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.

  • Help me out a lot

    By saadawi abd
    Ich still Experimenting but it’s a positive influence on me
  • Improved my perspective on sleep

    By StellarBoomerang
    Being able to visualize the quality of my sleep has made me much more conscious of it. While I don’t know that my sleep quality has gone up since using this app, I have made sleep more of a priority. Being more aware makes me more considerate of sleep and that alone is worth five stars.
  • My sleep

    By Momo4rowdy
    Was way accurate in the beginning. Now that they want me to buy in I see a lot of different readings all over the chart
  • Going to Bed on Time...

    By Sleepy Cheryl
    I find the sleep app to be most interesting. It encourages me to go to bed on time, and get at least 8 hours of sleep. It also encourages to think about what I am doing before, such as nothing too simulating to avoid me from resting. Last, It gets me up within a certain range each morning. How? By not allowing me to stay in bed to long. Many Thanks, Mrs. Clay
  • Awesome app

    By PoloBlk
    I’ve used this app now for a few years now and I can not see myself using any other type of alarm. The 30 min wake feature is by far the best. I hate they’ve begun charging for extra features, but they’ve gotta make money too right?.. 😃
  • Update

    The best thing ever was when you integrated the Apple Watch with great features like silent wake. But now I can’t find any of the watch settings or features... the only thing the watch can do is set the alarm and remote snooze. The watch doesn’t vibrate or make noises anymore. What happened!!!
  • Imma keep it real with u cheif

    I don't write reviews on anything but this app is really nice. The default Apple alarm sound honestly gives me anxiety and just makes me annoyed to wake up in the morning. The sounds to choose from are so relaxing and refreshing in a way. And it gradually gets louder as the time gets closer. I probably wouldn’t recommend for heavy sleepers because the noise is light but I’ve never had any troubles sleeping through an alarm and I’d consider myself a moderate sleeper. But yeah super cool app and it tracks your sleep pattern so that’s cool too.
  • Used to be a great value

    By thpxfek
    This WAS one of the best sleep helper apps on the market years ago. That was until they went away from the free/paid version to a free/subscription model. I was a supporter of the app when you paid for it outright once and got all the premium features. When they switch to the subscription model they magically lost my info and the fact that I paid for the app all those years ago. Really disappointed in the business model they choose to adapt.

  • Snore stopper

    By laryn27
    I got this app for the “new feature” snore stopper but I can’t seem to figure it out. It did record my snores but my IWatch did not send me a lil nudge to notify me of my snores. Help!!!!
