About this tool
Half an hour is one of the most useful lengths of time: a workout, a study session, a meeting, a child’s screen time, a cake in the oven or the free period in a car park. The World Health Organization advises adults to get at least 150 minutes of moderate activity a week, which is 30 minutes on five days.
This 30 minute timer is set as soon as the page opens. It counts down to a fixed end time, so it stays exact in a background tab, and the sound is scheduled the moment you press Start. Turn on "Keep the screen on" if you use it on a phone or tablet.
