Stopwatch Online — Free Browser Stopwatch
A free online stopwatch measures elapsed time with start, pause, reset, and laps. It runs in your browser—no extension, no account. If you need time counting down to an event, use the online countdown or a preset timer instead.
What is a stopwatch online?
An online stopwatch is a browser tool that counts elapsed time from the moment you start it. People use stopwatches for workouts, classroom activities, cooking tests, presentations, and productivity experiments. Because this tool is a stopwatch—not a countdown—it always counts upward until you pause or reset.
Stopwatch vs countdown vs timer
- Stopwatch — measures how long something took (this page).
- Countdown — counts down to a date/time (online countdown).
- Preset timer — counts down from a fixed duration (timer directory).
Frequently asked questions
What is an online stopwatch?
An online stopwatch measures elapsed time from when you press start. Unlike a countdown, it counts up and is useful for workouts, cooking tests, speeches, and timing tasks.
Is this stopwatch different from a countdown timer?
Yes. A stopwatch measures how long something takes. A countdown timer counts down to zero from a set duration or event date. Use this page for elapsed time; use the online countdown or timer tools for countdowns.
Does the stopwatch work offline after loading?
After the page loads, timing runs in your browser using your device clock. You do not need an account, and you do not need to install an app.
Can I record laps?
Yes. Press Lap while the stopwatch is running or paused with a non-zero time to save cumulative elapsed times. Reset clears the display and lap list.
