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 either snooze through it or 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.

I've used this app almost every single night since I got it months ago! It's really helped me see why I've been feeling horrible every morning; apparently I toss and turn throughout the night, lol. I highly recommend this app for anyone who wants a better (and informative, even!) alarm clock, that can be set to "No Alarm Mode" if you want to just monitor your sleep on a Saturday night (or anytime when you don't have to be up at any specific time the next day). New feature like heart rate check every morning using the flash and camera to see the rate of your blood flowing through your finger is a nice touch. After a while you get to see a nice long graph of how your heart rate has been every morning. And now it comes with a step counter, and makes a graph of how many steps you have taken the past few days/weeks/months/years/however long you use the app for, and helps you see if you rest better or worse, depending on how much walking you've done that day. It's really neat.
I usually sleep until I absolutely have to get up via the smart snooze feature, so the waking up part isn't as useful as I'm sure it is for most people. HOWEVER. It's a super reliable alarm that never fails to wake me up because of the randomizing alarm sounds. It blocks out notifications while it's running in the foreground, which is awesome because my job sometimes involves people texting me at 3am for dumb reasons and if I'm asleep I don't need to worry about that. I'm also a total data nerd, so all the charts and statistics are AMAZING. I have almost 20 different sleep notes I track to see how they affect me. Being a college student it's so nice to be able to keep tabs on what's helping or hindering my sleep, because good sleep is SO important. I recommend this app to absolutely everyone. The only thing I don't like is that I have it set to take my heart rate on wake up, but I sometimes fall back asleep while doing so. That's more of a personal problem though. It would be cool if it came with the option to not stop making noise until you did your HR logging or did a simple math problem or trivia question, just to make sure you're more awake.
