What Is a Countdown Timer?
A countdown timer starts from a selected duration and counts down toward zero. It can be useful when you need to work for a specific amount of time or want a reminder when a period has finished.
How to Use the Countdown Timer

Quick Countdown Presets
The timer includes several quick presets, including 1, 5, 10, 15, 30 and 60 minutes. These presets make it faster to start a common countdown without manually entering the duration.
What Are Lap Times?
Lap times allow you to record intermediate times while a stopwatch continues running. For example, you can record each lap during a running workout or each stage of an activity.
Online Stopwatch for Study

A stopwatch can be useful for measuring exercise intervals, running times, rest periods and sports practice. For activities where precise timing is important, use a timing device appropriate for the activity and conditions.
