About this app

Welcome to Prologue: the missing premium Android experience for your self-hosted audiobook library.

Built specifically to connect to your personal Audiobookshelf server, Prologue brings your entire catalog of audiobooks to your pocket with a buttery-smooth, native interface that feels right at home on modern Android devices. Whether you are commuting, taking a road trip, or winding down for the night, Prologue ensures your stories are always ready to play.

✨ Key Features:

🎧 Advanced Audio Player
Enjoy a highly customizable listening experience. Adjust playback speeds to your exact preference (from 0.8x up to 2.0x), skip through tracks, and utilize smart sleep timers that can automatically pause playback after a set time or at the exact end of your current chapter.

📚 Beautiful Library Management
Your library has never looked better. Prologue seamlessly pulls in your Books, Collections, and Series into a stunning, responsive grid. Instantly search your entire catalog by title or author, and browse through curated series with beautiful multi-cover collages.

☁️ Bulletproof Syncing
Never lose your place again. Prologue aggressively syncs your listening progress with your Audiobookshelf server in real-time. Start listening on your PC browser, and Prologue will pick up the exact second you left off on your phone.

📶 Offline Downloading
Going off the grid? No problem. Download your massive audiobooks directly to your device's internal storage or an external SD card with a single tap. Manage your downloaded files easily and listen anywhere without using a drop of mobile data.

🎨 Native Android Design
Prologue is crafted with Google’s Material Design 3 guidelines. It fully supports "Material You" dynamic theming, pulling gorgeous colors directly from your device's wallpaper. Prefer the dark? Switch seamlessly between Light, Dark, and true AMOLED Black themes to save battery and reduce eye strain.

⚙️ Requirements:
Prologue is a client app and requires an active, self-hosted Audiobookshelf server (v2.0.0 or higher) to function.

❤️ Support the Developer:
Prologue is a passion project built for the self-hosting community. The app is completely ad-free and tracking-free. If you love the app and use it every day, you can use the optional "Support the Developer" buttons in the Settings tab to buy me a coffee and help fund future development!

(Note: Prologue does not provide any audiobooks or media files. All media must be provided and hosted by the user via Audiobookshelf.)
