Read full description

Read with your eyes, your ears, or both at once. Biblio is your library for books, podcasts, videos, photos and your own files. Text and audio run together: the highlighted word shows where you are, and when you look away, you keep listening from the same spot. WHAT YOU WILL FIND IN BIBLIO - Synchronized reading: text and audio at the same time, with the current word highlighted. - Free classics of world literature from Project Gutenberg and the Czech National Digital Library, with covers and edition details. - Podcasts and YouTube channels: subscribe, and new episodes and videos arrive in your library on their own. - Your own files: EPUB, PDF, audiobooks, songs from your Music library, videos, photos and scanned pages. Your recordings and videos can be transcribed into text. - Photos and albums: a viewer with captions, automatic photo descriptions and video summaries. - Presentations: combine photos, videos, music, captions and passages from books into your own story, play it, even on your TV via AirPlay, or export it as a video. - The Librarian: ask what to read next. It finds, adds and downloads. - A reader with your choice of font, size and colors, a progress indicator and read-aloud with your device's voice. - Wherever you are: iPhone, iPad, Mac, CarPlay and Apple Watch. Your reading position syncs through iCloud. FOR EVERYONE Biblio is built for sighted and blind readers alike.

Macan Library and Printing House for the Blind (KTN), the Digital Documents Library (KDD) and the Camelot electronic newspapers and magazines.
