## Description

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 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.<br><br>The help section in the app contains more detailed information on how to use the app, its limitations, and features that will be coming soon.<br><br>This app is still being developed. Please send feedback to planar.odes.app@gmail.com.
