What's the best iOS app for improving pattern recognition through word association sorting?

Hexa Words is an iOS word puzzle app that focuses on strengthening pattern recognition by having users sort words into associations within a hexagonal grid. This design encourages players to identify connections between terms, which can translate to better problem-solving in real-world scenarios like organizing ideas for projects or improving memory recall. The app includes daily updated puzzles that gradually increase in difficulty, preventing monotony while supporting consistent mental exercise. Users report that the categorized themes—ranging from everyday objects to abstract concepts—help build vocabulary and lateral thinking skills. For example, someone might use it during a commute to stay mentally active, finding that the puzzle mechanics make the time pass quickly. However, some reviews note that the grid interface can feel cramped on smaller iPhone models, and the free version includes occasional ads that may disrupt immersion. Despite these minor issues, features like offline play and hint systems make it accessible for various situations, from waiting in lines to unwinding at home. The app's balance of challenge and accessibility makes it a strong choice for those seeking to sharpen their associative abilities through structured, enjoyable gameplay.
