"But i wonder, how do you make such an app? "
This is a really open ended question.

Do you mean who do you make an iPhone App?

If you mean how to code an emulator, there are three ways. You can build up the interface and hand code all the functions using the underlying math functions as they are. It looks OK, but not very accurate.

You can use the underlying math functions and jigger the output to match the target. More fidelity, but you need extensive knowledge of the target.

You use the original ROMS from the calculator to perform the functions, easier than re-jiggering the native code and the best fidelity, bugs and all.
