Weird Android Calculator
60 points Medium

I've found this very weird android application.

Seems to be some kind of calculator, but there is something strange with it. Can you find out what it is?

Note: You don't really need an android device to solve this. But it might be helpful :)

Awesome challenge! I avoided this one for a while because it looked too difficult. Solved after a bit of research... Didn't use any fancy tools or anything on my end... Good balance of points and difficulty.
