Math DragOn

An intuitive calculator that can perform symbolic calculations.

About Math DragOn

Math DragOn is an application that combines the ease of a portable calculator with the power of a smartphone. The app features a  very intuitive way of entering calculations with drag-and-drop using the touch screen of the smartphone. The calculations can not only be approximated, like a regular calculator would do, they can also be evaluated symbolically. For example: calculating the derivative of x2 will give a nice 2x as result.
