Word Cards is an English vocabulary app built around seeing, hearing, recognizing, and reviewing words. Spend a few minutes a day building a practical foundation of everyday English words and phrases. Explore topics including animals, food, transportation, colors, daily life, and phrases. Each topic uses picture cards with the English word, a translation, and system pronunciation to make new vocabulary easier to understand and remember. Choose a topic and start a daily or full learning session. After a round of cards, practice with short activities such as listening and choosing a word, choosing a word from a picture, and matching words. Recently learned cards can be revisited from the review area. Word Cards saves your recent position, learning records, and study streak, and provides simple statistics so you can see your progress. Learning data stays on your device. No account or sign-in is required, and you can export or import a local backup using the system file picker. Word Cards is designed for English beginners, everyday vocabulary practice, and learners who want a focused way to study in spare moments.
