Feel your pace. Never look.
Haptic pace alerts for endurance swimmers, on Apple Watch.
Set a target pace per 50, 100, or 200 meters. Every time you complete that distance, SwimDelta checks your split against it.
Fall behind and your wrist gets one firm tap, with a red screen showing exactly how many seconds that split lost. Back on pace? Green, and silence.
Stop at the wall and the set closes itself — rest timer, set summary. Push off and the next set starts. Water Lock stays on the whole swim.
Split-accurate lap detection in the pool (25 m, 50 m, 25 yd). GPS pacing with noise-filtered alerts in open water.
Set-by-set breakdowns, split-by-split green/red detail, rest times, and pace trends across weeks.
Full Apple Health integration — every workout closes your rings and appears in Fitness with heart rate and stroke data.
