42s is an iPhone port of Thomas Okken's excellent and stable Free42, a complete re-implementation of the highly praised HP-42S RPN calculator. There are no ROMs or emulators involved allowing 42s to run natively and fast. This calculator provides all the functionality of the original 42S with several hundred functions, programability, printer output, etc. Additionally, several enhancements have been made over the original calculator such as additional precision and the ability to import and export programs.
Features include:
* Programmable for custom functionality. Packages are available for additional functionality including Engineering, Scientific, Financial, Statistical, etc. Backward compatible with 41CX programs.
* Internally stores values and performs operations in 25 digit decimal precision.
* Use the iPhone keyboard for entering character data, or variable names.
* Runs several orders of magnitude faster then the original calculator, including program execution, solving, integration, matrix operations, etc...
* Swipe LCD vertically to get up to 7 lines of display.
* Double tap LCD to cut and paste one or more numbers from the stack, or paste one or more numbers to the stack
* swipe LCD vertically on the right hand side to roll stack contents, or to scroll a program in program mode.
* Sound tones mimic those of the original HP-42S
* Double tap print output view to copy print contents
* Display last x register in the upper right hand corner of LCD
* Tap LCD in alpha entry mode to toggle the display of the iPhone keyboard.
* Added option for a dynamically sized stack. Choose between the traditional (X, Y, Z, T) style stack, or a fully dynamic stack.
* Added option for no stack lift on Enter.
* Added DROP command, executed by doube tapping the back key
* Added option to remove device status bar for a larger LCD
Added additional lines to LCD modes, now supports up to 6 lines of stack, or 7 lines of program.
* Added scroll bar to program mode.
* Program mode can now be scrolled with the menu active.
* Import/Export functions.
Added in 3.0:
* Compatibility with iOS4 including application switching and compatibility bugs
* Added hi-rez (retinal) key pad image for iPhone 4
* Added Undo and Redo functions for the stack. Swiping the LCD left or right performs these operations.
* Added display option to show flags 0-4 at the top of the display if they are set.

‘State File Corrupt’ Error

Kemo Sabe on

Byron, Love the app! The recent 15.4.1 iOS somehow spit out an error that doesn’t fold the settings like dispensation and mode when opening and reclining the app. I use your all nearly every day. Please help! Thanks so much. Tried reporting via AppStore button and didn’t have any luck reaching you. Cheers!!!

All Time Best HP app

This is by far and away the best implementation of a Hewlett-Packard calculator available on the App Store. Hard stop. I would echo the sentiments of other reviews, that the developer please update and maintain this app. If you charged $50, I would pay it… UPDATE 9/2021: Still an amazing App that I use daily. No updates in 4 years has me worried. Please don’t drop support. With larger phones, one amazing enhancement would be to add an option for an 8th row, which would be user selected (like Prob) or else user configurable. In either case the extra row would stay in place, not dropping down and cutting off current top row. It would stays in place until the user switched it. Seriously, Byron, I would pay you $1,000 for the 8th row. There is also room for a 9th row. 😀

By far the best scientific calculator

I just wanted to update my review. Conclusion: I still love this thing. I own two real 42S calculators, and the one from Switzerland (DM42), but this is the best because I always have my phone handy, and the extensions to the original are well thought out. I love this thing. I collect calculating machines of various kinds - from Sorobans and Napier’s Bones to slide rules and mechanical calculators to electronic calculators, and this is my favorite on my phone. And the only one that merits a top level spot on the first page of apps.

Used to be GREAT!

This app used to be great but one of the last updates lost one row of keys above the enter key. What happened to the STO, RCL, SIN, COS and TAN????

Opens then disappears

Fantastic app! I’ve been using it almost daily for years with programs I’ve written. Can’t work without it. Now with the iOS 14.2 update it will open and then immediately disappears Hopefully this program is still supported

Crashes on 14.2

At work I can either grab the real one or grab my phone. The 42 on the phone is way easier to read now that my eyes have grown tired lol. Best app on my iPhone hands down.

I really liked this but I found the integration function is not accurate when integrating the normal curve function. Off by 9%. My 15C is slower but right on accurate.
