KickCode (http://kickcode.com) has released WordTarget 1.2 for Mac OS X. The app sits in the menu bar and tracks a users word count across different applications.
Users receive a notification when they hit their target, and can start and stop tracking at any point. The app is on sale at a reduced price (US46.99 instead of $8.99) on the Mac App Store until Friday, Dec. 19. WordTarget requires Mac OS X 10.8 or newer.
