Online Stopwatch

This online stopwatch measures elapsed time and lap splits for coaches, presenters, teachers, and anyone timing an activity without a set finish time. Start from zero, pause and resume cleanly, record lap times, and reset for the next run. The stopwatch runs locally in your browser, keeps the first screen on the tool, and stays readable for classrooms, presentations, coaching, workshops, and simple desk timing without signup or ads. Use it when elapsed time matters more than a deadline: rehearsal sections, exercise rounds, classroom challenges, facilitation drills, QA sessions, or any task where you want a clean count-up display instead of a countdown.

What is an online stopwatch used for?

  • ✓Classroom activities where the group is measuring how long a task takes instead of counting down to a deadline.
  • ✓Presentation rehearsals and practice talks where speakers need elapsed time plus lap markers for sections.
  • ✓Coaching, workouts, drills, and informal challenges where lap times help compare rounds.
  • ✓Workshops, facilitation exercises, and live demos where the timer should count up from the moment an activity starts.
  • ✓Desk timing for calls, focus blocks, experiments, cooking prep, and other everyday tasks that need a clean stopwatch.
  • ✓Shared-screen timing where the display needs to stay legible for remote viewers without exposing a dashboard or account.

How it works

  1. 1

    Start, pause, and resume

    Press Start when the activity begins. Pause freezes the elapsed time; Resume continues from that same value. Press Reset to return the elapsed time to zero and clear the lap list before another run.

  2. 2

    Record and compare laps

    Press Lap while the stopwatch is running at each section or round. Each record shows the total elapsed time at that mark and the split since the previous lap; the newest lap appears first.

Frequently Asked Questions

Is this stopwatch free?

Yes. EasyTimer.app's online stopwatch is free, runs in your browser, and does not require an account.

Does the stopwatch support lap times?

Yes. Press Lap while the stopwatch is running to record the current elapsed time. The latest lap appears first, with a split delta from the previous lap.

Can I pause and resume the stopwatch?

Yes. Pause freezes the elapsed time, Resume continues from the same value, and Reset clears both elapsed time and laps.

How accurate is this stopwatch for general use?

It calculates elapsed time from the browser’s monotonic clock source and is suitable for practical, everyday timing. It is not a calibrated measurement instrument.

Can I use the stopwatch fullscreen?

Yes. The display is designed for large screens and projected views. Browser fullscreen support depends on your device and browser.

Can I customize the stopwatch display?

Yes. The stopwatch uses the same visual settings system as the main timer, so you can adjust label text, color, font, size, position, and shareable URL settings for the room or screen.

Does the stopwatch keep timing if the tab is backgrounded?

Elapsed time is computed from the browser’s monotonic performance clock. Browsers may throttle display updates in background tabs; when you return, the stopwatch recomputes elapsed time and catches up instead of counting missed display ticks.

Is this the same as the OBS timer?

No. This page is a standalone count-up stopwatch. The OBS pages are countdown-focused browser-source tools and setup guides.
