What is a countdown timer?
A Countdown Timer is an easy-to-use online tool where you can set a time with seconds, minutes and hours. The timer will count down from the set time to 0 and then play an alarm sound.
Change the settings to use a different alarm, set the length of the alarm or to put online timer in silence sound mode. It's also possible to immediately restart the timer after it's finished.
You can use the online timer as alarm clock in the kitchen to boil the perfect egg, to measure screen time limits for your kids or as timer for sport games.
