JWatcher is a powerful tool for the quantitative analysis of behaviour. It can be used to address any theoretical problem that requires a complex sequence of actions to be scored by a human observer.

JWatcher can be used simply as an event recorder which logs the time at which keys are pressed. It was designed primarily for focal sampling, in which a single subject is observed continuously. The real power of JWatcher is, however, in its analysis routines. These calculate time budgets and provide statistics about the duration of behavioural states and the intervals between them.
