Classroom Timer
Project a clear countdown for any classroom activity. Set a duration, add an activity label, choose from editable presets like independent reading or group work, and enable an optional warning threshold that changes the display color as time runs low. Sound is muted by default for classroom use. Full-screen mode fills the screen for visibility at the back of the room.
