Crunch - Calculator Redesigned

Technology has continued to evolve. Why does the calculator still look the same?
Crunch is a calculator designed to take full advantage of your mobile device, doing away with the look and feel of the traditional calculator. It's intended to feel like a digital whiteboard, combining the visual aesthetic of a whiteboard with quick and easy digital editing.
In addition to basic scientific calculator functionality, Crunch also gives you the ability to:
* Easily switch between calculations and edit previous calculations
* View answers as fractions or decimals
* Drag and drop live answers to use them in other calculations
* Create variables and assign values to them
* Store functions you use frequently and drop them onto the canvas when you need them
