Timer & stopwatch

The Timer & stopwatch is two tools in one panel. Set minutes and seconds or tap 5, 10 or 25 minutes and start: the tab title counts down with you, and at zero the page flashes and beeps; the stopwatch runs with laps you can copy as text.

Yes. The page keeps the moment it started and computes the rest from the clock, so a tab the browser slowed down still shows the right time when you come back. The sound plays only while the tab exists.

The panel flashes and the browser plays three short beeps of its own — no audio file — as long as the tab is still open. If you have already allowed notifications for this site, a notification comes too; the page never asks for that permission.

5, 10 and 25 minutes as chips — 25 is the classic pomodoro — or any minutes and seconds in the fields.

One line per lap: the lap number, its split and the running total, separated by tabs, so it pastes into a spreadsheet as three columns.

Yes. Pause stops the countdown, Resume picks it up, and Reset takes it back to the time you set.
