A 30 minute timer for classes, meetings, and workouts

Half an hour is the standard length for a school period, a routine meeting, or a full workout session. It's long enough to matter if it runs over, which makes a visible, reliable countdown genuinely useful rather than just a nice-to-have. The timer opens set to 30 minutes.

Running this for a group

For a class or meeting, switch to fullscreen mode and the display scales up to fill the screen — readable from across a classroom or on a shared-screen call. Teachers timing activities may prefer the dedicated classroom timer page, which defaults to the large display automatically.
