Stopwatch

About the Stopwatch

A stopwatch is one of those tools you need surprisingly often — timing a workout, a task, an experiment or a lap — and hunting for a physical one is a waste of time when your browser can do it precisely.

This online Stopwatch is precise, records lap times, and is free with no signup, working on any device.

How to use the Stopwatch

1. Press start to begin timing.
2. Record lap times as you go.
3. Pause or stop when finished.
4. Read the total and lap times.

How the Stopwatch works

These tools implement well-established productivity methods — such as the Pomodoro Technique for focused work, structured to-do and planning workflows, and habit and goal tracking. Where a tool saves your data, it uses your browser's local storage, so your notes, tasks and progress stay on your own device and are there when you return.

Tips & best practices

• Use lap times to compare splits — handy for training, cooking stages or repeated tasks.
• Keep the tab active while timing for the most accurate result.
• For counting down to zero rather than up, use the Countdown Timer instead.

Standards & accuracy

Built on proven productivity methods (such as the Pomodoro Technique) with data stored privately in your browser.

Because data is stored locally in your browser, it is private but tied to that device and browser — clearing your browser data will remove it, so export anything important.

Who uses the Stopwatch?

• Timing workouts and intervals
• Recording lap or split times
• Timing tasks and experiments

Privacy & security

The Stopwatch runs entirely inside your web browser. Your data — whether that is a file, figures or text — is processed on your own device and is never uploaded to a server, stored or shared. There is no signup and no account, so you can use it as often as you like while keeping full control of your information. This makes it a safe choice even for confidential and sensitive work.
