Foil Surf Tracker: BreakFinder

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 190+ GARMIN DEVICES SUPPORTED From fēnix 8 down to Instinct 2S.
