Bugging and crash?!

March 7th I download this app for my high school classes and the app crashes on me. I rebooted my phone and opened up the app again where it froze for a full twenty minutes before I had to reboot it again. Again, I opened the app and immediately it crashes and directs me to my home screen. I try once more and I was actually able to attempt to login but it froze AGAIN! One last time, rebooted phone, opened app, crash! Im using this on an IPhone 5 that has not been altered whatsoever so whats the deal? Someone better fix this quick because starting today its become MANDATORY for my biology class.
