    This app is an awesome app. It really works at walking me up at the best time so I am feeling like I can wake up. So many times in the past when my alarm has gone off and I wake up groggy. Not with this app. I. Am honestly say that it has worked every time. I do wish they had it connect to my Apple Watch. That would make me put a 5 star rating if and when that will happen. I would be ecstatic if they could happen.

    I love it, it tracks how you sleep and is very simple to use
  • Works very well..

    By ProbablyOverlyCritical
    So far. Have only had it a few days. Will update my review periodically.
  • Not sure this is legit

    By Bogeygolfer83642
    Only used 3 nights so far but I’ve noticed I’ll wake up in the middle of the night and take note of the time. When I look at the app in the morning it shows I was asleep during the time I know that I was awake. If it’s that inaccurate then how can I trust this isn’t just a gimmicky toy??
  • why is there no go back to sleep option??

    By Gngicyjokk
    sometimes i just need to wake up early to take medication but then i go right back to bed so i really really wish there was a way to turn the alarm off but keep tracking :( other than that i LOVE THIS APP i have the paid version and everything i’ve logged over 350 days but i’m just SO frustrated not being able to go back to sleep without messing up my stats!
  • Love this app

    By Jnevans92
    I've been using this every night for years and I find it really helps me wake up in lighter sleep and not be horribly groggy. The sleep aid sounds are nice too!
  • Love the app, hate warm breeze

    By Erik stop annoying me
    I've been using this app almost every night for over three years. It works and it's great to be able to look at the data it records. However there has been one annoyance keeping me from giving Sleep Cycle five stars: it keeps switching the song that wakes me to warm breeze, and I am so sick of hearing it. I set it to play my own music which works sometimes but it frequently switches to the boring repetitive stock music of warm breeze. I've noticed another review with the same issue and I wonder how many others have dealt with this. TL;DR Wonderful app worth the price, one minor issue with the very annoying Warm Breeze song
  • It’s good but could be better

    By DealAddict
    I wake just fine to alarms but what I like about this is that it finds the moment when I’m near light sleep to wake me making waking up easier. What I’d love to see is for the app to allow me to set it once, like a regular alarm, and don’t require me to have to start it every single night.
  • Almost perfect (no Apple Watch support)

    By Messanger for Ipad
    This app is amazing and I used it for a long time but the one thing that it is missing is Apple Watch support which could make this app even more accurate, I am Moving on to another app but if they ever add Apple Watch support, I will definitely use it again
  • Amazing app- magical!
