What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• app_tracker_lookup

  Use this when the user asks about one competitor app, such as "how many installs does this Play app have?" or "when was this app last updated?". It returns no reviews or complaint themes (no allowed source carries store reviews): for complaints, ask the user to paste the reviews.

• app_tracker_keywords

  Off: always answers source_off. App Store search results and suggestions sit under robots.txt Disallow lines on apps.apple.com, search.itunes.apple.com and itunes.apple.com, so they are not read. Say that search results are not available from an allowed source, and offer app_trac

• app_tracker_abandoned

  Off: always answers source_off. The scan behind it reads App Store search results, search suggestions, reviews and HTML chart pages, which robots.txt or Apple's terms do not allow, so it does not run. Say that this scan is off, and offer app_tracker_opportunities, whose stale fla

• app_tracker_keyword_rank

  Use this when the user asks where an App Store app ranks for search phrases by country, or how much demand or competition a phrase has. Pass app (id or link), keywords (1 to 20) and countries (up to 10, default us). Per keyword and country: rank is the app's place in the iTunes S

• app_tracker_publisher

  Use this when the user asks how many downloads a developer's apps get together, such as "how many downloads do PlaySimple's apps get?". Pass app (any App Store app of the developer) or developer (the App Store developer id). Returns every app of that developer, up to 60 by rating

• submit_feedback

  Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, i

• get_feedback_reply
