A great addition to my LG G3. I love that the original HP 42S look is an available skin, the only one I use. Print function integration is a major plus. I reported two very minor bugs to the author, both fixed perfectly in a couple of weeks. I never owned a real 42S, but have owned the real 45, 55, 25, 67, 97 and 41C. Love the 42S functionality. Congratulations, Thomas, and keep up the good work!
Best RPN calculator and HP emulator app that I know. I use it almost daily!
Realistic copy of my beloved calculator. Only critique is the ugly icon.
Works like my real 42!!
Excellent! I've been using an HP32S2 for years and love RPN.
Very good RPN calculator. Thank you to the developer.
Added "Always Paint Entire Display" option. This prevents display glitches with certain combinations of devices and skins.
Excellent scientific calculator with expressions, fractions, repeating decimals.
