Great work, everyone.
A timer built for the front of the room
Students can read this timer from the back row. The disc shrinks as time runs out and changes from green to yellow to red, so even children who can't read a clock yet know how much time is left. The words on the board say what everyone should be doing.
- Eight classroom activities, one tap each: silent reading, partner talk, clean up, brain break, writing, group work, line up and test time.
- Any length from 10 seconds to 3 hours, with chips for 1 to 60 minutes and boxes for exact minutes and seconds.
- Station rotations for centers: 2 to 10 stations, a switch time of up to 5 minutes and a purple Switch! screen.
- Sounds that help: a chime at 1 minute left, 3-2-1 blips and a cheerful end chime with confetti. Mute them all with the speaker button.
- Show to class hides the controls and fills the screen. The screen stays awake while the timer runs.
- Light and dark themes, and a Copy link button that saves your set-up for tomorrow or for a colleague.

Questions teachers ask
Is this classroom timer free?
Yes. There's no sign-up, no download and nothing to install. Open the page on the computer connected to your projector or board and press Start.
How do I show the timer on my projector or smartboard?
Press Show to class at the top. The page goes full screen and hides every control, leaving the words, the disc and the digits. Tap the board or press the space bar to pause, and press Esc or Exit to get the controls back.
Does the timer keep time if I switch to my slides?
Yes. It works out the time left from the clock rather than counting ticks, so it stays accurate in a background tab, and the chime still plays when time is up.
What do the colours mean?
Green means more than half the time is left, yellow means less than half, and red means the last 20 percent. Station switch time shows in purple. You can turn colour changes off.
Can I run station rotations?
Turn on Station rotations, choose 2 to 10 stations and a switch time from 0 seconds to 5 minutes. One Start runs every station, with a purple Switch! screen in between.
Why is there no sound until I press something?
Browsers only allow a page to play sound after you interact with it. Pressing Start (or the speaker button) turns sound on for the rest of the session.
