Feel your pace. Never look.
Haptic pace alerts for endurance swimmers, on Apple Watch.
Set a target pace per 50, 100, or 200 metres. Every time you complete that distance, SwimDelta checks your split against it. A set that ends short is still scored, pro-rata.
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.
Sets close and reopen on their own as you stop and push off. Water Lock is on from the first length to the last. To finish: unlock the crown and swipe.
Delta, total distance, elapsed time, pace, heart rate, and the time of day — so you can leave on the clock without hunting for a second screen.
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.
No account. No cloud. No ads. No tracking. Everything lives in Apple Health on your devices. App Store privacy label: Data Not Collected.

Apple Watch reports a length a few seconds after you touch the wall, so distance and splits update at the wall rather than continuously. SwimDelta shows a live pace estimate in between.
Open the session on your iPhone and tap Session diagnostics at the bottom, then share it with the email above. It records exactly how the watch tracked that swim.
