RPN 30 app for iPhone and iPad

Reverse Polish Notation ("RPN") is an alternative way to complete calculations. Many find it to be more intuitive and user-friendly than the "normal" way of using a calculator. RPN works entering numbers first and then the operator (i.e. 53 47 + will give you 53 + 47 = 100).

This is my artistic interpretation of the ideal form for a calculator, taking inspiration from the standard Apple iPhone calculator. Make sure to spend a few minutes to get the hang of the calculator and also read the short help guide (accessed by a long press on the help button) to get the most out of it.

No ads, no paid features, always free to use.

Please enjoy and leave a review if you like the calculator.
