DssW has released Activity Audit for Mac OS X. The US$8.99 app creates a journal of the applications used on a Mac. It requires Mac OS X 10.6.7 or lataer.

Activity Audit creates calendar events as applications are launched and quit. These events create a complete audit trail showing users the applications they were using and when. The resulting calendar provides visual insight into how a user’s Mac has been used.

Activity Audit works with Mac OS X’s built-in calendaring support. The audit calendar is visible to iCal and other calendaring software. Activity Audit can create a new calendar to store events, or the user can specify an existing calendar.

Once started, the auditing process runs in the background and doesn’t require Activity Audit to be left running. The audit is restricted to the user who started the process, and that user can opt to exclude specific applications or entire folders of applications. By default, Activity Audit excludes applications located in the System and Library folders.

App Store .
