I almost hesitate to weigh in since so many others have. The HP41 app is actually an emulator which runs the actual firmware from the original calculator. If you have HP41 programs you like and don't feel like porting them, this is the best going. However, I like "Free42" which is a complete but accurate rewrite of the HP42 calculator. It's available on windows and android. It also features 128 bit calculation, including the PI Constant. If you want an actual calculator that you can hold in your hand and (in some cases) is a pretty faithful reproduction of the HP calculator, I recommend checking out "Swissmicros.com". They have other RPN calculators there too. Oh the infrared on their products actually works with a real HP printer.
