30 Minute Timer
A thirty-minute countdown, pre-set and ready. Plays an alarm at zero — ideal for cooking, workouts, and half-hour focus sessions.
What is a 30 Minute Timer?
A 30 minute timer counts down half an hour — 1,800 seconds — and sounds an alarm at zero. This one is pre-set to thirty minutes and starts with a single tap. Half an hour suits roasting and baking steps, a solid workout, or a deep-work block on one task. It times accurately using your browser's Performance API, keeps running in background tabs, and requires no account or download.
