타이머
여러 타이머를 동시에 사용할 수 있는 카운트다운 타이머입니다. 남은 시간을 절대 종료 시각 기준으로 계산하므로 백그라운드 탭에서도 정확합니다.
No timers yet. Add one above.
사용 방법
- 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.
참고 사항
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.
자주 묻는 질문
- 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.
