Half an Hour, Put to Work
- Daily exercise — Australia's physical activity guidelines recommend adults build up 2.5 to 5 hours of moderate activity each week, ideally spread across most days. That's roughly 30 minutes a day — one timer.
- A solid study block — thirty minutes is enough to work through a topic properly, then take a 5-minute break before the next one.
- Cooking and baking — cakes, casseroles and slow-simmering sauces often need 30 minutes or more; a timer on your screen saves checking the oven every five.
- Screen-time limits — a clear, impersonal countdown makes "time's up" much easier for kids to accept.
- Timeboxed meetings — half-hour meetings that actually finish on time.
Thirty Minutes or 25?
If you're using the Pomodoro Method, 25 minutes plus a 5-minute break fits neatly into each half hour — try the 25 minute timer. For deeper work, go longer with the 1 hour timer.
For the Kitchen and the Desk
If you'd rather not keep a browser tab open, a kitchen timer or a visual timer with a 60-minute dial covers everything from dinner to homework.
30 Minute Timer — FAQ
Will the timer keep running if I switch tabs?
Yes. The countdown is based on the clock, not the tab, so it stays accurate in the background and the alarm is scheduled to sound on time. The time left also shows in the browser tab title.
Can I use it for kids' screen time?
Yes. A visible countdown makes the limit clear and impersonal — the timer ends the session, not you — which tends to reduce arguments. Full screen mode makes it easy to see from across the room.
Is it free?
Completely free, with no sign-up, no app and no ads.
