Alarm Timer is a useful repeating timer, and simple alarm clock. Use it as a reminder to get up and take rest, time your egg, an exercise timer or even run an AppleScript(R) after the time is up. What makes Alarm Timer different is that you can have it signal to you continuously, without the need to constantly close dialog boxes. For an alert sound you can choose any sound located on your computer, even an AAC file or MP3 file. Alarm Timer also serves as a simple alarm clock.
