* Sleep Cycle monitors your movement during sleep using the extremely sensitive accelerometer in your phone.
* Sleep Cycle then finds the optimal time to wake you up during a 30 minute window that ends at your set alarm time.
* Look at the screenshots for recommended phone placement.

As you sleep you go through different phases, ranging from deep sleep to light sleep. The phase you are in when your alarm goes off is critical for how tired you will feel when you wake up.
Since you move differently in bed during the different phases, Sleep Cycle can use the accelerometer in your phone to monitor your movement and determine which sleep phase you are in.
Sleep Cycle wakes you when you are in your lightest sleep phase.
Sleep Cycle was developed using proven sleep science and years of research and development.

I've been using the app for over a year. I pay for an annual of premium and haven't regretted it. The latest upgrade has some defects 1) The only alarm mode that works is the wake window. If you choose fixed alarm it reverts back to alarm window mode. 2) Analysis only sleep doesn't work. It reverts back to a static alarm for midnight 3) You can't adjust the wake window period. Setting anything besides 30 mins reverts back to 30 mins. I hope these get fixed soon. I rely on the static alarm.
Today's my 1st day of trial period n I was really impressed with the data it collected from my last night sleep. UI is not very easy, but with little tries anyone can find out the details. It even show the comparison of my sleep with others (it's fixed countries, allowing us to change would be helpful). Finally I could hear my snoring & I'm not sure if it captured all of it, but I was really impressed. It would be helpful if you can show remedies on how to avoid the snoring based on the data.
I want to like it but it's highly inconsistent and or just wrong. It's constantly saying I'm asleep after only 10 minutes when I know for certain that there are nights it takes me over 45 minutes to get to sleep. Last night for certain I was awake for well over an hour before I fell asleep and again it said 10 min, it always says 10 min. I actually wonder if any of the readings are correct or if they're random numbers except for when I say I went to sleep and when I got up. Confused!
I tried the free version of the app and I want to like but when the only sleep aid you have to play is one really bad song. . . . I deleted the app. I decided to try it again. The selection of music in the free section is pretty sub bar. Other apps do the same thing and offer better music and sound options for free. 4/28/22 edit. I decided to try again. So the sound options for the free section is worse. 1 song or the annoying voice of some guy. Quickly deleted.
It does what they say it will but there is a bug they haven't fixed. And there workaround doesn't help either. When using an exact wakeup time a very irritating bell song goes when the music starts. The recommended turning Do Not Disturb on. This does nothing. I've paid for the year and can't get a refund. Hopefully they'll get off their rears and fix that soon.
A few years ago I loved it. I don't know if they changed the algorithm but now it does the opposite of what it should. Generally seems to always choose the worst moment to wake me up. Some mornings I woke up within the alarm range, it didn't ring, I fell back asleep and rang while I was dreaming, so I always wake up groggy! I used the phone for a few hours last night and it still counted that time as deep sleep when I was clearly awake lol. They won't refund. Stuck with this bad app for 1Y
To upgrage for more features you need to buy a subscription, which I get and is fair. However it says "Try it Free", implying a free trial period, but when I clicked on the button, the billing period starts the same day. This seems like its either a bug or false advertising. I'm happy and willing to pay but I need to get a sense of how it works first.
I've been using it nearly every time I needed an alarm, but idk what happened, the last two times it completely drained the battery from around 30% give or take and forced the phone to shut down, stopping any alarm I had set. After oversleeping the second time I won't use it anymore. 2 stars because you can maybe use it when charging it over night.
I've been trying to cancel my subscription to this app for months. I haven't used it since Oct 2021, but yet I'm still paying for it. The app says I have to cancel through Google play, but it isn't listed on my subscriptions to be able to cancel it. When I try to login to the website, Google blocks them using my Google login. I've emailed several times and they just keep telling me to cancel it through Google. Whatever you do DON'T SUBSCRIBE TO THIS APP! You will end up paying for it FOREVER!
I've been using sleep cycle for 2 years now and haven't gone back to an old school alarm even once since. I enjoy that it's always kept interesting with new features and types of sleep aids. There is clearly a lot of continuous love and hard work going into this app. Great stuff!
Its helpful and it works well. The pleasant alarm sounds when I am in my lightest stage of sleep which makes it easier to actually wake up alert and refreshed. The app also gives tips for better sleep habits which are good reminders. I struggled with waking up early and this smart alarm made the difference I needed.
Rewriting my review 5/12/2022 to drop it another point. (See edit history.) I've been using the app to take midnight meds for over two years now. Great app, fantastic! IF 1) you sleep 8 contiguous hours, and 2) don't have a roommate. Consistently waking up in the middle of the night (e.g. to take medicine) throws off the app's time calculations, breaking half the premium features. Second, there is no way to control alarm volume, and "vibrate only" uses volume as a backup if you don't respond.
It's decently accurate for me, sometimes spikes to awake in the middle of the night, likely because some stuff fell besides the bed... Only thing I'd like to have added is an alarm based on sleeped hours, for when it's not necessary to get up early. I sometimes lay awake in bed for 2-3 hours, I'd be nice to know when I do get to sleep I'm getting enough hours!
I use it on the Samsung S 10+ 2nd gen it works great. I have used this app for abou 7 years now I was happy when ya put the distant thunder on the sound. Every once in a while it will stop the sound in the middle of playing but thats ok, I have problem with touching my phone then starting sound again. But the program itself telling me how long in bed and how long asleep and how well x i slept compared to others. Good job well done
Alarms won't wake me up. They're all too quiet for deep sleepers even at full volume. They're all pretty soft and nice sounding so they're so easy to fall right back asleep to. Please make at least ONE alarm on the free version that is worth using, otherwise the app isn't worth it.
I use this app nearly every night and it's so easy to understand. I do wish however that even on free there was a choice of 2 or 3 sounds to choose from. I'm stuck with talking which I have to turn the media volume off.
I love this app, but it REALLY needs to be able to differentiate between 2 people sleeping. Unless my partner isn't in the bed with me it will only pick up his snoring and movements . So I'm fairly certain all the data I'm getting (that I pay for premium to use for myself) is just my partners stat's. I know iPhone have a sync over wifi option but I have A Samsung and the 2 Two won't work together 🤦♀️
I loved the app for a while but then (probably) an Android update turned it into an app I can't use anymore. The lock screen blocks the alarm, which means you can't switch it off without totally waking up, perfect if you want to be upset first thing in the morning. More upsetting is the customer service - it's android, not us, we can't do anything! Hopefully some day there will be a solution! Well, I'm charged $30 a year for this app, so either make it work or don't sell it on Android! #upset
Paid user for 3+ years. Satisfied with the redesign. However I believe the alarm failed me for the first time today. It didn't ring. When I woke up and checked the screen, it showed as if the wake up time had not been reached yet. I double checked it was in "alarm" mode. Will try again tonight. edit: definitely a bug. Will file a bug report.
