AppTracker

AppTracker tracks and logs the active application (in front of all other applications) while you use your Mac.

• Start it and forget it!
• Active time graph shows how long each application has been the active application.
• Use it for billing purposes.
• Export the data as tab-delimited.
• Set the main window to be translucent when it goes into the background so it won't be in your way.
• Easily clear the display by clicking the Delete All button.
