Publishing behaviour

The catalogue’s attention is unevenly distributed. The single most-rated app holds 24% of the 407 ratings observed across 14 loaded listings, and the top three hold 55%. That is a portfolio led by a small flagship set rather than an even bench.

Roughly 9 apps account for about 90% of the observed ratings; the rest form a long, light tail. Both the largest cluster of apps and the bulk of the ratings sit in Education — a focused publisher rather than a diversified one.

Portfolio

Spread across 3 categories. Bar length shows each category’s share of observed ratings; the app count beside it exposes where volume and audience diverge.
