Publishing behaviour

The catalogue’s attention is unevenly distributed. The single most-rated app holds 66% of the 32 ratings observed across 9 loaded listings, and the top three hold 97%. That is a portfolio led by a small flagship set rather than an even bench.

Roughly 2 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 Games, yet earns the most ratings in Education — volume and audience sit in different places.

Portfolio

Spread across 5 categories. Bar length shows each category’s share of observed ratings; the app count beside it exposes where volume and audience diverge.
