The Tickline 30 second timer is a free, distraction-free countdown of 30 second. Press Start (or the Space bar) and the alarm rings when the time is up. It's built for anything that needs a quick, reliable 30 second — cooking, workouts, study intervals, quiz rounds, meetings, or breathing exercises. The countdown is anchored to a real end-timestamp, so it stays accurate even if you switch tabs. You get four alarm sounds, optional voice cues, ambient noise, a fullscreen mode, screen wake-lock, and Copy-link URLs so a shared link opens the identical 30 second timer preloaded for the other person.
Frequently asked questions

Yes. When the countdown reaches zero the alarm loops until you press Dismiss.
Does it work if I switch tabs?
Yes — the countdown uses a real end-timestamp, so a background tab stays accurate to the millisecond.
