About CRR Maritime
CRR Maritime is the offline-first study companion for the French Certificat Restreint de Radiotéléphoniste exam — the certification required by the Agence Nationale des Fréquences (ANFR) to operate marine VHF radios with DSC (Digital Selective Calling, known in France as ASN). The app turns the official 2025 ANFR study manual into an interactive prep tool with structured lessons, smart flashcards, themed quizzes, and a faithful mock exam that mirrors the real test.
The full content of chapters 1 to 3 of the ANFR manual is covered, including illustrated lessons on VHF panels, DSC screens, the CROSS coastal radio network, and the marine channel table. A Leitner-style spaced repetition system surfaces the cards you are most likely to forget, while themed quizzes help you target specific areas — general knowledge, operating procedures, or regulations. The 24-question timed mock exam reproduces the official 6/8/10 category split with a 22-second-per-question countdown, so you walk into the real exam already knowing the rhythm.
CRR Maritime works 100% offline with no account, no advertising, and no recurring subscription. One universal purchase unlocks the app on iPhone, iPad, and Mac. Your progress, weak-spot detection, and exam history all stay on your device — useful for reviewing on a passage with no signal, on a train, or in a plane.
Who is CRR Maritime for?
- Recreational boat owners equipped with a fixed marine VHF radio
- Skippers using a handheld VHF with DSC/ASN distress button
- Long-distance cruisers for whom the CRR is mandatory abroad (most countries outside France require it for VHF use)
- Candidates preparing for the permis plaisance côtier or hauturier who want to add radio competency
- Sailing schools and training centres looking for a reliable revision tool for their students
Why choose CRR Maritime?
CRR Maritime is built strictly around the official ANFR 2025 manual — the reference document the exam questions are drawn from — so what you study is exactly what you are tested on. The included diagrams, channel tables, and DSC screen captures match the visual material candidates encounter on the day of the exam.
The mock exam is the most faithful you will find: 24 questions, the same 6/8/10 category split as the real test, the same 22-second timer, and immediate corrections with explanations linked back to the source lesson. A complete history of your sessions lets you watch your score curve climb as exam day approaches, and weak-spot detection automatically suggests which chapter to revisit next.
Because everything runs locally, you can revise at sea on passage, train your VHF reflexes during a long sail, or run a final mock exam in airplane mode the night before the test. No personal data is collected, no tracking, no internet required — just you and the manual, in your pocket.
