Is there a time limit?

No. The stopwatch can run for hundreds of hours.

The page does not store times, but you can copy your lap times into your notes.

Does the stopwatch show milliseconds?

No. It shows time to 1/100 of a second (hundredths), not milliseconds. Actual precision depends on your device's processor speed.

Does the stopwatch work without internet?

Yes. Once the page has loaded, it keeps working in most browsers even if the connection drops.

Why should I use this instead of my phone's built-in stopwatch?

When you work at a computer, you can see the elapsed time in large figures on screen without reaching for your phone.

Online Stopwatch Accurate to 1/100 Second

This online stopwatch runs in your browser with nothing to install and shows time in seconds and hundredths. Use it to time running laps, keep track of presentation segments or time any activity to under a second.

Lap Recording Feature

For activities with several stages, the 'Lap' button records how long each section takes. Runners, swimmers and people running lab experiments can then compare laps or stages side by side.

Using for Pomodoro and Productivity

With time management methods such as Pomodoro, a stopwatch that counts up shows how long you actually stayed focused. Seeing the real length of your work sessions helps you adjust your routine.

Mobile-Friendly and User-Friendly Interface

The tool works on phones too, so you can use it during training. The 'Start', 'Stop' and 'Reset' buttons keep it simple. The fastest and slowest laps are marked automatically, so you can compare earlier laps.
