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.

  • Bought this app a long time ago

    By RustVel
    Thank you so much for not taking away what I payed for back then. Wasn’t much but it was something. Wow.
  • Best. App. Ever.

    By alyssamc360
    Normally when I wake up I’m tired and groggy like usual, but I started using this and I woke up not even tired!! Its sp amazing.
  • Way too loud

    By Peyu39
    The volume should be configurable. It starts off loud and wakes me up immediately, getting even louder very suddenly until it’s so loud that I wonder whether anyone needs an alarm that loud to wake up. I need to fumble to turn the alarm off so I don’t disturb others. My wife’s app does the same thing, it’s not a version or restart issue. I’ve had two phones and many app updates in between and the issue’s been here for months. The fix is simple and needs to come from developers: The sound increase should be much more subtle and that the min and max bounds easily customizable for light or heavy sleepers. The snooze feature is also terrifying because it’ll blast off at a high volume instead of slowly increasing volume from the minimum like I’d hope.
  • Unfortunate

    By dlcneisksn
    I’ve been using this for years. Then last week all of my data was gone. I had none of the features I’ve always had. Everything was locked away & any of the features are blocked unless you pay money. Such as disappointment that you can no longer get ANyTHINg unless you pay.
  • Free App vs Premium App

    By asedt12
    I had this app when it first came out. The app I had stored recordings of the snores and it was free at that time. Now I would have to pay for the premium app to hear the recordings. I enjoyed the app more with the free recordings.
  • Disappointed

    By Eapatches
    I used to love this app, but they suddenly changed all the features to premium and want to charge me $30? Kind of shady.
  • Loved it, until the latest release

    By thekruser/4sqGuru
    I’ve been using Sleep Cycle for years. I absolutely love the program. However, with the newest release it no longer plays my chosen sound as I fall sleep. Now that is a “premium“ feature. I realized this review will have almost no impact. Still, I find it pretty crappy that after all this time now the standard features are becoming premium ones. I have stopped using me up now. There are plenty other applications out there that do the same thing. It is a shame to lose those years of data. Still, I will not be strong-armed into paying for something that was at one time a standard feature.
  • A little annoyed

    By selenium31
    As many other users have stated, I also have been using this app for years! I’m so upset that over 5 years of data are just gone. I used all of the features that now can only be used through paying and I will also be looking for something else and if anything just using the sleep tracker on my iPhone. Really disappointed with this change.
  • Best app ever!!

    By Goodland living
    This has helped me sooo much!! I struggled with continues waking up at night and would wake up soo tired and wondered why I was so tired. Until, my co worker told me about this app. I have my 17 year old daughter using it and my husband now my sister in laws are using it too!! This is my best friend! I wake up so refreshed and love all the reminders!!
  • Awesome

    By reviewer4508
