Perfect Alarm Clock is a free software that enables you to set infinite number of alarms, triggering on a one time, daily, or weekly basis. Perfect Alarm Clock not only plays any audio file you specify (mp3, wma, etc), but can also be used as a scheduler, to launch any application at a specified time. The program's user-friendly interface makes the operation very easy. Setting an alarm is as easy as selecting a file to play, selecting the alarm type and time, adding remarks (optional), and adding the alarm to the alarms list. You can further test each alarm item, e.g., to adjust the speaker volume. Perfect Alarm Clock minimizes to tray and runs in the background, occupying no space on your desktop, and using minimal system resources (0% cpu usage and only about 1MB memory usage).
