Timing is a unique new time tracking application for your Mac. Via the menu item, it will automatically track which applications you are using and which documents you are working on. You do not have to start any timers - just focus on working, Timing does all the tracking for you.
To analyze how you spent your time, Timing allows you to filter your activities by date and duration and assign activities to projects.
If some applications and/or documents shouldn't be tracked, you can add them to the blacklist.
