〽️
Real stroke detection
Counts strokes from phone IMU using cadence + dominant-axis oscillation. No magic numbers — handles waves, cars, and bumps.
📍
GPS that handles canyons
Kalman-smoothed track with accuracy-aware speed. Splits every 1 km, moving-time aware so a coffee break doesn't tank your pace.
🏝️
Built for outrigger crews
OC1 to OC6 and surfski. Track stroke rate, distance, and pace for every paddle — solo or with the whole crew.
🗺️
GPX + shareable links
Every session exports clean GPX. Flip a switch to publish a public link you can drop in a club chat.
🚣
Crafts that exist
OC1 / OC2 / OC6 / V1 / SUP / Surfski — different defaults for different boats. Not “Kayak (Other)”.
📡
Built for the offline put-in
Records fully offline. Uploads when you're back on signal. Your data sits in your account, not behind a paywall.
