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.

  • Crashes after update

    By Darkmeat
    Will not start anymore, please fix! New update but still crashes immediately
  • Turns volume down every morning

    By noahsam
    Love what this app does for me sleep schedule! Sadly it now turns my speaker/ringer volume down to zero every morning after turning off the alarm... I hope the devs can find a solution!
  • THE BEST sleep app, now with Apple Watch support!

    By Jason Pruitt
    Best app I've ever used. Developers are truly cutting edge. Now with Apple Watch support, it’s absolutely perfect. A must download.
  • Buggy and price, but has good features.

    By KevinJEdwards
    They need to fixe the bugs, especially launch bugs on the Apple Watch and lower the price. $30 a year is way too expensive.
  • Used to love it

    By Mehershe
    Unfortunately I will probably not use it anymore since on my iPhone I have missed to many important notifications (texts) due to no sound coming through when the app is running! Why did this change it is just the worst about the app!
  • Do not buy this app

    By rahulnaamtohsunahoga
    I bought this app thinking it will provide good analysis about my sleep. Within a year they started premium subscription and all the analysis is available to premium members only at a cost. I wish I could have given them half star.

    it’s a pretty sick app bro, it’s organized and fun honestly just to like look at dude. if you’re interested in tracking your sleep in any way or just need an alarm clock, this app will work for you man.
  • Very cool

    By rieksofjnek
    It’s very cool to see my sleep pattern. I wish it would calculate the amount of time in each sleep holding (ie deep sleep) so I know whether my time spent in there is average/more/less. I would definitely recommend!
  • Good app for tracking sleep

    By TechKitten
    I’m giving this a substantially lower rating than my previous review because a recent update changed the behavior so that I’m forced to use an alarm now even though I don’t want to, worse it forces one to also use notifications as a ‘backup alarm, when all I really want to do is track how well (or not) I’m sleeping, which this used to do well. I do NOT need or use an alarm so this requirement means I’ll be deleting this formerly great app and start searching for a replacement.
  • Needs HR incorporated in graph

    By ktchaskel
    I like the app but wish there was a way to incorporate HR from Apple Watch into graph.
