This app is a focused educational and revision tool for sailors, skippers, and maritime students who want an efficient way to learn, retain, and periodically refresh their understanding of the International Regulations for Preventing Collisions at Sea (COLREGs). It is designed for serious learners — including professional and advanced recreational mariners — who want a clear, distraction-free way to revisit complex rules, lights, shapes, and scenarios. Designed for long-term retention The app presents key COLREGs concepts in a structured, study-oriented format. By combining visual recognition with active recall and spaced repetition, it helps reinforce knowledge over time — making it suitable not only for exam preparation, but also for regular refresher use (for example every 6–12 months). Key features • Structured review of COLREGs navigation lights and shapes • Clear visual presentation of lights, shapes, and signals • Question-and-answer format to actively test understanding • Study, practice, and exam-style learning modes • Progress tracking stored locally on your device • Fully offline use after installation • No accounts, no ads, no tracking Built for focused study This app is intentionally simple and distraction-free. There are no advertisements, no subscriptions, and no internet dependency — just a reliable study tool you can use anywhere, anytime. Important notice This app is for training and revision purposes only. It does not provide real-time navigation assistance, operational decision-making, or situational awareness, and it does not replace official publications, onboard instruments, or professional judgment. You remain fully responsible for safe navigation and compliance with applicable regulations at all times. ## Marine Nav Lights Trainer Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/0a/4d/f0/0a4df09b-001d-4ae0-55f2-ec1a2b918f72/IMG_0172.jpg/1242x2688.png) -
