## Description

Free forever: the complete Rules of the Road, both sets, full-text search. Aspect Pro adds every drill, a full exam simulation, and progress tracking.

Pay once. Works offline. Your data never leaves your device.

No subscription, no account, no ads, no tracking.

The Rules of the Road module of the USCG exam is 50 questions, closed book, and needs 90% to pass -- five wrong and you fail. Aspect is built around that one fact.

FREE FOREVER
- The complete text of the International and Inland Navigation Rules, side by side, with every divergence between them flagged
- Full-text search -- type a bare rule number ("15") to jump straight to it
- Every question from the USCG's own published sample examinations

ASPECT PRO ($6.99, one time)
- Every light and shape configuration, drawn as original artwork you rotate to any aspect -- recognition is most of the exam
- Sound signals synthesised at the real one-second and four-to-six-second timing, International and Inland meanings side by side
- A full closed-book exam simulation: 50 questions, weighted to the real distribution, 90% to pass, timed
- Per-rule progress and weak-area tracking
- Build your own practice test by category and length, or print one on paper

LIMITS
This is a study aid. It does not satisfy the requirement in 33 CFR 83.01(g) to carry a copy of the Inland Rules on board -- consult NVIC 01-16 and carry an approved copy. Always verify against the current published edition.
