About the Lap Stopwatch
The lap stopwatch is built around one question: not just how long did the whole effort take, but how long did each piece take. Every press of the Lap key writes a row with two numbers - the split for that segment and the cumulative total - which is exactly how track coaches, swim timers, and interval athletes think. Total time can look fine while hiding a collapse: a runner covering four laps might hit the goal overall yet fade badly on lap three, and only the split list reveals it. This page keeps the growing lap list visible beside the live digits, newest on top, so you can call out the last split without scrolling mid-set.
How to use it
- Decide the exact lap trigger point before the session begins.
- Start the stopwatch at the opening cue with Start or Space.
- Press Lap or L at the trigger point on every repetition.
- Watch split and total columns build in the visible list.
- Stop, then copy the lap list before resetting the session.
Good to know
The stopwatch counts while this tab is open. A slept tab can pause or jump. For a race result you may need to keep the phone unlocked in your hand.
