Good to know
What is a lap, and what is total time?
A lap measures the time since the previous lap. Total time is measured from the start, excluding pauses. The current unfinished lap is shown on the display; CSV includes only recorded laps, in their original order.
Does it work in another tab or after reloading?
Background delays do not accumulate: elapsed time is recalculated. Reloading restores the session if tab storage is available. After sleep or reloading, recovery uses your device clock; changing that clock can affect the result. Hundredths are a display resolution, not a guarantee of laboratory precision.
Where are my results saved?
This stopwatch saves its session in this browser tab, without an account or cross-device sync. Closing the tab or clearing browser data can remove it. Export the recorded laps to CSV to keep a separate copy.
