Online Stopwatch
A focused browser stopwatch for timing activities when you do not know the target duration in advance. 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.
What is a 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.
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.
Is this accurate enough for scientific timing?
It uses a monotonic browser time source for practical timing, but it is not a certified scientific instrument. Use dedicated hardware for regulated or high-precision measurement.
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.
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.
