    Description
    Arity is an Android calculator with some insane capabilities. It's capable of both 2D and 3D graphing and can even graph things like derivatives and trig functions. Unfortunately graphing is pretty much all it's good for, but it does it extremely well.


    Pros
    • Elegant 3D Graphing
    • Can graph multiple 2D function on a single graph
    • Can graph the derivatives for 2D functions
    • Can take screenshots of the graphs
    • Excellent performance even on lower end devices

    Cons
    • Cannot graph multiple 3D functions at once
    • No Multi-touch zooming
    • Graphs do not Auto-Fit
    • Advanced features have a steep learning curve
    • Does not evaluate non-numerical functions

    Glitches/Bugs
    • Input panel sometimes gets off-centered
    • Mini-graph sometimes displays improperly

    Wow! This app is a lot of fun. Thanks for another awesome review.

    How did you know the equation to make that graph? Is it on the internet somewhere? It's really cool.

    Actually I just came up with the equation while I was doing the review. Basically I knew I could use x^2+y^2 as a radial distance from the origin, and use the cosine function to create a radial wave based on that. The division part was just to cause the amplitude to weaken as it got further from the origin.
