Pretty Good, but not perfect. I liked this application, it was the best reverse polish application i could find, and it's pretty good, but it could be improved. I like the fact that it has a basic mode and scientific mode and can can go back and forth easily. Ok, here are things that can be improved: First off, it's really sleazy how it asks you to rate it, and then only gives you a choice of love it, or has problems, and will only send you to google to rate it if you first say you love it. Come on! you dont have to resort to that. Th
For those who love RPN Great app! It doesn't matter which way your screen is oriented, the app accommodates it. I don't need graphing so this is fantastic for me (no fashion school bs). I'd still be using my HP-45 if HP had designed a more rugged display system.
Great RPN calculator RPN may seem awkward at first, but it works more like our minds, it's faster and more accurate than conventional calculators. Great app! I am disappointed that RPN is not taught. It's far superior than the traditional calculators.
Awesome app. Does almost everything my old HP 32SII does (except programmable functions). Yet it also does more - like letting you view the tape of your string of calculations and then share that via email, etc. Simple, reliable, just works. I can hardly believe that such a great app is not only free, it's also free of ads and doesn't harvest your personal data. Hats off to Mr. Falk for this selfless contribution to the world of number crunchers.
Brilliant This calculator is one of the best i've seen. One query though, can't work out how to use the 'frac' button. Cool, I should have worked that one out, tganks.
Great calculator It keeps getting better and better with each upgrade. I use it all the time.
Version 3.0 uses decimal arithmetic instead of binary for better compatibility with HP calculators, reduced round-off error and higher precision (18 decimal digits).
Version 3.2 improves the appearance of small screens. If your device doesn't have a small screen, you can ignore this update.
