Frequently Asked Questions
- How do I set a 24 hour timer?
- Press Start on the timer above and it counts down 24 hours. You can pause, reset, or edit the time, and an alarm sounds when it reaches zero.
- Does the 24 hour timer play a sound?
- Yes. When the countdown finishes, an alarm sound plays. You can choose between a chime, beep, or bell.
- Will the timer keep running in the background?
- The timer is accurate even if the tab is in the background because it counts down from a fixed end time rather than ticking one second at a time. Keep the tab open to hear the alarm.
