About the online stopwatch
A simple, accurate stopwatch for the classroom, gym or home. It counts to the hundredth of a second, records laps, and goes fullscreen for the projector. Like our timers, it runs from the system clock, so it stays accurate in a background tab.
Ways to use it
- PE races and fitness tests.
- Science experiments and reaction-time tests.
- Timing speeches, presentations and reading fluency.
