App Store Intelligence — Apps, Top Charts, Reviews & Rank Monitoring

One Actor for Apple App Store research and monitoring, built on Apple's official public APIs (iTunes Search & Lookup API and Apple's RSS feeds) — no browser, no login, no fragile HTML scraping.

Four modes:

1. Search — apps for any keyword in any country, with their search position.
2. App details — 30+ fields per app from a URL, numeric ID or bundle ID: rating, rating count, current-version rating, price, version, release dates, size, genre, languages, developer, icon and screenshots.
3. Top charts — top free / paid / grossing by country, optionally per genre (Games, Business, Finance…).
4. Reviews — the most recent reviews per app and country (rating, title, text, app version, date). Reviewer identities are not collected.

Monitoring mode (schedule daily or hourly) outputs only what changed: apps entering, leaving or moving in a chart, version releases, price changes, rating moves, and new reviews. Great for ASO agencies, mobile studios, investors and competitor tracking.

Input examples

Top 100 free apps in 3 countries:

{ "mode": "charts", "chartType": "top-free", "countries": ["us", "gb", "fr"], "maxItems": 100 }

Daily rank tracking of the Finance top grossing chart:

{ "mode": "charts", "chartType": "top-grossing", "genreId": 6015, "countries": ["us"], "maxItems": 200, "monitorMode": true, "monitorId": "finance-us" }

Competitor watch (new versions, price & rating changes):

{ "mode": "apps", "apps": ["https://apps.apple.com/us/app/notion/id1232780281", "com.spotify.client"], "countries": ["us"], "monitorMode": true }

New reviews only:

{ "mode": "reviews", "apps": ["1232780281"], "countries": ["us", "gb"], "monitorMode": true }

Output (app)

{ "type": "app", "country": "us", "appId": "1232780281", "bundleId": "notion.id", "name": "Notion: Notes, Tasks, AI",

  "currentVersionReleaseDate": "2026-09-24T15:02:11Z", "genre": "Productivity", "sizeMB": 142.3, "url": "https://apps.apple.com/…" }

Charts return rank, appId, name, developer, genre; in monitoring mode also changeType (entered / left / moved-up / moved-down), previousRank and rankChange.

Notes & limits

• Apple returns at most ~500 recent reviews per app and country, and up to 200 search results per keyword.
• Charts without a genre use Apple's Marketing Tools feed (top 100); genre charts use the classic RSS feed (top 200).
• Data comes from Apple's public APIs; use it in line with Apple's terms. No personal data is collected.
