I won my 42S in a tech quiz and treasured it for more than a decade until the LCD went black. I was crushed. And then I found this wonderful app. Even if it can't replicate the joyous feel of those wonderful hard keys, it's surely the next best thing. I've downloaded and printed out the free manual too, since I seem to have misplaced the original. I'm a happy camper!
Absolutely wonderful--exactly what I needed. Now I have easy access to my favorite RPN calculator wherever I go. I love the audio click keypress feedback, and being able to switch between portrait and landscape calculator keyboard layouts by rotating my tablet. Thank you so much for developing this app.
Better than the original HP 42S. The ability to import programs much easier than re-entering code.Familiar RPN preserved. Fantastic. Reloaded app onto new Huawei P9.
Fantastic implementation of the 42S. Indispensable app for every RPN enthusiast! 5/5 for a very professional product. Great work Thomas.
Fab fab fab the best HP ever now on my phone and tablet
Best calculator app I've tried.
Fixed bugs in DIM, SIZE, SIMQ, CLV, STO, and STO*: they now all return "Restricted Operation" when the target is being edited by EDITN, and they set IJ to (1, 1) when the target is the indexed matrix.
CLALL didn't always exit all menus. Fixed.
Excellent scientific calculator with expressions, fractions, repeating decimals.
