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.

  • Needs Apple Watch improvements

    By Zxvvnn
    Love the iPhone app but drains my Apple Watch battery by at least 50%.
  • Worth the download

    By Cramer Smash
    I’ve been using this for a year and love it. Only caveat- ALLOW BLUETOOTH CONNECTIONS PLEASE!
  • I'm a believer

    By Lczchaos
    My husband told me about this thing and I was like, "Whatever." Anyhow, I finally tried it and it did improve my sleep experience. Give it a go! I especially love going to sleep to the sound of the rain or other types of white noise on here. My husband has terrible sleep issues and needs some sort of noise to fall asleep to. I prefer this over a TV.
  • Great ap

    I love being wakened gently at a good time in my sleep cycle. Now I don’t have groggy cranky days. Love it!
  • Works great but developer is coasting

    By Matt from CSM
    App is great, still works as well as it did 5 years ago. My big complaint is the developers are coasting and adding minor improvements like watch apps instead of basic but core additions. Let us have selections within the sleep notes (did/did not have caffeine, instead of having to create two separate notes. Had 1/2/3 cups of coffee, etc.) And the analysis is one dimensional. No correlations between sleep notes either. (When you have 1 cup of coffee *and* workout, you sleep 10% better). As is, app is fine, no complaints. But there’s complacency. And how about an edit button to change sleep notes without having to cancel and restart everything? Have you never fat fingered a key before?
  • Alarm going off

    By Peachbear 27
    I am changing my review and rating since I started having some issues with an alarm going off at 3:30 yesterday July 9 and today the 10th at 2:30 yesterday my alarm was set for 5:30-6pm not 3:30am so I turned alarm off and it went off at 2:30am The alarm I set are not going off but this annoying beeping sound is going off. Does anyone know how to fix this? I like the future but I am getting close to deleting app.
  • Amazing until recently

    By memes memes nothing but memes
    I’ve been using this app for over 2 years and I have loved it, it’s been super helpful and I love the way it wakes me up. However recently the alarms haven’t been going off and I have been left in the dark to then rush off to work late because I slept in. I don’t know if this is a bug or just my app doesn’t work anymore.
  • Awake Gently

    By wfmagee
    Hearing a chime and knowing I can snooze before getting up is wonderful.
