BuoyFlash Sea Marks

BuoyFlash Sea Marks is an offline-first maritime buoyage trainer for recreational boaters, sailing students, and coastal skippers who need instant recognition of IALA sea marks and light cadences—without paper cheat sheets. Train on a huge night-capable buoy recognition stage. Study a rendered mark, then match its identity and animated light rhythm on oversized pattern pads. Switch IALA Region A or B, drill day shapes, and practice fog and sound signals with spoken cues. WHAT YOU PRACTICE • Lateral, cardinal, isolated-danger, safe-water, and special marks with common topmarks • Light cadences: flash (Fl), occulting (Oc), isophase (Iso), quick (Q), and very quick (VQ) • Day-shape and restricted-visibility sound-signal drills • Seeded mark families plus custom playlists you pin on device BUILT FOR REAL RECALL • Fullscreen buoy stage with day/night scenes and oversized answer pads • Animated lantern studio—tap the matching rhythm as the pattern plays • Weak-spot matrix that highlights missed mark families and cadences, then feeds targeted retries • Mastery map with star thresholds, spaced challenge rounds, and a cold-start continue card • Offline encyclopedia: color plates, light abbreviations, meaning summaries, and region notes • Home-screen widget with mark-of-the-day silhouette and a sample light cadence Designed as a deliberate recognition-and-cadence trainer—not a GPS plotter, catch diary, or generic flashcard deck. Core practice runs fully offline with local-only storage. No account and no network required for the main loop. Master real IALA marks and light rhythms so you can read the water faster when it counts.
