App Store Change Monitor
Tracks apps on the Apple App Store between runs (state kept in a named key-value store) and reports: new version + release notes,
price change, rating drop (configurable threshold), rating-count change, description/name/screenshot-count changes, and new reviews.
Data comes from Apple's public iTunes Lookup API and customer-reviews RSS (no key). Throttled to about 19 calls/minute.
Output: one app-snapshot row per app/country when it is a first-run baseline or has changed (with a changes list and alerts); unchanged apps and not-found apps are counted in the run's SUMMARY (key-value store), not the dataset, so you only pay for news (set emitUnchanged for a row every run),
plus one new-review row per unseen review. Image URLs are returned as links only.
Input example: {"apps":["https://apps.apple.com/us/app/instagram/id389801252","com.spotify.client"],"countries":["us","gb"],"maxReviewPages":2}
Limits: Apple's review feed holds roughly 500 recent reviews per storefront; first run only records a baseline; optional chart-rank tracking (trackRanks: free/paid/grossing; position in Apple's public top-200 charts, overall and in the app's primary category, with the previous run's ranks alongside) so run history builds a rank timeline.
Not affiliated with Apple.
Dev
npm i && npm test (stubbed HTTP). Live smoke test: see git history / run lib.run with an in-memory store.
Errors: if Apple is unreachable or rate-limiting after retries the run fails with a clear message (it never reports an outage as "not found"); apps that succeeded are still saved. Invalid entries in apps are logged as warnings, and the run fails if none is valid. Duplicate apps/countries are collapsed.
