A precise, drift-free stopwatch with lap splits and a countdown timer that beeps when time is up — no installs, no sign-ups, running entirely in your browser.
| Lap | Split | Total |
|---|
Uses timestamp-based timing (requestAnimationFrame) so it stays accurate with no drift. Splits show each lap's individual time; total shows elapsed time at that lap.
Set minutes and seconds (or tap a preset), then Start. A beep plays when the timer reaches zero. Timing is timestamp-based, so it won't drift.
