Publishing behaviour

The catalogue’s attention is unevenly distributed. The single most-rated app holds 50% of the 3,190 ratings observed across 17 loaded listings, and the top three hold 77%. That is a portfolio led by a small flagship set rather than an even bench.

Roughly 5 apps account for about 90% of the observed ratings; the rest form a long, light tail. We read that as a strategy signal, not a cadence number: the publisher lists the most apps in Education, yet earns the most ratings in Health & Fitness — volume and audience sit in different places.

Portfolio

Spread across 6 categories. Bar length shows each category’s share of observed ratings; the app count beside it exposes where volume and audience diverge.
