About this timer
About the length of a school class period or a gym session. It's also a common baking time for pasta bakes and gratins.
Close to an hour without committing to one, which suits deep work sessions, laundry cycles, exam practice, and slow cooking. Leave the tab in the background and the alarm will still fire at the right moment, because the countdown is anchored to a clock time rather than to a ticking counter.
