Description

A simple RPN calculator!

A simple reverse polish notation calculator loosely based on my trusty HP-32SII that runs on iPhone, iPad, and Apple Watch!

If you are familiar with HP RPN calculators, the operation of this calculator should seem very straightforward - albeit simplified. It can't be programmed, and it doesn't handle binary, or hexadecimal numbers.

But, it has a clean, simple interface with large, easy to press buttons. It has all of the functions required for quick calculations when your iPhone is handier than your computer or calculator.

And, remember those cool calculator watches from the 1980s? Unfortunately, none of them were RPN. RPN Calc brings a reverse polish notation watch calculator to the Apple Watch!

In addition to the standard RPN Calculator app that runs on iPhone, iPad, and Apple Watch, RPN Calc includes a handy micro RPN Calc Today Extension available for convenient access to quick calculations from the pull down Today screen.

What’s New

Version 13.0.2

- Interface refreshed and updated with a clean, modern design!

Incomplete - Please finish it!

Good to see there is now a 4 level stack, but still needs a roll buttton and most importantly an xy swap key - useless without it!!
There is also a bug with the pi key - it replaces the x register - needs to push x into y before entering the constant.

bit buggy

Seems to be no way to contact the author on his website so will do it here. Appears to have at least one serious bug. The FIX or SCI notation does not stick. I calculate $$ amounts but if I set it to FIX 2 and then do some multiplication it reverts back to SCI format - very not useful when calculating dollars and cents. Hopefully this bug will be fixed soon.

Basic RPN - needs work

Easy to use, visually OK. Only has a two register stack. Problems with sticking in SCI notation. No click sounds. No memory.

I prefer the built in SCI calculator as an interface - better look/feel/function - if only it was RPN.
