How accurate is this online stopwatch?
Accurate to about 16 milliseconds (one frame at 60fps). For mission-critical timing, use dedicated hardware.

No — closing the tab pauses the stopwatch. We don't use background timers (battery-friendly).
Can I export lap times?
Copy-paste from the screen. Full export is planned for a future update.
