Calculator RPN App Reviews

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.

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.

Don't care about past evaluations, now he is perfect. A perfect calculator.

This app has a clean feel and nice presentation, but is seriously lacking in the calculation department. It seems to calculate with 32 bit integers and doesn't have any overflow protection, making any sort of scientific calculation next to impossible. If you're looking for a clean RPN, you should look elsewhere.

Functions properly as an RPN calculator that puts an expression under the x register which summarizes the operations. Nice touch but that's pretty much where it ends. On computer screen the calculator opens with ridiculously wide buttons in a window that takes up a third of the screen. Sure it can be resized but next time it opens at maximum size again. Setting includes option to specify number of decimal places from 15 to 4. It would be nice if this could be set to 2 for financial calcul
