Waking up made easy Sleep Cycle is an intelligent alarm clock that tracks your sleep patterns and wakes you up in light sleep - the natural way to wake up, feeling rested and energized. No need to place your device in bed - Sleep Cycles uses sound analysis sleep tracking. How it works • As you sleep, you go through different sleep phases, ranging from light to deep sleep and back again. The sleep phase you are in when your alarm goes off is critical for how rested you will feel when you wake up. • While you sleep, your movements vary depending on what sleep phase you are in. Sleep Cycle’s patented sound technology tracks your sleep patterns using sound or vibration analysis, monitoring your movements in bed throughout the different sleep phases. • Sleep Cycle finds the optimal time when you are in light sleep to wake you up in the morning, during a predefined 30 minute time window that ends at your set alarm time. Waking up in light sleep feels like waking up naturally without an alarm, leaving you feeling rested and energized. • All you need to do is turn Sleep Cycle on before going to bed, and place your device on your nightstand or close by on the floor. Continuously rated as the best smart alarm clock on the market.

  • Sleep App

    By Susan Timmons
    I love this app. It helps me keep up with my sleep patterns and I use it to show my doctor.
  • Like the app but...

    By loltoriiixx
    Honestly I like this app. I think it does a really great job without glitching and it’s pretty accurate. However I hate how slowly every feature has become a premium required featured. I get that apps like this need some kind of income but seriously?? I used to be able to play music whenever I turned it on, listen to my snores etc. and now I can’t do any of that. Really annoying.
  • I’ve used this nightly for almost two years.

    By GreeneMan98
    It’s incredible. I don’t even make use of all the features, but every morning I check my statistics to see how well I slept. One improvement I would love to see: A “countdown” when you first set the alarm to let you know how much time you have until you wake up. It seems simple to implement but would be nice to know instead of doing the addition in my head. Awesome app, highly recommend! (Also, I’ve consistently woken up easier and less grumpy from this app.)
  • Love knowing why I feel tired

    By SimplyMrsRiley
    It’s so easy to see why I’m tired some days that I sleep the same amount of time for.

    I hate not being able to do the premium. I am not doing it bc it costs money. But I love the free app.
  • Insightful

    By Seattlandy
    I find this app really eye opening. I like how it works and has intuitive features.
  • App won't open

    By Walker3
    I've used the app for 4 years and have been really happy with it. However, the app now refuses to open... What gives? Since the last update, It works great. Thanks.
  • This app will change the way you sleep

    By Rutthy_Rogue
    I don’t write many reviews about anything, but this app is worth it. Often, I have trouble sleeping, but mostly waking up in the morning. This app makes it so easy for me to get a good nights’ sleep. I can add white noise before I sleep right on the app, and can customize how long I want it for. I can log my heartbeat and sync to my health app. I can hear my snoring, see when I was in what stage of sleep when. I can input determining factors that might indicate why I wasn’t getting proper sleep. I can log my mood in the morning. I mean, there’s just so many reasons why this app is wonderful.
  • Something isn’t working

    By alex8113249
    I downloaded this with the Curiosity of knowing what my sleep cycle may look like. After downloading, it worked awesome, it was waking me at times in the morning that I honestly felt much better! After about 100 days or so it has stopped analyzing my sleep and the graph looks completely flat lined as well as it wakes me up at the set time I give it every morning so something isn’t right even though I am still doing the same thing I was doing for the first 100 days.
