Long press the map to drop a destination pin, send it to your Watch, then leave your phone on shore.
Feel a tap pattern when you drift — silence means you're on course. Configurable patterns for steer left and steer right.
A perpendicular finish line detects arrival even with GPS drift. No more missing your destination.
Route map, splits, heart rate, weather conditions, and efficiency score — all in one post-swim summary.
Water lock activates automatically. Works with screen dimmed. No looking up required.
Saves Open Water Swim workouts directly to Apple Health with heart rate and calorie tracking.
