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.
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.
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.
Great calculator It keeps getting better and better with each upgrade. I use it all the time.
My go to box of brains. Awesome calculator. Use it daily in my job .... mine surveyor. Hasn't let me down once.
Very nice. The % operation works even better than on the original HP calculators.
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.
