Stopwatch & Timer

Sometimes you just need to time something — a workout set, a boiling egg, a speech rehearsal, or how long a task really takes. This tool combines a precise stopwatch and a countdown timer in one place, with no app to install.

Stopwatch

Start, pause, and reset a stopwatch that counts up to hundredths of a second. Press **Lap** to record split times without stopping the clock — useful for timing repeated efforts like laps, sets, or rounds, and comparing them side by side.

Countdown timer

Switch to the Timer tab, set any number of minutes and seconds, and start a countdown. You get a clear on-screen alert when it reaches zero — handy for cooking, interval training, presentations, and focused work sprints.

Accurate in the background

Both modes are based on real elapsed time rather than a naive tick counter, so they stay accurate even if the browser tab goes to the background or your device briefly sleeps.

No signup, no ads on the tool, and nothing leaves your device — the timing all happens in your browser.
