  • Crashes

    By MMc?
    Been using for years. Update regularly. Will no longer run. When clicking Start it hesitates then crashes. Completely inoperable. And I have premium version. So disappointing. This had been a favorite and reliable app.
  • Awesome app, need heart rate working

    By The8ug
    I’ve been using this app to track my sleep for almost 6 years - it’s simple, and it’s effective. One of my favorite features was the heart rate monitor in the morning. Now with the iPhone X, the heart rate functionality is near impossible to use - I have yet to find a way to position my finger over the camera lens in order to calibrate and measure my heart rate. PLEASE look into this problem - I would love to begin using again!
  • Used to be good - long term user

    By Setsunai
    Hate the fact that you cannot set a volume level, it is said to increase volume to max over time. I can’t even turn off the alarm when the device is faced down even while trying to tap and waking up the phone.
  • It has been always good but is not now

    By Onelovehj
    I’ve been using this app for many years without an issue. But after I got a new iPhone x, it will not measure my heart rate using my iPhone x camera with this app. It was fine with my previous iPhone. I have no idea if this issue is because of iOS or the app. This app tries to take the heart rate as soon as I place my fingertip on the rear camera, but then shortly it fails and asking me to place my fingertip on camera again. I kept trying for several times but never worked. I hope the developer provides the solution here..
  • No watch support

    By SmokedOutDre
    Come on really no watch support? I refuse to re-download because of this.
  • Love this app

    By MakanAhmadi
    Love this app I’ve been using this for years now. Great alarm works everyday. Just got the new iPhone X and I love how you guys did the app. One thing I’ll add is if you could make the screen dark when using a wireless charger because I can’t charge it when it’s face down.
  • Heart rate doesn’t work on iPhone X

    By thebluepotato
    I use this app daily and I love it. However, on the iPhone X, it seems it always fails to register my finger when attempting to read my heart rate. It doesn’t work on your dedicated heart rate app either...
  • Update!

    By Krloom
    Update for Apple Watch, please!
  • 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.
