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.

  • Disappointed in removal of features

    By Pocketmole
    I don’t tend to write reviews but I’m incredibly disappointed in how this company handled their recent update. I totally understand that a company needs to make money, but they stripped the app of all meaningful features and put it behind a subscription pay wall. I wouldn’t have minded paying for a quality app, but $30 a year is steep. My three years of sleep cycle loyalty would have cost me $90 and no alarm clock is worth that price. I wish they had grandfathered in prior users for a discounted rate or one time purchase price. Or hell even worked ads into the interface. Unfortunately they pulled the rug out from under us and I have no choice but to uninstall. Really disappointed because over the years I had recommended it to so many people.
  • 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.
  • Love Sleep Cycle but disappointed

    By srhickman
    All the recent reviews tell the story. I’m just agreeing and adding my opinion. First of all, I’ve been using Sleep Cycle for years and have loved it. I’ve recommended it again and again. When they added snore recording it was very important to me and inspired me to lose weight. Suddenly without warning many of the features I’ve love have been taken away and are now part of the premium $30/year plan. I love the app so much I’m tempted to buy the premium plan, but I hate to encourage the developer’s tactics. Very disappointing.
  • Extortion

    By DiveDiva007
    I’ve used this app for a year. Now all of a sudden you want to hold my personal data hostage so you can extort money from me. It’s my data, you’re violating privacy laws by trying to make me pay to get access to it. You need to learn how to treat your customers! No message, no info at all on your decision to cut me off, just one day I can’t access my data unless I pay you $30! Extortion!
  • 5 Star

    By peterpay123
    I rate this app a 5 out of 5 stars. Overall, the Sleep Cycle Alarm Clock was insightful, intuitive and helpful. It helped me wake up easier in the morning, gave detailed and graphed sleep analysis and tracked your progress.
