Publishing behaviour

The catalogue’s attention is unevenly distributed. The single most-rated app holds 76% of the 1,180 ratings observed across 6 loaded listings, and the top three hold 92%. That is a portfolio led by a small flagship set rather than an even bench.

Roughly 3 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 Productivity — a focused publisher rather than a diversified one.
