This beautiful calculator App is crafted for people extensively utilizing calculators. It focuses on usability and fast execution of calculation while heavily utilising gestures.

This App is following solely the post-fix notation where the operator follow after the operands instead if being in the middle (in-fix). In post-fix notation (another name is RPN for Reverse Polish Notation), the operator follows its operands. RPN is heavily used and loved by scientiests, mathematicians and computer specialists. The beauty of RPN lies in faster calculations compared with our usual infix notation where the operator is in the middle of two operands. RPN doesnt need expressions to be parenthesized and fewer operations need to be entered to perform typical calculations.

Getting familiar with this will take a moment, but afterwards you will be amazed how easy and fast you will execute your calcuations. You wont need any parenthesis even for the most complex calculations. It is evident that RPN users do fewer mistakes. To avoid confusion and errors especially when conducting the first steps, this App shows the executed calculation in the very familiar in-fix notation.
