Swimming Lap Tracker

Swimming Lap Tracker gives you precise manual control over laps, intervals and structured swim training on Apple Watch, with detailed workout analysis on iPhone. Mark laps with the Digital Crown or the Action Button on Apple Watch Ultra. You decide exactly when each lap or interval is recorded instead of relying on automatic lap detection.
