KookinSurf

KookinSurf is a surf logbook for Apple Watch and iPhone. Start a session with a turn of the crown, paddle out, and come back to a record of where you surfed, for how long, at what tide, and on which board. ON THE WATCH • Start, lock and end a session with the Digital Crown — no fumbling with wet fingers • Heart rate and calories from the workout, GPS track of your session • Tide at paddle-out and at the end, predicted offline — no signal needed at the break • Pick the board you're riding before you go in • A tide complication for your watch face ON THE PHONE • Every session with its map, heart-rate chart and a 24-hour tide curve • Spots named automatically from more than 8,000 breaks worldwide, or add your own • Your breaks on a world map, grouped by country, with how often and how long you surfed each • Stats by year and month: sessions, time in the water, and a chart to see the seasons • Quiver: your boards with photos and sizes, and how many sessions each one has had • A tide widget for your chosen spot on the home screen YOUR DATA STAYS YOURS • Sessions are Apple Health workouts. Boards, spot names and ratings live in your own iCloud. There is no KookinSurf account and no server of ours holding your history • Already tracked surfs with another app? Import them from Apple Health in Profile, read-only — we never change or delete another app's data • Export everything to one JSON file — every session, track, heart rate, spot and board — and import it back on a new phone TIDES, OFFLINE Tide predictions come from harmonic constants for thousands of stations bundled inside the app, so they work on a reef with no coverage and in airplane mode. Each session records the tide at its start and end and the day's high and low. KookinSurf needs an Apple Watch to record sessions. Sessions from other apps, manual entries and imported files work on the iPhone alone.
