Classroom timer

A big, calm timer for the whole class

Project it on the board so everyone can see how much time is left. The disc works even for students who cannot read a clock yet.

Focus is better together.

Share one timer. Everyone with the link can control it. No sign-up.

Drag the disc to set up to 60 minutes

Ready when you are

Keep this tab open. Sleeping devices and suspended background tabs may miss the chime.

Shortcuts: Space start/pause · + add a minute · F fullscreen

In class

  • Press F for fullscreen on the projector, or use Focus view.
  • Hide the numbers for younger students; the shrinking disc is enough.
  • Pick a color, then use + to add time without stopping the activity.
  • A gentle chime and color change mark the end; there is no alarm.

Sharing with students

Create a room to show the same timer on student devices. Anyone with the link can control the timer, so only share it where that is fine.
