Description

XPP is an app for solving differential equations, delay equations, functional equations, boundary value problems, and stochastic equations.

It is based on the popular program XPPAUT and uses the same ODE file syntax. The interface has been completely rewritten for the iPhone.

XPP will draw nullclines, direction fields, and two- and three-dimensional plots of solutions as well as find equilibrium points, their stability and separatrices.

Users can choose from a dozen different numerical integrators.

Computed data can be exported via iTunes.

Using the sliders, it is possible to watch how the behavior of the system changes as parameters vary.

Solve all your differential equations problems with XPP.

Add any of thousands of equations to your library directly from the WWW or import via iTunes.

Not bad, could still be improved

The app is great at plotting curves and finding equilibria, as well as allowing me to edit ODE files.

However, I did have some trouble obtaining eigenvalues of equilibria; when it did choose to work, I could only get the result after several repeated attempts at finding equilibria. Also, video tutorials would be helpful, as there's so much to do, jam-packed into this app. A separate app/paid extension for Auto/Bifurcations software would also be very useful.

Overall, still a good app. I would recommend for the convenience.

Great app!

This is great! So glad this was done. Solve odes and ddes on your iPhone. I feel like having a smartphone is actually worth it now.

Excellent!

A great little piece of software for plotting solution curves to ODEs
