i41CX+

Exceptionally true to life. It really has it all. Fully programmable, utterly useful. CCD module, PPC, it's all there. If you're looking for an RPN-style calculator that can do the lot, this app is worth checking out.

I OWN an original HP41CV since 1985 or so. It still Works.
Once you are loose on RPN (and wants to stick to it) it’s nice to have a CX+ on your iPhone and iPad.

As one of the early adapters, late 70s, early 80s, I still have a soft spot for this wonderful calculator.
This app is a MUST HAVE if you want to have a perfect taste of how the HP 41C(V/X) was, in those days.
Many thanks to the maker for keeping this app up to date.
Five stars, well deserved.

I've been using this app for a few years now and love it. I USED to be a user of the original which brought me to use this app, and I don;t regret it at all.

I really has it all. From standard use, writing programs, all the way to synthetic programming (those were the days!). CCD module, PPC, it's all there. If you're looking for an HP-style calculator that can do the lot, this is it. Just fantastic! Thanks AL!

I am very happy with this app on the iPad. I still miss it on my Nokia 920 windows phone 8.
It is nice to see that the synthetic programming still works and the PPC ROM can also be added.
Keep up the good work

Very nice calculator and famous too! For most supplied progs documentation would be very welcome. Will cost a bit but I think an app with documentation may cost a few bucks.

The HP-41 is of course still the greatest calculator ever, this iPhone version gives _exactly_ the same sensations (exhilarating!)

The HP 41 was designed by HP with much care and even after so many years it is still my favorite programmable scientific calculator by far. It is great to have an HP 41 with me in my iPhone. Beautifully made to really closely resemble the original one. The printer is very useful. It is now even extended with functions to use the build in GPS of the iPhone to make it even more powerful than the original one. It's a great pleasure to use this application!

Thuis had ik er nog altijd een werkend op mijn bureau maar ik miste hem flink op het werk, zeker na het overlijden van de HP27 (ook mooi en nog handiger, maar wat slecht gemaakt!).
Affijn, nu mijn lievelings rekenmachine altijd overal bij me!
Heerlijk dat al mijn "tik-reflexen" gewoon nog kloppen alsof het niets is.
Overigens ook dank aan HP zelf voor vrijgeven van alle documentatie en blijkbaar ook het niet klagen over gebruik van beelden.

Grafisch misschien niet de mooiste, maar met afstand verreweg de beste tot nu toe! (bv hier hapert geen toets)

This implementation of the HP 41CX calculator is the most complete, amazing application I have seen yet on my iPod Touch. Complete with a printer with the right sounds, a host of loadable modules, this is a joy for all fans of this great old calculator. If you have used the real calculator earlier in you life, this application will be like home to you. Brilliant. Besides, it *still* is a good calculator, so even if you are not a fan, but looking for a good scientific calculator, this is a great choice, and extremely reasonably priced.
