📝 About this app
Navigation Marks is a compact reference for skippers, sailors and students learning the IALA Maritime Buoyage System.
Quickly identify lateral marks for Regions A and B, cardinal marks, isolated danger marks, safe water marks, special marks and new danger marks. Each entry shows the buoy shape, colour scheme, topmark and light rhythm so you can revise recognition rules before a course, exam or time on the water.
Why it helps:
- Covers the main IALA buoyage marks in one place
- Includes day and night views where available
- Explains colours, shapes, topmarks and light characteristics
- Works as a practical study aid for RYA, IYT and general seamanship training
- Built for quick lookup on iPhone and iPad
Use Navigation Marks as a pocket study guide when preparing for boating exams, refreshing buoyage rules or checking how a mark should be identified.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
