Free Time Tracker - Timing lite 1.1

Timing is the best way to keep track of the time you spend with your Mac. Find out where your time goes - without ever having to start a timer again.
Timing automatically tracks which documents you are editing, which applications you use, and the domains of the websites you visit. You'll never have to worry about forgetting to start or stop a timer again - there are none. It's all done in the background.
