Data source: Kaggle Google Play Store Dataset. This dataset includes 10,840 apps across 33 categories. The analysis focuses on category-level differences in supply (app count), perceived quality (rating), and demand (installs).
App supply is highly concentrated. Family and Game dominate in volume, while most categories remain significantly smaller. This reflects where developers compete, not necessarily where users concentrate.
Ratings are tightly clustered between 4.0 and 4.4. Events and Education rank highest, while Tools and Dating lag behind, suggesting that saturation may reduce average quality.
User attention is highly uneven. Game and Communication dominate installs, indicating a winner-take-all dynamic where a small number of apps capture most users.
Across categories, supply, quality, and demand are misaligned. High app counts do not translate into high user adoption. Instead, user attention concentrates in a few categories driven by dominant apps, while crowded categories fragment demand.
