sleep because that would make you groggy in the morning - or so goes the assumption of this. I don't know what the current state of scientific consensus is regarding best wake up time in the cycle, though. If you do know, I would love to hear from you!
I have been searching for this video for weeks!!!
this guy deserves much more appreciation
This is a great video. Can you also test the Sleep Cycle Apple Watch app to see if it is as accurate? I am assuming your testing only used the Sleep Cycle app which detects motion through the microphone. The Apple Watch app will not be using the microphone.
Well researched and thorough video. Thanks for sharing this.
As someone with a scientific background, your videos do an excellent job at testing different trackers. Subscribed!
I loved it! Subscribed right away ❤️
I could notice that in the second night, the REM and Deep Sleep could be almost exact if added an offset in the timeframe of sleep cycle, maybe it's some minutes off because you had to get the graphics through that tool, not raw data in itself
Hi!!
And what is the best Apple Watch app for sleep tracking?
How tight does the Apple Watch have to be?
Cool video, thank you!!!
So which app is the best out of the ones you’ve reviewed?
This one.
I have sleep apnea. So my machine does some but I'm struggling w the right pressure. Also moisture builds up in there n makes it side off over my chin or I think that's what it is. I just got it back from a recall n really having a time.
Any chance you can do the Samsung galaxy watch 3 as that is fda approved? Great videos.
Test auto sleep please
Will do!
thank you, that was very informative
I gave a thumbs up already for your 2:28 test 😄
Did you also test the microphone mode on sleep cycle?
Hi! Not yet, but I actually started trying it out now. Running both the microphone mode and with another device on the bed itself
@@TheQuantifiedScientist curious how this comes out. I use the microphone mode. I have more than 4 years worth of data in Sleep Cycle now. Might be closer to 6 or 7, but definitely more than 4. I’d have to look later.
I have smart watch (not apple ) . Should I track my sleep with the watch or with the sleep cycle app
I’ve been using this app for years, and I find the app to be pretty accurate, but I’m curious to know which setting you used to track your sleep? The gyroscope, that monitors movement on your bed, or the mic, that monitors sound (a recent update listens for snoring too and marks them on the graph as well)? From what I know the Apple Watch only tracks heart rate (the red dotted line) and has a quiet alarm feature that gently vibrates. In your video you didn’t mention which setting you used, and you also didn’t mention anything about the heart rate info from the Apple Watch.
I always enable the alarm on my watch but it feels like my phone is tracking my sleep (motion/accelerometer) since getting up in the middle of the night and leaving the bedroom (where the phone is) is not tracked as awake. I am a bit confused how to turn on tracking via apple watch?
@@michierh2886 go to settings -> sleep on your watch or watch app and scroll down a bit. You can turn it on or off there. Them after you wake up you can see your tracked sleep in the sleep app.
Do you favour this app in comparison to the others mentioned?
Would you still consider it to be worthwhile to use the app even if I’m using it only on my smartphone?
Awesome video! It would be great if you could also analyze the sleep tracking accuracy of Garmin devices!
Small thing to share: you can export the raw data of sleep cycle in the settings :)
Actually, no. The data exported are just the date, time, quality and another information not so usefull. There is no data of all the night indicanting when you were sleeping, awake or something. To access this data, I think, you have to copy the SQL files directly from the apps folder with some software capable of doing that.
The exported data look like this, a least, on my version:
Start; Final; Sleep quality; Time in bed; Awakening; Sleep observations; Heart rate; Activity (steps)
2018-03-12 23:36:20;2018-03-13 07:16:50;90%;7:40;;;0;0
2018-03-13 23:26:37;2018-03-14 07:23:32;72%;7:56;;;0;0
Would you recommend using a Apple Watch witch Sleep cycle or the ora ring?
This us how a tech review should be.
Hey Rob! Nice video. When is the Polar smartwatch review going to be up?
Hi Eloisa! It will probably take at least a few weeks, I have some other videos scheduled first. Sorry, but I can only make one video per week, as I do this in addition to my normal research.
I am selecting apple watch app. For track sleep
I am selecting between sleep cycle/pillow/auto sleep
Any recommendations??? For the premium price is around 15-30 usd. It almost the same for me
Would love to see a comparison between the Apple Watch’s app and the Sleep Cycle app!
Subscribed and liked. Nice to find you.
Great review. In your opinion does this do as good a job for sleep cycle tracking as Charge 3/4?
could u pls test the science behind -sleep detection- found on the Samsung watch 3,
and is there any long term health issues using such wearable technologies? regarding the constant and prolonged exposure to their sensors?
