How it works

  1. 1

    Set the time

    Type the minutes for the task, or tap a preset like 5 or 10 minutes. The digits fill the screen.

  2. 2

    Show it to the room

    Start the countdown and put it on the projector or board. Everyone can read the time from anywhere in the room.

  3. 3

    Wrap up on the chime

    The colour shifts as time runs low, then a clear chime marks the end so the class knows to stop.

Great for

  • ✓ Timed tasks and group activities
  • ✓ Tests, quizzes and exam practice
  • ✓ Transitions and tidy-up time
  • ✓ Brain breaks and quiet reading

Frequently asked questions

Can the whole class see it from the back?
Yes. The digits scale to fill the screen, so on a projector or large display they stay readable from across the room. The colour also changes as time runs out, giving a visual cue even to anyone who is not watching the exact numbers.
Will it work on the classroom projector or smartboard?
Yes. It runs in any modern browser, so it works on an interactive whiteboard, a projector connected to a laptop, or a classroom display. Once the page has loaded it keeps running even if the school connection drops.
Is there a sound when time is up?
Yes, a clear chime plays at zero, with the screen flashing as a backup for a noisy room or muted speakers. Because browsers need one tap before audio, starting the timer unlocks the sound.
Does it work offline?
Yes. Once the page has loaded it keeps running with no connection, because the whole tool runs in your browser. You can install it to your home screen and open it like an app.
Do I need an account, and is anything tracked?
No account and no sign-up. The tool runs on your own device, so there is nothing to log in to and your settings stay on your machine. No popups, no clutter.
