# Calibre View vs Athene Reader

The clearest difference is rating: Calibre View at 5.0 against Athene Reader's 4.3. Athene Reader's advantage is update cadence (every 2 days vs every 6 weeks) and review sentiment (80% vs 67%). On price, ratings volume, ads and in-app purchases there is nothing between them.
