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.

The Secret to Waking Up on Time
I think I have found the perfect combination of alarm clocks. I always set Sleep Cycle to be my first alarm, and another app called SpinMe Alarm Clock as my backup. Sleep Cycle usually wakes me up in my optimal wake up time, but sometimes it just isn’t enough for me and I’ll just turn it off and go back to bed. If Sleep Cycle fails to wake me up, my backup alarm SpinMe will start blaring which can only be turned off if I get out of bed and spin around twice before it finally shuts off! Crazy but it works and I haven’t been late to work since I started doing this. And no you can't just spin the phone around in your hand!
Sleep Cycle really does help in waking you up during your light sleep. I can feel it working most mornings. And I have studied the science behind sleep so I can attest that the premise of this app isn’t merely a placebo, but something that has actually been proven. However the problem that this alarm clock doesn’t solve is that sometimes (especially on nights where you get very little sleep), it can be really easy to ignore your alarm clock and really hard to wake up. That’s where SpinMe Alarm comes in, an alarm clock that is impossible to ignore and forces you awake.
I highly recommend using these 2 alarms together. Best few dollars I’ve ever spent.
Overall great app, just few changes would greatly help
I have been using this app for over a year now and I can honestly say this app has improved my ability to feel more awake in the morning without having to use the snooze button at all anymore. The app senses your movements overnight and when you make any sort of movement in the time period you set to wake up, the app gently wakes you up with a soft melody that gradually escalates in volume if you are still out cold. To my surprise when I first bought this app, I truly did feel more refreshed in the morning even when I had to wake up at 4:00am for work, so this was well worth the purchase for how well it affected the start of every day.
There are just a few changes that I would appreciate being added in the future. One would be to add a Do Not Disturb option for receiving calls or messages (yes, a little contradictory in trying to gain better sleep, but necessary in some lines of work or for family). The other change that would benefit the app's users would be to include your own custom playlist for the sleep aid since some people, like me, fall asleep easier through music rather than sounds.
Can't sleep without this APP
I have been using this APP now for over a year. It's helped me better understand my sleep patterns and change some of my life cycle patterns. The way I sleep, times I sleep and what my impact them. I added a number of options as to what happened the few hours before going to bed, which location I slept at and what meds I took. It helped me see that taking my meds too late my cause me to fall asleep later. I also use an air device and this APP showed how well it worked; when I was thinking it made no difference. Some say it may not be perfect; but I still enjoy having the ability to see and understand how I'm sleeping and if I can control something around me to sleep better. Thanks for developing a useful APP. But the way, this was my first smart phone - iphone; and this APP was the first one I purchased because I didn't want to be wasting money on APPs when I didn't understand the new phone. So happy I purchased this APP.
