About this timer
Plank holds, stretching intervals, or one quarter of your mouth when brushing: dentists commonly recommend two minutes in total. Also a comfortable margin for handwashing, which should last at least 20 seconds.
Short countdowns like this are usually about precision rather than patience: plank holds, rinse times, speed rounds, or anything where watching a clock would be a distraction. The alarm is the point, so keep the sound on and the tab open in the background.
