Perfect app!

This app is great! I wanted an RPN calculator that looked nice, and was free, and this was it! Has all the needed functions, a nice long stack, and is elegant and utilitarian. Perfect. I would have loved a way to paste in numbers, but I might just be missing how you're supposed to do that. And maybe a few more esoteric functions for fun, but over all this is the only good RPN calculator I've ever found for iOS.

Simple but great

This is the best of the free rpn calculators I have found. I actually like the while minimal gui. Plus is has all the trig, log, and power functions you really need. Great app!
Thank you for providing a fully functional rpn calculator for free!
