Tools of App Store Opportunity Tracker
	Description		Read-only	Idempotent	Open world
`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 flag marks chart apps with no update for over 180 days.	Off: always answers source_off.

Pass country, chart (free or paid) and limit. Returns ranked entries with price, rating, rating count and change since an earlier snapshot, plus movers (gainers, losers, new entries, dropped) and apps released in the last 7 days. movers.since is the time of the snapshot compared against; null means there is none yet. Google Play, grossing and genre charts answer source_off: no allowed source publishes them.

`app_tracker_estimate`Use this when the user asks how many downloads an App Store app gets, such as "how many downloads does Daily Themed Crossword get a month?". Pass app (an App Store id or link). Returns downloads30d, a range (low, high, ratio) with method (rank_curve, rank_and_velocity, rating_velocity or rank_bound), confidence and basis lines, plus download growth over 7, 30 and 90 days (null until the history is that long). revenue30d is null and warnings says why: the grossing chart has no allowed source. Worldwide App Store, last 30 days. rank_bound means only an upper bound is known.

`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 Search API's top 200 (not_ranked past it, never guessed); volume 0-100 is the top 50 names' match to the phrase (whole phrase 1, else half the word share), summed over 50; difficulty 0-100 is the top 10 rating counts on a log scale (10 ratings 0, a million 1), summed over 10; weakMarket: not ranked while 10 other apps are. fetchedAt is the read time. A call waits about 8 s; cells not read by then are pending and keep being read: call again after retryAfterSeconds while pending falls. warnings says why reads fail.

`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. Pass app (an App Store id or link, or a Google Play package or link) and country, or apps (up to 5) to compare in one call. Returns the price, rating, rating count, update date, an estimate and a Stale Winner score; for Google Play also exact installs, the rating split and the in-app price range. warnings names each part that is off: App Store IAP tiers, version history and privacy labels. With apps, the answer is reports (one per app, in the order asked) and failed (each app not read, with its error code).

`app_tracker_opportunities`Use this when the user wants app ideas or weak incumbents on a top chart, such as "which popular apps on the top free chart are badly rated or abandoned?". Pass the chart inputs and min_score. Scans all 100 chart apps and returns each with a Stale Winner score (0 to 100, 75 or more is high), its reasons, flags (low_rating, stale) and a download and revenue estimate range. Scores rank opportunities; they do not prove a market.
