# ARNBOOK vs Naiin Reader

The clearest difference is rating: Naiin Reader at 2.7 against ARNBOOK's 1.2. Naiin Reader also leads on in-app purchases (none vs 17). ARNBOOK's advantage is update cadence (every 3 weeks vs every 2 months) and review sentiment (42% vs 33%). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. ARNBOOK sells 17 one-off in-app purchases. Naiin Reader asks for nothing beyond the download.
