Please add sleep tracking to watch  drmurph  1 star

I like the analysis better than other apps available but they use the Apple Watch to track sleep. Please add tracking with the watch so I can come back to this app.


Latest update has issues on the Apple Watch  stixharv  5 star

Let me first say I’ve been using sleep cycle since 2014. Overall it’s the best sleep monitoring app I’ve found. But, with this latest update some issues crept in to the Apple Watch side of the app. The app still works but you can’t start or end a sleep session from the watch app. You have to use the phone side app to start and stop. I’m placing this here because I could not find a email link under the help feature in the app or on the website.

Crashes  M.E. Hudson  1 star

I’ve had this one for a while now and enjoyed it up until a year ago. The first problem was choosing a song to wake me. I had chosen one song and never went back in to change it because it helped me wake up. The app all of sudden started to choose random songs on random days instead. And no, the selection was never set on random song. It just decided to do that ok its own. Finally, I’ve had random days where I try to wake up for a workout only to miss it. I always see a notification that my alarm went off. However this morning I did the research and don’t see any analysis. Which means I set it and the app crashed in the middle of the night, never went off, never analyzed sleep, and yet still gave me a notification in my Notification Center that it went off. I see a developer response to fully charge my phone before bed and use the app unplugged. I’ll be honest, I won’t be trying that because I don’t want my phone to die before morning and the app fail because of that too. And even if it did make it, now I have a barely charged phone in the morning. Just not worth the hassle. I bought this app from the beginning. Back when it was a simple 0.99 app that worked. All the changes and subscription stuff is when everything started to malfunction.

very very bad service

WHY I WOULD LIKE TO CANCEL MY SUBSCRIPTION  very very bad service  1 star

Why I WOULD LIKE TO cancel my subscription. I am waked up almost every morning around 5:AM. I set my wake up time for around 8:30AM How can I change my choices? How can I contact a customer service person for help with my problems using your program?


Appreciate info about sleep patterns  hdpearl  5 star

New understanding about my sleep activity Motivates me to get more and better sleep


Absolutely unreliable  Jan474~  2 star

I set the mooring time to wake me up, go to bed and when I'm about to get asleep it goes off! I've used it for long time but now it's a mess.. Of course it uses half of your battery.


Can't live without  Soccerstar988  5 star

I've been using this app for around 6 years (possibly more, but I can't remember), and it is incredible. 98% of the time, I feel good when I wake up, even on short nights of sleep. The app's interface is beautiful and peaceful as well. Highly recommend.


Love it  Rowick  5 star

Im used to always having some crazy loud alarm to wake me up in the morning or I moved my alarm clock far away that I would have to get out of bed and still would crawl back in bed and go back to sleep since using this app it wakes me up more easily without a crazy loud noise.


Great just one issue  Noerru  3 star

I really like the idea behind this app. However, there is one problem, it always records my husband’s snoring. I’m not sure if there is a way to make the microphone less sensitive to it. Since it’s recording his snoring as mine, it’s not going to be accurate as to my quality of sleep.


Great App, recommended  ScarfacedTitan  5 star

Great app, I’m a happy subscriber. Request: Display the hours of sleep when the tracking begins. I want to know the hours I’ve slept before I stop the tracking.

I think this app tried to hack me  Chicken 13313  2 star

I don’t know for sure though


not enough access to app features  )((()()()()((()()  4 star

without the premium edition of the app, users have little access to many of the features of it. these features in full include many different ringtones or alarm sounds, full analysis of sleep, trends and data, and more. apart from the premium edition of the app, it is generally useful and educates users on their sleep quality and patterns.


Horrible unsolicited alarms goes off at 3am!!!  gigi_sansei  1 star

I used the app for the first time and set it up for 7:30am but it went off extremely loudly on top volume at 3am! My partner, baby and neighbours woke up and couldn’t get back to sleep as the noise was that bad ! Apparently the app was notifying me that it had low battery. I had 20% when I set the alarm up and this always last me the entire night and morning. I always leave it in airplane mode and I don’t have any apps opened. This app is extremely battery draining and should be notifying all users if their battery isn’t sufficient when they try to set the alarm rather then when they are in deep sleep! I’m a software professional and think this feature is rubbish!


Premium  swimmerq2345  5 star

Sleep cycle is a great app but it doesn’t need to have premium on and not to mention how many times it bugs you about premium otherwise it is a delightful app that I wish I had off discovered early. You absolutely 💯💯💯 percent should purchase this app no matter what


Obsessed  Photozwow  5 star

I use it every single night and have been sleeping better since tracking my sleep cycle. I think it works for me and my competitive side as I always try and do better than the night before! It’s great.


Love the Charts  Pete'sPal  4 star

This is a helpful app. The charts give a clear indication of how much deep sleep and REM sleep I get each night. In the negative,it is a clumsy process to turn off the alarm and reset the alarm for the next day.


Works sporadically  RubiRed101  3 star

I’ve used this app for about two weeks. It’s quite inaccurate and often can’t tell if I’ve silently woken up or if I’ve just rolled over deep in sleep. It has also missed a few alarms and I’ve been late to about four meetings. Do not recommend.


Sleep cycle  licygdgd  5 star

Me and my sister use it to track our sleeping and we can clearly do that


Great app  itsTBM  2 star

This is such a great app and I was really loving it.. it had made getting up earlier a breeze, I was considering buying my first app of considerable value. Last night I set the alarm for 5am and it didn’t go off in the morning😱 there was also no record of my sleep but I remember doing everything that I usually do. What’s worse I finally got to bed early so I was looking forward to seeing my first week night of 8.5 hours. I still really like the app but this turns me off spending any money on it.


App doesn’t work  Mdtp  1 star

This app doesn’t work! It doesn’t actually track your sleeping. All it does is record snoring if you do that. I have tried it for almost a month now and it hasn’t once accurately recorded my waking during the night. TOTAL WASTE OF TIME!!!! I actually rate it zero stars but the App Store won’t let me.


Good at first  MysteriousKittenPotatoe  4 star

It’s good but randomly after i had used it for a long time it started waking me up at like 4 in the morning so I deleted it and re downloaded it and it’s all good now! Very efficient and wonderful


This app woke me up at 3 am several times!!  Nadiaohh  1 star

I used to love it! I even gave it 2 more chances. But it continued to wake me up in the middle of the night with the sound that I’ve never set up! Hate it now!


What is this amazing tool?!  akivamandel  4 star

It actually works. Takes a few days to finally build a routine, but I literally wake up feeling good!!

Great-except during a tornado!  sharonakay  4 star

I loved this app UNTIL a tornado came within 5 miles of my house and the app blocked the weather notification!!! I had no idea I was in immediate danger! I depend on my phone to notify me because we are too far away from town to hear the sirens. Apparently, weather notifications are only available with the Premium version. It would have been nice to know that emergency notifications are blocked!


Great app  cathysair  4 star

Like this app Love the alarm clock Wish you didn’t have to pay for the extras. That’s the only reason I didn’t give the app 5 stars. They don’t even offer you a free 30 day trial.


Been using for 4 years, started to turn off suddenly  a7mad_civil  1 star

For some reason it started to turn off by itself!! FIX THIS I COULD HAVE MISSED WORK


Siri integration  Doctor.What  4 star

This app would be so much more convenient if enabling the alarm / sleep aid could be triggered by my “good night” shortcut that already turns off my house lights, turns on my home security alarm and runs a rain audio track. Having to fumble around with the app ruins the flow.

Very Useful  Big, Big John  5 star

Works great. I’ve got over 3 years of data at this point, and it’s great. My only issue is that with iOS it seems to prevent iCloud backups from running automatically overnight. I have to remember to run them manually every few days.


Please fix  ksubevo  2 star

I have used this app for years and never had an issue. However, After the last update the app will auto snooze and the alarm never goes off. Can’t rely on this app anymore. Really hope you fix this...

Crimson mika

Can’t purchase it in full  Crimson mika  3 star

I love this app, however I just don’t do subscription anymore. I have way too many apps I realise I am not using after about a year or so and end up paying for a year for nothing. I would buy this as a full version, even with limited updates.


Doesn’t wake me up  loklojllojllojlojloj  1 star

For the first night it worked really well but since then it hasnt been working at all and I amnt being woken up


Good  Ddddaaaaavvvvvveeeee  3 star

Would like to see how many hours til alarm when setting it and be able to turn off the alarm directly from the lock screen. Otherwise it’s great.


great app  natmags3  5 star

excellent way to get your sleep cycle under control. I aim for 100% sleep quality every night !


Fantabolous  bajebss  5 star

It wakes me up at just the right time when I’m sleeping lightly. I’m not a morning person and the app makes waking up more bareable


Too expensive €€€  Timberbaby  4 star

Interesting stats and facts. Pity you have to pay such a high price to get the full app. It’s way too expensive for what the premium package offers, which is why I haven’t paid it. For just monitoring your sleep and waking you up gently, yeah it’s grand. 4 stars, as 5 stars is just too much money.


Good  eadireland  4 star

It’s a really good app butttt the only thing is that it’s really annoying how it uses all you’re battery. I can’t have a charger by my bed so if I have my phone on like say 90% I’ll wake up and it’ll be on 26% 😕


App doesn’t work when using audio apps  Goeddiegogogo  2 star

Apps such as podcasts do not interact well with this app and prevent it from working. This is very frustrating if you listen to podcasts when falling asleep.


Review  Ellen.G.M  5 star

I have been using your amazing app for over a year now and I absolutely love it. I love the alarm clock feature which help me to get up on time. I have currently been using the free version for the last year and might consider to get premium this year. Ellen.G.M


Really good app!  Nikky🎄  5 star

This is is a really good app because it helped me sleep ALOT better and wake me up in time the one down side of it is I listen to rain on this app called " Rain Rain" and it does not allow me to listen to it while use the app thank you !
