Stopwatch

The display updates every centisecond (0.01 s) and timing is based on high-resolution timestamps, so it doesn't drift even if the browser momentarily slows down. It's precise enough for interval training, cooking, speeches and classroom activities.

Laps record split times without stopping the clock — ideal for tracking per-round performance in workouts or comparing how long each task took. The fastest split is highlighted in green, the slowest in red.

Yes, as long as you stay inside TimeSpeedy — the stopwatch keeps running while you use other tools. A full page reload resets it.
