Classroom Timer
Huge digits that the back row can read. Tap a time, go full screen and a bell rings when the activity is over.
How to use it
- Tap a preset from 1 to 30 minutes (or set a custom time).
- Press Full screen (or F) to fill the projector or TV.
- Start the timer. The digits change colour in the last minute and a bell rings at zero.
Good for
Group activities
Give every table the same visible deadline.
Tests and quizzes
Students can glance up instead of asking how long is left.
Transitions
A 1–3 minute timer makes tidy-up and room changes predictable.
Frequently asked questions
How do I make the timer fill the screen?
Press the Full screen button or the F key. On iPhone, where browsers cannot enter true full screen, the timer expands to fill the browser window instead.
Will the bell be loud enough?
The bell plays through your computer's audio output, so connect speakers or the projector's audio and set the volume before class.
Why are there no ads on the timer itself?
The classroom view is meant to be shown to a room. Ads only appear below the tool on the normal page, never on the timer or in full screen.
