A clean, free stopwatch with lap times. Press Start (or the spacebar) to begin.
This is a precise, browser-based stopwatch — nothing to install. Click Start to begin timing and Stop to pause; the display keeps hundredths of a second. Hit Lap to record a split without stopping the clock — each lap shows both the lap time and the total elapsed time, newest at the top. Reset clears everything back to zero.
Keyboard shortcuts: Space start/stop · L lap · R reset. Use Full screen for a big, room-visible display — handy for workouts, classrooms, science experiments, cooking and games.
