  • I threw my alarm clock away!

    I’ve been using this app for more than 2 years. It’s beautiful, simple, and I love all the graphs. The choices for sounds to wake up to in the morning are all wonderful.
  • Sneaky about subscription

    By Clk936
    Pay attention. They charge you more than you think they will. It's all really interesting for the first month but then there aren't really any super useful trends or patterns to extrapolate from your sleep data.
  • Sleeping sweet!

    By LynneSM
    I've been using this sleep app for over a month now and it helps me to know how much quality sleep I'm getting. I'm finding that I want to make sure I get my 8 hours most of the time to improve my percentage of good sleep. I love this app❤️
  • Great app

    By BBHX
    Great app and super useful! Takes a bit of set up but definitely worth it!
  • Good input, wish there was more analysis

    By Mcnugg3t
    It's amazing how sensitive the app is to be able to focus just on my patterns without my husband's getting mixed in. I would like to get a better understanding of the sleep patterns and perhaps an analysis of why my results are what they are. I'm left with nice graphs to look out but don't understand what they could mean. Even the first one with the sleep cycle: I wish I understood what the various levels meant.
  • One of my Top 3 Apps

    By DutchExpress
    Helps to treat sleep like an activity that I can improve like work or fitness.
  • A+

  • Fantastically informative and helpful

    By m.ortegon
    This app is fantastic! It wakes you up with an alarm at just the right time. The choice of alarm sounds is amazing (wind, rain, etc) The sleep tracking is also incredibly informative. I only wish it would integrate to the Fitbit so you didn't have to have the phone on the bed...
  • Thanks!

    By Beastlboy
    Thank you for this app!! It's been amazing
  • Awesome

    By Bellaluna78
    This is my favorite app I have ever used, ever! I have had it for 4 years now. It wakes you up gently, you can observe various sleep patterns and adjust and the new snoring feature is also quite interesting and comical. Love love love. Cannot recommend enough.
