About this timer
A standard lesson or workout length, and a common rise time for bread dough. Dough is ready when it has roughly doubled, so let the timer remind you to check.
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.
Need a different length? Set a custom timer in hours, minutes and seconds, or pick one of the presets below.
