1. Understanding the 3 Bottom Tabs: Bookshelf, Store, Profile

The bottom navigation bar provides three core destinations:

• 📚 Bookshelf: Your personal sanctuary. Switch between 3D Bookshelf and Clean List views, organize by folders, and draft your own Markdown columns;
• 🏬 Store: Featured literature selections and book discovery to explore new reads;
• 👤 Profile: Track reading time analytics, access the Help Center, connect cloud drives for serial auto-sync, and manage full backups.

2. How to Add Your First Book

2.1 In-App File Picker Import

1. Open BookFun and go to the bottom Bookshelf tab;
   
2. Tap the ”+” button in the top-right corner;
3. Select your downloaded eBook files (single or multiple files at once);
4. Tap “Open”. Within seconds, BookFun parses chapters, generates a beautiful cover, and places the new book at the top of your bookshelf.

2.2 Direct Share Import from External Apps

You can also long-press eBook files in the system “Files” app, messaging apps, or browsers to import directly via the system Share sheet:

• Long-press in Files App: Locate the book in the iOS Files app, long-press the file, tap Share, and select BookFun;
• Safari or Chat Apps: When downloading an eBook in Safari or receiving a book file in chat apps, tap the share icon and pick “Open in Another App” -> BookFun;
• AirDrop: Transfer eBooks via AirDrop from a Mac or another iPhone/iPad and choose BookFun on the incoming prompt;
• iPad Drag & Drop: Open the Files app in Split View, drag the eBook directly into the BookFun bookshelf, and release.

2.3 Supported eBook Formats

BookFun natively supports all major reading formats:

• TXT: Plain text novels with automatic encoding detection (zero garbled text) and intelligent chapter splitting. Multi-million-word files load instantly with zero lag;
• EPUB: Modern publication standard with rich typography, embedded styles, tables of contents, and illustrations;
• MOBI / AZW3: Classic Kindle formats for pristine reading;
• Markdown (.md): Ideal for technical notes and serial writings with code syntax highlighting and tables.

3. Handling Duplicate Book Imports

When importing a book with the same name as one already on your shelf, BookFun provides friendly options:

• Keep Both (Recommended): Appends a number (e.g. Three-Body (1)), keeping both editions independent;
• Replace Existing Book: Updates the file while fully preserving your current reading progress, bookmarks, highlights, and notes;
• Skip This Book: Discards the duplicate. Check “Remember My Choice” to auto-skip duplicates when importing in bulk;
• Corrupted File Detection: Zero-byte or incomplete downloads are caught immediately with an alert to prevent shelf clutter.

4. Opening Books & Smooth Page Turning

Tap any book cover on your shelf to enter the immersive reader.

4.1 3×3 Grid Gestures & Customizable Touch Zones

During reading, the screen is divided into an intuitive 3×3 grid of touch zones, making single-handed reading effortless:

Default Gestures:

• Left Zones (Top-Left / Mid-Left / Bottom-Left): Previous page (or swipe right);
• Right Zones (Top-Right / Mid-Right / Bottom-Right): Next page (or swipe left);
• Center Zone: Show / hide reading control menus.

Customizing Touch Actions:

In Reader Settings → Page Turning & Gestures / Touch Zones, you can configure custom single-tap actions for each of the 9 zones:

• 📖 Navigation & Jumps: Previous/Next Page, Previous/Next Chapter, Chapter Start/End;
• 🧭 Controls: Menu, Table of Contents, Full-Text Search, Exit Reader;
• 🛠️ Reading Tools: Add Bookmark, Create Note, Quick Audio TTS.

4.2 Appearance & Typography Settings

Tap the screen center to summon the menu for quick personalization:

• 📑 Contents & Notes: Browse full chapter tree, jump to target chapters, and view highlights and thoughts;
• Aa Font & Layout: Resize fonts (12–32 pt), adjust line and letter spacing, and pick your favorite typeface;
• 🎨 Eye-Care Themes: One-tap switch between Parchment (soft nostalgia), Eye-Care Green (relaxing for long sessions), Night OLED Pure Black (energy-saving & comfortable), or Paper White;
• 🔄 Page Transitions: Choose between crisp “Horizontal Slide” or layered “Horizontal Flip” page transitions.

5. Activating TTS Narration & Floating Capsule

Tired eyes? Switch to audio narration at any time:

1. One-Tap Audio Launch: Tap the screen center to summon the menu, then tap the prominent orange headphone icon 🎧 on the right to start voice reading immediately;
2. Smooth Follow-Along Highlighting: The currently spoken sentence is subtly highlighted, and the viewport glides gently to keep the active line comfortably centered;
   
3. Draggable Mini Floating Capsule:
   • Switching to the bookshelf or other tabs reveals a compact floating audio capsule;
   • Drag it anywhere on screen. Releasing it causes it to snap neatly to the nearest edge without obstructing buttons;
   • Tap the outer ring to play/pause, or tap the center to expand the full audio player console.
     

6. Beginner FAQ Quick Lookup

• Q: Why hasn’t my imported book appeared on the shelf?
  A: Pull down on the shelf list to refresh. For massive TXT epics, chapter splitting takes 1–20 seconds in the background.
• Q: Will TXT files show garbled text?
  A: BookFun embeds an automatic encoding recognition engine (UTF-8, GB18030, GBK, etc.) for instant, zero-configuration reading.
• Q: Why does audio stop when the screen locks?
  A: Check if “Low Power Mode” is enabled on iOS, and verify that “Background App Refresh” is enabled in iOS Settings → BookFun.
