Quick Graph

April 11th, 2010 by admin

Quick Graph plots high quality 2D and 3D mathematical expressions. Graphs can be shaded with custom colors and in 3D the lighting is enabled to demonstrate the depth of the surface.

You can zoom in and out by pinching the image and pan around with one finger (2D) or two (3D). In both 3D and 2D modes, the graph adapts the evaluation limits when the touch gesture ends, allowing you to focus on specific features of the graph.

The 3D view allows for interactive rotation, translation and zooming by simple touch gestures. In addition, you can change from wireframe to solid visualization, with a simple double tap.

Quick Graph includes a wide variety of mathematical features and coordinate systems: Cartesian, Cylindrical and Spherical systems are supported for 3D equations, 2D equations support both Cartesian and Polar.

All graphs are automatically saved / restored whenever the application is closed / open.

Optional features

Even though all the standard features that made the original Quick Graph a great app are free, you can opt to unlock additional features (via in-app purchase), these features currently include tracing, implicit graphs (2D and 3D), inequalities (2D and 3D), unlimited graphs (limited by the available device memory) as well as all other features that will be included in the future. Upgrading Quick Graph’s additional features will not only enhance your user experience, but it will also support the developing of Quick Graph!


  • Support for a wide variety of standard mathematical functions.
  • 2D and 3D graphing of explicit equations in all supported coordinate systems, implicit equations(opt) and inequalities(opt).
  • Easy to use interface.
  • Cartesian/Polar coordinates in 2D.
  • Cartesian/Cylindrical/Spherical coordinates in 3D.
  • The coordinate system to use is inferred from the expression, there’s no longer need to specify it beforehand.
  • Plot multiple equations (up to 6 in the standard version), unlimited (opt).
  • Send email with the graphs you’re working on
  • Built in library with the ability to include custom equations
  • Easily zoom in and out on the graph
  • Copy the current graph to the clipboard
  • Built-in user manual
  • Tracing (trace the coordinates along the graphs) (2D opt)
  • Hyperbolic functions / inverses
  • Landscape and portrait support

    i like use is the tool best for study.

    This app is amazing and is proving to be very useful…

    Really good applications! I’m interested in the optional features but I did not find out how to buy it from my computer. I went to the quickgraph itunes-app store’s page but there is no link where I can buy the advanced features.
    How can I do?(I would rather buy it from my computer than from my ipod-touch)

    I love this app. I just wish I could ( or knew how I could) input multiple values for “y” like I can in a TI-84.

    I have an idea for a math education app that I think you can pull off and I believe it would make a lot of money. I use your quick graph app on both iphone and ipad often when I’m teaching and tutoring math students.

    I love this program! However, I would like to see it be VGA adapter compatible. I am an Algebra teacher and would like to have the ability to show my students the graphs on the projector.

    I second the VGA adapter compatibility request. As an instructor, it would be very valuable to project images on the screen.

    We are working on the VGA Adaptor and will be released in the next version of QG.

    Really excited to hear about plans to develop a version that is projector-compatible, as that’s what I really want to use for my teaching. Right now I’m using the free app, but when that feature becomes available, I will gratefully send money your way.

    I teach math and I purchased your version with the extras. Please update to projector ASAP so that I can get my students to purchase it too.

    How much is it possible?

    So when is this next version expected to be released?

    Our next version is to be send it to Apple at the second week of January. It would include the VGA output and another fixes.

    Our next release will be send to Apple the second week of January 2011. It would inclue the VGA output and bug fixes.

    It is great to hear that QG will be VGA adaptor compatible in the next version. As an educator, I simply love the abilities and potential this software has shown thus far. I think it would be perfect if QG can show 3D lines as well. It would be useful, for example, in the study of vectors (planes and lines etc).

    Great graphing program, I’m using it as a student in college for engineering calculus 3, which is 3-D graphing and calculus. As far as I’ve discovered, there’s no way to graph vector functions in this program. If there is, I’m an idiot and haven’t found them yet. Otherwise, please consider this for next update? I’d pay $1-2 to have that added.

    Looking for new version supporting VGA cable. Will there also be Retina display support?
