Book Reader turns the PDFs and EPUBs you already have into a library you actually finish. Add a file from Files and it lands in your library — long texts go to Books, short ones to Documents. The file is copied into the app, so your original stays where it is and your reading works offline. READING Four themes: Light, White, Night and Old Book. Pinch to zoom, pan with two fingers, jump to any page, and pick up where you left off. Search inside a book and tap a result to land on that page. HIGHLIGHT, NOTE, REMEMBER Press and hold a sentence and an action bar appears. Highlight it, or save it as a note with its quote attached — the Notes tab groups notes by book, and tapping one takes you back to that page with the text still selected. FLASHCARDS Turn a selection into a card: the sentence becomes the front, you write the answer on the back. Cards land in Today, Pending and Learned, and you rate each one Again, Good or Easy. ALSO Bookmark any page. Search your library by title or author, inside a book, or across your notes. Keep the questions that come up while reading in one place. No account, no sign-up. Everything stays on your device.
