Study IALA Buoyage the Visual Way
The IALA buoyage system packs a lot of meaning into every mark. Colours, shapes, topmarks, and light rhythms each carry information, and keeping them all straight for an exam can feel like a demanding memory test. Maritime Master IALA Buoyage is built to make that revision clearer and a little more enjoyable.
It is a focused study and quiz app for iPhone and iPad that explains each mark with clear visuals and animated lights, offers exam-focused study tips, then tests what you have learned. It is a one-time purchase, works offline, and has no accounts, tracking, or ads.
Sixteen Marks Explained
The app covers sixteen marks across both IALA regions. You will find the four cardinal marks with their clock-face flash logic, the port and starboard lateral marks and preferred channel marks for Region A and Region B, and the isolated danger, safe water, special, and emergency wreck marks. Each one is presented in the same clear way so nothing feels out of place.
For every mark you can study its colour, shape, and topmark, its light characteristics and variants, where it is used, how to pass it, and a set of study tips. That consistent structure makes it easy to compare marks and to spot the small differences that often catch people out during revision.
Night Mode and Animated Lights
A night mode shows a mark's light flashing in real time beside a scrolling rhythm timeline. Seeing the flash play out next to its timeline helps the pattern stick far better than a static diagram, and it turns abstract rhythm notation into something you can actually watch unfold.
Build Any Light
The light simulator lets you build any IALA light from twenty rhythm patterns, including occulting, isophase, flashing, quick, very quick, ultra quick, and Morse. You can pick from five colours and adjust the periods and group counts, and the app generates the correct chart notation such as Fl(2+1) R 10s. It is a study tool and not a substitute for an approved course, but it is a neat way to connect what a light looks like with how it is written down.
Rhythm Reference
Alongside the simulator there is a categorised rhythm reference with animated examples. If you want to browse the different light rhythms grouped together and see each one animated, this is the place to look. It works well as a quick refresher before you sit down to a quiz.
Five Ways to Test Yourself
When you are ready to check your knowledge, there are five quiz modes: buoyage basics, naming buoys from images, light rhythms, animated light pattern recognition, and a fifty question mixed exam. Between them they cover recall, visual recognition, and the trickier business of reading a light by its rhythm.
A region selector lets you focus on Region A, Region B, or both, so you can tailor your study to the area you care about. Everything works offline, which makes it easy to revise on a train or anywhere without a signal.
For Study, Not Navigation
One important note before you begin. The visuals are stylised training aids for training and study only, not for real-world navigation; do not use it to identify marks at sea; always use official charts, light lists, and proper lookout. Think of the app as a revision companion that supports your study, not a replacement for formal training or official publications.
