Final Countdown

Final Countdown is a cocoa application that gives you the possibility to start as many timers as you like. A timer can be a standard countdown for a user-defined number of days-hours-minutes-seconds or a countdown to a user-defined date (day-month-year and hour-minutes-seconds). When the timer fires, you can choose to be notified by a beep or an alert sheet, to launch an app or a script or to shut down your computer.
