Read full descriptionHide full description
Your device can now perform a spelling quiz!!!! Use the Settings tab to enter the words and customize the prompt for a correct or wrong answer. Words are separated by a carriage return. Spelling Quiz can also be used for testing in other languages. Use a carrot (^) to separate the word to speak and the other languages spelling. For example one^uno, would speak 'one' but the person taking the quiz would enter 'uno' to answer correctly. After the quiz, if any words are entered incorrectly, the user has the option to be quizzed again on just the incorrect words.

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.

Verdict
The clearest difference is update cadence: Master at fortnightly against Spelling Quizzer's every 44 months. Spelling Quizzer's advantage is device support (4 vs 2) and price ($0.99 vs $1.99). On ads, in-app purchases and iOS requirement there is nothing between them.
