2D ODE Grapher

This app plots 2-dimensional systems of ordinary differential equations as vector fields. It allows you to plot solution curves through a point by tapping the plot. It also finds equilibria, calculates the Jacobian (and its eigenvalues and eigenvectors) at the equilibrium and determines the type of equilibrium. You can use up to 6 parameters to describe your ODE and the bounds of your plot can depend on these parameters. You can also zoom and pan around the plane with gestures.

The help section in the app contains more detailed information on how to use the app.
