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.

  • 1,920 nights strong!

    By Biggestofdaves
    I've used Sleep Cycle for 1,920 nights and I really love this app. I enjoy reviewing all the data, it even adds location, so you can go back and see how you slept while on holiday. It also has a white noise feature which is a must for me. Developers - once the alarm is set, there's no way to go back and look at the statistics without canceling the alarm. Could you add that feature?

    My health is so much better keep track of my sleep pattern
  • Fantastic app!

    By Kizzy J
    I have been using this app for years as my go-to gentle alarm. I love how it tracks your sleep, saves lots of data, and shows you statistics. It's fascinating to see how my sleep is connected to phases of the moon and activities I did that day, etc. I did have one issue with the app shortly after it switched from gryoscope to microphone, and that is that it didn't seem to go off at all during the time I set it for, and I ended up oversleeping and missing class. But perhaps that was a bug that got fixed or my own error, since that didn't happen again (I wrote a review about this and am updating it now to 5 stars). I would like to see even more data and especially would like to download the data as a .csv file to manipulate and examine myself.
  • Still picks up Background noise outside room.

    By Lives near Disney World
    If I turn up the volume the whole way I can hear noises from family outside my bedroom door moving around. Thought it was supposed to cancel those in snoring or noises I make but it doesn’t oh well nothing is perfect in all apps on the market. Still love the app why 3 stars but outside noises gave the app 3 star review. Thank you for inaccuracies in tracking sleep once again said I barely slept last night and I was clearly out soundly because I remember all my dreams were and when you are dreaming you are deep sleep in 3rd and 4th cycle of your sleep cycle.
  • Really love the app

  • Update Bugs?

    By Spin1197
    As of the last update ... I know must fumble to enter my passcode to unlock the phone and turn off the alarm. In the last was able to do it all with locked OR maybe the phone never locked while active ... not sure. Also, I have noticed the notifications, while muted, light up the phone which of not entirely asleep and be bothersome amount of light if the screen is not manually dimmed. This is all via the iPhone X with magnetic charging so the screen now faces up in stead of down like in the past.
  • Turns music off after setting alarm

    By Hi, I'm Kyle
    Whenever I set the alarm, my music gets shut off. Then my Bluetooth speaker doesn’t get found. Once I turn off the alarm, Bluetooth speaker works again.
  • Not Happy

    By myopinionz
    Could make it easier to cancel, but I guess that’s the point. :(
  • Love it

    By dcriadoc
    It does wakes me up when I’m out of my REM, I love it! You still feel like staying on bed for a little longer but at least, You don’t feel as tired compared to when you set your regular alarm.
