Finns Motion Flow update A real swim-analysis app — see your strokes in 3D motion. ■ 3D stroke reconstruction Wear your Apple Watch while you swim and its motion sensors record your arm's path, drawing your stroke in 3D motion — the detail you can't see underwater. Rotate it from the side, top, and front. ■ Per-stroke form & technique Freestyle, backstroke, breaststroke, and butterfly are each analyzed — high elbow, straight arm, wrist direction at entry, and the catch → pull → push → recovery acceleration profile. ■ Coach report From an at-a-glance summary to session-by-session trends and the next drill to try, all in cards. What to refine, why, and how. ■ Calibration for better accuracy Set your arm length once and measurements get more accurate. See your strokes from your swim — now in 3D motion.
