WordPop is a vocabulary learning app built for people who want real results. Study English, Korean, or Thai through a structured word bank, interactive games, and custom decks you create from scratch. The built-in library covers 1,000 English words organized across 20 topics: Daily Essentials, Business English, Emotions and Feelings, Power Vocabulary, Colors and Nature, Food and Cooking, Family and Relationships, Travel and Places, Health and Body, Technology and Digital, Sports and Fitness, Art and Culture, Science and Nature, Money and Economics, Law and Society, Psychology and Mind, Academic Writing, Idioms and Phrases, Environment and Climate, and Time and History. Each topic contains 50 words graded from beginner to advanced. Korean and Thai libraries are also included. Three practice modes keep studying engaging. Flashcards let you review words at your own pace with pronunciation audio. Quiz mode tests you with multiple choice and fill-in-the-letter challenges. Pronunciation mode plays the word aloud and asks you to identify it by ear. Custom decks put you in control. Create your own word lists, add photos from your camera roll, and use the built-in camera scanner to capture words from physical books, menus, or study materials. Your decks support the same flashcard and quiz games as the built-in library. Progress is tracked automatically. Earn XP for every study session, maintain daily streaks, and watch your learned word count grow across every deck and topic. WordPop works in six interface languages: Vietnamese, Chinese (Simplified), English, Portuguese (Brazilian), Korean, and Thai. The app remembers your language preference and keeps your progress safely stored on your device.
