App Store Listing and Ratings

App Store listing data for any app on any storefront: current and all-time star ratings with review counts, version, release notes, size, price, content rating, genres and release dates. Includes a version-sentiment read comparing the current version's rating against its all-time average, which is how you spot a release that damaged an app. Look up by numeric App Store id or search by name.
