How trust works

Client for a self-hosted ebook and audiobook library. Browse, search, and read EPUB, MOBI, AZW3, FB2, CBZ, or PDF files with synced progress. Listen to audiobooks with background playback, sleep timers, and Chromecast support.

BookOrbit is a native Android client for your own self-hosted BookOrbit server — a personal library for ebooks and audiobooks that you control.

BookOrbit does not host any content itself. Point the app at your own BookOrbit server and get a fast, native way to browse, read, and listen to your library on your phone or tablet.

FEATURES • Sign in with username and password or your OIDC provider • Browse and search your full library, with smart scopes and collections • Author and series pages • Built-in ebook reader (EPUB, MOBI, AZW3, FB2, CBZ) and PDF reader, with progress synced to your server • Audiobook player with background playback, sleep timer, Chromecast and Android Auto • Download books for offline reading and listening • Upload and review new books with Book Drop • Your data stays on your server — no ads, no tracking, no analytics

REQUIREMENTS You need access to a running BookOrbit server to use this app. The app does not provide or host a server.
