Publishing behaviour
The catalogue’s attention is unevenly distributed. The single most-rated app holds 25% of the 4 ratings observed across 54 loaded listings, and the top three hold 75%. That is a portfolio led by a small flagship set rather than an even bench.
Roughly 4 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 Productivity — 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.
