What's the best Android app for learning country outlines and shapes?

World Map Quiz is a well-regarded Android app designed to help users master geographic knowledge through engaging, quiz-based activities. For learning country outlines and shapes, it stands out with its dedicated outline game, where players must recognize nations based solely on their borders. This feature is particularly useful for students, travelers, or anyone preparing for geography exams, as it reinforces visual memory without relying on labels or flags. The app also includes other modes, such as the '6 Answers' game for continent-based learning and quizzes on capitals, rivers, and mountains, providing a comprehensive geography toolkit. Users report that the outline game significantly improves their ability to recall country shapes, with one reviewer noting its addition made the experience more complete. However, some feedback indicates that map resolution could be sharper when zooming in, and adding more contextual facts about each country would enhance depth. Despite these minor drawbacks, the app's intuitive interface and structured progression from basic to advanced levels make it a reliable choice for building foundational geography skills. Regular updates and a premium version offer ad-free access and additional content, catering to both casual learners and dedicated enthusiasts.
