About Grapher Pro
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!
Pro version features
• Full complex calculations for 2D functions (i.e. plot a real + imaginary part) and standard expressions
• Variable sliders: adjust parameters to see their effect in real-time
• Choice between light and dark theme
• No ads
Curve types
• Function (cartesian)
• Polar
• Parametric
• Implicit
• 3D Function
• 3D Parametric curve
• 3D Parametric surface
More features
• Equation solver (numerical)
• Find roots, extrema and intersections with other functions
• Complex number support
• Real-time variable sliders
• Functions can reference each other
• Custom math keyboard
• Auto-detect input type
• User variable support for numbers and functions
• Editable parameter range (for polar & parametric curves)
• Input history
• Plot up to 24 graphs at once
• Light and dark theme
• 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.
Note: Complex equation solving will be supported soon in a next update.

I would like it to plot and determine the linear equation based on two sets of points x1,y1 and x2, y2. Doesn't work your formula, just gives me a horizontal line. I don't how you derived to this equation. I see the slope in the equation but the offset seems strange.

This is the first app I've ever rated, and I'm doing so because it is really amazing! Couple of things would be useful: variables with multiple letters; capability to graph complex functions in 3d...

I love this app, it really helped me graphically understand some calculus concepts. I would love to see a complex function plotter, for example for e^ix to be plotted as a circle, not as it's trig counterparts. Besides that wonderful

ASSIGN feature only works intermittently. Rest of app very good.

Awesome app, the best plotter I found for mobile! Only think I'm missing is an option to stash or save graphs and formulas for later to keep the app neat

Thanks man for this awesome application! You saved me a lot of times with your grapher (even the free version is fantastic). I'm glad of my purchase. Good job!

Beautiful app... simply the best..

Amazing app. But please look into this: #1 Bug: The functions I've defined can suddenly be assigned letters I haven't chosen, meaning f(a) might suddenly become b(a). #2 Allow us to quickly toggle the functions on the main screen. #3 Increase the length of a function if possible. #4 Allow us to easily save and load functions and variables, both on the main screen and on the "Variables/Functions" page. Thank you for a great app.
