I use HP (because i want RPN), and i use this: https://play.google.com/store/apps/details?id=org.ab.x48 https://play.google.com/store/apps/details?id=org.ab.x48 This one is better for newer models: https://play.google.com/store/apps/details?id=org.emulator.forty.eight https://play.google.com/store/apps/details?id=org.emulator.f... Yes,i know it's an emulator, but for the same price as a calculator, i get an emulated calculator + a bunch of other stuff, including wolfram alpha, huge database of knowledge online (wikipedia) + of course a phone. ...and on the other hand, i have this always in my pocket.
