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.

  • 👍🏽love the app...

    By Tori😊❤️
    love the app and it has helped me track when i wake up in the night. i got this app because i was curious as to how i slept. 👍🏽
  • Pretty good

    By MeganG.
    It was a bit odd, and I would prefer more detail but I enjoyed the app and might even use it again!
  • Disappointed

    By campanaff
    Long time user, first time reviewer. I’ve been using this app for years and it was great. I thought losing sleep sounds was a glitch until I realized it was due to an update. So now I have to be a premium user and pay a fee to use sleep sounds? I’m very disappointed.
  • Love the app! Bedtime would be nice feature!

    By Shaun Mosley
    Would love a scheduled bedtime feature. An Android app (Sleep as Android) had that feature and it was a nice evening reminder that I need to work my way to bed.
  • I really like it

    By Lilaanne122
    I really like how there are no in-app purchases that you absolutely have to get to use that app and I also like how you can change the sound and it wakes you up gently so you aren’t groggy in the morning. I mean, it reduces the groggy-ness, but you know. I am in love with this app, five stars! Hope you also like it! With pleasure, someone writing a review on a sleep app.
  • Frustrated user

    By Lfranklin99
    I’m been using this app for years and suddenly, without warning they make all the data tracking features pay only and I lost all of my data. Going to go ahead and look for another app. So disappointed. It honestly felt like a big, screw you.
  • Used to be great...

    By tozerfan
    Until they limited my use of features all of a sudden.
  • Not worth it if you have to pay a recurring fee

    By Curtisjay
    I’ve had this app for years and have generally been happy with it, but I’ve never cared for the extras that they want you to pay for. Now they’re just charging everyone an annual fee to use the app for its intended purpose. I’m not willing to pay an annual fee for this app, it’s not worth it to me, and it feels like a slap in the face to a long time user that they’ve suddenly made this change. For anyone considering this app, this should be very telling. What will they do next when the profits aren’t meeting their expectations?
  • I was skeptic at first, but it actually works!!! 🎉

    By jp-hr
    Honestly, I thought there was no way on Earth this was ever going to work, especially since there is nothing but my (and other people in my room) breathing pattern that it’s tracking, which I thought was pretty unreliable... But let me tell you that I have never woken up feeling more well-rested than whenever I wake up to this app! Amazing 👏
  • Recent bugs

    By TheOneTheOnlyBrandon
    I’ve been using this app every night for over 5 years. It’s my go to alarm because most don’t wake me up. However, in the last few months there have been bugs that have been a real problem for me. First of all, it keeps resetting my alarm tone. I set it for one of my songs, and then whenever it feels like it, it switches to one called “Warm Breeze”. This tone is way too soft to wake me effectively, and I’ve slept through it multiple times. It’s also repetitive and annoying so it’s not the first thing I wanna hear in the morning. Another thing that the app has been doing is sometimes allowing the phone to go to the lock screen sometimes for seemingly no reason. It is plugged in and face down just like it is supposed to be. When it does this it also tends not to play my alarm tone, and it will play another annoying stock tone. Also, not a bug, but it would be nice if I could use songs from Spotify for an alarm instead of from my music. I have very few songs in my music anymore because I use Spotify, so I have very few options for alarm tones other than the annoying stock ones.
