Description
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.

3 ★ Good app... But it doesn't work for many other functions like Greatest Integer Function , modulus function , etc . Please add these functions also in next update..
5 ★ Best app for graphs in every way. Can even see complex number graphs. Thank you for this app.
5 ★ I dont normally write a review But this app is fascinating... I can plot as many functions as I want on same graph and I am not sure I have gotten to the endpoint of the values it can process... I urge people to install it Thanks to the developers! BRAVO!
5 ★ This app is just excellent! So many options for graphing and solving all kinds of equations and the graphics are excellent. Even has the ability to save a screenshot of the results. Top quality. 👌
4 ★ Good but some graphs like e^x and function in function cannot be drawn
5 ★ Nice app buddy.But it would be more helpful to me if it contained Greatest Integer Function (G.I.F.)[.] , and fractional part functions. I am waiting for these. Till then ☆☆☆☆☆................ Okay I got it. Thanks for the help friend. (That was a very quick response)😁👍👍👍👍
5 ★ Very awesome app for students to see the function properties.. Specially for entrance students who need the detailed and exact graph with there values... No other apps can do this. Thanks to the devolopers for helping the students from making this app..
5 ★ no intrusive ads! The interface is smooth AF and the theme is well-thought of, which is a great plus. Great App. Totally recommended!
3 ★ helpful, but please give some instructions of how to use it. Was finding it difficult to write absolute value function (turns out we have to add "abs" before the parentheses).
5 ★ very good app. you can use it easily and it is a good tool for visulizing function and implicit equations.
4 ★ Great app but I'm having trouble in getting the graph of inverse trigonometric functions. Would love to get some help on this.....
4 ★ It's really good, but it would be better if we could get ups and downs in different colours for 3D to get a better picture of the effect of equations.
2 ★ I can't get the graph of more than 1 function together in my phone. Like getting the graph of x^2, x^-2 and x.sin(1/x) together. when I press add it doesn't work.
5 ★ Very simple and easy to use, you can simply write the function expression ex: f(x)=exp(x) And you immedialtely get the curve, excellent.
5 ★ This is a great app. It really helped me a lot.
