The app, features a light and shapes visual search engine, a thematic rule reference, and provides revision tests as well as 3D rendering for Colreg rules 20 to 31.
Cards have been introduced for self-learning.

For each rule, you can change the observation point on the 3D rendering view by a touch/drag action.

The visual search engine gives you the ability to find any Colreg rule in seconds. For example, for a "green light + red light + white light" the app will identify the associated rule.

The app is free with premium content, ad free, and does not require an internet connection. It does not collect or share any user data.
