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.

  • Very disappointed

    By eyeswideopen03
    Recent update ruined the app. I’ve been using this app for years and now with the update all my data is lost and I can no longer look at my sleep trends. And to get it back I have to pay $30?! The worst part is that the update description didn’t indicate that this change was coming. Definitely a shady tactic from the developer. Deleting this app for sure.
  • Definitely a great alarm clock!

    I can’t say how much I’m glad to find this app after many nights of struggles in finding some good sleep.
  • Love it

    By Nana_88 16
    I really like everything that the app offers the one thing I can say is I have a weird schedule and I want to monitor my power naps. This app helps me figure out how to get more rest and I use it with life cycle
  • A MUST-HAVE APP: I no longer wake up tired

    By this is a review...
    The sleep cycle timer has drastically improved my energy in the morning because it wakes me up within a time window based on how deep of a sleep stage I’m in. I never use wake up alarms now, I rely on sleep cycle. It collects data which is interesting to analyze, although most of the data on my quality of sleep was already pretty intuitive. I do appreciate that you can track certain habits and how that might affect your sleep (I.e. drinking coffee in the afternoon, or watching TV in bed). A MIST HAVE app!
  • Wonderful

    Convenient and easy. Keeps track of snoring!!! How fun!

    First they made you buy the premium app for extra features. Now, they took away the extra features and are making you subscribe for them. Get a free white noise app instead and use it with your Apple bed time features.
  • New changes

    By Brandi D.
    I loved this app until yesterday when it updated and now I’m required to pay to get any of the services I’ve been using. No more recordings and no more white noise. I will likely search for a new app or white noise machine, as that was a large reason I used it. Also, you should have the ability to have noise all night, though I think the accuracy is off with the sound on.
  • Watch app issues

    By Happycard2
    I decided to not keep app after I installed on my watch. The watch app does honor the “ don’t show on watch face” setting. And when the app is deinstalled from the phone is does uninstall on watch. Apple Watch OS 5.01. Tried restarting the the watch.
  • Features taken from free to premium only :(

    By alex2010
    I have *never* reviewed an app, but I’m so annoyed by all of the features that USED to be in the free version that are now only for premium that I had to say something. I’ve been using this app for literally years and have loved it and found it so useful. I would say 5 stars absolutely. Now so many of the features that I found useful - sleep aid sounds in particular - are only for premium? What? Talk about annoying. Only the VERY bare minimum is now available unless you’re willing to pay $30 for an app which I am definitely not. What a shame.
