Google Play App Rating & Metadata Tracker

Track Google Play apps by package name and see what changed since your last run: star rating, rating count, the 1–5 star histogram, installs band, price, last update date and the ads / in-app purchase flags. Schedule it daily or weekly for ASO monitoring of your own apps and your competitors.

Aggregate data only. No reviews, no reviewer names, no developer names or contact details, no descriptions.

Quick start: example input, output and cost

Input:

{ "apps": ["org.wikipedia", "https://play.google.com/store/apps/details?id=com.spotify.music"], "country": "us" }

Output (one item per app, shortened):

{ "appId": "org.wikipedia", "name": "Wikipedia", "country": "us", "rating": 4.343, "ratingCount": 693988,
  "starHistogram": {"5": 460806, "4": 70621, "3": 27462, "2": 24845, "1": 57105},
  "installs": "50M+", "installsMin": 50000000, "price": 0, "currency": "USD", "updatedOn": "Oct 5, 2026",
  "containsAds": false, "inAppPurchases": false, "status": "changed", "ratingDelta": -0.002, "ratingCountDelta": 412,
  "changes": [{"field": "ratingCount", "from": 693576, "to": 693988}] }

Cost: 2 apps = $0.0006. 100 apps checked daily for a month = about $0.90.

What you get

• appId, name, country, url, category, contentRating, iconUrl
• rating (3 decimals), ratingCount, starHistogram (count per star)
• installs (Google's band, e.g. 1M+) and installsMin (number)
• price, currency, free, containsAds, inAppPurchases, updatedOn
• With Compare with the previous run (on by default): status (baseline / changed / unchanged), changes[] (field, from, to), ratingDelta, ratingCountDelta, previousCheckAt

Snapshots are kept per app and country in a named key-value store (monitorName), so you can run separate sets such as my-apps and competitors.

Input

Field	Default	Meaning
apps	(required)	Package names or Google Play app links, up to 1000 per run
country	us	Play Store country (price, currency, availability follow it); pages are read in English
trackChanges	true	Compare with the previous run and report changes
monitorName	default	Name of the snapshot set

Pricing

Event	Price
App checked (rating + metadata saved)	$0.0003

No start fee. Invalid package names, apps that do not exist in the chosen country, blocked or unreadable pages are free and listed in the ERRORS record with the reason. Set a maximum cost per run and the actor stops before it is reached.

What this actor does not do

• No Play search, top charts, reviews or data-safety pages: Google Play's robots.txt disallows those paths, and we follow it.
• No Apple App Store: Apple's website terms forbid robots and its Search API is limited to promoting store content.
• No proxies, no cookies, no login, no CAPTCHA solving. If Google Play refuses a request, the app is reported as failed (free).

Responsible use and compliance

• Only public app detail pages (/store/apps/details), which play.google.com/robots.txt allows. robots.txt is checked for every request (fail-closed). Google's Terms of Service restrict automated access that violates robots.txt instructions; this actor never does that.
• Honest User-Agent with a contact URL, at most 1 request per second, Retry-After honoured.
• No personal data: Google marks app developers as schema.org Person, so developer names, emails, phones and addresses are never extracted; neither are reviews or descriptions.
• App names, icons and ratings belong to their owners and Google. Use the data for analysis and monitoring.

Use it in n8n, Make or Zapier

Schedule the actor daily, then filter dataset items on status = "changed" (or ratingDelta < -0.05) and send an alert.
