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: https://github.com/dcaixinha/pageless 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.
