  • Love it!

    By sleeplessJeni
    Have had a lot of trouble sleeping and love this app for tracking my sleep. Amazing!
  • Life changing app!

    By SarSarHanHan
    I’ve been using this app for over 5 years and have logged 1800+ nights, and I would hate to have to ever give it up! My favorite feature is the alarm window (wake up phase) - it helps me wake up feeling refreshed and not groggy by avoid waking me up during deep sleep. I never want to use another alarm clock again! I also love that I can check the time in the middle of the night without the shock of a bright screen. And I enjoy the analytics that give me insights into my sleep quality and patterns. This app is worth the download!
  • Not reliable

    By Coolnbeams
    Alarm won’t sound on some mornings. I’ve set my alarm for 5am and didn’t hear a sound until I touched my phone at 7:30, at which point as soon as I opened the app the alarm went off.
  • Recently changed for the worse

    By M90815
    Don’t know what happened but recently the app stopped tracking sleep reliably. Now shows me as not asleep when I often am asleep. I am afraid that I will have to change apps.
  • Used for long time! Don't like the updated version!

    By Lovejeeps
    I've been using this app for awhile now. Loved it prior to the update! 5 stars! Just updated. Quality circle colors are so orange and bright, they hurt my eyes after waking up. It's not as pleasing to look at. Before the update, you could glance at all your results on the results page and quickly see your quality of sleep, snoring results and time of sleep. Now it's hard to see because of the colors and the shaded gray color of the label you can even see. You also have to scroll down to see summary of results. It's bad, just bad! I'm so sorry I updated the app! How can I go back?
  • Apple Watch Support Removed

    By Island Life
    I really hope Apple releases an in-house, first party sleep tracking app. Because I can’t imagine how people who are using apps like Sleep Cycle on a subscription basis are happy with the removal of features like overnight heart rate tracking via Apple Watch. This app has become far less accurate since its removal... and it wasn’t terribly accurate to begin with. If you happen to be the type who quietly lies still in bed for and hour waiting to fall asleep, the data will suggest that you fell asleep within just two minutes 😑 Would that I could fall asleep like that, Sleep Cycle. Please bring back Apple Watch support so that this app is slightly more accurate again
  • Really Expensive Subscription

    By PisceswithaPasssion
    The only reason I’m giving this two stars is because the app is marketed as if it had an abundance of cool features, but in reality, those features are only available if you buy an outrageously expensive subscription. Without buying a subscription you get the basic alarm function of the app. If you’re looking for an alarm, this is perfect. If you are looking for all the high-tech features, look somewhere else.
  • Automatically charges yearly price of 50 IT IS A SCAM

    By studentRL
    I got charged $50 for the yearly fee. It defaults to the yearly fee. Do not buy. It is also incredibly creepy on how it asks for camera and microphone access?? What the heck??
  • Tried to cancel right after(same day)- but couldn’t

    By Alskdkfjgghh
    Make sure you don’t accidentally sign up for premium trial. You can’t cancel even on the same day they charge you. I prefer my free pillow app so much more.
  • Amazing

    By marlleeyy
