🌟 Core Highlights (v2.2 Upgrade)

  • Broad File Format Support: Seamlessly opens TXT, EPUB, MOBI, AZW3 (Kindle), DOCX, Markdown, and PDF eBooks and documents.
  • Unified Clean Layout: Automatically strips away conflicting web styles upon import and applies a polished publishing layout. Text and illustrations align gracefully with zero loading delay.
  • Refined Typography Details: Smart paragraph indentation, automated punctuation boundary adjustments, and balanced margins deliver a soothing reading journey.

2. Smart Proofreading with Instant Layout Refresh

  • Fix Typos on the Fly: Notice an OCR mistake, typo, or unwanted promotional text? Simply highlight the text to create a rule—the rule name is automatically filled for you.
  • Immediate Page Refresh: Saving a proofreading rule updates your current page in milliseconds—no need to exit and reopen the reader.
  • Dynamic Radar Scan: Running full-book proofreading displays a colorful radar animation alongside a real-time chapter progress bar, giving you clear visibility with no frozen screens.

3. 3-Dimensional Highlight Colors with Custom Themes

  • Dedicated Highlights for Every Purpose: Text selections, full-text search results, and audio playback highlights each use distinct colors that never conflict:
    • Text Selection: Automatically blends into your book theme (Parchment Brown, Eye-Care Bamboo Green, Deep Night Black, Classic Paper White);
    • Full-Text Search: High-contrast bright yellow to spot matching sentences instantly;
    • Audio Narration: Vibrant animated orange to clearly track the spoken sentence.
  • Custom Color Picker & One-Tap Reset: A new “Highlight Color Settings” panel in Preferences lets you freely choose your favorite shades or restore official defaults anytime.

4. Audio Narration Companion with Auto-Healing Reconnect

  • Lifelike AI Voices: Enjoy natural, emotive AI voices with male, female, and regional dialect options alongside standard system speech.
  • Floating Mini Player: Stays conveniently anchored to the screen edge as you browse your bookshelf or profile, allowing quick scrub, pause, and speed adjustments.
  • Seamless Reconnect Recovery: If an offline interruption temporarily drops you to local speech, BookFun automatically switches back to high-fidelity AI voices the moment your Wi-Fi or cellular connection restores.
  • Symmetric Control Bar: Symmetrical playback controls prevent awkward text wraps, and exiting audio narration instantly releases background network connections to preserve your phone’s battery.

5. Deep Bookshelf Search & Folder Organization

  • Search Across Folders: Search by title or author on your bookshelf to see all matching books laid out flat, ready to open in one tap without digging through subfolders.
  • Folder Badge Pills: Search results feature subtle badges (e.g., 📁 Sci-Fi) so you instantly know where each book lives, with batch selection, moving, and deletion.
  • 2x2 Visual Folders: Create custom bookshelf folders showing 4 mini cover previews to keep your library neatly organized.
  • Smart Cover Completion: Built-in online cover search lets you update your favorite novels with high-res art, automatically cropped to the golden 0.72 publishing ratio.
  • Select & Search: Tap “Search” directly from highlighted text to immediately initiate a full-book search for character names, clues, or plot points.
  • Multi-Keyword Filtering: Combine multiple search terms to pinpoint exact scenes across massive multi-volume epics in seconds.

7. Authentic Reading Time Analytics

  • Accurate De-Duplicated Time: Intelligently unites overlapping listening and reading intervals on the same book, ensuring your daily stats remain authentic and never artificially double-counted.
  • Reading Days Dashboard: The Profile tab now highlights your “Total Reading Days”, with direct one-tap navigation to your bookshelf.
  • Today’s Reading Treemap: Your daily reading is visualized as colorful building blocks—books you spent more time with occupy larger blocks for an intuitive daily review.

8. Cloud Drive Sync & Effortless Serial Follow-Up

  • Automatic Chapter Updates: Link with Baidu Netdisk or home NAS network shares to automatically pull newly appended chapters when web novels or serialized books update.
  • Connection Diagnostics: Easily test your cloud storage connection status with a single tap in the configuration panel and assign custom friendly names.

9. Pure Privacy & Fast Device Migration

  • 100% Local-First: Books, annotations, and reading progress remain strictly on your device without third-party tracking.
