About this app

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 Built by windsurfers for the speed-surf community. Free. No ads. speedsurf.app

Latest release

What’s New

Version 2.2.0 Jul 29, 2026

The big reliability + on-the-water update. NEVER LOSE A SESSION Recording is hardened the way Apple does it and then some — your ride survives crashes, memory pressure, and iOS trying to suspend the app in your pocket. If anything ever interrupts it, the session is recovered automatically. Every GPS point is written to disk the moment it arrives. HEAR YOUR SPEED (no screen needed) Spoken announcements while you ride — "New 2 second record, 31.4 knots" — plus countable record beeps and a GPS-lost siren. Works with the phone locked, on mute, under your wetsuit, and your music keeps playing. LIVE BROADCASTING IS BACK Flip one switch and friends watch your session unfold in real time on speedsurf.app/live. You control who sees it. LOCK SCREEN DASHBOARD While recording, your lock screen shows your numbers in big black digits on bright green — readable in sun and spray: last 10s, your 5 best runs, Avg LAT, 2s max, alpha, 500m, each with how far you are from your PR. MORE • Give up to 50 coins to a session with one tap • Apple Watch: runs page, live heart rate, crash-proof recording • Faster, cleaner start screen Thanks for riding with us.
