For cooking, workouts and focused work
Egg timer, plank challenge, presentation or the Pomodoro technique (25 minutes of work, then a break): a browser timer is quicker than any app. Time left is also shown in the tab title.
The stopwatch measures to a hundredth of a second and stores any number of laps with split and total times.
