MAKE IT YOURS

Plan the lesson once. Use it again.

Choose a quick timer or build a sequence such as Warm-up, Group work and Exit ticket. Give each activity a label and duration. Save the routine on this device, then start and open fullscreen.

Students see the current activity, remaining time and visual progress. Teachers can pause, skip a stage or return to settings using clearly labeled controls. Quiet mode silences all audio; optional spoken reminders do not require a microphone.

Questions about classroom timer

Can I reuse a lesson sequence?

Yes. Name and save the routine locally, then load it next time. Export a routine file to keep a backup or import it on another device.

Can students see only the countdown?

Fullscreen removes page navigation and setup panels, leaving the activity, timer, progress and essential timing controls. Press Escape or Exit fullscreen to return.

What happens if I close the page?

Recent timer sessions and preferences are stored in this browser when storage is available. Recovery uses your device’s clock. Private browsing, cleared storage and device sleep can affect recovery. Keep the page open and test audio before relying on alerts.
