Temporizador
Un temporizador de cuenta atrás con varios temporizadores simultáneos. El tiempo restante se calcula desde la hora de fin absoluta, por lo que se mantiene preciso en pestañas en segundo plano.
No timers yet. Add one above.
Cómo usar
- Enter a label and hours/minutes/seconds, then Add timer. The countdown starts immediately.
- Each timer can be paused, resumed, reset or deleted independently.
- When a timer finishes it beeps and its card flashes.
Notas
Remaining time is always computed as end time minus now, so timers stay correct in background tabs and across page reloads. The timer list is stored in this device's local storage and never sent to a server. Sound becomes available after you interact with the page, per browser rules.
Preguntas frecuentes
- Will it beep if I close the tab?
- No. The tab must stay open for sound. If you reopen it later, the timer correctly shows as finished.
