Why does my iPhone 5c keep freezing when I go on snap chat

[iMore Question]

Every time I go onto snap chat my iPhone freezes and I have to turn my phone off by a little box on the screen because my power button doesn't work so I have to go wait for my battery to drain why does this happen?

Have you tried uninstalling and reinstalling the app?
