    An intuitive way to wake up.

    • It works
    • Cool graphs and charts
    • Smootha app performance
    • It doesn't work for everyone
    • It needs some variety

    "What Is Your Sleep Cycle?"


    Sleep Cycle alarm clock provides an intelligent option for waking up in the morning. Who wants to wake up to that annoying buzzer? How many times must we slam our hand on that 'snooze' button to extinguish the jarring sound. Sleep Cycle alarm clock provides a calmer solution.


    The graphs and charts really add to user engagement and create a better learning experience. Being able to customize your wake-up song is a nice touch. The gradual way it wakes you up actually works. The app performs well and menu transitions were smooth and flawless.


    It may not work for everyone. It could use some additional variety. It froze on one of the screenshot images.

    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. Featured in: CNN, Wired, The Guardian, The Wall Street Journal, BBC, The New York Times.
