Reflashcard is a reader that turns the words you meet into vocabulary you actually keep.

Open a book from the built-in library — 500+ titles, nothing to buy or import — or bring your own PDF. Tap any word you don't know, and Reflashcard writes a flashcard for it on the spot: a clear definition, an example, and the exact sentence you found it in, so you never lose the context that made it memorable.

📚 START READING IMMEDIATELY
• 500+ books already inside — classic literature, graded readers sorted by CEFR level, and short true-story articles. No setup, no hunting for material.
• Many come with audio narration and a full transcript, so you can read and listen at the same time.
• Bring your own PDF too — textbooks, novels, articles. It's parsed on your device and never uploaded; only the word you tap and its sentence are sent to build the card.
• Paste a YouTube link into Listening Lab and turn its transcript into tappable, clickable vocabulary as well.

⚡ WHY IT STICKS
• Spaced repetition — cards come back right before you'd forget them, using the same scheduling algorithm serious language learners already trust.
• Real context, not a word list — every card remembers the sentence and page it came from. Tap it and jump straight back.
• A few minutes a day beats cramming — build a streak, not a backlog.

🧠 BUILT FOR ACTUALLY LEARNING
• Add Word — type any word you thought of and get a full card, no reading required.
• Reinforce — short drills (multiple choice, matching, fill-in-the-blank, speed rounds) that ask for the same word a different way each time.
• Explain or translate what you select — highlight any word or phrase and get its meaning in context, in your own language, without leaving the page.
• Track your progress — streak, retention rate, and a forecast of what spaced repetition is bringing back next.
• Works offline — your decks and review queue sync automatically once you're back online.

🔒 PRIVACY, PLAINLY
• Your PDF's contents never leave your device — only the word and sentence you select do.
• No ads, no advertising identifiers, no third-party analytics.
• Export everything you've made, or delete your account and every row of your data, any time, from inside the app.
