Dracula, Pride and Prejudice, The Count of Monte Cristo, Sherlock Holmes, Frankenstein, and about a hundred more, with the ebook and audiobook already aligned. Nothing to set up. BRING YOUR OWN BOOKS Already have the EPUB and the audio for the same book? Tribooks aligns them into one synced title. Your files do need to be DRM-free. Audiobooks locked to another app's player can't be imported. ONLY OWN THE EBOOK?

You get back a real read-along, with the text highlighting as the audio plays. AND THE PAPERBACK Point your camera at a page of the physical copy and Tribooks finds that spot in the ebook and the audiobook. Put the book down, pick your phone up, keep going.
