Classroom timer for teachers
Big, readable digits designed for classroom whiteboards. Tickline's classroom timer changes colour in the last minute so students know exactly how long they have — 5 min quick task, 15 min group work, 45 min exam block, all one tap away.
Frequently asked questions
Can I mirror this on a projector?
Yes — Fullscreen mode fills the display and the digits stay readable from the back of the room.
Does the alarm keep ringing?
