Used to work, now is worthless

The app used to work fine and I used it all the time. Now its useless. Anytime I try to change the time of the alarm, the screen blacks out and when it doesnt, I still cant change the time. Its incredibly frustrating. If Im lucky, it only takes 10 minutes to update the alarm. Screw this worthless crap. They need to fix it.
