Surf Log is a personal surf journal for surfers who want a clear record of every session: where they surfed, when they paddled out, which board they rode, how it felt, and what the conditions were like. Log the details that matter after each surf: - Spot or break - Date, time, and duration - Session rating - Surfboard used - Wave, wind, tide, and ocean conditions - Notes, goals, and habits Build a useful history of your surfing. See where you have been surfing, which boards you have been riding, what conditions worked, and what you were focused on in the water. Surf Log is made for surfers, not generic workout tracking.

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, on which board — and every wave you rode. 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 • The tide now and the next high or low, predicted offline — no signal needed at the break • Water temperature measured by the watch itself (Apple Watch Ultra, Series 10 or later) • Pick the board you're riding before you go in • "Still surfing?" — a tap on the wrist if you leave the water on a boat or in a car with the session still running • A tide complication for your watch face ON THE PHONE • Every session with its map, your waves, the tide through your session and a heart-rate chart • Waves found in your track: how many, how far, how fast. Tap one to replay it, choose how strict the count is, and strike out the ones that weren't waves • Tilt and turn the map to see the break the way you surfed it • Spots named automatically from more than 8,000 breaks worldwide; search Apple Maps for any other, or add your own • Your breaks on a world map or a globe, grouped by country, with how often and how long you surfed each • Trips: sessions grouped by where you travelled, each under a photograph of the place • 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 • Share a session as a picture, ready for Instagram: your rides on the satellite map with the numbers FORECAST • Swell, wind, tide, sunrise and sunset, air and water temperature for the next seven days, anywhere on the map • Swell arrows across the map, so you can see what's arriving where • A home-screen widget with the day's tide, swell and wind at your spot; tap it for the full forecast 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. GPX and Garmin FIT files import too • Export everything to one JSON file — every session, track, heart rate, spot and board — and import it back on a new phone TIDES, OFFLINE Tides are worked out on your device: from a tide gauge where one stands near the break, and from a global ocean tide model everywhere else, so each break gets its own tide rather than one borrowed from a harbour far away. They work on a reef with no coverage and in airplane mode. The forecast needs a connection; everything else works without one. KookinSurf needs an Apple Watch to record sessions. Sessions from other apps, manual entries and imported files work on the iPhone alone.
