StrokeLab is a comprehensive swim analysis tool which tracks and visualizes a swimmer’s stroke rate, pacing, and splits to give a clear, detailed view of how a swim progresses from start to finish. It records each stroke, maps tempo changes on a smooth graph, and breaks down speed across every lap or segment. By turning race and training data into easy-to-read insights, StrokeLab shows exactly how rhythm, pace, and performance shift throughout the swim.
