About countdown timer / stopwatch
A countdown timer counts down to zero, and a stopwatch counts up. Both run in your browser, so you can use them for cooking, workouts, exams and presentations.
Tips
- Keep the tab open and the screen awake while the timer runs.
- Turn the sound on so you notice when time is up.
- A countdown that must be accurate for a long period should also be set on a phone alarm.
A worked example
For a 10-minute presentation practice, set the timer to 10:00 and start it. The stopwatch mode is better for timing something of unknown length, such as a workout set or a lap.
Tips
- Keep the browser tab open, because some browsers slow timers in background tabs.
- Use a separate alarm for anything important.
- Turn the volume up so you hear the end signal.
