Name: BreakFinder — SUP Surf Tracker
Rating: 3.7 (3 reviews)
Author: breakfinder.surf

The only Garmin app built specifically for stand-up paddle (SUP) surfing.

Generic surf trackers are built around the prone "pop-up" — that explosive
push-up off the board that signals a wave catch. SUP surfers don't pop up.
We're already standing. So generic apps either miss our rides entirely or
count every paddle stroke as a wave. BreakFinder uses a detection pipeline
designed around the actual biomechanical signature of SUP surfing.

HOW IT WORKS

A SUP wave catch leaves three fingerprints on your watch sensors:

- Your paddle cadence surges into "First Gear" — short, hard sprint strokes
  above 2 Hz as you chase the wave's phase velocity
- Then your paddle goes silent the moment the board planes onto the wave —
  the Silence Event
- Your GPS speed jumps with a steep positive derivative (the drop-in)

BreakFinder's 4-state finite-state machine — WAITING → PADDLING → CATCHING
→ RIDING — only counts a wave when all three signals agree, with hysteresis
to reject paddle-side switches. Result: no phantom waves from chop or
current drift, no missed catches, no false starts from paddle-out sprints.

WHAT YOU GET

- Automatic wave count — no buttons mid-session
- Per-ride duration, top speed, and distance (logged separately to your
  session FIT file as laps)
- GPS speed fusion with derivative gating against current drift
- Heart rate, calories, activity zones — standard FIT fields
- Live state badge: WAIT / PADDLE / CATCH / RIDE on the activity screen
- Sessions save locally on the watch, sync to your account when connected
- Full session replay on breakfinder.surf with GPS tracks and per-ride
  speed overlay

WORKS OFFLINE

The detection pipeline runs entirely on the watch — no phone connection
needed during the session. Sync happens after, when you're back in range.
Your privacy stays on the device until you choose to upload.
