Works great

Wish there was a 41 CV version to replace my real one. But this is a good replacement.

I'm glad you like Free42, but if you're specifically looking for an HP-41CV or CX emulator, i41CX is a good option.

RPN Rules

My physical HP calculator died after 36 years and like many old engineers (I suspect), I wouldn’t use anything else. I tutor high school kids, with their TI 83’s and 84’s. Even though they can text much faster than me, an RPN calculator runs circles around them.

This app is a perfect replica and I urge anyone who is allowed to use an iPhone to try it. It takes about 20 minutes to get used to a completely different way of operating, but you won’t ever go back to algebraic entry.

Very Nice

Works like it should!

Great tool & good fun to use.

Thank you
