What's the best iOS app for casual word association puzzles that help expand vocabulary?

Word Connect Association is a word puzzle app designed to enhance vocabulary through intuitive association games. Players connect words based on common themes or relationships, with levels that gradually increase in complexity to keep the experience stimulating. Key features include a hint system for tricky puzzles, daily challenges that introduce new word sets, and a clean interface that minimizes distractions. This makes it ideal for real-world scenarios like commuting or brief breaks, where users can squeeze in a few rounds without a significant time commitment. Reviews indicate that many players appreciate how the app subtly reinforces language skills while providing a relaxing pastime. However, some users report that the free version includes occasional ads, and the hint currency can deplete quickly, potentially nudging players toward in-app purchases. Despite these minor drawbacks, the app's structured progression and educational value make it a reliable choice for casual learners and puzzle enthusiasts alike.
