Stopwatch

00:00.00

Keyboard: Spacestart/stop · L lap · R reset

Laps (0) — newest first · best in green, worst in red

No laps yet — press Lap (or L) while the stopwatch is running to record a split.

Timing uses performance.now() deltas sampled every 33 ms, so the display stays accurate even if an interval tick is delayed. Everything runs in your browser — nothing is uploaded.
