What this classroom timer does

This free classroom timer gives teachers a large projected countdown, preset activity lengths, custom minutes and seconds, and a visual progress bar. It is designed for classroom screens instead of generic timer tabs.

How to use the timer

  1. Choose a preset or enter custom minutes and seconds.
  2. Add an optional activity label such as Warm-up or Group work.
  3. Select Start and keep the countdown visible for the class.
  4. Use Pause, Resume, or Reset as the activity changes.

Built for projected classroom activities

The timer uses a large remaining-time display and a visual progress bar so students can quickly see how much time is left. The progress bar supports the countdown, but the numeric time remains the main source of information.

Privacy: no student names needed

This teacher timer does not need a class list, account, database, analytics, ads, or external API. The optional activity label stays in the page only and is not saved, uploaded, or placed in the URL. Use activity labels, not student names, school IDs, classroom identifiers, teacher names, or sensitive details. See the privacy notes for the current no-upload, no-storage scope.

FAQ

Can I use this as an online classroom timer?

Yes. The page is built for quick classroom countdowns with preset times, custom durations, large display text, and visual progress.

Does the classroom timer play a sound?

No. The MVP uses a visual completed state first so there is no surprise audio in class. Sound can be reviewed separately later.

Is the activity label saved?

No. The optional activity label is only displayed on the current page. It is not stored, uploaded, sent to analytics, or added to the URL.

What is the maximum custom timer?

Custom durations can be set up to 99 minutes and 59 seconds.
