How to use it

Press Start. The bar fills as time runs out; Pause and Resume anytime.
Listen for the alarm. A clear beep repeats until you reset — keep your sound on.
Why a browser timer?
No app to install, nothing to sign into, and it works the same on a phone, a school Chromebook or a work laptop. Because it measures real elapsed time rather than counting screen refreshes, it stays accurate even if you switch tabs to check a recipe or an exercise. The stopwatch keeps hundredth-of-a-second laps for workouts, cooking stages and classroom activities.
