A calm, in-depth, smart swim diary of your own — as still as the water itself.
Every session on your Apple Watch is imported automatically and laid out on a single timeline: heart-rate zones, pace, stroke, SWOLF, and lap distance.
Grow an avatar, collect medals, and both discover and improve the swim style your data reveals.
Not just a list of numbers, but a single swim told as a story — with no intrusive ads, focused purely on swimming.

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.
