What is a Stopwatch?
A stopwatch is a tool that measures elapsed time with millisecond precision. It is useful for sports, studying, cooking, gaming, and any situation where you need to track time accurately.
The Toolzi stopwatch uses Date.now() for accurate timekeeping even when the tab is in the background. You can copy lap records as text for documentation.
How to Use
- Press Start (or Space) to begin timing.
- Press Lap (or L) during timing to record a split time.
- Press Stop (or Space) to pause, then Resume to continue.
- Press Reset (or R) to clear the timer and all laps.
