a41cv

a41cv is my open source simulator of the legendary HP41CV RPN calculator. The first production version of a41cv was released in February 2011. Nearly all of the original HP41CV functions are implemented.The calculator differs from the HP41CV in the following ways:No definition of number of registerProgrammes cannot be assigned to keys (working on that)Not all special flags implementedNumber of programme lines only limited by phone memoryOnly a simple programme editor (by now) but full import / export of programmes on cvs formatStill trying to make a41CV fit better on the now more than 1782 different devices it works on according to Google Market

Had hoped this would be good asI love the hp41cx. But the first test I did failed. Hit "shift" "FIX" "3". The result should be floting point display rounded with fixed 3 decimals of accuracy. Does not work. Pity.

I love it. But for some reason the main screen doesn't show any numbers now. Can see them in the stack but they're a bit small. Any chance of an update???

Absolutely stunning. Works perfectly as a RPN scientific calculator if you don't need any programming features.

For the SHIFT -- FIX function to work....use 2 digits instead of one like on the calculator.....put a zero (0) in front of your desired entry......for 4 digits after the decimal point.....enter...04

Used a 15C in college 30 years ago and got accustomed to rpn entry. Can't reliably work a "normal" calculator to this day! Great product.

Why does a calculator need access to media, photos and file?

P-R function gives incorrect result as Y register is always positive. (regardless of input)

Great app, I use it often at work and sometimes at home.

Couldn't figure out how to program it. It doesn't work like original hp41

Bad. Waste of time.

Ste. B. Jul 8, 2015     

I have had a HP41CV during school time and missed it. I use this one almost daily.

I loved this app and the features presented, but the latest updated screwed the screen presentation on my nexus 7. So uninstall we go. Will likely reinstall once the screen issue is corrected.

This really is the closest to the real thing. I use it all the time at work. No need to carry a scientific calculator around for with me any longer. Give it a try.

Wore out a 41C and a 41CV in 25 years. This app is way better than HP's current calculators.

Jan. H. Sep 25, 2013     

To good to be true. Same as my old but as new original HP41CV. Only missing the triangular calculation programs as SAS.

Joh. W. Nov 15, 2015     

The display might be alright for a phone but on a tablet, the keys scale but not the fonts on the keys on on the faceplate. In landscape mode, the unused portion is distracting. The emulation should include various module packs as who would use a HP41CV without the math pack and thermal pack. The faceplates on a 41C series were replaceable so the various optional faceplates as well as those with the module packs should also be emulated. As this is an open source product, there's a chance it may get better

This app is a very high-quality simulator of a classic HP scientific calculator. Large screens highly recommended for use.

too small on my screen. would love to have it on full screen... there are some mm left. Even when resizing buttons.
