Libratory plays an audiobook over the real pages of the book, lighting up the sentence and the word being spoken as it reads. Double-tap a sentence to hear it again. Books are made on your Mac with the free Libratory desktop tool, which pairs a book with its narration and saves both as one synced EPUB. Send that file to your iPhone or iPad with AirDrop or the Files app, tap + on the shelf, and press play. Nothing is streamed, no account is needed, and everything works offline. The app comes with a short three-chapter guide already on the shelf. It is itself a synced book, so reading it is the fastest way to see what the app does.
