A precise stopwatch with lap functionality for timing events.
Track time with precision using our free Online Stopwatch. Whether you're timing a workout, measuring cooking intervals, tracking study sessions, or running a race, this tool offers a simple and accurate way to measure elapsed time. It features a large, easy-to-read display and a lap function to record split times without stopping the main timer.
Measure time down to the millisecond (1/1000th of a second) for high-accuracy requirements.
Capture multiple split times (laps) to compare performance across different segments.
Zero lag start, stop, and reset actions ensure your timing is always exact.
Time your sprints, planks, or rest intervals during HIIT workouts.
Track how long you spend on specific tasks to improve focus and efficiency.
Ensure your steak is seared perfectly or your tea steeps for the right amount of time.
Measure reaction times or duration of chemical reactions in experiments.
Yes, the stopwatch uses the system clock to calculate elapsed time, so it remains accurate even if you switch tabs or minimize the browser window.
Practically, no. It can run for hours or days as long as you keep the tab open.
Currently, you can manually copy the lap times from the list. We may add an export feature in the future.
