Find app ideas - niches ranked by opportunity score (demand, weak incumbents, competition, monetization, trend).

Use this when a user wants to know what app to build, or how attractive a niche is. Every niche of the App Store and Google Play (an AI taxonomy of the catalog, e.g. "ADHD habit tracker") is scored weekly from 0 to 100 per store and country: demand (30%: popularity of the niche's search keywords + ratings the niche holds), supply_gap (30%: incumbents' rating, apps not updated for a year, a fragmented market, unhappy reviews), competition (20%: ease, from keyword difficulty and the number of apps with 100k+ ratings), monetization (10%: incumbents selling IAP / paid, top-grossing chart presence) and trend (10%: ratings growth, share won by apps released in the last 2 years). Every component lists its signals with the raw values; a signal without data is left out and confidence (0–1) drops. Each item has the niche's top keywords (popularity, difficulty), its incumbents and their complaints from AI-tagged reviews; the top 10 per store in the US also carry an analyst headline and thesis. Filter by niche (id, slug or words like habit tracker) or category; page with cursor. Then use GET /v1/keywords on top_keywords and GET /v1/apps/{app} on incumbents to dig deeper. A page with no results costs nothing.
