    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.

    The data collected is not accurate. Just because I'm in the bed without making noise doesn't mean I'm in need sleep but the app recorded as deep sleep. As a result of this inaccuracy the wake up time doesn't match the sleep cycle as it was supposed to be.

    I think that its the best for weekends and other times of stay at home and no school

    Works well. Dunno how accurate it actually is of course but I like the concept, the wake up phase, and the snooze functionality. Hasn't failed yet.

    Interesting to see my sleep patterns. Seems fairly accurate for tracking movements. Often I'll half-wake just before the alarm goes off, so it's a helpful reminder not to go back to sleep! Streamlined, easy to use design, and nice custom options for the alarm. You can't preset multiple alarms, but it's not a deal breaker. Wish it was cheaper, but free month is worth it to try.
