Frequently asked questions
Does it keep running if I switch tabs?
Yes — timing is based on the clock, not the screen refresh, so it stays accurate in the background. Keep this tab open.
How precise is it?
It displays hundredths of a second and recalculates from the system clock 30+ times per second.
Is there a maximum time?
It counts minutes past 59 (75:20.00 style) — no practical limit for everyday timing.
