Designed for the job

A timer that behaves predictably

Correct after tab switching

The countdown uses an absolute end time, so delayed browser intervals do not add extra seconds.

Clear from across a room

Fullscreen mode, a high-contrast display, and a stable progress ring keep the remaining time easy to read.

Useful controls

Pause and resume without losing time, test the alarm before starting, and use keyboard shortcuts when your hands are busy.

Private by default

The timer runs locally in your browser. There is no account, timer history, or personal profile.

For teachers and groups

Classroom timers
