HELM

The ticket comes down to one conversation: the MCA oral examination. HELM is built for it ā and for the years after it. HELM is a revision app for the MCA Officer of the Watch (Yachts) less than 3000gt certificate. The bridge between deckhand and officer. MOCK EXAMS ā TEST WHAT YOU KNOW Timed mock exams under real conditions, across the whole syllabus: multiple choice, true/false, matching and fill-in-the-blank, with a worked explanation on every question. Sit a full paper or drill a single module. THE ORAL ā REHEARSE IT OUT LOUD The AI Oral Examiner runs a spoken mock oral assessment. It presses for detail when an answer is thin, holds you to the standard an examiner would, and gives you a written breakdown afterwards: what you got right, what you missed, and the rule you should have cited. Four sittings a month, without booking anyone's time. LEARN THE SYLLABUS PROPERLY Sixteen modules covering the full OOW Yachts syllabus: ⢠Navigation & Passage Planning ⢠COLREGs ā Rules of the Road ⢠Lights, Shapes & Sound Signals ⢠Buoyage ā IALA ⢠Bridge Watchkeeping & BRM ⢠Meteorology ⢠Stability & Watertight Integrity ⢠Yacht Construction & Equipment ⢠Anchoring, Berthing & Ship Handling ⢠Tenders, Toys & Guest Operations ⢠Safety & SOLAS ⢠Firefighting & Emergencies ⢠Pollution Prevention & MARPOL ⢠ISM, MLC, Flag & Survey ⢠Communications & GMDSS ⢠Signals & Distress Lessons are typeset to be read rather than skimmed, with diagrams drawn to explain rather than decorate. DRILL UNTIL IT STICKS Spaced-repetition flashcards scheduled by the SM-2 algorithm, so a card comes back just before you would have forgotten it. What you find hard comes back more often. KNOW WHERE YOU STAND Readiness tracking across every module, so you can tell the difference between feeling ready and being ready. FOR JUNIOR OFFICERS, NOT ONLY CANDIDATES Passing is the start, not the finish. HELM stays on your phone afterwards as a revision companion: the full text of the Rules, lights and shapes, buoyage, signals and the sea scales, all searchable and all offline. Junior officers use it to keep the theory sharp between tickets and to check a detail without hunting through a publication. WORKS AT SEA Lessons, flashcards, mock papers and the whole quick reference run in airplane mode. Mid-ocean, in a lift, on a delivery ā it does not matter. Only the AI Oral Examiner needs a connection. QUICK REFERENCE, ALWAYS TO HAND ⢠COLREGs ā Rules 1-38 and Annexes I-IV, full text, searchable ⢠Lights & shapes ā an interactive atlas, every examinable configuration from three aspects ⢠IALA buoyage, Regions A and B ⢠Sound & light signals ⢠International Code of Signals ā single and multi-letter ⢠VHF channels ⢠Beaufort scale and Douglas sea scale ⢠Cloud recognition START WITH COLREGS, INCLUDED IN FULL The entire COLREGs module ā lessons, flashcards and mock exam questions ā is yours from the moment you install, offline, without an account. A subscription unlocks the remaining fifteen modules and the AI Oral Examiner. IN YOUR LANGUAGE The interface is available in Afrikaans, Arabic, Chinese (Simplified), Croatian, Dutch, English, French, German, Greek, Italian, Polish, Portuguese (Brazil and Portugal), Russian, Spanish and Ukrainian. Syllabus content stays in English, because English is the language of the exam. A built-in glossary gives you the English term with its definition in your own language, so nothing is lost in translation on the day. HELM is study, revision and reference material. It is not for operational navigation or decision-making at sea, and it is not an official MCA product.

Verdict
The clearest difference is update cadence: HELM at every 2 days against Bridgedeck Study's every 6 days. Bridgedeck Study's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.
