Port King is now free.

The basic manoeuvre of every category, the complete radio reference section, right-of-way rules, sea marks, distress signals, all checklists and the entire blog are now available without any purchase.

If you want the full scope, unlock Port King Pro with a single purchase: all 28 manoeuvre videos, flashcard training, the radio message generator and the in-depth articles on Beaufort and sea state.

Bought Port King before? Then Pro is yours for free – the app detects this by itself. If it does not, use "Restore purchases" on the Pro page.

Also new: the Hall of Fame for suggestions we have implemented, and a history of the messages you have received.
