No frills "No frills" might sound like a criticism, but it's not. If all you want is a simple, easy to use RPN calculator with basic features and an uncluttered interface then this is the app for you. I love it.

Good work The square root button is not needed (it's just a matter of using 1/x and x^n)...you could replace with "%" which is really the only missing function! Please set the color to be theme independent or give us an option to choose. Great app! Thanks!

Good at being a simple RPN calculator but ... could you add 'DUP' to copy the top most stack? I know I can use copy and paste yet I think DUP is faster. Anyway, great app :-)
