Liseur v0.1.1

This is the first release of Liseur, an open-source Android EPUB reader designed for reading sideloaded books, fine-tuning typography, and connecting to a calibre-web server.

Reading

• Paginated EPUB reader with full-screen view, tap zones, and optional volume-key page turning.
• Paper-like sliding page turn animations that switch to instant transitions when tapping quickly.
• Reading settings menu to adjust font size, line spacing, margins, and screen brightness.
• Four color themes: Light, Sepia, Dark, and Pitch Black, with interface chrome following the active theme.
• Bundled open-licensed fonts including Literata, Vollkorn, Atkinson Hyperlegible, and Inter, alongside OpenDyslexic, Accessible DfA, and iA Writer Duospace. The font menu previews each typeface in its own style.
• Reading progress display showing estimated time left in the chapter, page numbers, or overall percentage, plus a chapter scrubber with jump-back pills.
• Table of contents with chapter nesting and automatic scrolling to your active location.
• Text selection menu with four highlight colors, notes, page bookmarking, and Markdown export via the system share sheet.
• In-book search with live-streaming results and inline text highlighting.
• Word definition cards powered by Wiktionary, with support for installed dictionary apps and system text actions.
• Layout engine respects cutouts and gesture bars so hiding reading controls does not reflow the text under you.

Library

• Folder scanning to automatically import EPUB titles, authors, and cover artwork into a shelf grid.
• Library sorting by title, author, recent activity, or download date, with proper handling of leading articles.
• Option to launch straight into your current book when opening the app.
• Visual completion badges for finished books, applied automatically at the end of a book or toggled manually.
• Background scanning to catch books added, updated, or removed outside the app.
• Context menus to manage local files, remove downloaded copies, or delete books.
• Automatic Android system backup support for library records, reading positions, settings, and notes.

calibre-web

• Connect to a calibre-web server with existing user credentials over HTTPS or plain HTTP.
• Browse remote catalogs, view server cover art, and download books in the background with progress indicators.
• Automatic opening of cloud-stored books as soon as downloading finishes.
• Two-way background reading position sync using the Kobo protocol to align progress across devices.
• Direct remote book deletion from the server with confirmation prompts.

Fixes

• Fixed dictionary lookup app detection on Android 11 and newer.
• Fixed catalog refreshes resetting local reading progress and download history.
• Fixed file deletion silently failing when folders were missing storage write permissions.
• Fixed connection setup retrying over HTTPS when plain HTTP was explicitly selected for local servers without certificates.
• Reduced bookmark ribbon size so it no longer obstructs page text.

Under the hood

• Encrypted storage for calibre-web passwords and session sync tokens using the Android Keystore.
