  • Love knowing that I snore!

    By aaamy2013
    I love that this app tells me exactly how many minutes that I snore every night (about 15). I wish that it had a better snooze though that allowed me to change the snooze time frame to be an hour later or so but otherwise really really love the premium features of the app. So worth the investment.
  • Brilliant but issues

    Let’s start with saying I love this app, it’s great it gets me up on time happily and it’s so useful. That said, a month into my year long subscription it asked me to renew my membership, knowing full well I payed for a year in advance I have yet to renew any thing and most likely will not. Great app, faulty subscriptions

    By 013ja
    This app charges you with a yearly subscription without any warning!!! They charged me $30 even though I barely use it, and I was not informed ahead of time. I dont recommend.
  • Omg!

    My wife and daughter sleep in the same room with me and I think sleep cycle picks up their breathing too.
  • Best sleep ever!

    This app is awesome!
  • Decent app.

    By MikeGator
    I’ve been using it for years. I think it would be great if they did a few things: 1) Redesign the analysis to be more colorful and informative. 2) Fix the current weather bug. 3) Make it usable for the AppleWatch. Every other sleep app is doing this and the most premier sleep app seems to be ignoring it. Time to bite the bullet and let us use it in our watches! Bonus: If they can work with Apple to add additional metrics to the Health app. That would be powerful!
  • Great... when it works...

    By Kate234
    I love this app, but it’s recently stopped working reliably. I contacted the developer, and it’s a known issue. Be sure to have a backup alarm. Hopefully this gets fixed soon...
