Three timers in one: a stopwatch, a countdown with quick presets, and a Pomodoro with adjustable work/break cycles and a beep when time is up.
Work in focused intervals (traditionally 25 minutes) separated by short breaks to sustain concentration.
Timing uses absolute timestamps, so elapsed time stays accurate even if the tab is throttled.
Yes — a short tone plays via the Web Audio API when a countdown or Pomodoro phase finishes.
