Cancel any time during the trial and you won't pay a thing. **PART A EXAM SIMULATOR** Replicate the real My Know exam experience with all five question types: • Multiple choice • True/False • Matching • Fill in the blank • Drag and drop 15 questions. 40 minutes. No returning to previous questions — just like the real thing. Per-topic pass threshold tracking (COLREGs & Buoyage 90%, Nav Procedures 80%, Overall 70%) so you always know where you stand. **AI ORAL EXAM SIMULATOR** Practice your Part B oral with an AI examiner powered by Claude (Anthropic). Two modes: • **Session Mode** — A full multi-turn oral examination on a scenario. The AI asks follow-up questions, challenges your answers, and rates each exchange. • **Quick Assessment** — Submit a free-text answer and get a structured grading report: verdict (PASS / BORDERLINE / FAIL), score, key points checklist, missed topics, and examiner commentary. **SPACED REPETITION FLASHCARDS** Over 1,400 flashcards across all 10 modules, powered by the SM-2 spaced repetition algorithm. The app learns what you know and what you don't — surfacing the right cards at exactly the right time to build lasting knowledge, not just short-term memory. **10 COMPLETE MODULES** Navigation · COLREGs & Buoyage · Radar & ARPA · Meteorology · Watchkeeping & BRM · Ship Stability · Cargo Operations · Safety & Legislation · Emergency Response · Ship Handling All mapped to MIN 653 (Amendment 1, November 2024). **QUICK REFERENCE LIBRARY** 10 instant-access reference topics — not buried in lesson content, just the rules and data you need: IALA buoyage · COLREGs lights & shapes · Sound signals · VHF channels · Beaufort scale · Douglas sea scale · Distress signals · IAMSAR SAR patterns · Day shapes · Light characteristics Useful for exam candidates drilling topics. Just as useful for the OOW heading back to sea after a rotation ashore who needs a fast, reliable refresher before stepping onto the bridge. **GAMIFICATION** XP, levels, streaks, and daily challenges keep you consistent through months of exam prep. **WORKS OFFLINE** Everything — flashcards, lessons, quick reference, exam simulator — works completely offline. Whether you're studying at sea or on a long-haul flight. --- *The OOW Bible is an educational study tool and is not affiliated with, endorsed by, or produced by the Maritime and Coastguard Agency (MCA).

This release adds a mock oral you actually talk to. You are given a scenario, you answer aloud, and the examiner responds to what you said — not to a script. If you skate over the bit that matters, you get asked about the bit that matters. • Five examiners, each with their own manner and voice • Scenarios across all ten modules, drawn from the same MIN 653 / STCW A-II/1 syllabus as the rest of the app • A written report at the end: verdict, score, the points you covered, the points you missed, and the examiner's commentary • Your exam history is kept on your device and encrypted at rest Premium includes 3 oral exams a month. If you want more, session packs are available. Quick Assessment — the written practice you already have — is unchanged and still available as often as you like. This is practice, not an assessment of readiness. It is not affiliated with the MCA, and the examiner is an AI. ### 1.3.0 — 2026-08-06 This release is about reliability — the app getting out of your way when the connection doesn't cooperate. • Clearer sign-in. If sign-in fails because you're out of signal, or because your device's clock has drifted, you now get a plain-English explanation and the fix — not a raw error code. • Steadier purchases. A dropped connection partway through checkout or restore is now handled quietly and retried, instead of surfacing as a failure. • Oral Simulator resilience. Losing signal mid-session no longer ends your practice abruptly. • Referral accuracy. Rewards are now credited correctly on subscription renewals, and only once a real payment has been taken. • Performance improvements and minor bug fixes throughout. ### 1.2.9 — 2026-07-11 Offline Access is now free for everyone. • Study offline, free: download lessons, diagrams, 1,400+ flashcards and bridge reference material and revise anywhere at sea — no signal required. • Clearer Free vs Premium: a simpler side-by-side so you can see exactly what's included at a glance. • Performance improvements and minor bug fixes across the app. ### 1.2.8 — 2026-07-04 • Free interactive practice — COLREGs flashcards and a full mock exam, no subscription needed • Explore the app as a guest before creating an account • "Hard" no longer resets your flashcard streak • The mock exam now mirrors real Part A exam conditions, with feedback at the end • Improved security, performance and reliability, plus bug fixes ### 1.2.7 — 2026-07-03 • Smoother Sign in with Apple — your name is now filled in automatically, so there's less to enter when setting up your account. • Faster onboarding: the profile step no longer asks for details you've already provided. • Minor improvements and bug fixes.
