Grapher is an effective equation plotter, capable of drawing any function, 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.

Grapher is continuously under development, with more features yet to come. Any feedback and bug-reports are greatly appreciated. This free version is ad-supported, please consider buying Grapher Pro to remove all ads and enjoy extra features!
