Why visual & contextual vocabulary works

Head-term apps compete fiercely on phrases like “vocabulary builder,” but many learners still struggle because flashcards feel disconnected from real life. Word Catcher focuses on photo vocabulary and reading vocabulary — the long-tail, high-intent ways people actually encounter new words while traveling, studying, or living in another language.
