[ Tailored to Your Eyes: Complete Customization ]
- Bring Your Own Fonts: Import and select external font files (.ttf / .otf) for EPUB and TXT books to create your ideal typography.
- Custom Themes & Contrast Guidance: Design your own reading themes with custom background and text colors, complete with smart contrast guidance to keep your eyes comfortable.
- Precision Layout Controls: Fine-tune font size, line spacing, paragraph spacing, and top/bottom/side margins down to the smallest detail.

[ Hands-Free Page Turning: Volume Buttons & Bluetooth Remotes ]
- Volume Button Navigation: Effortlessly flip pages one-handed using your device's side volume buttons (+/-). Easily toggle this option on or off in Settings.
- Bluetooth Remote & Page Turner Support: Prop your iPad or iPhone on a stand and turn pages remotely from under a cozy blanket without ever touching the screen.

[ Give Your Eyes a Break with Built-In TTS (Text-to-Speech) ]
- Commuting or resting your eyes in bed? Switch seamlessly to TTS mode and listen to your books like an audiobook.
