BreakFinder: Foil Surf Tracker
Auto flight detection on wrist
Free · Designed for iPad. Not verified for macOS.
Purpose-built for prone foiling. Detects takeoff, flight, and pumping automatically — no buttons. Counts flights, pump cycles, and touchdowns. Free.
BreakFinder Foil tracks your prone foiling sessions automatically on your Apple Watch. Not recycled surf logic — a detection pipeline rebuilt from the ground up for the biomechanics of foiling.
AUTOMATIC FLIGHT DETECTION
No buttons. No guessing. A sensor-fusion algorithm tuned to foiling detects every phase of your ride. Takeoff, flight, and pumping are recognised and logged automatically — including connected rides where pump chains keep you flying.
WHAT GETS LOGGED
• Flight count and total flight time
• Pump cycles per flight
• Connected ride chains
• Touchdown count for progression tracking
• Top speed and distance
• GPS track and heart rate for every session
5-STATE DETECTION ENGINE
Developed from motion-science research, the FSM moves through Idle → Paddling → Takeoff → Foiling → Pumping and back. FFT-based pump detection locks onto your personal pump frequency. Variance-collapse flight detection catches the clearest positive foil signal. Two-stage tripod takeoff detection eliminates false positives from surf pop-ups.
OFFLINE CALIBRATION
Select short, medium, or long wave period before the session. The app calibrates pump-frequency expectations without any internet connection — works in the lineup, not just at the pier.
RUNS ON YOUR APPLE WATCH
Detection runs on-device, standalone — no phone needed in the lineup. One free BreakFinder account keeps your foil history.
YOUR FOIL LOG, ON YOUR PHONE
Sessions sync automatically to the BreakFinder iPhone app — mapped, charted, and ready to review. Flight count, pump cycles, speed, and GPS track at a glance. Your complete foil history in one place.
PRIVACY FIRST
Works offline during sessions. No tracking, no ad cookies. GDPR/DSGVO compliant. Delete your account anytime from inside the app.
