Sleep cycle is continuously rated as the best smart alarm clock, Sleep Cycle is now the worlds most used intelligent alarm clock.
* Sleep Cycle monitors your movement during sleep using the extremely sensitive accelerometer in your iPhone.
* 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 iPhone 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 iPhone 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.

News in Sleep Cycle 4.4:

Fantastic app that just keeps getting better!
**edit to original 5 star review (below)** Dear Developers: Please design a new feature that allows you to choose "go back to sleep" when you wake up. (I just now woke up and picked up my phone and touched the screen to see what time it was only to accidentally turn off sleep cycle. So sad!) Or if we could choose to combine two sleep periods that would fix the problem, too. There are times when I've gone back to sleep for an hour or so after the time for which I originally set my alarm-- it would be nice to be able to combine two sets of data. Thanks & keep up the great work!
Absolutely love this app. I have been using it almost every night for the last 3 years so I've seen it go through many transformations. What was simply a movement monitor avoid waking you during deep sleep, now also allows you to integrate sleep notes (notes about your day) to correlate them with sleep quality. Most recently they have included an option to test your heart rate in the morning, and are incorporating "activity" which is automatically tracked (both iPhone 5 or later). While this particular note hasn't quite been refined yet (I don't always have my phone on me so this will be an underestimate for a lot of us), knowing these guys it will be soon! I highly recommend this app! Especially to people who like data :)
To the developers: Thanks for all the hard work and wonderful app!!
I have used this app for about 190 nights now and I enjoy the graphs and data it offers you. I never really had problems getting up in the morning like some people so the variable alarm time didn't drastically change my morning well-being like I hear it does for some folks. Sometimes when I wake up I feel like I'm trapped - if I make any slight movement it will go off and I will have to get up...
At best for me this app is a nice alarm with many more features than Apple's app with some nice default alarm sounds. The data is cool to see but doesn't really give me useful data that I can use to change my habits. Still, for the price it is at the very least a fun experiment to test on yourself, maybe to learn a bit about what helps your nights go by easier. I will continue to use this app every night when I can. Other reviews mention some needed features such as napping accommodations and the ability to edit notes (when I'm tired I tend to forget to click them all) and maybe a "continuing the last night" command in case you only used the alarm to get up for a moment before sleeping some more.
Nice App but needs some tweaks!
GREAT ALARM CLOCK/SLEEP ANALYSIS APP!! I Love this App, I've used it for a couple of years, and I've had trouble getting "enough sleep", and this helps me really see how much I'm getting or lack there of. I am ecstatic over the "New" Resting Heart Rate Monitor, that measures your heartbeat as soon as you shut off the alarm. VERY COOL, & as an athlete that's important to me!! Unfortunately this app still needs a few tweaks: 1)The Sleep Notes are "Way Off"base, and there's no way to adjust them. :( 2)The app picks up when I toss & turn, and also if my hubby gets up, so it's not always accurate. (We're in a queen size "sleep #" bed). 3) I would LOVE IT if there was an option to let your "SLEEP SOUND" PLAY ALL NIGHT, espec when you're traveling, b/c this could block out unfamiliar sounds) and maybe "fade off" near your alarm time? 4) Last but not least, on one of those rare times where you have the option to go back to bed "After" you've shut off your alarm, it would be great if you could "resume" your sleep w/out messing up your sleep data, in other words "connect" the same data for the same day! Thanks for an otherwise Great App! P.S. I love the variety of sound options!
