OpenABC brings listening, speaking, reading, and writing into one connected learning path: understand a word, write it by hand, say it aloud, and meet it again in real sentences and listening practice. LEARN WORDS WITH PICTURES Pointer lines connect each word to the exact object or part it describes, so meaning is understood before it is memorized. HANDWRITING DICTATION Write spellings directly on screen and receive on-device recognition. iPad supports both finger input and Apple Pencil. SPEAKING PRACTICE Practice situational phrases and full sentences with clear audio demonstrations and on-device pronunciation and intonation feedback. Recording only starts when you choose. GRAMMAR YOU CAN SPEAK Key structures appear inside useful, contextual sentences. Understand the situation, then say the pattern aloud instead of only answering grammar questions. LISTEN AND REPEAT ANY LINE Daily warm-ups, dialogues, and sentence-by-sentence content keep playback and speaking controls close to every line. CONTENT THAT GROWS WITH YOU Study vocabulary, everyday listening and speaking, life stories, children's content, graded readers, English audiobooks, exam listening, pronunciation, and spelling. Review is planned by vocabulary level, learning history, and memory intervals. MULTIPLE LEARNERS Create separate learner profiles on one device. Vocabulary level, progress, review history, and preferences stay independent for each person. OFFLINE AND AD-FREE Downloaded content works offline.
