This is a great app! – ND0 RPN Graphing Calculator Review

This is a powerful and well written program. Don't mind the freak who gave a one-star. He will fail his calculus course. I have a high standard on the calculators I use. Before this program, the only two calculators I feel like using is the calc-mode in emacs and the i41cx emulator in iPhone (which is so freaking expansive!). I have not used much features in this calculator but I see it as a strong competitor to those two. Thank the author for this awesome program and making it free!
