Description
Grapher is a fast and 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, polar coordinates, 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 by their name.
As I strive to make Grapher fit your needs, any feedback and bug-reports are greatly appreciated. This free version has most but not all features; please consider buying Grapher Pro to enjoy awesome extensions such as parameter sliders and complex plotting!
Curve types • Function (e.g. parabola, sine wave) • Polar (e.g. rose, spiral) • Parametric (e.g. ellipse, Lissajous) on the xy-plane or rθ-plane • Implicit equation (e.g. conic sections) • Implicit inequality (e.g. half-plane) • 3D function (e.g. paraboloid) • 3D parametric curve (e.g. helix) • 3D parametric surface (e.g. sphere, hyperboloid)
More features • Equation solver (numerical) • Find roots, extrema and intersections with other functions • Functions can reference each other, e.g. g(x)=2*f(x+1) • Custom math keyboard • Auto-detect input type • User variable support for both numbers and functions • Adjustable parameter range (for cartesian, polar & parametric curves) • Input history • Plot up to 28 graphs at once • Differentiation (numerical) • Trace graph • Capture screenshots
Note: Mathematical functions should be typed by their names, for example sqrt(x) means √x. Hold a key to see all function names starting with that letter. If something is unclear, be sure to check out the 'Help' page as all details are summarized there.
Recent changes: • Removed ads: I decided to make Grapher ad-free in order to facilitate your remote learning experience with minimal disruptions. I am wishing the best of luck to all students who are working through these difficult times! • Added absolute value '|' key • Custom keyboard bugfix

Comments on Grapher - Equation Plotter for Android
★★★★☆Ashley D.· Mar 15, 2021
This app is really cool! I was going to use it to graph equations for my algebra 1 homework, but it's a little beyond me. Not my thing, but I bet lots of other people can enjoy it
★★★★☆Lateef Olayinka· Feb 28, 2021
I love it. It is good at drawing any 2D and 3D graphs, but I find it difficult to draw the graph of implicit functions F(x, y,z)=0 where it is only programmed as Z=f(x, y). We will be glad if you can fix this
★★★★★Suraj Kumar· Jul 8, 2022
This app help me to see the beauty of math with very smooth curve
★★☆☆☆Black Devil· Sep 17, 2021
I can't put root and cube root functions because there's no root or cube root sign. I want their graph
★☆☆☆☆Sahaj Self Study· Feb 8, 2022
Wasted time, no use to call it 3d plotter
★★☆☆☆gopal rebari· Nov 9, 2020
Also show the limiting value at point where function becomes indeterminate form.
