Stopwatch
Start and pause with the space bar, record laps, go full screen.
Keyboard shortcuts
Space: start and pause. L: lap. R: reset. F: full screen.
How it works
Time is derived from the browser clock, so it stays accurate when the tab is in the background. The fastest lap gets an accent border, the slowest a dashed one. Nothing is sent to a server.
Frequently asked questions
Does the stopwatch keep running in a background tab?
Yes. It measures the difference between the start moment and now rather than counting ticks, so it shows the right value when you return.
How do I go full screen?
The full screen button or the F key. Leave with the same button or Esc.
Are laps saved?
They are cleared when the page reloads; nothing is stored.
