Help for Classroom timer

Classroom timer

A visual classroom timer with a shrinking disc, exact remaining time, large controls and optional sound.

How to use it

  • Choose a preset or enter minutes and seconds, then press Start. Pause, resume or reset. A full disc represents your chosen duration and shrinks to zero.
  • 1 second to 180 minutes.
  • Press F to enter fullscreen. The controls disappear after three seconds of inactivity. Move your mouse or tap to show them again.

Good to know

Sound is off by default. Turn it on and test it if you want an end signal.

For timer sounds, keep this tab open and your device awake. Press Start to enable audio; sleeping devices and suspended tabs may delay or silence the alert.

Keep the screen awake while this tab is visible.

The recipient opens the link with your settings. A running timer keeps its original end time. A paused timer opens with the time remaining when you shared it.

A shared link captures a moment: later changes are not synchronised. Event names and any other details you enter are included in the link.

Share using your device’s share menu or copy the link. If copying fails, select and copy the link shown on screen.
