About This Tool

A stopwatch for timing anything you're doing right now, from a workout set to a cooking timer to how long a meeting actually runs. It uses high-resolution browser timers, so it stays accurate even if the tab sits in the background, and nothing you time is ever logged or sent anywhere.

Frequently Asked Questions

Is this stopwatch accurate?+
Yes. It uses high-resolution browser timers (performance.now() and Date object deltas) to track elapsed time with millisecond precision, independent of browser lag or background page throttling.
Can I save my laps?+
Laps are kept in local memory while you keep the tab open. Since everything runs client-side for privacy, refreshing or closing the tab resets the laps.
Does it work offline?+
Yes! Once loaded, the stopwatch and all its features function completely offline without any internet connection.
