Quick Graph

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!
