# Bookzy App vs Stackd

The clearest difference is in-app purchases: Bookzy App at none against Stackd's 1. Bookzy App also leads on ratings volume (28 vs 2). Stackd's advantage is update cadence (every 2 days vs every 3 months). On price, rating, review sentiment and ads there is nothing between them.
