  • Great app.

    By BoundTogetherForGood
    I have sleep apnea and I sleep very hard. this app has been extremely helpful to me and my schedule. I would recommend.
  • My love ended Monday

    By MiJun80
    I have loved this app and used it for almost a year. I stopped setting back up alarms about 6 months ago. Until Monday morning when i woke up late for work. The alarm didn’t go off and the app appears to have shut itself off. I tried again the next night, it did it again. Today, sadly i deleted the app after not being able to contact any support.
  • Used to work really well

    By Nandan RP
    I’ve logged 1300+ nights with sleep cycle. I’ve successfully used it on multiple iPhones, including the iPhone 6, 6S, 7, X and now XS. For the last month or more on my XS the app stops monitoring sleep in the middle of the night and does not perform the “gentle wake up” that I’m used to in the morning. I have no idea what is causing it to close nightly requiring the app to be reopened. Very disappointed after so many years of use.
  • Dangerous Update

    By Gargamel-12345
    Apparently a recent update has silenced all notifications, including low glucose alerts from my type 1 diabetic son. One seemingly minor update has shifted this app from great to dangerous. Shame they didn’t mention that change. Shame it’s not an option you can turn on/off. Lucky we caught him tonight. Hunting for new alarm clock app tomorrow.
  • Keeping my friends up at night

    By Innymoozlim
    This app claims to help many, but in fact it just keeps my friends up at night waiting to go to sleep to achieve perfect REM-ness. It’s ridiculous I tell you. Absolutely ridiculous. My friends delay sleeping for hours on end to follow what this useless, pathetic, and figgity foogity fudgy app says. If this app does not shut down within 30 days I will write a strongly worded letter to the president about this.
  • Forced to pay for Premium now..

    By Megan H
    I have been using this app for ~5 years. Previously, I was able to view my sleep trends without having to pay for Premium subscription. Now, they force users to pay to upgrade to Premium to view any of their sleep trends. I’m incredibly disappointed, as I have been enjoying this feature for several years. Unless they make the same trends available for free as they once were, this app is essentially useless. I’m currently searching for a new sleep tracker app.
  • Love this app!

    By lilymayy
    This wakes me up everyday. Even on trough days when I’m tired. I highly recommend this and love using it, it’s easy and simple to use and helps me understand my sleep and if I slept for a good amount. I’ve recommended to all my friends. I didn’t buy premium and still works good. I’ve used it for probably over a year by now
  • Do not update

    By -$&6SR
    Do not update if you are on an older version. They have reduced access to what were great aspects of the app unless you upgrade to premium for a cost.
  • Not accurate in the least

    By DJMajickMan
    Doesn’t include my waking to pee and being unable to fall back to sleep for an hour. Just records the time you’re not using your phone.
  • Apple Watch Battery Drain

    By DB1541
    This 1-star review applies only to the Apple Watch version. I tried it on my old watch a long time ago and it completely ran down the battery from 100%. Figured it was more about the old watch. Tried it last night with a brand new Series 4...and it ran it completely down as well. Hope they can fix this issue.
