The Tickline 40 minute timer is a free, distraction-free countdown of 40 minute. 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 40 minute — 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 40 minute timer preloaded for the other person.

Does it work if I switch tabs?
