# Graphing Calculator Alternatives

Graphing Calculator is described as 'Graph functions in two, three, and four dimensions, explicit, implicit, or parametric. Graph inequalities, contour plots, density plots and vector fields. Use rectangular, polar, cylindrical, or spherical coordinates. Solve equations numerically, graphically, or symbolically' and is an app in the Education & Reference category. There are eight alternatives to Graphing Calculator for a variety of platforms, including Mac, Windows, Online / Web-based, Linux and Android Tablet. The best alternative is GnuPlot, which is both free and Open Source. Other great apps like Graphing Calculator are Grapher (Free), GeoGebra Graphing Calculator (Free, Open Source), MathMod (Free, Open Source) and GeoGebra CAS Calculator (Free, Open Source).
