Quick Graph 4: a new design, smooth Metal 3D, equation groups, Apple Pencil annotations and graphs you can share as a link. Ready for iPhone Duo.
Quick Graph is a powerful, high-quality graphing calculator for iPhone and iPad, in 2D and 3D.
"The app you need to survive the next semester."
-- Gizmodo
Type an equation and see it right away, written in math notation and drawn in a graph you can move, zoom and rotate with your fingers. Explicit and implicit equations and inequalities, in cartesian, polar, cylindrical and spherical coordinates, all fast and beautiful.
What's inside:
- 2D and 3D graphs with a clean, full-screen design.
- 3D surfaces drawn with Metal: smooth shading, transparency, wireframe, and zoom that fills the screen.
- Adaptive 2D drawing with exact roots and extrema and clean asymptotes.
- Equation groups: show, hide and move several equations together, with a shared n.
- Annotations with Apple Pencil or your finger on 2D graphs.
- A math keyboard with functions, derivatives and more on each key.
- Hyperbolic and inverse functions, min, max, if, derivatives.
- Axes in decimals or multiples of π, and independent zoom on each 2D axis.
- A library of example and saved equations, including groups.
- Share as a link, image or text; copy and paste equations; drag them between windows.
- Light or dark appearance, multiple windows on iPad, and support for iPhone Duo.
Up to 6 equations can be shown at once in the free version. The Advanced Features, a single one-time purchase with no subscription, add:
- More than 6 equations.
- 2D and 3D implicit equations and inequalities.
- The variable n with a slider, to animate your graphs.
- 2D tracing with roots, extrema and intersections.
- Value table.
- External display support.
- Decimal / π axes and polar range settings.
No ads, no subscription. Please visit the website for more details.
You can draw any equation you want and in 3d! Try it out!
Quick Graph 4 is the biggest update yet.
• A new look: floating controls leave the whole screen to the graph, on iPhone and iPad. Light or dark, your choice.
• Smoother 3D: surfaces drawn with Metal, with smooth shading, transparent colors, and zoom that fills the screen.
• More precise 2D: exact roots and extrema, and no more lines across asymptotes.
• Equation groups: show, hide and move several equations as one, with one n for the whole group or one for each.
• Annotations: draw on your 2D graphs with Apple Pencil or a finger. They stay in place as you pan and zoom.
• Share a graph as a link that opens right in Quick Graph.
• A redesigned keyboard: same keys, a cleaner look. Hold a key with a corner tick for more.
• New examples in the library, and a quick way to restore the originals.
• Ready for iPhone Duo, Split View and Stage Manager.
