I love this app. Ive been using it since July of last year (2015) every day and Ive stuck to it ever since. It has such a cute icon (I LOVE THE CLOCK!!) and a very nice design, and is very convenient to use for logging sleep. Also, having the option to use my own music for the alarm and being able to go to sleep after pressing just one button is very helpful.
One thing: currently when I press the "Graphs" button from the trends page, the app always crashes. Before, one of the best things I liked about this app was that I could see my sleep patterns over any period of time. However this doesnt work anymore - please fix it!!!
Correction: I deleted the app and reinstalled it, and now the graph option works!! Yay!
