AlarmJ is a (really) small countdown timer with a minimalist interface. It can be set for up to 90 minutes and plays any WAV file when time expires. Whether you are taking a nap, cooking, or rationing out TV time to your kids, this free program makes it easy.
To install it just unzip AlarmJ (and the four wave sound files). AlarmJ doesnt require pre-installing any software or library on your machine.
