Grapher Pro is an effective equation plotter, capable of drawing any function (including complex-valued ones), solving equations and calculating expressions.

Especially if you’re a student, teacher or engineer, this app is made with you in mind! A wide range of predefined functions is available, including trigonometric & hyperbolic functions, differentiation and more. Anything you type will be processed and displayed instantly by a powerful math engine, in both 2D and 3D modes. Furthermore, functions can reference each other and will respond to any variable update.

Grapher is continuously under development, with more features yet to come. Any feedback and bug-reports are greatly appreciated!
