99 iPhone App Ideas That Could Make You Rich
The full list. Every idea ships on iOS, every one has a real-app precedent earning the benchmark revenue, and every one includes an honest build-cost estimate for a solo founder in 2026. Sorted by category — productivity, fitness, finance, social, learning, marketplace, travel, food, creator, AI novelty.
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.
