Adjust font size, line spacing, font family, and margins to find your perfect setup. Switch between paginated mode with page-turn animation, or smooth continuous scroll.

Verdict
The clearest difference is ads: Librai at none against ArcReader's shown. Librai also leads on update cadence (every 2 days vs every 6 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
