Sleep studies and statistics confirm our need for 7.5 to 9 hours of sleep every night to be healthier, feel better and be the MOST productive! Sleep cycle app not only helps you to get the sleep necessary but it wakes you up gently and only as you are coming out of a sleep cycle just when you are ready to awaken. You will wake up refreshed and be ready to take charge of your day instead of your day taking charge of you! It is a fabulous tool to help you understand your own sleep cycles and habits so you can improve your sleep for a healthier, happier life! ~ Marsha


Latest update  K_Forbes  2 star

Like other users have already commented, the latest update has caused the alarm to not function effectively. The volume of the alarm, even when turned up full, is hardly loud enough to be heard. Three nights in a row, I overslept the alarm because I couldn’t hear it. Also, the snooze feature requires you to pick up the phone as opposed to before when you could just tap it. I liked the previous snooze feature, though other users may disagree. Please fix these issues ASAP! Other than that, I have been using this app for years and have loved it. Helps me wake up more intuitively. I especially like the data tracking so I can see what affects my sleep quality and adjust daily habits for a better night’s sleep.


New Update 👎🏼  SwiftGrammer  1 star

The app has not performed well since the last big update. One night it completely crashed and the alarm did not go off in the morning. Last night it completely drained my phone’s battery, even when plugged into the charger. Won’t be using the app until it gets updated again.

Helps make sleep a priority  Elizabeth Bercaw  5 star

By tracking my sleep, I’m already placing more importance on quality sleep. Getting to bed earlier, and winding down sooner.


Alarm stopped being loud enough to hear after last update  SuperSonia2  1 star

After the last update the alarm volume went really low even though it was still set loud. It didn’t wake me up. Not helpful. If this alarm can’t wake me up then it’s pretty useless.

Floating narwhal

It’s great, but...  Floating narwhal  3 star

This app has a lot of functionality, except when it comes to the alarm sounds. Why does the app only allow you to pick songs from apple music? Why can’t I use music from other platforms to wake me up? To me, the appeal of the premium membership came from the extra options, but they really limited themselves in that area. What good is the 30 bucks a year if I have to have an apple music subscription, which would be another 120 a year, to wake up to the music I want to hear.


Great  bry4r  5 star

It’s honestly, hands down the best alarm app. The peaceful noises, the helpful tips. Just download it and see for yourself.

App needs to be fixed  Anonymous 220  2 star

I’ve been using this app since 2012, and it has been excellent. The new update has made it unusable. It doesn’t wake me up anymore. Please fix this as soon as possible. Thanks


great job on the battery usage!  drgonz86  5 star

With a recent update the battery usage went down to only 20% for full night of tracking with microphone (iphone 7), including listening to a 1h podcast while falling asleep. Awesome! Now I no longer need to use my old 5s for the podcast just so the 7 can be plugged in.


Excellent sleep app  Jrburns360  5 star

Collects very good data. Haven't used the standard alarm in a while. Alarm wake up alert wakes me gently. Ability to snooze, and set sleep notes is tremendous. Available charts really help me understand habits that help or hinder good sleep. Awesome app so far. Installed on my previous Note 4, iPhone 6+ and now on my iPhone 8.


Awesome app  Fozart  5 star

Somehow Sleep quality improved just by tracking it


Great Sleep App  ChrisiTunies  4 star

I’m very fond of this app. Pros: accurately tracks sleep and waking, movement and snoring during the night. Stores a full history of every sleep, I have 460 sleeps stored. Heaps of tunes & sound to help sleep and wake. Alarm is timed to wake with sleep patterns. Measures sleep quality based on location, weather, moon, exercises etc. Cons: yes it’s a bit expensive but I am happy now that I’ve paid for full app. Sometimes I think it’s tracking my partners snoring not mine. Suggestion: I’d love to see more updates and stats added.

Great sleeping app  Sofa V  4 star

The app does exactly what you want it to do and I wake up feeling good enough to get straight out of bed most mornings, really good app worth a try!


No longer functioning correctly after IOS update  Queenbubblypiss  4 star

Was working fine until the most recent IOS update. Now it no longer detects sound so shows “warning, insufficient movement detected”.

Dan Mansson

Watch out for auto renewal subscription  Dan Mansson  1 star

I downloaded the app for the one month trial but soon realised that the app didn’t do much for me, as I often found the results to be quite different to the reality. Frequently telling me I had been asleep when I knew I had been awake etc. One day I was sent a receipt for $40 as the trial month was up and I was automatically signed up for a premium subscription of a product I didn’t want. If you download this app because you want to try it out, make sure to put a reminder in your phone for when the trial is up so you can cancel the subscription if you don’t want it. I don’t think it too much to ask that the developer needs to confirm with you before they take your money.


Good alarm but don’t trust the data!  sezzymoo71  2 star

I like this app for the gentle alarm - but don’t trust the data. Many times I have been up and out of bed without having stopped the “cycle” and leaving my phone behind... only to return to the app later to discover I had completed another couple of sleep cycles! Yeh right?! 🤣🤣🤣


It just works.  7Apples  5 star

It just works. Been using it for years. It still works. Nuff said.

hey lets do multi

Bad app  hey lets do multi  1 star

This app is not good as it shows you barely anything. I have a different sleep app they shows me way more without having to pay.

Lachlan Towns

Great app but...  Lachlan Towns  5 star

All notifications are silent including emergency bypass notifications. If you have an emergency pager or anything similar you won’t be notified as sleep cycle muted them. It would be awesome to have a feature to turn this on or off Besides that no complaints and 1030 nights strong 😂


Don’t wake me up!  M4R1E  4 star

So the app is great (refer to the thousands of great reviews) but can you please. Pleeaase. Have a warning when starting the app that the phone is not plugged in properly? Because here I am at 2.20am... wide awake... after the app sounded an alarm due to low battery... Please. Mind you, it did pick the right time on the cycle to wake me up, as I now feel rested and energised... at 2.20am. Please.


I’m heavy sleeper  (toddster)  5 star

So I usually I can never get up from alarm clocks but so far this is the only alarm I can trust to wake me. It’s rather mind blowing


No external speaker support  Ozarksman417  1 star

Had used sleep cycle for a few years. Then got a Bluetooth speaker because my wife and I enjoy listening to music to fall asleep. This app does not support external speakers at all, even if I’m monitoring via my Apple Watch. I would GLADLY give this app 5 starts again if they would only support external speakers. I don’t understand why they don’t.

Kitty-Cat 😻

So helpful!  Kitty-Cat 😻  5 star

So, you hate that annoying alarm clock sound, huh? Well get this if you don’t have it your not human. It helps me so much! I know if I snored, I can see how long I sleep! It’s too good, I rate it a ten!


If you sleep you need this app! Just buy it now.  ArenaChick  5 star

There are some truly amazing mobile apps out there. However this app falls within the top 1% of any I have ever purchased. The one thing we all have in common is the need for quality sleep. And we’re so busy that most of us don’t have time to study our sleep habits in a clinical setting. This is where this app is so ingenious. One would think that it would be difficult to use or calibrate appropriately, but it is as easy as leaving your phone charged at night and placed flat on a surface near you. As an early adopter I have the premium features and they offer fantastic customization. Some nights it helps to call me down to listen to their collection of sleeping sounds, but my favorite feature is the slow rise which takes into account human nature in that few people respond well to a blaring alarm and hop out of bed ready to challenge the world. Instead this app allows you to wake at a desired time, but in a more humane manner by allowing you to train your brain to wake to a stress-free alarm. My other favorite feature is the accuracy of the sleep data. It’s incredible to be able to document how much time I spend in bed versus how much time I’m actually asleep, and then further discover how much deep sleep I achieve. Finally, the customer service is excellent. I had an issue with syncing my data when I changed my Apple ID and after a bit of back-and-forth the developer help me reset my login information and was extremely responsive and dedicated to resolving my issue. A special shout out to the representative Nora who became my lifeline. This app also integrates with other apps made by this developer as well as Apple health and the combination is extremely powerful. Given how quality sleep is the engine to our productivity every day, one cannot afford to be without this app!


Awesome app!!  maddiegirl2008  5 star

I love this app it helps me wake up for school because I am always late for school (5th grade) I honestly love this app in my opinion there is nothing bad about it. The 1 thing I am concerned about is when you set your alarm time and you want it for 6am (like me) it says 5:30-6:00 and then my alarm goes off between that like today it went off at 5:32 and I was so tierd! but other than that I love this app!!!


Phone app ok, watch app unusable...not worth $30  05869775  2 star

The phone app is okay... Seems to track well for using the microphone. It does think I wake up at the same time as my wife (I do not) since it must pick up the noise of her getting ready What really makes this a 2-star review is that the biggest selling point for me (and I stupidly sunk $30 on this sucker) was the ease-in, vibration wake up via the watch is completely unusable since it drains so much watch battery it doesn't even work because half the time my watch dies before it's time to wake up 😕 So 2 stars, probably up it to 3 if you're just looking for the phone side of things and don't care about the apple watch component


Don’t make me purchase this app again..  ekwon22  1 star

Why did you guys make me purchase this app for money a few years ago, only to have me start paying a subscription? If you guys are going to change the business model, at least keep the users who had purchased it prior to the change, still be able to use it without paying, we’re the ones essentially who advertised for you guys initially? You feel? Or refund us the initial purchase. Or at the VERY VERY least, give us “credit” so we can have a certain time free. That is super reasonable.


Sends notification to advertise their "new app"  MildCaffeLatte  1 star

How intrusive.


Great Alarm Clock  dbelldc  4 star

Absolutely love having this app to help ease me awake in the morning. I work a really early shift so any tool to make it easier to wake up is vital, and this alarm clock app is a big help. Especially love the Philips Hue support so that my lights gradually come on, which goes a long way to helping coax myself out of bed. The one thing I wish the developer would add is support for Siri Shortcuts, so I could turn on the alarm/sleep monitoring without having to physically grab the phone right before bed each night.


Great app no doubts very recommended  algam83  5 star

Great app


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 !


Woke me up at 4 am  Eoin12344  1 star

I set it up to wake me up at 6:30 to7:00 and it went off at 4 put it right beside me as well


I want my money back!!!!!!!!!!!  🤬angry🤬  1 star
