How this list is built

  • Market stats — search demand, category TAM, 2026 growth rate from public App Store data and Sensor Tower / AppFigures benchmarks.
  • Real-app precedents — 2–4 named apps in the same space with estimated monthly revenue. Honest ranges, not headlines.
  • Build cost — solo-founder cost using the MyAppTemplates boilerplate + Claude Code. Contrast column for agency delivery.
  • Monetisation fit — subscription, IAP, ads, or freemium — which actually works for the category.
