Nafoni: another math application that allows you to solve equations, simplify expressions, plot functions on a grid and much more. The application looks very good, but is perhaps more limited in terms of functionality than WolframAlpha. It does, however, look very well and manages to do all of it offline, as opposed to WolframAlpha.
MathStep is a symbolic pocket calculator with a complete CAS (Computer Algebra System) built-in. That means that it can solve math problems for you! It has an expression editor with a live preview and even gives you hints to solving a problem by yourself for some operations. It can even work without an internet connection!
The following operations are currently supported:
- Calculating limits
- Calculating sums
