You are timing three rounds of a workout and need lap splits without fumbling for your phone.
Actions
Start → Lap (1:58.4) → Lap (2:05.1) → Lap (1:51.7) → Stop
Recorded session
Lap 1 01:58.40 Lap 2 02:05.10 (slowest) Lap 3 01:51.70 (fastest) Total 05:55.20
The stopwatch records each lap as an independent split while keeping a running total, so you see both per-segment pace and elapsed time at once. Elapsed time is computed from wall-clock timestamps captured at start and at each lap, not by incrementing a counter every tick, so the splits stay accurate even if the timer interval fires unevenly.
