Round timer

Give every player the same time. Choose a round length and press Start, and the ring counts down to zero, with a chime when time is up.

Tips

The timer measures real elapsed time, so the round ends on schedule even when the tab is in the background.
Where your browser supports it, the screen stays awake while the timer runs.
Your last round length and sound setting are remembered on this device only.

Questions

How accurate is the timer?

It measures real elapsed time with the browser's performance clock rather than counting interval ticks. In a background tab the chime can arrive a moment late, but the timer checks the time again as soon as the tab is shown.

Does the chime need permission?

No. Your browser generates the two-tone chime with the Web Audio API after you press Start. Nothing is downloaded or sent, and the Sound chip turns it off.

Does it work offline?

Once Paperoom is installed or the page has been saved for offline use, the timer runs without a connection.
