A simple, accurate stopwatch in your browser
Sometimes you just need to time something, a workout interval, a presentation rehearsal, a cooking step, without hunting for a phone or installing an app. This online stopwatch starts instantly in your browser, records lap times, and stays accurate to hundredths of a second. There is no signup and nothing to download.
How to use it
- Start and pause with a single button as you go.
- Record laps: each lap shows both the split since the last lap and the total elapsed time.
- Reset to clear the clock and the lap list when you are done.
Built to keep accurate time
It uses a high-resolution browser clock and keeps counting smoothly even while you record laps, so it does not drift the way a naive timer can. It also keeps running reliably when the tab is in the background, which matters if you switch away mid-timing. Reloading the page starts fresh, so keep the tab open while you are timing something.
More time tools
If you need to count down to a moment rather than up from zero, try the countdown timer, and for scheduling across zones there is the meeting planner. Every Etoolio time tool runs in your browser, free and with no signup.
