  • Functional

    By Fmrkdaddy
    This works and tracks sleep pretty well. I dislike the cost and also the premium sleep sounds are a bit ridiculous. Happy sleeping.
  • Love the app but didn't want premium

    By The Duncher
    I love this app, however if you don't want to pay for premium don't use their free trial. I started the trial to see if my iPad would work better than my FREE android phone app of the same name and same developer. However I promptly forgot to cancel the subscription and after I was charged could not find out how to ask for a refund and cancel the subscription. The developer and Apple have fixed this now.
  • REALLY...

    By Rycm 1
    29.99 a year for premium? A YEAR? That's terrible? If you guys switch it over to a one time payment of anything. Even $50 or $100 people would buy it. But a yearly rate for an alarm clock is so bad and almost upsetting. Please rethink what your charging people, it could really change the amount of money you make from this app in a good way.
  • Really helps with wake up

    By Scott121gerrish
    I can tell the difference in how I feel when it wakes me up closer to the top of the cycle. Does not miss on hard wake up though
  • Good

    By Dr. Dan K The Daytripper
    Wish more premium features were available for free, like the alarm noises
  • Latest version is phishing...

    By Donut_iP6_01
    Immediately after launching the latest version of the app, it asks for my iTunes account password. No app should ever ask for that, only access to microphone or camera or other privacy items. Instead, it’s using a technique documented by Felix Krause. I just renewed my annual subscription too, now I want a full refund.
  • Extended sleep the same day.

    By chet134
    Love Sleep Cycle. Wish I could continue the same night sleep when I do not hav to wake up after my assigned wake up time. Or afternoon nap. Just saying you should build in that option.
  • Pretty good, not sure it’s $30 good

    By Mamaursula
    I like being able to track my sleeping patterns, I have a very stressful job and have been working to offset the stress with measurable interventions. I have only used this a couple weeks so I’m not sure this is a metric that will help but I know I’m disappointed in the pricey additional apps and the sizable yearly cost of this one. Time will tell if I go premium or not, but I have some reservations.
  • Ooooh

  • Excellent app for tracking sleep

    By Ruralcindy
    I use this app for monitoring how much sleep I am getting, but it is excellent in several other things also. Do you ever wake up and still don’t feel rested? Do you ever wonder why? Do you sleep alone and wonder if you are snoring? Do you wonder if you just had a mild bad dream or two or were you tossing and turning all night like it felt? This app can help you answer those questions. It has a microphone that monitors your snoring, when, how much, for the premium you can even hear how you sound. It also monitors the depth of your sleep, maybe you got 8 hours, but never went into a deep sleep, still waking tired. It monitors your sleep cycles. It gives you an average of how much sleep you are actually getting. AND it actually seems to do all those things it said it would. I have found this app remarkable
