RPNcalculator Reviews

I love the RPN calculator. Only problem is that it takes very long to load first time on Windows 10. Wish there was a way to make it load faster and pop up sooner.

Very nice functionality; it is now my main Windows calculator. I find it it's design somewhat too bulky and colors are not ideal, but this is of course minor points. Overall, very good work; probably best RPN calculator currently available for Windows.

Good looking RPN calculator, but it comes up with inaccurate numbers some times (for example, 18.7-11.9-6.2=0.599999999999999 instead of 0.6). Emails to developer bounce, so it may be abandonware at this point..

This is excellent. No need to look for anything else except version 2.0.1. ;-) Comments: 1. Indicators for number system and angular units not working for me on Win7. 2. Symbol on multiply key is identical to x on variable "x" key. (Suggest "*" or ".") 3. Minus sign on subtract button is a hyphen. Needs to be wider. Thank you.

clean design + functional = nice (lol, not rpn). my new go-to calculator for windows. EDIT: also do agree with cursor at start of number issue (minor though)

nice look but : 1-menu does not work 2- where is equal(=) button (enter?)
