It replaces my HP 15 scientific and my TI BA II financial, smoothly toggling between sci and fin modes without losing my data. Can't say enough good stuff about this app. If you don't already use RPN, its well worth the 10 minutes to learn, you'll never go back to algebraic inputting. ### 5/5 — well executed *2010-08-11* good use of color and sound. feels solid. not fancy, but good rpn financial and scientific calculator. compare with p42. only 1 line of stack displayed means buttons are large enough to use. great work. note to dev: check out np1 calc. it has an interesting model for programability. (but is poorly executed) i'd be interested in your take on a programmable calculator. ## Frequently asked questions about Figures Financial RPN Calc ### What modes does Figures Financial RPN Calc support?
