This has been my go to calculator and I find it is the best emulation of the 41CV/CX family. It goes beyond that in many ways from memory to the expanded capabilities. It has always responsive, and has never crashed. Real HP 41 CV an CXs got me through college. Yes that was a long time ago. The access to modules has allowed me to use some of the extended features that made the original so powerful. I was very much into synthetic and Forth programming on the original calculators. I still use some of the programs I wrote in college on this calculator. I wish there was a macOS version of this app.

I cannot rave enough about the i41CX+ 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.
