About

Passage

Read full description

Learning English becomes so much easier when you actually enjoy what you're reading. Passage is an English reading and English listening app built for people who want real progress, not another app they delete after a week. Every passage inside Passage is short, calibrated to your exact English level, and genuinely interesting. Instead of boring textbook sentences, you'll read about real curiosities, science, culture, history, food, travel, and relationships: the kind of English reading content you'd actually want to read even if you weren't learning a language. English reading is one of the fastest ways to grow your vocabulary and improve your understanding of real English. But most English reading apps stop there. Passage goes further by combining English reading with English listening in the same experience. Every passage comes with synchronized English audio narration, so as you read, you're also training your English listening skills, with word-by-word highlighting that keeps your eyes and ears working together. This combination of English reading and English listening builds the foundation you need before you can speak English with real confidence. You can't speak what you don't understand, and Passage helps you understand real English first: through reading, through listening, and through vocabulary learned in context rather than memorized in isolation. Choose your English level from six CEFR levels, A1 through C2. Whether you're a complete beginner just starting your English reading journey, or an advanced learner preparing for IELTS or TOEFL, Passage adjusts to exactly where you are. Beginners get short, simple English reading passages with basic vocabulary. Advanced learners get longer, more sophisticated English reading material with nuanced vocabulary and complex sentence structures. Tap any word while reading to see an instant translation into your native language. No need to leave the passage or open a separate dictionary. Tap any full sentence to see a complete translation, so even the trickiest English grammar becomes clear. Save any word you want to remember, and build your own personal English vocabulary list drawn from real English reading, not random flashcards disconnected from context. After each passage, answer a short set of English reading comprehension questions to check what you understood. This isn't a test designed to make you feel bad. It's a quick way to confirm your English reading comprehension is actually improving over time. Choose from eight categories built around real curiosity: Nature & Environment, Food & Health, Culture & Traditions, Technology & Innovation, Travel & Places, History & Curiosities, Science & Body, and Relationships & Daily Life. There's always something new to read, and because every passage is short, you can fit English reading and English listening practice into just a few minutes a day. Passage supports translations in eight languages, so no matter what your native language is, every word and sentence you tap will make sense immediately. If you've tried other English learning apps and felt bored, overwhelmed, or like you were memorizing words you'd never actually use, Passage was built differently. English reading practice should feel like reading, not like homework. Start with any topic that interests you. Read. Listen. Understand. Every passage brings you one step closer to reading and understanding English the way native speakers actually write it. Some passages and features are available with Passage Premium, a subscription that unlocks full access to all levels, categories, and passages.
