Portfolio dossier
A full-portfolio read across all 51 tracked apps — maintenance cadence, reach, localization and how old the catalogue is. Computed live from public listing metadata; downloads, revenue and retention are not visible to us and are not estimated.

Publishing behaviour
The catalogue’s attention is unevenly distributed. The single most-rated app holds 13% of the 54 ratings observed across 51 loaded listings, and the top three hold 28%. That is a portfolio led by a small flagship set rather than an even bench.
Roughly 22 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 Stickers — a focused publisher rather than a diversified one.
Portfolio
Spread across 10 categories. Bar length shows each category’s share of observed ratings; the app count beside it exposes where volume and audience diverge.
