Speedsurf.app

Now: live broadcasting, spoken run announcements you hear under your wetsuit, and rock-solid recording that never loses a session.

Track windsurf, wingfoil and kitesurf sessions live — every knot, every gybe, every personal best.

SpeedSurf turns your iPhone, iPad and Apple Watch into a precise water-sports speedometer. Press start, ride, and watch your real-time speeds, leg averages and α500 unfold on a map. Stop, save, and compare against your own records and the global feed.

—

SPEED METRICS • Real-time speed in knots or km/h • Best 2-second peak, best 10-second run, Avg LAT (top-5 leg-separated) • α500 — best 500 m run with start and end within 50 m, the windsurfer's gold standard • Top speed, total distance, session duration

—

BUILT FOR THE WATER • Your lock screen becomes the display: giant digits on high-contrast green, readable in sun and spray while the phone stays under your wetsuit • Spoken run and record announcements — hear your speeds and personal bests without looking • Record beeps and a GPS-lost alarm that keep working with the screen locked and the phone on mute • Every metric shows how far you are from your personal record, live

—

GO LIVE Broadcast your session in real time. Friends and rivals follow your track and speed on speedsurf.app/live, and you choose who can watch — public, friends, or private.

—

APPLE WATCH Record straight from your wrist, no phone needed on the water. A Workout-style live page, your best runs, live heart rate, and Water Lock that arms automatically. Your full track syncs to the iPhone when you're nearby.

—

COMMUNITY & PROGRESS See the latest public sessions worldwide, filter by discipline, and rate a ride. Personal records are tracked per discipline — best 2s, best 10s, α500, fastest 500 m, nautical mile and best hour — so your wingfoil PRs never get steam-rolled by your windsurf maxes.

DEVICES • iPhone and iPad • Apple Watch — standalone recording • Live Activities on Lock Screen and Dynamic Island
