🔥 Why Use This App Store Scraper?

Let US founders spend millions validating an app idea, finding product-market fit, and educating the market. Your job is simpler: find their gaps, localize the concept, and dominate your market faster.

• 🎯 Find Geo-Arbitrage Gaps: Discover apps making serious money in the US but lacking French, German, Spanish, or Japanese localization.
• 💡 Validate Demand Instantly: Scrape reviews from your target country and find users explicitly asking for translations or missing features.
• 📊 App Store Optimization (ASO): Extract competitor pricing, ratings, categories, and metadata across 175+ countries.
• ⚡ No Apple API Key Needed: Uses public Apple endpoints. No Developer API setup, no token management.

Unlike generic App Store scrapers, this Actor is built for App Store arbitrage, localization research, competitor analysis, and fast SaaS validation.

🧩 Use Cases

1. Find US apps to localize for France, Germany, or Spain

You search a niche in the US App Store, enable checkLanguage, and instantly spot winners that do not support your target market. Then you switch to Reviews mode to confirm users are complaining about missing localization.

2. Validate a micro-SaaS idea before you code

You already found a promising competitor. Paste its App ID, scrape reviews from your target country, and filter keywords like traduction, english, language, or bug. If the same complaint repeats, you have a much stronger build signal than a guess or a fake waitlist.

3. Track competitor feedback automatically

Add a list of App IDs to your workflow, schedule repeated runs, and push the output to Airtable, Google Sheets, Slack, or your LLM stack. This lets you monitor feature requests, onboarding friction, and localization pain over time.

🛠️ Quick Start: The Geo-Arbitrage Playbook

Want to find popular US apps that are missing a French, German, or Spanish translation? Use this 60-second flow:

1. Search the US App Store with country: "us" and a niche keyword.
2. Enable Language Check with checkLanguage: "fr" (or de, es, etc.).
3. Spot winners with high ratings and lots of reviews.
4. Switch to Reviews mode for the best candidates.
5. Pull country-specific reviews using reviewCountry: "fr".
6. Filter keywords like traduction, français, english, translate.
7. Build only if complaints repeat.

Result: a shortlist of successful US apps where local users are actively asking for a localized alternative.

🔬 Reviews Mode: Validate Demand Before You Code

If you only use one feature, use this one.

This is the highest-conversion workflow in the Actor because it answers one brutal question fast:

"Are users in my target country explicitly telling me what is missing?"

Instead of scraping broad market data, Reviews mode lets you test one concrete hypothesis:

"Do users in a target country explicitly complain that this successful app is missing local language support or key features?"

Real example from the demo

The video uses Remente: Self Care & Wellbeing (961633456) and forces review extraction from the French App Store.

Input:

{
  "mode": "reviews",
  "appIds": ["961633456"],
  "reviewCountry": "fr",
  "reviewPages": 3,
  "filterKeywords": ["traduction", "anglais"]
}

Example output:

{
  "appId": "961633456",
  "appName": "Remente: Self Care & Wellbeing",
  "country": "fr",
  "totalReviewsFetched": 10,
  "matchingReviewCount": 2,
  "filterKeywords": ["traduction", "anglais"],
  "reviews": [
    {
      "title": "Bien mais manque une chose",
      "content": "Manque la traduction en français",
      "rating": 3,
      "author": "NeTy81",
      "matchedKeyword": "traduction"
    }
  ]
}

That is not a vague signal. That is a real user telling you exactly what is missing.

🔌 Integrations and Automation

Because this Actor runs on Apify, you can connect it directly to:

• Make.com or Zapier for scheduled monitoring and alerts
• n8n for AI-assisted workflows and downstream enrichment
• Airtable or Google Sheets for competitor tracking databases
• Slack or Discord for automatic opportunity alerts

Typical automation ideas:

• weekly review monitoring for a watchlist of apps
• localization gap tracker by niche
• AI summarizer that turns reviews into product ideas
• competitor feed for product and growth teams

🤖 AI Agent Integration via MCP

Want AI agents to find app ideas for you?

Use the Apify MCP integration docs to expose this Actor directly to Claude, Cursor, or your own agents. They can run prompts like:

• "Find US habit tracker apps that do not support German"
• "Pull French reviews for the top meditation apps and isolate localization complaints"
• "Summarize feature requests from 3-star reviews for this competitor set"

You can also combine this Actor with Apify datasets and downstream LLM analysis for automated idea scoring.

⚠️ Known Limitations

• 500 reviews per country limit: Apple public review pagination tops out at roughly 10 pages, or about 500 reviews per app per country.
• Public endpoint constraints: Review freshness and completeness depend on what Apple exposes publicly.
• Localization detection is interface-level: If an app partially localizes content but not the full product experience, you still need to inspect the reviews manually.

❓ Frequently Asked Questions (FAQ)

Is this App Store scraper free to use?
