Run a Stopwatch or Countdown Timer
Start a stopwatch, record laps, or set a countdown for workouts, cooking, study blocks, meetings, practice sessions, and focused work intervals.
Use Laps and Pauses Deliberately
Lap times help compare repeated rounds, while pause and reset controls keep timing clean when you stop between tasks or restart a session.
When Browser Timing Helps
Use it for quick timing when you do not need a dedicated app: exercise sets, speeches, rehearsals, Pomodoro-style work, classroom tasks, or kitchen reminders.

Frequently Asked Questions
Can I record multiple lap times?
Yes. Each click of the Lap button records the current elapsed time and the time since the previous lap, building a list of splits.
Is the stopwatch accurate?
The stopwatch uses the browser's high-resolution performance timer for millisecond accuracy. Background browser throttling may affect accuracy if the tab is inactive.
Can I use this on a mobile device?
Yes. The stopwatch works in any modern mobile browser. Keep the screen active to prevent the browser from throttling the timer.
