Timer and stopwatch.

The countdown takes hours, minutes and seconds or a preset from one minute to an hour, counts to zero and beeps three times if you let it. The stopwatch counts up to hundredths of a second and keeps laps with their splits.

Three short tones from the browser's own oscillator, no sound file and no request. Untick Beep when done for a silent end; the face and the tab title still show it.

Browsers slow down timers in a tab you have left, so the timer measures elapsed time against the clock rather than counting ticks: when you come back, the face is right. The tab's title carries the remaining time so you can see it from another tab.

Pomodoro is 25 minutes of work and a short break; the 25 min preset is there for it. Set any length up to 99 hours with the fields.

Pick a preset or type a duration, press Start; Pause holds it and Reset clears it. Full screen puts the face alone on the screen for a room or a desk.

Switch the Mode to Stopwatch, press Start, and Lap while it runs; each lap is listed with its split from the one before and the total.
