FBReader: Favorite Book Reader

What is FBReader?

FBReader (Favorite Book Reader) is a free Android application designed to let you read digital books comfortably on smartphones, tablets, and e‑ink devices. It focuses on speed, low resource usage, and a high degree of personalization, making it a solid choice for anyone who wants a straightforward reading experience without unnecessary bloat.

Main features

• Broad format support – FBReader can open ePub, PDF, Kindle azw3, fb2 (including zipped versions), comic book archives (CBZ/CBR), as well as plain text, HTML, DOC and RTF files.
• Customizable appearance – Choose your own TrueType or OpenType fonts, switch between day and night themes, and adjust screen brightness with a swipe gesture.
• Layout control – Fine‑tune margins, line spacing, and paragraph indentation to match your reading preferences.
• Gesture support – Navigate pages, adjust settings, and invoke menus using intuitive swipe and tap gestures.
• Dictionary integration – When you tap a word, FBReader can launch your preferred dictionary app for instant look‑ups, which is handy for language learners.
• Library management – The app scans the device’s Books folder automatically and also lets you browse online catalogs via built‑in OPDS support.
• Multi‑language interface – The UI is localized into dozens of languages and includes hyphenation patterns for many of them.

How it works

After installation, FBReader scans the default Books directory on your device and adds any supported files to its library view. You can also add books manually by placing them in that folder or by using the built‑in catalog browser to download titles from OPDS sources. When you open a book, the reader renders the content using the selected theme and font, and you can swipe along the screen edge to adjust brightness without leaving the reading view.

Practical uses

• Daily reading – Whether you prefer novels, technical manuals, or comic books, FBReader handles them all in a single, lightweight app.
• Language study – The quick dictionary lookup and support for multiple languages make it useful for learners who need to reference words on the fly.
• E‑ink devices – Optimized rendering ensures smooth performance on e‑ink readers that run Android, extending battery life while preserving readability.

Installation information

FBReader is available as a free download from the Google Play Store. The package name is org.geometerplus.zlibrary.ui.android. No additional permissions beyond standard storage access are required to read files stored on your device.

Compatibility

The app runs on Android devices that meet the minimum system requirements for standard Play Store apps. It adapts its interface for both small phone screens and larger tablets, and it includes specific optimizations for e‑ink displays.

Things to know before installing
