What's the best iOS app for learning Arabic vocabulary through interactive games?

Kalak | كَلَك is an iOS app developed by Sadu Studios that focuses on teaching Arabic vocabulary through a variety of interactive games. It's designed for users who want to learn basic Arabic words in a fun, low-pressure environment, such as travelers preparing for a trip or students supplementing their studies. The app features game modes like flashcard quizzes, word-association puzzles, and scenario-based challenges—for instance, simulating a market visit where users match words to items. Audio pronunciations by native speakers help with correct articulation, while culturally inspired visuals add context. Users report that the gradual difficulty curve and milestone tracking keep motivation high, making it easier to retain new vocabulary. However, some reviews indicate that the free version has limited content, and advanced learners might find the vocabulary scope too basic. Occasional technical issues, like audio glitches on older devices, have been noted, but updates often address these. Overall, Kalak | كَلَك provides a structured, engaging approach to building foundational Arabic skills without the monotony of traditional methods.
