Foil Surf Tracker: BreakFinder
· v1.0.5
About
The only Garmin app built specifically for prone foiling.
Generic surf apps don't understand foiling. They count paddle strokes as waves, miss pumping sessions entirely, and can't tell a 30-second foil ride from bobbing in the lineup. BreakFinder uses a detection pipeline designed for the unique signature of prone foil surfing — accelerometer-based flight phase detection, pump cadence analysis, and GPS speed fusion.
HOW IT WORKS
Every foil ride leaves three fingerprints on your watch sensors:
- Your accelerometer goes quiet when you're flying above water (no wave chop shaking the board)
- Your pumping motion has a recognizable 1–3 Hz cadence that no paddle stroke mimics
- Your GPS speed holds steady between pump bursts
BreakFinder combines all three into a single confidence score. A ride is only counted when flight-phase variance collapse, pump cadence, and speed all agree. Result: no phantom waves from paddling, no missed flights during low-speed pumping, no false starts from current drift.
WHAT YOU GET
- Automatic wave count & flight time — no button mashing mid-session
- GPS distance & max speed tracking with drift protection
- Heart rate, calories, activity zones
- Activity classification: paddling, foiling, pumping, idle
- Pre-session period picker: short wind swell, medium, or long ocean swell
- Three sensitivity modes: beginner, intermediate, performance
- Session saves locally, syncs to the cloud when connected
- Full session replay on breakfinder.surf with GPS tracks, heart rate & speed overlay
