Master-Nav is a progressive COLREGS learning system developed by a Master Mariner. The COLREGS are notoriously difficult to learn and retain — Master-Nav makes it significantly easier through an interactive system built around how your brain actually works. Instead of guessing through random question banks, Master-Nav guides you step by step through every rule from start to finish. Wrong answers are revisited until the rules stick — properly. Complex regulations are broken down into learnable chunks — bite-sized sections supported by mnemonics, memory aids and interactive visuals designed around how the brain actually retains information. Every incorrect answer is shown graphically alongside the correct one — immediately clear, no confusion. And with a single tap, the relevant COLREGS rule is accessible from any question at any time. Master-Nav covers COLREGS Parts A to D — General, Steering & Sailing, Lights & Shapes and Sound & Light Signals — plus Annex IV Distress Signals. Over 1000 questions in multiple formats, with a dedicated Practice Section that tracks right, wrong and unanswered so you always know where to focus. COLREGS — the easy way.

Molo teaches isiXhosa to English and Norwegian speakers with a real voice on every word, the clicks first, and short daily lessons that stick. Every piece of content is approved by an isiXhosa editor before a learner sees it. WHAT MAKES MOLO DIFFERENT • A real voice on every word: no synthetic speech reaches a learner. • The clicks (c, x, q) are drilled as first-class exercises: listen to them and tell them apart. • Grammar forms come from a rule-based generator checked against forms a fluent speaker has signed off, never from a language model. • Nothing is published without a human isiXhosa editor's approval. • Short lessons, spaced review, streaks, weekly leagues, and three mascots: the sunbird, the penguin and the crane. WHY ISIXHOSA About 10 million people in South Africa speak isiXhosa as their home language, the second most spoken home language in the country and one of the three official languages of the Western Cape. It is the language of Nelson Mandela and Desmond Tutu, and of Miriam Makeba's "Click Song". Molo is free to start. Molo Plus adds unlimited hearts and more, as a monthly or yearly subscription that renews until cancelled in your App Store settings. Norsk: Molo lærer bort isiXhosa til engelsk- og norsktalende, med en ekte stemme på hvert ord, klikkelydene først, og korte daglige leksjoner som sitter. Alt innhold godkjennes av en isiXhosa-redaktør før noen lærer det. Terms of Use: https://hellomolo.com/terms Privacy Policy: https://hellomolo.com/privacy

Verdict
The clearest difference is price: Molo at Free against Master's $1.99. Molo also leads on update cadence (every 3 days vs fortnightly). Master's advantage is in-app purchases (none vs 2). On ads, device support and iOS requirement there is nothing between them.
