Reader

A cozy, lightweight EPUB reader for Android, made for reading webnovels. Gruvbox dark theme with a pink accent, and a library laid out like a manga reader.

Features

• Library with cover grid, a "continue reading" card, unread-chapter badges, search and sorting
• Book page like a manga app: blurred cover header, description, chapter list with read markers, bookmarks
• Three reading modes
  • Infinite scroll: chapters load as you scroll
  • Paged: swipe or tap to slide between pages
  • Book flip: pages turn like a real book, and the page follows your finger
• Text settings: 7 bundled fonts (Literata, Merriweather, Lora, EB Garamond, Atkinson Hyperlegible, Nunito, OpenDyslexic) plus system fonts; size, line spacing, paragraph spacing, letter spacing, margins, justify, hyphenation, indent, bolder text
• Themes: Gruvbox Dark (default), Dark Hard, AMOLED, Gruvbox Light, Light Soft, with 7 Gruvbox accent colours (pink is the default)
• Tap zones (normal, inverted, next only, off), volume-key page turns, auto-scroll and auto page turn, brightness, keep screen on, fullscreen, page/clock status line
• Opens .epub files straight from a file manager or the "Share" menu

Install

Grab the latest Reader-*.apk from Releases, open it on your phone, and allow installing from unknown sources.

Build

Every push runs .github/workflows/build.yml, which builds a signed release APK and publishes it as a GitHub release.

Locally (requires the Android SDK):

./gradlew assembleRelease

The app is plain Android Java with no libraries and no WebView, so it stays light on RAM and CPU:

• Epub.java reads the EPUB straight from the zip (nothing is unpacked)
• Renderer.java turns chapter XHTML into styled text
• ReaderView.java draws pages with StaticLayout and handles scroll, slide and the 3D page flip
• MainActivity, BookActivity and ReaderActivity are the library, book page and reader screens, built in code by Ui.java and SettingsPanel.java
• Fonts live in app/src/main/assets/fonts (subset to Latin, Greek and Cyrillic)
