Each stopwatch is independent. Browser-local restoration uses the device wall clock across reloads, so this is convenient timing rather than certified race/lab timing.

How to use this Multi Stopwatch

Add several labeled stopwatches and start, pause, reset, or mark them independently. Start/Pause all is useful when several participants or activities begin together, and the board is restored locally.

Timing accuracy and persistence limits

Cross-reload restoration uses the device wall clock, while visible updates use browser timing. This is a convenience utility for parallel activities, not certified race, scientific, or legal timing equipment.
