Timer

Type a duration into the field and press Enter. The field understands “5”, “5:30”, “90s”, “1h 15m” and “until 14:30”. The buttons below start a fixed duration with one click. Next to them are the durations you used last.

When time is up, a tone sounds and the timer keeps counting into the minus. That way the group can see how far over it is. Full screen leaves only the digits and the buttons, for a projector. If you like, the browser also shows a notification.

For slides, “Small window” opens the timer on its own, with no menu and no text. In Chrome and Edge this window stays above all others. Other browsers open an ordinary small window that can fall behind others. Both windows show the same timer.

A link carries the duration. ?⁠t=10m opens a ten-minute timer, and ?⁠t=10m&⁠start=1 starts it straight away. The “Copy link” button builds the link for the time you have set.

The timer runs entirely in your browser. Under the key nz-timer it remembers the running timer, the stopwatch, the durations you used last and whether the sound is on. That way it survives an accidental reload. None of it goes to a server.

One timer runs at a time, not several side by side. There are no intervals as in Pomodoro, no alarm for a time of day and no account. What you set stays on this device.

The tone needs an open tab. If you close it, the time still runs on and is correct when you next open the page, but the tone is missed. On a phone the screen stays on while the timer runs. If you lock it anyway, the tone may not sound.
