Laps and Precision
Press Lap while the stopwatch is running to record a split without stopping the clock. Laps are listed below the display with the total elapsed time at each point.
The stopwatch is driven by a high-resolution timestamp loop instead of a simple interval, so it stays accurate even if your device throttles background tabs.
