Free version also available.

2D: Functions, Parametric Relations, Polar graphs
-Algebra: Zero, Max/Min, Intersect
-Calculus: Derivatives, Tangent lines, Integrals

3D: Functions, Parametric Surfaces
-Lighting, augmented reality mode

-Touch panning/scrolling
-Tracing w/Derivative

Scientific Calculator:
-Live calculation: evaluate expressions as you type
-Complex (imaginary) numbers (a+bi or polar)
-Probability distribution functions (PDF)
-Numerical derivative/integral

    Quick question: how do you input the z value for the 3d graph?

    App I've downloaded so far! Keep up the good work. And like others said, labels for axis please.

    Overall the greatest Android graphing calculator. However, axis labels! We need them!

    Awesome support
    Motorola Xoom. The developers for this app are great. This app was force closing on me everytime I would zoom in or move a 3 dimensional graph consisting of 2 or more functions. I emailed them my problem and a day later they got back to me
