Accurate elapsed time
This stopwatch calculates elapsed time from timestamps, so background-tab throttling does not make the clock drift. Record laps, compare fastest and slowest splits, and resume after a reload.
How to use
- 1.Start the stopwatch and record laps as needed.
- 2.Pause or resume without losing elapsed time.
- 3.Name and save a session, then export history as JSON or CSV.
Local floating display
Saved sessions remain in local browser storage. Document Picture-in-Picture provides a floating display where supported, with an in-page fallback everywhere else.
