Best calculator

I bought several calculator apps to try out and this was the only one that was adequate. It has a simple prompt you type expressions into and it can do both symbolic and floating point math. It can give back back real numbers as well as expressions. One complaint, I wish it was easier to type in functions instead of picking them out of a list. I would pay for the app again if the author were to make another version that took advantage of bigger screens.
