AppCorpus is an evidence-first catalog designed to help people and AI agents find and compare mobile apps. Its database covers more than 48,000 current apps, searchable by task, function, price, platform, and freshness. Users can explore popular needs, such as planning a trip or tracking expenses, or browse a wide range of categories, including productivity, education, health and fitness, travel, finance, entertainment, and utilities.

For each app, AppCorpus brings together structured information such as features, prices, screenshots, reviews, ratings, and data freshness. The company says it parses app stores, enriches listings with structured knowledge, and publishes entries that meet its quality standards. Its catalog includes apps for iPhone, iPad, Mac, Apple Watch, and Android, with details and links to open individual listings.

AppCorpus also offers an MCP endpoint that lets AI agents query the catalog for app searches, details, and taxonomy as structured data. The service publishes information about its methodology, coverage, data sources, and privacy, helping users assess how its listings are assembled and maintained.
