Quick Graph vs GraphOE Graphing Calculator

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.

Welcome to GraphOE, It is a tool for graphing/plotting functions in 2D! We currently support the following features: 1. Explicit, Implicit, Parametric, and Polar graphs. 2. Region labeling of inequalities for explicit and implicit functions. 3. Adjustable variables and animations. 4. Auto intersections for explicit and implicit curves. 5. Point of interest like minima, maxima and inflection points, for explicit curves. 6. Cartesian(Rectangular) and Polar(Circular) coordinate system. 7. Intuitive zoom-in/zoom-out and panning. 8. Screenshots with various backgrounds for canvas. 9. Auto saving feature. Saves to the local storage. 10. Functions: sin, cos, tan, cosec, sec, cot, sinh, cosh, tanh, asin, acos, atan, asinh, acosh, atanh, log and exp 11. Intuitive equation editor with beautiful fonts. 12. Unlimited number of functions in single canvas. 13. Fully supported dark mode or any color background mode. 14. Scatter plots with point list Tips and Tricks 1. Touch near the intersection or point of interest to label them. 2. Change the background of the canvas to black to enable dark mode. 3. To create a scatter plot just add all the points like (1,2),(2,3), etc to the equation editor We hope that GraphOE will be useful for you in understanding the graphs of various functions.
