About Online Stopwatch with Lap Timer

Last updated: July 2026

The Stopwatch & Lap Timer Online tool gives you a precise, millisecond-accurate stopwatch in your browser. Start, stop, pause, and reset the timer with a single click, and record multiple lap times to track split times for races, workouts, cooking, experiments, or any timed activity.

A browser stopwatch is always available without downloading an app, and the lap timer makes it useful beyond simple timing - you can track individual split times for each lap or interval and compare them at a glance. The recorded lap list stays visible so you can review all splits without losing the running total.

2. Click Lap to record a split time without stopping the main timer.
3. Click Stop to pause the stopwatch.
4. Click Reset to clear the timer and all recorded laps.
5. Review the lap list to compare split times.

Best For:

• Timing athletic events, running laps, or workout intervals
• Recording split times for races or timed competitions
• Timing cooking steps or laboratory experiments
