    Frequently Asked Questions

    Will the timer keep running in the background?

    Yes — the timer runs on real (clock) time, so the time stays correct even if you open another tab. But if you close the page, the timer will stop.

    Why did the alarm not sound?

    If your phone is on silent, or the browser has blocked sound, the alarm will not sound. First test a short 10-second timer, and keep the sound on.

    Is it completely free, and do I need an app?

    Completely free — no app, signup or download. Just open this page and use it.
