Turn iTunes into an alarm clock with iWatch

iWatch is a four-task application that is able to act as a kitchen timer, an alarm clock, a stopwatch with lap memory, and a clock displaying the time and computer uptime. iWatch also features “actions” which allow for various possibilities for timers or alarms with options for displaying system alert messages and beeps, playing sound files, playing QuickTime movies, triggering iTunes to start or stop, and even telling the computer to sleep, restart, or shut down.
