  • More alarms

    By Maniapp
    I give four instead of five because (1) I'd love to be able to have a few different alarms (2) it sometimes picks up my husband's snoring. I know that for a fact because I was up watching the clock when he was snoring and it registered as my snoring. Other times the sound doesn't pick up, i.e., when I'm tossing and turning.
  • Wish there was different settings

    By Mr_Snaz
    I can't always use this app because there isn't a setting that allows you to hear text messages and phone calls while the app is in use. I get that the point is for Undisturbed sleep but I am on call most nights for work and I need to hear my phone go off. Other than that I like the app.
  • GREAT I love it

  • Reliable even for two people

    By Matthias215
    My wife and I have been using the app on each of our phones to make mornings easier, and the linked-device feature works great for telling our sleep patterns apart. It even susses out who’s snoring at different times (with the very occasional mismatch). I’m pulling a star because the Hue integration does not seem to work with the (now longstanding) generation 2 hub, despite a rather old help note mentioning work on gen2 support. If they add compatibility for Hue gen2 or even HomeKit lights, it would be an instant 5-Star.
  • doesn’t have Apple Watch support

    App doesn’t have Apple Watch support which is disappointed 😔 Also I don’t see reason why can’t working with screen off
  • Great!

    By lyokolover
    I love this app. The microphone never worked for me but the accelerometer picks up movement pretty well. The only problem I have is my phone became unconnected and set off an alarm before it died. There should be some setting where you can continue the cycle instead of having to stop it. Unless there is but at 5am it was hard to figure out why it was going off in the first place.
  • A life changer

    By appleguy15
    This app makes me wake up feeling rested! I highly recommend. I do have a feature request however: allow multiple sleeps per day. I’m a college student and so sometimes I get like 4 hrs of sleep a night and then I take a nap after class and get an additional few hours. I’d like statistics recorded on both.
  • The Secret to Waking up on Time

    By sstkdoxr320
    I think I have found the perfect combination of alarm clocks. I always set Sleep Cycle to be my first alarm, and another app called SpinMe Alarm Clock as my backup. Sleep Cycle usually wakes me up in my optimal wake up time, but sometimes it just isn’t enough for me and I’ll either snooze through it or turn it off and go back to bed. If Sleep Cycle fails to wake me up, my backup alarm SpinMe will start blaring which can only be turned off if I get out of bed and spin around twice before it finally shuts off! Crazy but it works and I haven’t been late to work since I started doing this. And no you can't just spin the phone around in your hand! Sleep Cycle really does help in waking you up during your light sleep. I can feel it working most mornings. And I have studied the science behind sleep so I can attest that the premise of this app isn’t merely a placebo, but something that has actually been proven. However the problem that this alarm clock doesn’t solve is that sometimes (especially on nights where you get very little sleep), it can be really easy to ignore your alarm clock and really hard to wake up. That’s where SpinMe Alarm comes in, an alarm clock that is impossible to ignore and forces you awake. I highly recommend using these 2 alarms together. Best few dollars I’ve ever spent!!

    Shake to snooze seems to be malfunctioning. Very disappointing. Please fix this. Thanks! 🙂
