You can specify one or many programs to monitor.
Does that user really use Photoshop? They claim they do. With ARWatchDog you will know how often and for how long a user uses that expensive piece of software. With this knowledge you can move the software to another computer, buy more licenses, and easily convince the "powers that be" that the money needs to be spent.
