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

    By Eapatches
    I used to love this app, but they suddenly changed all the features to premium and want to charge me $30? Kind of shady.
  • Loved it, until the latest release

    By thekruser/4sqGuru
    I’ve been using Sleep Cycle for years. I absolutely love the program. However, with the newest release it no longer plays my chosen sound as I fall sleep. Now that is a “premium“ feature. I realized this review will have almost no impact. Still, I find it pretty crappy that after all this time now the standard features are becoming premium ones. I have stopped using me up now. There are plenty other applications out there that do the same thing. It is a shame to lose those years of data. Still, I will not be strong-armed into paying for something that was at one time a standard feature.
  • A little annoyed

    By selenium31
    As many other users have stated, I also have been using this app for years! I’m so upset that over 5 years of data are just gone. I used all of the features that now can only be used through paying and I will also be looking for something else and if anything just using the sleep tracker on my iPhone. Really disappointed with this change.
  • Best app ever!!

    By Goodland living
    This has helped me sooo much!! I struggled with continues waking up at night and would wake up soo tired and wondered why I was so tired. Until, my co worker told me about this app. I have my 17 year old daughter using it and my husband now my sister in laws are using it too!! This is my best friend! I wake up so refreshed and love all the reminders!!
  • Awesome

    By reviewer4508
    This is awesome I just don’t like having to be a premium
  • Overall Quite Good

    By Great and smooth
    Other than the fact that I think the default sounds are pretty annoying and the fact that my sleep cycle wakes me up at either the very beginning of my 30 minute wake up time or it wakes me up at the very end of it I would definitely recommend this app. Although, unless you want more ringtones and a few more options in settings I would not recommend getting the subscription.
  • Gentle wake up

    By Vegiegal
    I've used this app a few years and love how it gently wakes me. It is so much better to start the day with this than the sudden loud jolt you get from a regular alarm! Unfortunately after years of giving this app 5 stars I had to downgrade my rating because they are now charging an annual subscription for basic features they have included free for years. They gave users no warning about this so I lost all of my sleep data. Very disappointed.
  • Sooo good

    By Yoshi 201
    This is so cool I could sleep and then wake up to music and it’s the great you don’t know what’s going to happen! I have to get a app just like it! I love it 😊 !
  • Fascinating science

    By dubdub52
    It’s so cool and it works. So basically it tracks your sleeping and then wakes you up when your sleep cycle is at a a high pint, when you’re restless so the waking up process is more natural. I was skeptical at first but I have never felt better in the mornings. Very well done, thank you!
  • You guys should make it so you can listen to your snoring without paying money.
