Open water has no lane lines. SwimOnCourse gives you one — felt through your wrist, invisible to everyone else. Use your iPhone to set your destination on the map and send it to your Apple Watch. Leave your phone on shore — it's not needed during the swim. When you're ready, tap Start Swim on your Watch. Your Watch guides you with haptic taps whenever you drift off course. The pattern tells you which way to turn. Silence means you're on the line. No looking up. No sighting. Just swim. After the swim, return to your iPhone to review your route, stats, and how closely you held the line. Navigation Cross-track error navigation maintains a fixed-width corridor — not a widening cone Configurable haptic patterns and intervals for left and right corrections Finish zone detection accounts for GPS drift so you never miss your destination Approaching and arrival alerts Workout Tracking Records Open Water Swim to Apple Health Distance, time, heart rate, calories, and 100-yard splits GPS route map with course corridor and finish zone overlay Weather conditions recorded at swim time Apple Watch Works standalone — no iPhone needed during swim Water lock activates automatically Pre-swim screen confirms haptic settings before you start Focus on your stroke, not your heading.
