One of the best HP 'emulations', nice support, great application, I use it as one of my day by day calcs
This app is a very good emulation of my HP42S. I do wish the display could be expanded to show 4 or 5 lines at a time and that it had a white background instead of grey.
AAA+++ best calculator app ever. Thanks Thomas.
Just like my real 42S from 1989, though I miss the tactile keys, the display is clearer in the app. Once you learn RPN you never go back, and stare in wonder at basic calculators.
Thank-you. App faithfully replaced my real HP42s and kept my RPN mind happy.
This program rocks.
MATA, MATB, and MATX should exhibit the same stack lift behavior as EDIT and EDITN, but didn't. Fixed.
Excellent scientific calculator with expressions, fractions, repeating decimals.
This application supports the calculation for simple and complex formulas.
