iOS7 Calculator

Be sure to see 2x and ACTUAL PIXEL SIZE RIGHT HERE :)

Hello all... when I first saw the calculator app in ios7, I instantly thought how cool would it be if it looked similar to the phone keypad app. I put this together to give you my idea of the calculator iOS7 redesigned :)

I also added a undo/redo option... never seen that on a calculator and with my clumsy fingers, I always tend to mess up.

Thanks you @pixeden for the awesome 5s template!
