I spent over $100 in 1988 for the original HP-42S and it was worth it! Now that I can spend $10 and get a more advanced version of the same thing on my phone is amazing. This is the best handheld calculator, in my opinion, ever! I've been using the Free42 version ever since it came out and now it is even better with the Plus42. The software by Thomas Okken is rock solid and well worth it!

I liked the Free42 app, then I got a Swiss Micros 42 and loved the display and added functionality but wished that I had it in my pocket when I needed it. The Plus42 app is perfect for my needs. It's hard to believe that a $10 purchase could make me this happy. The TVM solver has relegated Droid 48 to the least used app on my Pixel. Thanks for all the time and effort to make Plus42 a perfect extension to the wonderful Free42.

This app emulates and improves upon the features of the HP42 calculator and the HP-82240 printer. *Loading and saving of calculator states, programs and copy and paste data input *Solver for algebraic expressions *Units in calculations *TVM and statistical functions *Unlimited stack *User defined functions *Recursive programming *Lists and matrices and directory support *2D plotting =This is as close to a perfect calculator as you're likely to get.

My only physical calculator that I owned was the HP35. The Free42 and Plus42 are wonderful walls down memory lane. I have the Plus42 on my Xiaomi Redmi Note 9 Pro where it fills up the whole screen and it feels even more like the real thing. Use it for everything, mainly for projects and domestic maths.

I liked free42 but needed more than 2 lines, one of which was more often than not used for menu options. This app is better than I could have even hoped, with fully configurable lines up to 99, and adds built in unit conversions, directories, and several other RPL like niceties, while sticking with the simpler programming and functionality of the 42s model. Very happy so far with what is only version 1!

About this app

Plus42 is an advanced scientific programmable calculator, based on Free42. Free42, in turn, is a complete re-implementation of the HP-42S scientific programmable RPN calculator, which was made from 1988 until 1995 by Hewlett-Packard. Free42 is a complete rewrite and contains no HP code whatsoever.

Plus42 builds on Free42 and adds: Algebraic expressions modeled after those used on the HP-27S and HP-17B/19B; attached units and unit conversions modeled after those used on the HP-48/49/50 series; directories for more organized storage of programs and variables; a larger display, with 8 rows and 22 columns (131x64 pixels) by default, which the user may resize at will; time value of money and amortization schedules; and two-dimensional plotting of functions, with ability to zoom and pan, and find integrals and roots from points in the plot.

New features

Fixed ALPHA pasting during command entry.

Fixed MODES and DISP menus in EQN list view.
