COLREGS Coach for iPhone
Know the lights.
Know what to do.
Train navigation lights, day shapes, and sound signals until recognition becomes automatic.
App Store listing coming soon.
Built for recognition
See it as you’ll see it at sea.
Image-first cards put the signal before the wording. Study vessel configurations from ahead, port, starboard, and astern.
Lights, shapes & sounds
One signal.
One clear answer.
Move from recognition to meaning, then check the exact rule behind it. Color-blind labels can identify every light dot without relying on color alone.
- Night lights and day-shape diagrams
- Timed quizzes by topic or mixed
- Rule reference on every card
- International COLREGS and US Inland variants
