High-Demand Low-Rating App Category Opportunity Scan

A ranked league table of 64 app-store categories scored by demand vs. user dissatisfaction — where download volume is high but ratings are weak — with 348 representative high-demand low-rated apps as concrete build targets, for both Apple App Store and Google Play.

Part of the DataForge Open Data program — full production packages, free for academic and personal use. Canonical dataset page: https://data.zalize.com/datasets/app-category-opportunity-scan
