Online Stopwatch with Lap Times

A stopwatch is an essential tool for sports, fitness, cooking, productivity and any situation where you need to measure elapsed time. This online stopwatch is precise to the hundredth of a second and includes full lap time tracking.

Unlike many basic stopwatches, this one lets you record individual lap times while the total timer keeps running. Each lap shows both the split time (time for that lap alone) and the cumulative total, making it easy to compare performance across intervals.

How to use the stopwatch

Press Start to begin counting. While running, press Lap to record the current time without stopping the stopwatch. Press Pause to temporarily stop, and Resume to continue. Press Reset to clear everything and return to zero.

Use cases

Athletes use lap timers to track split times during track runs, swimming lengths, or cycling laps. Coaches use them to compare performances. In the kitchen, a running stopwatch helps you time multiple dishes simultaneously. For productivity, it helps measure how long tasks actually take compared to estimates.
