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!
