Calculus Course Assistant

First off, this app is just a "skin" that sends your queries to the Wolfram Alpha servers. So if you lose internet access, this app won't work at all. Second, it's not very flexible in terms of inputs. The onscreen keyboard might be okay if you have a touchscreen, but this sucks if you want to use a traditional keyboard. To type in "sin(x)" you must click the "sin" button on the screen, because it will not let you type the letters in individually (can't have an "s" since that is not one of the allowed variables). While this app is at least flexible enough to allow a few common variables other than "x" (like "r", "t", and theta), the input is so frustrating that a student will spend too much time learning the quirks of the app and less time learning. As a Mathematica user, I am very disappointed in this app. Give us a "Mathematica-lite" engine so it will run offline and allow full keyboard input.

There is a learning curve, but it's not that difficult to use. Of course it requires internet because it uses the Wolfram Alpha engine.

I keep getting the message: Wolfram Calculus Asst does not understand your input. But no other info is asked for, only $2.99, but not worth it.

The programming is genius, almost every calculus principle is covered in depth, detailed steps are given on how the problems are solved. Definitely worth the money if you are in any level of calculus, even if you are just needing to quickly verify an answer to a problem.
