If your app isn’t found, it gets left behind.

People search the App Store every day for apps like yours. But if your app doesn’t rank for the words they use, they find a competitor instead.

FAQ

Frequently asked questions

iOS developers and app teams who want more installs from App Store search. Indie developers use it to choose the keywords for their listing. Studios and marketers use it to compare countries, watch competitors, and track rankings over time.

No. Each keyword gets an Opportunity score that weighs how many people search for it against how hard it is to rank for, and Relevancy shows how well it fits your app. Start with the keywords that score well on both, then track how your rankings move. You can also connect Claude Code, Codex, or Cursor through MCP and let your AI agent do the research.

  • Rankings, top apps, and ratings: The App Store itself. Asonix searches it in each country and records where every app ranks.
  • Keyword popularity: Apple’s own Search Ads score for every keyword Apple rates, and Asonix’s machine‑learning models for the rest.
  • Top Advertisers: The ads in App Store search.
  • Competitors’ Meta ads: Meta’s Ad Library.
  • Download and revenue estimates: Approximate. Use them to compare apps, not as exact figures.

  • When Apple has a score: Asonix extracts Apple’s own popularity value directly from Apple Search Ads. It is not an Asonix estimate. That even includes keywords Apple’s official API leaves out, since it only returns the top 500 searches per category.
  • When Apple returns only a 5: Since October 2025, Apple returns its minimum score of 5 for keywords below a country-specific cutoff (about 39 in the US). A 5 therefore no longer reveals the keyword’s actual popularity. For these keywords, Asonix’s machine‑learning models estimate popularity from dozens of current App Store signals.
  • In countries without Apple Search Ads: Apple provides no keyword popularity data there, so Asonix estimates popularity using the same models.

No. Asonix works from public App Store data. You sign in with Google and add any app, your own or a competitor’s, without giving Asonix access to your developer account.

Apple’s App Store: iPhone, iPad, and Mac apps in all 175 storefronts. Google Play is not supported. Apple’s popularity score exists only where Apple Search Ads runs; in other countries, popularity is Asonix’s estimate.

Asonix checks your tracked keywords every day in every country you track.

Put your strongest keywords in your app’s name, subtitle, and keyword field, where they count most for search. Track them in Asonix, ship your update, and watch which rankings move. Keep what works and replace what doesn’t with each release.

The apps that appear in App Store search ads for a keyword, country by country, and how often each one appeared in the last seven days. Apps keep paying for a keyword when it brings them users, so advertisers are a sign the keyword is worth winning.

People now ask AI assistants which app to download. Every week, Asonix asks ChatGPT the kinds of questions your users ask and shows whether ChatGPT recommends your app, mentions it, or leaves it out. You also see which apps it picks instead, why it recommends each one, which of those reasons your App Store description is missing, and which sites it read before answering.

Yes. Asonix has an MCP server, so Claude Code, Codex, Cursor, and other MCP clients can research keywords, check rankings, and add keywords to your workspace for you. The MCP setup guide shows how to connect it.

  • Every App Store country: Popularity for all 175 storefronts, including Serbia and 80+ other countries where Apple Search Ads doesn’t run.
  • Every keyword in English: Hover a keyword in any language to read it in English, powered by Google Translate.
  • Top Advertisers: See which apps run Apple Search Ads on each keyword, in each country.
  • AI Visibility: See whether ChatGPT recommends your app, which apps it picks instead, and why, so you know what to change to get recommended more.
  • Works on any device: Asonix is a web app, so you can use it in any browser, including on your phone, unlike ASO tools that only run as a Mac app.
  • Unlimited for $99/year: Track as many apps and keywords as you want, with everything above, plus competitors’ Meta ads and an MCP server for AI agents.

Asonix Pro costs $99/year and includes unlimited apps and unlimited keywords. There is no free plan.
