SwimOnCourse
Health & Fitness
Free · Designed for iPad. Not verified for macOS.
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.
