Countdown timer

A big, clear countdown timer for lessons, tasks, games and streams. Pick a preset or set a custom time, and watch a giant, readable clock count down — with an optional beep when it hits zero. There’s a stopwatch mode too.

How to use it

Choose a preset (1, 3, 5, 10, 15 minutes) or type a custom time.
Press Start — the clock is large enough to read from across a room.
Pause, resume or reset at any time; switch to Stopwatch to count up instead.
Go fullscreen for a distraction-free display on a projector or second screen.

Who it's for

Teachers: time a starter, a task or a test with a clock the whole class can see from the back.
Streamers: run a “starting soon” or break countdown, in fullscreen or on a green-screen background for OBS.
Anyone: time a workout, a presentation or a game round without hunting for your phone.

FAQ

Is the timer accurate?

Yes — it’s timestamp-based, so it stays accurate even if the tab is in the background, with no drift.

Can the class see it from a distance?

Yes. The clock is deliberately huge, and fullscreen mode makes it fill the screen for projectors.

Does it beep when it finishes?

It can — there’s an optional end beep you can switch on or off.

Is there a stopwatch too?

Yes — switch to Stopwatch mode to count up from zero.

Do I need to install anything?

No. It runs in your browser, free and ad-free, and works offline after the first visit.
