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.

  • Alarm went off 3 hours early

    I love this app but that cannot happen again so I have to delete it now.
  • The OG app

    By Iblondify
    I’ve been using this app since the beginning. Sometimes I fade out from using it, but I always come back. This app doesn’t make getting up in the morning wonderful, but it makes it wildly easier. The alarm is not jarring and it wakes you up a lot more gently. I think it pretty accurately tracks your movement. Is it 100% perfect? No smartphone app is. But overall, it gives you a great review of how you slept. I also think it’s hysterical how it records your snoring. I never knew I snored up until getting this app 😂😂
  • love love love !!

    I downloaded this app on my first day of school. i have to get up at around 5/5:30. My app wakes me up around 5:27 every morning and i always feel so well rested. i always have enough time to do everything i need so do as well. I used to not be a morning person, and I would always have to be pried out of bed. I mean, who wants to wake up in mornings? not me! I still dont like getting up in the mornings, but who does? any occasion where i have to get out of bed is horrible. anyways, i learned about this app from a youtube video and i decided to try it out. it works amazing! it even tracks my sleep (when im awake, in deep sleep, and in light sleep)! i know it’s accurate because if i wake up in the middle of the night, check my clock (not my phone, my clock) and it says 1 am, i can go on the app the next morning and it will say i was awake at 1 am. i find it super interesting how i sleep. this app will also tell you the quality of your sleep. (mine’s around 65, guess that’s why im always tired lol) it will also tell you exactly how much sleep you got each night. sadly, without any costs, you can not record this data without screenshots, or manually logging it. it doesnt track it over extended numbers of nights without costs, which im not complaining about what-so-ever because this app is amazing with or without.
  • The best!

    By gracie5684lalalala
    I used this thing and it is the BEST! Unlike normal alarm clocks, this actually wakes you up peacefully. Instead of BEEP! BEEP! BEEP! BEEP! 5 stars!
  • “Most used app” list!

    By Startyger
    Easily, on my most used apps list. I want it to interact with other apps, devices and HomeKit for so much more! It has been a key to not snoring anymore and figuring out my own sleep needs. Great app!
  • Great app but it’s a battery drainer

    By Mara Moriarty
    I quit using this app about a month or so ago, I loved that it worked amazingly but even if my phone was plugged in to my charger, the battery drained or didn’t charge. Because of it my battery’s maximum capability percent went down. After I stopped using it my phone went back to normal. I prefer to use the native bedside feature even if sleep just shows as “in bed”.
  • Amazing

    By Banababababababa
    I have been using this app for about four years now, and I use it pretty much every night. It is an amazing app that continues to add awesome features after all this time. If you are on the edge, just get the app. You won’t regret it.
  • Cool app but not sure if it’s me or my partner

    By lewistherunner
    I just get results that are pretty different... I think sometimes it picks up my partners sleep instead. Also, I notice if the angle is slightly off direction, the quality of sleep is different

    Okay I downloaded this app, used it for the trial period then deleted it. Tell me why, I kept on getting charged each month, like $32!!! I was so confused and noticed it like 6 months later that I had this suspicious charge all to find out that it was this app. 10/10 would not recommend
