LingoNova is an interactive mobile platform for learning English from A0 to C2. It combines structured lessons, dual-language audiobooks, spaced-repetition flashcards, progress tracking, and guidance from the Nova mascot to turn study into a consistent daily habit. Our team built an audiobook reader with synchronized word highlighting, one-tap translations, and customizable typography. Bite-sized ten-word flashcard sets include pronunciation, phonetics, and reinforcement quizzes for practical vocabulary development. Gamification features include daily streaks, XP, achievements, interactive 3D response cards, and motivational feedback. An offline-first architecture with caching and local fallbacks keeps lessons and quizzes available even when the server connection is interrupted.
