Timer, stopwatch and clock for the classroom screen

Three tools on one page: a countdown timer, a stopwatch and the time of day. The digits are large enough to read from the back of the room, so the page can stay on the projector for a whole lesson.

A timer for a task

Set the time either from the presets (1, 5, 10 or 15 minutes) or enter an exact duration in hours, minutes and seconds. The timer starts, pauses and resets with a single tap. A timed task becomes visible to everyone at once — nobody has to ask how much time is left.

Stopwatch and time of day

The stopwatch counts up and suits measuring an experiment, a presentation or an exercise. The clock view simply shows the current time in large type — useful when the room has no wall clock, or when you want everyone watching the same clock.

Works without an account

The page opens straight away, with no sign-in, no install and no ads. It runs in the browser — computer, tablet and phone — and follows light or dark mode, so a dimmed room does not get a glaring screen.

Frequently asked questions

How do I put a big timer on the classroom screen?

Open the timer tab, pick a preset or enter your own duration and press Start. Show the page on the projector or display — the digits stay readable from the back of the room.

Does the timer signal when it runs out?

Yes, the end of the countdown is shown on screen. In a quiet room you can rely on the visual signal alone.

Do I need to install anything or create an account?

No. The tool runs directly in the browser, is free and requires no account.

Can I use the timer on a phone?

Yes. The layout adapts to the screen width and works on phones, tablets and computers alike.
