Classroom visual timer

A time disk you can read from the back of the room

A visual timer shows time as a shape that shrinks, not as a clock you have to decode. This page opens on a thick remaining disk: most of the time it stays calm terracotta, the last fifth turns amber, and the last tenth turns red so the whole stage signals “almost done.”

Switch to a glass ring or a row of blocks without resetting the countdown. Hide the digits when the class should watch the color. Fullscreen keeps the screen awake for a projector. Sound stays off until you ask for a soft chime.

  1. 01

    Pick a length

    Tap a classroom activity, a length from 30 seconds to 25 minutes, or drag the disk. Five minutes is the starting length.

  2. 02

    Choose what the room sees

    Disk is the classroom default. Ring is a thin glass arc. Blocks drop away one by one for younger children. Turn numbers off if the shape should do the talking.

  3. 03

    Start, extend, or go quiet

    Start when the activity begins. Add one minute while it runs if the room needs longer. The last ten seconds say “almost done.” At zero the stage says “time’s up” and pulses once. A tick and a chime play only if sound is on.

Why this is not another pie chart

Most online visual timers are a flat slice on a white page. This one is a stage: a physical disk with a hub, quarter marks, and a color that travels with the time. The same countdown can become a ring or a row of blocks, and the page can hide every digit.

Embed the visual timer

Copy an iframe for a class page. The clock runs in the visitor’s browser.

What this visual timer can do

  • Remaining disk A thick wedge shrinks clockwise from a full circle, with a hub for the time and marks at each quarter.
  • Three faces, one clock Disk, glass ring, or twelve blocks. Changing face does not reset the time left.
  • Numbers you can hide Leave the clock in the hub, or hide it so the room watches color instead of counting down the digits.
  • Fullscreen for class Fill the screen and keep it awake while the timer runs, so a projector does not dim mid-activity. Length controls step aside so the shape can fill the screen.
  • Quiet ending Sound is off by default. The finish is an empty disk and one slow pulse, with an optional soft chime.
  • Private on this device The last length, face, digits, and sound stay in this browser. Nothing is uploaded and no account is required.

Visual timer FAQ

Classroom disk, hiding numbers, fullscreen, and the quiet finish.

What is a visual timer?
A visual timer shows time remaining as a shrinking shape. People read the color and the size from across a room, which helps classrooms, young children, and anyone who loses track of a numeric countdown.
How is this different from the online timer?
The online timer is a numeric countdown. This page is built around the disk, the ring, and the blocks, with the option to hide the numbers entirely.
Can I hide the numbers?
Yes. Hide numbers leaves the shape and the color, and keeps the time available to screen readers.
Does changing the face reset the timer?
No. Disk, ring, and blocks are three views of the same countdown.
When does the color change?
The shape stays terracotta for most of the time, turns amber in the last 20 percent, and turns red in the last 10 percent. The last ten seconds also say “almost done.” At zero the stage says “time’s up” and pulses once.
Will it make a sound?
Not unless you turn sound on. The default finish is visual only: an empty disk, the words “time’s up,” and a soft pulse. With sound on, a quiet tick marks each of the last ten seconds, then a short two-note chime.
Can I add time while it is running?
Yes. +1 min adds sixty seconds to the time left, up to 60 minutes.
Does fullscreen keep the screen awake?
The page requests a wake lock while the timer is running or fullscreen is on, so a projector or laptop is less likely to sleep.
Can I share a setup?
Copy link puts the length, face, numbers, and sound into the URL. Opening that link restores the same setup on this device’s browser.
Is an account required?
No. The timer runs in the browser and stores the last setup on this device only.
