Publishing behaviour
The catalogue’s attention is unevenly distributed. The single most-rated app holds 49% of the 1,885 ratings observed across 11 loaded listings, and the top three hold 98%. 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. Both the largest cluster of apps and the bulk of the ratings sit in Utilities — 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.
