# Clocks & Timers

A countdown timer counts down from a set time, while a stopwatch counts up from zero, often with lap times. Alarms, interval timers for workouts, focus timers for study and full-screen clocks build on the same two ideas. Browsers may slow timers in background tabs, so keep the tab open and visible when precise timing matters.
