What is a Countdown Timer?
A countdown timer is a tool that counts down from a specified duration to zero. When the timer reaches zero, it alerts you with a sound or notification. Unlike a stopwatch that counts up, a countdown timer lets you set exactly how much time you need and then tracks the remaining time until completion.
Common Uses for Countdown Timers

Study Sessions
