Wonderful Tool – RLM-Fin-PL Review
Faithful simulation of the HP-12C with a bunch of useful extra features. This is one of the first apps I bought for my iPhone 4 and it has worked flawlessly from day one. I use it all the time. Five stars from top to bottom. If you like RPN and especially if you like the 12C, get this. You won't be sorry.
PS: Mac version is excellent too.
