Speedsurf.app

The best free GPS speed tracker on the water, iPhone and Apple Watch. Built by surfers, for surfers. No ads.

Every knot, every gybe, every personal best, for windsurf, wingfoil, kitesurf, foil and bike.

RECORD Press start and ride. The screen is numbers, not a map: 2 s max in your discipline's colour, Avg 5×10 beside it, your last runs underneath. The lock screen shows three numbers — readable in sun and spray while the phone stays under your wetsuit. Beeps and spoken announcements for every record, a GPS-lost alarm, all with the screen locked.

THE NUMBERS 2 s max, 10 s, Avg LAT (best 5 leg-separated runs), α500, 500 m, nautical mile, distance — the same engine as speedsurf.app, in knots or km/h.

GO LIVE Friends follow your track and speed on speedsurf.app/live. You choose who can watch.

APPLE WATCH Record from your wrist, no phone on the water. Live heart rate, Water Lock, your track syncs to the iPhone afterwards.

MORE The public feed of sessions worldwide. Personal records per discipline. Import from any GPS logger — GPX, FIT, Locosys, Motion, Vakaros, u-blox, ESP-GPS — or open a file from Files, Mail or AirDrop.
