Quick Graph vs EzyGraphs

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.

EzyGraphs is a easy-to-use mathematical graphing tool with lot of unique features. FEATURES + Accurate display of mathematical notations + Intuitive keyboard + Graph analysis, e.g. domain, zeros, min/max/inflexion points + Graph customising with colors and line styles + Trace to find coordinates and intersections + Supports latest iOS features: adaptive to all screen size, iPad multitasking "Excellent and very useful." [IR MANSON from US, Apr 28, 2015] "Ezygraphs can handle all the 2D functions I'll ever need to graph. There is no delay from entering the function to graphing it. It allows for multiple functions. I can find coordinates of points. There's even an option to view recent functions. Possibly the greatest mobile graphing app there is." [hansenjiang from Canada, Aug 27, 2015] "This is by the best looking and the most amazing graphing calculator app ever. Just love it." [Majeeb12 from Canda, Apr 07, 2015]
