Acerca de Online Stopwatch
Time workouts, cooking, study sessions, experiments or customer calls with a stopwatch that records to a hundredth of a second. The lap function logs splits without stopping the clock, and the elapsed time is driven by your device's high-resolution timer — so it stays accurate even if your screen throttles. Big, glanceable digits make it readable from across the room or the running track.
