Software Features and Description

1. In addition to being functionally equivalent to the world-renowned HP-41CX and providing access to its entire library of modules and programs, i41CX+ is enhanced with iOS and hardware features, keyboard overlays, rich set of import and export capabilities, traditional and upbeat diverse set of skins, complete color control, iCloud support, and much more.

2. i41CX+ is an advanced programmable and expandable RPN scientific calculator with a virtual thermal printer/plotter and workstation-class CAS capabilities that is far beyond a mere replica of the original.

3. Moreover, the CAS has full access to the calculator registers so it is possible to combine RPN programs with CAS programs.

4. It's like having Mathematica or the computational engine of Wolfram Alpha in your pocket and, best of all, it runs natively so no internet connection is required.

5. A comprehensive FAQ and Mini-Manual are available at Please don't hesitate to use the "Contact Us" link there if you cannot find the answers or information that you seek.

6. • Import/export data, programs, overlays, modules, etc.

7. The CAS is fully programmable and provides the ability to reuse previous results in computations.

8. The i41CX+ CAS is a full implementation of REDUCE.

9. This is the finest and most powerful scientific/engineering/financial calculator for iOS devices bar none.

10. Thank you.

I cannot rave enough about the this app+ app. I have a real hp41CV from college and grad school days (mint condition). I use it rarely so that it doesn't wear out. First HP I owned was a model 67 and I was hooked. This 41cx app keeps the entire 41 product and accessories, and then some, in my pocket. Couldn't be more happy with the performance and user experience. Well done !! Please keep it going. It's bad enough HP has abandon these gems. I'd like to know that this app will remain for years to come. Thanks for the great work.
A Flawless Emulation of the Classic RPN Calculator

By GB of NJ (Pcmac user)

The emulation works perfectly. Bells and whistles are available but don’t interfere with the functionality. I haven’t tried any of the bells and whistles so I can’t speak to their utility. But I am happy to testify that the full functionality of my beloved old Hewlett-Packard calculator now runs flawlessly on my iPods and iPads. No doubt it works on an iPhone also, but I don’t use an iPhone. Thank you to the developer for this gem.
Amazing. Clearly a labor of love.

By lhymes (Pcmac user)

Really happy he continues to develop this calculator app. It's pretty much the most feature-rich option you'll find and the updates continue after so many years. Very few apps see as much development over the years as this one and it deserves your purchase if you're on the fence. So happy it continues to be developed.
Could be great with three improvements...

By markingolden (Pcmac user)

This is an xcellent reproduction of the original HP41CX+ which was arguably the most useful scientific calculator in history, but I have three gripes: 1) The nearly 4 seconds it takes to load. 2) The scaled down button size required to fit the iPhone screen. I find myself constantly checking to make sure the key I pressed actually registered correctly with the program. 3) The original calculator has a crisp click feel when you touch the key. Since this is a simulation, that is not possible however haptic feedback may be a solution to this problem. All that being said my comfort factor with the original keeps me using this app as my go-to calculator. Please address the above for a five star rating.
