Great RPN Calculator

I have always used RPN calculators and could not use the standard x+y=z calculator that comes with the iPhone.
Now I can use my iPhone for numbers again. Great product. Apple should have it as an option to their puny app.

Fairly good but neglected

This RPN calculator is fairly good but it's missing some important features such as STO and RCL. It could also really use a stay-on-top feature.

I've communicated these to the developer but he doesn't seem interested in doing anything.
