From Grau Software:
CountDown has 4 different individual timers that counts the time down for your specified task, then displays a message and sounds an alarm (WAV file). Included is a CountDown timer (can also run like a stop-watch), a CountUp timer (can also run like a stop-watch), Date CountDown which counts down up to 10 different dates and a Full Screen CountDown, which runs like a screensaver for timing classroom or sporting events. Also included are many background skins and an "Always On Top" feature. New features include running multiple timers at the same time and individual notepads for each timer.
