Free Online Stopwatch
Measure time with hundredths of a second precision
What Makes This Stopwatch Special
Timerlyn's online stopwatch was designed with a focus on precision and practicality. Unlike physical stopwatches or apps that need to be installed, our tool is always available in your browser, ready for immediate use. The large, crisp display shows hours, minutes, seconds and hundredths of a second, ensuring you have the level of detail needed for any type of time measurement.
The lap function is an important differentiator for anyone who needs to record multiple time intervals in a single session. Each lap records both the split time (since the last mark) and the cumulative total time, allowing for detailed performance analysis. Whether for running laps on a track, gym exercise sets or tracking stages in industrial processes, the lap recording provides the data you need.
How to Use the Stopwatch Step by Step
- Click the "Start" button to begin timing. The stopwatch will start measuring immediately with hundredths-of-a-second precision.
- To record a split lap, click "Lap" without stopping the stopwatch. The lap time will be recorded in the table below, showing the split time and the cumulative total time.
- Click "Stop" to pause the count at any time. You can resume the count from where it left off by clicking "Start" again.
- Use the "Reset" button to clear the stopwatch and all recorded laps, preparing it for a new measurement.
Tips for Getting the Most Out of It
To view the stopwatch from a distance — such as during group workouts, presentations or classes — activate fullscreen mode by clicking the corresponding button. The display will fill the entire device screen, making it easy to read even from several meters away. This feature is especially useful for coaches, teachers and instructors.
If you need to time activities regularly, consider bookmarking this page for quick access. The stopwatch works on any device with a modern browser — computers, tablets and phones — maintaining the same precision and functionality across all of them. Remember that the stopwatch continues running even if you switch browser tabs.
