  • Just what I needed

    By ~ Happier, healthier me
    Sleep studies and statistics confirm our need for 7.5 to 9 hours of sleep every night to be healthier, feel better and be the MOST productive! Sleep cycle app not only helps you to get the sleep necessary but it wakes you up gently and only as you are coming out of a sleep cycle just when you are ready to awaken. You will wake up refreshed and be ready to take charge of your day instead of your day taking charge of you! It is a fabulous tool to help you understand your own sleep cycles and habits so you can improve your sleep for a healthier, happier life! ~ Marsha
  • Latest update

    By K_Forbes
    Like other users have already commented, the latest update has caused the alarm to not function effectively. The volume of the alarm, even when turned up full, is hardly loud enough to be heard. Three nights in a row, I overslept the alarm because I couldn’t hear it. Also, the snooze feature requires you to pick up the phone as opposed to before when you could just tap it. I liked the previous snooze feature, though other users may disagree. Please fix these issues ASAP! Other than that, I have been using this app for years and have loved it. Helps me wake up more intuitively. I especially like the data tracking so I can see what affects my sleep quality and adjust daily habits for a better night’s sleep.
  • New Update 👎🏼

    By SwiftGrammer
    The app has not performed well since the last big update. One night it completely crashed and the alarm did not go off in the morning. Last night it completely drained my phone’s battery, even when plugged into the charger. Won’t be using the app until it gets updated again.
  • Helps make sleep a priority

    By Elizabeth Bercaw
    By tracking my sleep, I’m already placing more importance on quality sleep. Getting to bed earlier, and winding down sooner.
  • Alarm stopped being loud enough to hear after last update

    By SuperSonia2
    After the last update the alarm volume went really low even though it was still set loud. It didn’t wake me up. Not helpful. If this alarm can’t wake me up then it’s pretty useless.
  • It’s great, but...

    By Floating narwhal
    This app has a lot of functionality, except when it comes to the alarm sounds. Why does the app only allow you to pick songs from apple music? Why can’t I use music from other platforms to wake me up? To me, the appeal of the premium membership came from the extra options, but they really limited themselves in that area. What good is the 30 bucks a year if I have to have an apple music subscription, which would be another 120 a year, to wake up to the music I want to hear.
  • Great

    By bry4r
    It’s honestly, hands down the best alarm app. The peaceful noises, the helpful tips. Just download it and see for yourself.
  • App needs to be fixed

    By Anonymous 220
    I’ve been using this app since 2012, and it has been excellent. The new update has made it unusable. It doesn’t wake me up anymore. Please fix this as soon as possible. Thanks
  • great job on the battery usage!

    By drgonz86
    With a recent update the battery usage went down to only 20% for full night of tracking with microphone (iphone 7), including listening to a 1h podcast while falling asleep. Awesome! Now I no longer need to use my old 5s for the podcast just so the 7 can be plugged in.
  • Excellent sleep app

    By Jrburns360
    Collects very good data. Haven't used the standard alarm in a while. Alarm wake up alert wakes me gently. Ability to snooze, and set sleep notes is tremendous. Available charts really help me understand habits that help or hinder good sleep. Awesome app so far. Installed on my previous Note 4, iPhone 6+ and now on my iPhone 8.
