Lagrange Reader v1.0.0
Lagrange Reader 1.0.0
This is the first release-ready version of Lagrange Reader, an independent Android client for BookOrbit. It began as a personal project because I love BookOrbit and wanted a reliable way to read my library offline.
Highlights
- Offline-first library browsing and local books
- Two-way reading and listening progress synchronization
- Automatic replay of progress recorded during offline sessions after reconnecting
- EPUB, KEPUB, PDF, and CBZ reading
- Online CBR/CB7 preparation through the BookOrbit server
- Audiobook playback with chapters, seeking, speed control, and resume
- Reader themes, margins, text sizing, orientation lock, and keep-awake mode
- Multiple app themes, achievements, download policies, cache management, and server switching
Known limitations
- MOBI, AZW, AZW3, and FB2 are not currently supported.
- Offline CBR/CB7 still requires the BookOrbit server for RAR/7z extraction.
- Direct OIDC/SSO is not implemented.
- Wider device, accessibility, and unusual-format validation will continue after this release.
