Frequently asked questions
- Will the alarm sound if I switch to another tab?
- Yes. The timer counts down to a fixed end time, so even if your browser slows the tab down in the background, the alarm sounds when the time is up and the tab title shows the remaining time. Keep the tab open and your sound on.
- Why do I need to press start before the alarm works?
- Browsers only allow sound to play after you interact with the page. Pressing Start (or any preset) unlocks audio so the alarm can ring when the countdown ends.
- Can I use the timer full screen?
- Yes. Press the Fullscreen button to expand the countdown to fill your screen — useful for classrooms, presentations, workouts and cooking.
- Is this online timer free?
- Completely free, with no account or download. It runs entirely in your browser.
