Pageless

Pageless is the native Android client for Pageless, a self-hosted audiobook server. It is offline-first: browse your library, download books for offline listening, play without a connection, and sync your progress back to your own server over its token-authenticated JSON API.

You must run your own Pageless server; the app connects to a server URL that you configure on the login screen. No account or data is sent to any third party.

Server source and setup instructions:

Features:

• Browse your library, series, collections, and playlists.
• Open book details with metadata, chapters, bookmarks, and listening progress.
• Download books (audio and covers) for fully offline playback.
• Media3-powered background playback with notification and lock-screen controls, a mini-player, and a full Now Playing screen.
• Playback progress, bookmarks, and listening history sync back to your server, merged last-write-wins so multiple devices stay in agreement.
• Light, dark, and system themes.
