Fruitful Time Productivity Meter tracks the active versus idle time, how your active time is split among applications, which applications were used the most, and which websites you browsed and for how long. You can review the stats for the last day, week, month or a user defined block of time. One of the most useful features is the ability to tag programs, windows, and domains.
The Business Edition allows users to track activity on several computers so now you can know exactly how much time your employees spend on facebook.
