What is Stopwatch & Timer?

Stopwatch & Timer is a free, easy-to-use online tool that allows users to measure elapsed time and count down from a set duration — all directly from their web browser, without the need to download any app or software. It typically combines two functions in one interface: a stopwatch that starts, stops, and records lap times, and a countdown timer that alerts users when a specified period has ended. Designed for convenience and simplicity, it is widely used by students, athletes, teachers, professionals, and anyone who needs quick and accurate time tracking. Being web-based means it is accessible from any device — desktop, tablet, or smartphone — making it a handy everyday utility for tasks like study sessions, workouts, cooking, presentations, and much more.
