    Classroom pack

    The same timer, packaged for class

    This page loads a 45-minute classroom countdown and lists ready embed snippets for a period, an exam hour, and a five-minute transition. Share links include campaign tags so you can tell which template traveled.

    You do not need a new product. Fullscreen the stage for the projector, or paste an iframe on Google Sites / an LMS. Timing never leaves the visitor’s browser. For a dedicated period URL, use the classroom timer page; for tests, the exam timer page.

    1. 01

      Start 45:00 or copy an embed

      Press Start to run this period on the board. Or copy an iframe below for a class page. Share links open the matching timer landing with UTM so you can see what was forwarded.

    2. 02

      Start the countdown

      Press Start or Space. Progress updates on a circular dial, and the face shows when the timer ends. Pause anytime, add +1 min, queue another timer, or go fullscreen / sleep for a distraction-free display. The tab title shows remaining time while you work elsewhere.

    3. 03

      Hear the alert & keep going

      When time is up, stop the alarm with one tap. Start the next queued timer, review local history, export CSV, or copy a shareable link. A refresh restores an in-progress countdown on this device.

    Why a teacher page instead of another app

    School filters already allow a browser tab. Embeds keep the countdown on a class site you already maintain. There is no student login to provision and no data to store in a vendor cloud.

    Embed recipes for teachers

    Paste an iframe on a class site or LMS. Timing runs in the student’s browser — no account, no roster. Share links include campaign tags so you can see which template was copied.

    • Classroom period (45:00)

      Large digits for a projector or spare monitor. Fullscreen the class page when you need the whole board.

      Share this timer

    • Exam block (60:00)

      A silent hour on a shared display. Use sleep mode on the full timer page if chrome is distracting.

      Share this timer

    • Transition bell (5:00)

      A short station or cleanup countdown. Pair with the 5 minute timer page if you want a bookmark, not an embed.

    What you get

    • Presets & quick lengths Jump to common seconds, minutes, and hours, or named timers like study and classroom. The Countdown pane still offers weekdays, times of day, and a custom datetime — holiday countdowns are on the Online Countdown tool.
    • Background-tab accuracy Countdown uses deadline math so it stays correct when the browser throttles hidden tabs.
    • Sounds, notifications & wake lock Choose alert sounds and ring length, get a desktop notification when finished, and keep the screen awake while running.
    • Fullscreen & sleep mode Go fullscreen for a large dial display, or sleep to dim the whole page so only the countdown stays visible.
    • Up-next queue While a timer is running, tap presets to queue up to three countdowns and start the next when you are ready.
    • Embed widget Drop a compact countdown on your site with custom colors, size, skin, and default duration.

    Frequently asked questions

    Setting the dial, presets, alerts, and embeds — quick answers.

    Do I need student accounts to use this?
    No. The timer and embeds run in the browser. Nothing is saved to a school roster on our side.
    Can I remove branding from the embed?
    The public embed includes a small logo. Use the embed builder on the timer to toggle logo and colors. Paid unbranded embeds are not part of this pack.
    Which link should I send a substitute?
    Send the classroom timer page (45:00) or a share link from the recipes below. They can Start without creating an account.
    Is the teacher pack a different timer?
    No. It is the same online timer with a 45:00 default, extra copy, and copy-paste embed/share templates aimed at education.
