A comprehensive scientific calculator app

Yes, your droid comes with a calculator and you might even already have an additional calculator app. However, if you are surviving high school or are in any scientific degree in college, those toy calculators aren't enough. You need to solve quadratic equations and polynomials and vectors and matrixes and draw graphs and all that odd Math stuff we mere mortals can't understand. Perhaps you need to save it all and bring it with you to your PC.

Graphing Calculator is an insanely complete app, thought for helping any need any algebra student may need. It also comes with a smooth interface and a supporting website and email address.

This pro version comes free of ads and can be run offline.

Developer's original description available here
Graphing calculator with algebra. Essential tool for school and college. Replaces bulky and expensive handheld graphing calculators.

Multiple functions on a graph, polar graphs, graphing of implicit functions and parametric equations, inequalities. Displays function values and slopes, roots, extremes, intersections. Algebra, polynomials, polynomial equation solving, matrix and vector operations, fractions, derivatives, complex numbers and more. Shows results as you type. Use navigation menu to switch between modes.

    A damn calculator costs over 10 times this price, and the free version worked offline, keep up the great work. PS: fraction answer option would be nice, along with standard engineering constants. I see another user suggesting this and I saw your reply, but waiting for implementation.... Again brilliant app

    This app is approaching the capabilities of a graphing calculator costing over $100.

    I like it. It does everything I want. The only problem is sometimes it can take me several minutes to figure out how to do things.

    Wish there was a mode where it wasn't quite so good, as it makes you a bit too lazy and you can trial and error your way to certain solutions too easily when you should know the proper methodology instead.
