Find the line you remember. Keep reading where it leads. Readune is an EPUB and PDF reader for the books you bring. Import your files, search across their text, or listen with natural voices that run on your device. No Readune account is required. SEARCH ACROSS YOUR LIBRARY Remember a phrase but not the book? Search the indexed text of your library in one place. See matching passages grouped by book and jump into the text. Search and indexing happen on your device. Chinese text is searchable within sentences, too. BRING YOUR OWN BOOKS Read EPUB, PDF and comics in CBZ or CBR. Import TXT, HTML, Markdown, FB2 and unprotected MOBI or AZW3 files; supported conversions happen on your device. Add files from Files, the Share sheet, drag and drop, or Shortcuts. MAKE ROOM FOR READING Choose Light, Dark, Warm or an E-ink-inspired grayscale theme. Adjust text size, line spacing and margins for reflowable books. Use pages or continuous scrolling. The E-ink mode simulates a paperlike screen with reduced animation; it does not turn your display into E Ink hardware. LISTEN AT YOUR PACE Read Aloud follows sentences with natural voices that run entirely on your device, or with your system voices, and offers playback speed, a sleep timer, background audio and lock-screen controls. Natural voices for more than 30 languages, including English and Chinese, are a one-time download. Free readers get three unlimited days of natural voices from first use, then 10 minutes a day; system voices are always unlimited. Voice availability varies by device and language. KEEP YOUR PLACE Use chapter navigation, bookmarks, in-book search and reading progress. Read comics in either direction. OPTIONAL READUNE PLUS Core importing, reading, library search and Read Aloud with system voices work without Plus. Plus adds unlimited natural voices, optional book-file sync through your own iCloud Drive, a highlights notebook, smart shelves, reading statistics and individual book themes. Choose a monthly or yearly subscription, or a lifetime purchase. Where an introductory offer is available, the app shows its terms before you subscribe. Subscription payments are charged to your Apple Account; subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your account settings. YOUR FILES, YOUR CHOICE No ads or tracking. Natural voice packs download once from public model hosts or Readune’s download mirror; speech is then generated on your device, and the text being read is not sent anywhere. Reading positions, bookmarks and preferences can sync through Apple’s iCloud key-value storage. Book files sync only when you enable Plus library sync. Readune does not operate a server that receives your books or searches. Bring your own DRM-free files, or start with the included public-domain sample book. Books shown in screenshots are original illustrations of an imported library and are not included. Image-only books and scanned PDFs without a text layer are not full-text searchable; no OCR is included. Layout and Read Aloud support depend on the file.
