This is a basic 5 minute countdown timer that counts back in seconds. It starts at 300 and when it reaches zero you will hear 3 loud noises on your computer. It has 3 buttons Start, Stop, Reset. The start button will start the timer, the stop button will stop or pause the timer. The pause feature on this countdown timer is good because there are times when we need to stop the timer in case of interruption's. The reset button will reset the timer back to 300 which is 5 minutes. The user interface is very basic and easy to use. The download size of this software is very small and will not require much room on your PC.
