What is Stopwatch & Timer?
The Stopwatch & Timer tool provides two essential time management functions. The Stopwatch measures elapsed time with millisecond precision, allowing you to record 'Laps' (splits) without stopping the main timer. The Countdown Timer allows you to set a specific duration (e.g., 5 minutes) and alerts you when time is up. It's perfect for workouts, cooking, study sessions, or tracking work tasks.
