KookinSurf — Support

Last updated: 13 September 2026

KookinSurf is a surf logbook for Apple Watch and iPhone: sessions recorded from your wrist, offline tide predictions, automatic spot names, your boards and your stats — kept in Apple Health and your own iCloud, nowhere else.

Contact

For bug reports, questions, or a session that came out wrong, write to dimafern+kookinsurf@gmail.com. In the app, the same address is under Profile › About › Contact.

When reporting a problem, it helps to include your iPhone and Watch models, the app build number (Profile › About), and, for a session that looks wrong, its date.

Common questions

• Do I need an Apple Watch? To record sessions, yes. Sessions from other apps in Apple Health, manual entries and imported GPX or KookinSurf files work on the iPhone alone.
• The app shows no sessions. Check that KookinSurf is allowed to read and write Workouts in Settings › Apps › Health › Data Access & Devices.
• My boards are missing. Boards are stored in your iCloud. Make sure the device is signed in to the same Apple Account and iCloud Drive is on.
• Tide looks wrong. Tides are predictions from the nearest reference station, computed offline. At breaks far from any station the timing can be off; the station used is shown on the session.
• How do I back up my history? Profile › Your data › Export all sessions writes one JSON file you can keep anywhere and import back.
