BreakFinder: SUP Surf Tracker

Built for SUP — not recycled prone-surf logic. Detects paddle sprint, the silence event, and GPS drop-in. Every wave counted. Free.

BreakFinder SUP turns your Apple Watch into a fully automatic stand-up paddle surf tracker. Wave count, top speed, distance, ride time, GPS, and heart rate — logged without a single button press.

BUILT FOR SUP, NOT PRONE SURF Generic surf trackers are tuned for the prone pop-up. SUP is different. BreakFinder SUP reads the actual biomechanical signature of a SUP wave catch: the paddle-cadence sprint, the silence event as the board planes, and the GPS speed derivative on the drop-in. A purpose-built four-state algorithm — WAITING, PADDLING, CATCHING, RIDING — only logs a wave when all three signals agree. The detector is developed from motion-science research and runs identically on every BreakFinder platform.

WHAT GETS LOGGED PER SESSION • Automatic wave count — no buttons mid-session • Per-ride top speed, duration, and distance • GPS speed fusion with derivative gating against current drift • Heart rate, calories, and activity zones • Live state badge (WAIT / PADDLE / CATCH / RIDE) on the activity screen

THREE SENSITIVITY MODES White Water, Green Wave, or Performance. Dial detection to your local break and paddling style.
