Public app data from the Apple App Store and Google Play in one clean schema: title, developer company, price, ratings and histogram, installs, version, release notes, Google Play reviews and Apple top charts. For app-market research and competitor tracking.
First release: App Store (Apple Lookup API) and Google Play (public app page) app records in one schema, per country.
Google Play: rating histogram, installs, written-review count, ads / in-app purchase info, and up to 20 reviews per app with developer replies — no reviewer names, avatars or ids; reviewer names removed from replies; emails and phone numbers redacted.
Apple top free / top paid charts (up to 100 ranks per country), optionally with full app records for charted apps.
robots.txt checked live on every run (bundled snapshot when a host's robots.txt is unreachable); App Store keyword search, App Store reviews, Google Play search and Google Play full review history are not supported because the stores' robots.txt disallow them.
Polite fetching: Apple's documented ~20 calls/minute, ~1 Google Play page per second, retries with backoff; SSRF-safe fetching restricted to the three store hosts; response size caps; uncharged error rows; maxItems and cost-limit stops.
