Now it doesn’t work with my version of IOS 13 and I need it fixed 😩 ### 5/5 — Please fix and update!! *2017-03-12* I love this app and have for a very long time but it desperately needs updating. It takes forever to open with as many as 10 or 12 attempts. I need my good night app Please fix ### 1/5 — Views 1 day, History Blocked *2016-09-24, version 1.2.10* I used to be able to see my sleep history, but now it's blocked by an add that says you need to purchase an upgrade. I'd happily do so, but it doesn't allow you to. It's stuck in a loop, thinking, and never advances. Ever. At all. So history is inaccessible. Being that if you grab your phone to see what time it is, and the app shuts down automatically because it thinks you're awake now, you have to set it again, when you go back to sleep. No big deal, but now you'll only see that last portion. You can't any prior part of the night, because history is blocked and can not be released. Get your add out of there! Or let us purchase the upgrade! This is BS. The app is worthless without it. ### 4/5 — Helps you fall asleep & wake up fresh *2015-02-11, version 1.1.1* With charts to see how your sleep went, this app is almost perfect. It loses a star for the odd design (and occasional chart hiccup) but otherwise love this app. I recommend it to everyone that ever needs to wake up earlier than whenever their body's own internal clock tells them it's time to rise! ### 5/5 — I luv it💞 *2014-09-12, version 1.0.20* This is the best alarm I have ever used, I instantly fell asleep with the soothing music. It has Beautiful sounds. Best of all it's loud enough to wake me up! I really luv this app!!!!💗💓💛💙💜 ### 4/5 — Cool app *2014-01-12* Really helps you fall asle... ### 5/5 — Awesome App! *2014-01-05* This is one of my all-time favorite apps. I don't know how it knows when I am awake or asleep, but it does! The gentle wake up from light sleep is so sweet, I wake up smiling. When I sleep deeply I can really feel the difference. Thank-you! ### 1/5 — Crap *2013-12-10* Worst sleeping app have to pay for all songs waste of time and money ### 5/5 — Great *2013-12-10* I really like it. It really helps me wake up and fall asleep.Great ### 3/5 — CheekyCoaster *2013-12-08* This app does what it says it's going to do with the exception of tracking sleep patterns of multiple days. I'm fine with the two song that sooth you too sleep and wake you up. It would be nice to have the option to download my own songs. Overall I found it useful. ## Frequently asked questions about Good Night's Sleep Alarm ### What does the Good Night's Sleep Alarm app do?
