About this app

Grapher is a small, lightweight and useful graphing calculator and a function plotter for all pupils and students. The simple interface helps you to build any graph or function on a Cartesian coordinate system in just a few seconds. You can draw simple, parametric, polar or table types of math functions.

You can build multiple functions with Grapher at the same time on the same screen using different colors.

Grapher has the following features:
* zooming and dragging
* function list
* color picker
* simple interface
* many standard functions
* custom keyboard with all standard functions (like cos, sin, tg, sqrt, ln, log and so on)
* different types of functions:
* simple
* parametric
* polar
* table
* double tap zooming
* thumbnails
* more coming soon

Ratings and reviews

Very good - BUT. If you ask for graph of y = - log(1+.001x10^x), the result comes out exactly twice what it should be. E.g. log (base 10) of 1/2 is .3010.. not .6020. However, later this day, it gets it right. Therefore 5*. It must have been another app I was looking at which also does X - Y "parametric" plots ?

The app works too automatic to my liking. Can't use as a teaching aid. I'ld've preferred you made it also a teaching aid tool so that one can insert texts (ie points without the coordinates written)

Very useful. Intuitive to use. Nice for experimenting with curves that are otherwise laborious to plot and work with.
