Smart AudioBook Player is an innovative Android application tailored for audiobook enthusiasts. Unlike standard music players, it offers features like categorizing books into read, unread, or new, and allows users to create a character list. It includes a sleep timer for automatic shutdown and can resume playback with a simple phone shake. The app maintains a playback history and provides a home screen widget for easy control. Users can designate a specific folder for their audiobooks, ensuring an organized library by excluding other audio files, and it supports various audio formats including mp3 and m4b.
