Description
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.
What’s New
Version v1.1.16

Ratings and Reviews
Fantastic app
This is a beautifully crafted, powerful app and anyone interested in calculators should have this in their collection. I have recently bought both the SwissMicros DM41X and DM42, so to have the iOS Plus42 available on my phone/iPad when out and about is incredible and very handy. It joins the faithful recreations of the HP50g, TI59, TI84, HP15C, FX602P, i41CX etc on iOS. 😎👍
I would also like to take this opportunity to thank the author for making the free, open source Free42 app available too. I have the Free42 AND Plus42 apps running on the Linux desktop. Fantastic!
Fantastic
I have a real HP 42S and this is a great choice for an iPhone calculator. It does everything the 42S does and more. I like the different screen displays and the haptic feedback. My favourite iPhone calculator so far!
