MathGraphs

Education

$0.99 · Designed for iPad. Not verified for macOS.

Graph circles, conics and spirals — any equation in x and y, not just y = f(x). Works offline, with no account and no ads. MathGraphs draws equations that ordinary graphing apps cannot. Most graphers need y on its own: you give them y = f(x) and they plot it. MathGraphs takes the whole equation, in the form f(x, y) = g(x, y), and finds every point that satisfies it. That means circles, ellipses, hyperbolas, cubics, spirals and implicit curves that cannot be rearranged into y = something. Type x^2 + y^2 = 5 and you get a circle. Type y = x*tan(ln(sqrt(x^2 + y^2))) and you get a spiral. Neither is a function of x, and both plot in the same way. HOW IT WORKS Both sides of your equation are parsed and evaluated across a fine grid, and the curve is traced wherever the two sides balance. The resolution follows the size of your screen, so the curve stays smooth as you zoom in. WHAT YOU CAN TYPE • Trigonometric: sin, cos, tan, asin, acos, atan, atan2, sinh, cosh, tanh • Exponential and logarithmic: ln, log, exp, and the constant e • Also: sqrt, abs, sign, floor, ceil, round, max, min, mod, pow, and pi • Powers with ^, associating to the right, so 2^3^4 means 2^(3^4) • Products written naturally: 2x, 3(x+1) and 2sin(x) all work The four range boxes accept expressions too, not just numbers — 2*pi, pi/2 and sqrt(2) are all valid, so you can frame a trigonometric curve exactly. MOVING AROUND Drag to pan. Pinch to zoom. Widen or narrow the range a step at a time, or square the axes so a circle looks like a circle. The range boxes follow along as you move, and you can type into them at any point to jump somewhere precise. ALSO INCLUDED • An expression calculator that evaluates f(x, y, z) at values you choose • Fourteen worked examples, from conics to a logarithmic spiral • A built-in syntax reference, so you are never guessing at notation • Save the graph as a picture, straight to Photos, Files or Messages • Three colour themes: Midnight, Daylight and Blueprint PRIVATE BY DESIGN MathGraphs works entirely on your device. It has no accounts, no advertising, no analytics and no network access of any kind, so it works in airplane mode and there is nothing to collect. Suitable for all ages. Universal: runs on iPhone and iPad.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Version 2.0 is a complete rewrite. The original MathGraphs was built on Adobe Flash, which iOS no longer supports. Everything has been rebuilt from scratch — the parser, the plotting, and the whole interface — so the app runs natively on current iPhones and iPads. WHAT IS NEW • Rebuilt for modern iOS, with a display that fits every current iPhone and iPad size • A faster, more accurate plotter: the curve is drawn from a much finer grid and stays smooth as you zoom • Drag to pan and pinch to zoom, with the range boxes updating as you move • Three colour themes — Midnight, Daylight and Blueprint — remembered between launches • Save your graph as a picture to Photos, Files or Messages • A wider expression language: sinh, cosh, tanh, log, exp, sign, mod, atan2 and pow join the original set • Range boxes now accept expressions such as 2*pi and sqrt(2), not only plain numbers • Products can be written naturally: 2x, 3(x+1) and 2sin(x) • Clearer error messages that say what is actually wrong with an equation • A built-in syntax reference and fourteen worked examples Still no accounts, no adverts, no tracking and no network access. Everything runs on your device.
