Our stopwatch provides two key pieces of information when you record a lap, and understanding the difference is key:
This is the time it took to complete a specific segment, measured from the moment you last pressed the "Lap" button. It is ideal for measuring the duration of individual intervals, like one lap around a track.
This is the total running time from the moment you first clicked "Start" until the moment you clicked "Lap". It shows your overall progress at the end of each segment. For example, after the second lap, it will show the combined time of Lap 1 and Lap 2.
