Examen Test PNB is a Flutter mobile app designed to help you prepare for the official PNB (Patrón de Navegación Básica) nautical licence exam in Spain. Available on Android and iOS — free with ads, with an optional one-time Premium upgrade. The app includes over 400 questions from the official exam bank, organised across the 7 syllabus topics. Features include unlimited practice tests, interactive flashcards for buoyage, COLREGS signals and nautical terminology, a fully illustrated study guide with images and diagrams, a real exam simulator with 40 random questions and a timer, error tracking to identify weak areas, and full offline functionality. The free version covers all content with ads. The Premium plan (€5.99, one-time payment) removes ads and includes lifetime access with future updates. Built with Flutter to deliver a smooth, native experience on both platforms.
