I still have two HP42s, one for my office at work, one for my office at home, both in a drawer. Free42 now resides on my phone and computers. It is a perfect emulation with some significant advantages in stack height and memory. I occasionally miss the HP's programmability, but usually just turn to a spread sheet for highly repetitive calculations or more specialized apps or programs for more challenging work.

Free42 is programmable too!

For a calculator app that optimizes keystrokes, this is the one. For the classic HP calculator experience in an app, start here. If you want an RPN calculator, you won't find a consistent, faster, smaller, scientific, featured calculator cheaper. If you want graphing or algebraic or textbook entry, keep looking.

I still have an actual 42 and this is a really good facsimile. It's actually better than the real one in that it has better precision (can work with bigger and smaller numbers). If you can handle RPN,the time. a great app. I use it all the time.
