Classroom settings
Set the timer label and classroom sound cues before starting.
Classroom Timer (Fullscreen Countdown)
Big, readable countdown for smartboards and projectors with presets, custom labels, sound cues, and keyboard shortcuts.
Run a visible classroom countdown
Choose a preset or enter a custom number of minutes. The title field changes the label shown with the timer. During a run, -1 min, +1 min, and +5 min adjust the remaining time without rebuilding the setup.
For a 12-minute activity, enter 12 and set the title to Group work. Start the timer, then add five minutes if the activity is extended. The display changes to reflect the new deadline.
Display behavior
Pause holds the current remainder. Reset returns to the selected class duration. Fullscreen keeps the label and large time visible. The page has no student accounts, remote controls, or durable class history. Device sleep can delay both the display and any completion sound.
