Classroom Timer
A full-screen countdown timer built for the classroom — set the minutes, hit start, and keep the whole room on track. Runs on your device — nothing is uploaded, nothing is stored.
Best used in fullscreen so the whole class can see the countdown.
Classroom Timer is a fullscreen-friendly countdown built for the front of a room — timing a test, a silent reading period, a group activity, or a transition between subjects, where everyone needs to see the remaining time at a glance from across the room.
Set the minutes, hit start, and go fullscreen so the numbers fill the projector or screen. It's the same countdown engine as the general Timer tool, just opened straight into a countdown preset with a nudge toward fullscreen mode, so you don't have to dig through settings before class starts. A sound plays when time runs out, so you don't have to keep glancing at the screen.
It runs entirely in your browser with no account and no ads — open the page, set the time, and project it.
