KineSim

    In this program, which I made together with my girlfriend, you enter a set of coupled reactions, each with a kinetic constant. Then, the program runs a simulation (based on the Euler method) that returns the concentration (or some property which is directly proportional to it, the proportionality constant being given by you) of each species as a function of time. This is ideal for visualizing complex kinetic mechanisms and for checking equations derived by hand.

    Besides, you can open a file with experimental data to plot it over the simulation; and you can copy data to clipboard in a format suitable for MS Excel and Sigma Plot.
