In active development
The swimming coach's stopwatch. In training, swimmers leave the wall on staggered 5–10 second intervals — the first in every lane together, then the next, and the next — and one wall clock can't time them all. Poolside gives every swimmer their own accurate time, from one phone in the coach's hand.
Tap Start as each group leaves the wall — the 1st swimmer in every lane together, then the 2nd, then the 3rd. The clock starts with the first group.
Tap a lane's Stop as its swimmer finishes. Their own elapsed time — measured from their start, to the hundredth — freezes in place.
No mental arithmetic at the end of the rep. Every swimmer's time is on screen, ready to read out — then one tap clears the board for the next rep.
