Reading comfort is personal. What works for one person might strain another’s eyes. That’s why Lion Reader gives you comprehensive control over how your content appears, letting you create the perfect reading environment for your preferences and lighting conditions.

Dark Mode

Full dark mode support comes powered by next-themes. You can follow your system’s light/dark preference or manually toggle between modes. Every component, from the sidebar to article content, adapts seamlessly to your chosen theme.

Typography Controls

Fine-tune your reading experience with multiple font families to choose from:

• System — Uses your operating system’s default font
• Serif options — Merriweather and Literata for traditional book-like reading
• Sans-serif options — Inter and Source Sans for modern, clean typography

Text size options range from small to extra-large, with responsive scaling across all screen sizes. Choose left-aligned or justified text alignment based on your preference. All settings save locally and apply instantly as you adjust them.

Progressive Web App

Lion Reader is a Progressive Web App, which means you can install it on your desktop or mobile device for a native app-like experience. On mobile, the app locks to portrait orientation for optimal reading comfort. The demo page you’re viewing right now showcases the reading experience with all these customization options available.
