Classroom Timer

A big, simple countdown timer for the classroom. Set minutes and seconds or tap a preset, project it on your board, and hear the beep when time is up.

Set your timer

05:00
Ready.

⏱️ Big readable display

Oversized digits scale to any screen — project it on your smartboard and the whole class can see the time from the back row.

🔔 Alarm beep

A clear triple beep sounds when time runs out. No audio files to load, and it works even if the tab is in the background.

📑 Background-tab friendly

The browser tab title shows the remaining time, so you can keep working in another tab and still glance at the countdown.

How to use the classroom timer

  1. Set the time — type minutes and seconds, or tap a quick preset (1, 5, 10, or 15 minutes).
  2. Press Start — the big display counts down and the progress bar drains. Pause any time and resume exactly where you left off.
  3. Hear the beep — when time is up you'll hear a triple beep and see "Time's up!" (make sure the tab isn't muted).
  4. Project it — press F11 for fullscreen on your classroom computer or smartboard for maximum visibility.

Quick answers

How do I set a 5-minute classroom timer?

Click the 5 min preset (or type 5 in the Minutes field), then press Start. The big display counts down from 05:00 and plays a triple beep when time is up.

Will the timer beep if the tab is in the background?

Yes. The alarm is generated in the browser itself, so it plays even when the tab isn't visible — and the tab title keeps showing the remaining time, so you can monitor it while working elsewhere.

Can I pause and resume the timer?

Yes. Pause freezes the countdown exactly where it is, and Start resumes from that point. Reset returns the timer to the time you set.

Frequently asked questions

Is the classroom timer free?

Yes — completely free, no account, no limits. We plan to keep it free supported by advertising.

Do I need to install anything?

No. It runs in any modern browser on a computer, tablet, or smartboard. Just make sure the tab isn't muted so you can hear the alarm.

Why is there no sound when time is up?

Browsers block sound until you've interacted with the page — pressing Start once unlocks it. Also check the tab isn't muted and your device volume is up.

What's the longest timer I can set?

Up to 999 minutes. The quick presets cover the most common classroom needs: 1, 5, 10, and 15 minutes.

Does it work on a smartboard?

Yes. The display scales to any screen size — open the page on your classroom computer or smartboard browser and press F11 for fullscreen.
