App Store ASO Keyword Tool

Find out which apps rank for any App Store keyword, track where your own app ranks, and see how competitive each keyword is. This tool runs on Apple's public iTunes Search API, so it is fast and reliable, and needs no API key, no login, and no proxies. It gives app marketers the same kind of keyword intelligence that subscription tools charge $83 to $179 a month for, as clean pay-as-you-go data you can open in a spreadsheet. It is a pay-as-you-go App Store ASO keyword tool and rank tracker, and an affordable AppTweak and Sensor Tower alternative for people who want the data in a spreadsheet, not another subscription.

• Track App Store keyword rankings daily
• Find the top apps for any App Store keyword
• Score App Store keyword difficulty and opportunity
• Check where your app ranks for a keyword
• Export ASO keyword data to CSV, Excel, or JSON
• Pay as you go, no ASO subscription

Because it uses an official public API rather than fragile page scraping, there is nothing to break when a web page changes, which makes it dependable for daily rank tracking.

What it does

The App Store ASO Keyword Tool works in two modes. You give it a list of keywords and pick one of two actions. In "Top apps for keywords" mode it returns the top ranking apps for each keyword, plus a quick read on how popular, difficult, and worth targeting that keyword is. In "Track where apps rank" mode it tells you exactly where each app you care about sits in the search results for each keyword. Results export to CSV, Excel, or JSON like any Apify dataset.

Who it is for

• Indie app developers who want to track their app's keyword rankings daily without paying for a dashboard seat.
• ASO agencies benchmarking many client apps across many keywords on a schedule.
• Product marketers running a launch-week competitor scan to see who owns the keywords they want.
• Analysts and investors who want clean, flat keyword data to pipe into their own spreadsheets or BI tools.

Use cases

1. Keyword opportunity research. Run a set of candidate keywords and sort by the opportunity score to find the ones with real demand and beatable competition before you rewrite your app listing.
2. Daily rank tracking. Save your target keywords and schedule a daily run to watch your app climb or slip over time, then chart the history in a spreadsheet.
3. Competitor rank benchmarking. Track a group of competitor apps across your priority keywords to see who ranks above you and where you can overtake them.
4. Market sizing before you build. Scan a niche's keywords in seconds to gauge how crowded and how popular it is before committing to an app idea.

Two actions

Top apps for keywords

Returns one row per ranked app, for each keyword, with the app's rank, name, developer, rating, review count, price, and genre, plus keyword-level context: total results, the review-count scale of the top competitors, the average rating of the top apps, how many of the top apps are paid, and three directional scores (popularity, difficulty, opportunity) from 0 to 100.

Track where apps rank

Returns one row per app, for each keyword, showing the app's rank position (or a clear "out of top 200" flag), whether it is your app, and the app's rating, review count, price, genre, and developer.

About the scores

The popularity, difficulty, and opportunity numbers are directional prioritization aids from 0 to 100, worked out from the review counts and ratings of the top ranking apps. They are meant to help you sort and shortlist keywords quickly, not to serve as calibrated indexes. For important decisions, cross-check the raw columns like total results and top-10 median review count, and apply your own judgment.

Pricing

This tool uses pay per event pricing. You pay a small fee for each result row it returns, and nothing for keywords or apps that return no data. There is no monthly subscription. A typical daily rank check of one app across 20 keywords is only a few cents a day. Compare that to fixed monthly ASO subscriptions in the $83 to $179 range.

How it works

For each keyword, the App Store ASO Keyword Tool calls Apple's public iTunes Search API with the software filter, which returns apps in App Store ranking order for your chosen storefront. In "Top apps" mode it keeps the top apps you asked for and computes the keyword context. In "Track ranks" mode it looks up your chosen apps once for their details, then finds each app's position in the ranked results. A short delay runs between keywords to stay within Apple's public rate limits.

Frequently asked questions

Do I need an Apple developer account or API key?

No. The iTunes Search API is a public endpoint. This tool needs no key, no login, and no cookies.

Is it legal to use this data?

The tool reads only publicly available App Store metadata through Apple's official public API, the same information any visitor sees. As always, review the terms that apply to your specific use case.

How do I find an app's ID?

Open the app's App Store page. The ID is the number right after /id in the address, for example apps.apple.com/us/app/instagram/id389801252 has the ID 389801252.

What does "out of top 200" mean?

Apple's public search returns up to 200 apps per keyword. If your tracked
