Questions About This Duration

Can a browser delay the countdown display?
Rather than counting ticks, the timer saves a finish time from your device clock and watches for it. Even if your browser throttles a background tab, the remaining time corrects itself the moment you look back. Keep the tab open and test sound because devices can suppress background audio.
What happens if I reload the page?
Your timer is saved in your browser, so reloading picks it up right where it left off rather than starting over.
What happens to a long timer in a background tab?
The display recalculates from the saved finish time when the browser runs the page again. Background audio may still be delayed or suppressed.
Can I change or mute the alarm sound?
Yes. Use the sound toggle to mute the alarm at any time. The alert is generated in your browser, so nothing is downloaded. An already loaded page can continue without a connection, subject to browser audio restrictions.
Is there an app to download or an account to make?
Neither. Everything runs on this page in your browser, so there is nothing to install and no sign-up. Open it on any phone, tablet or computer and it behaves the same way.
Is my timer private?
Completely. The timer runs on your device and your settings are stored only in your own browser. Nothing about your countdowns is sent to a server or shared.
