$500 to $10K/Month From Dead-Simple One-Feature Apps

  • Steve Young

  • App Builder (AppMasters.com)
  • $9,000 monthly from one app

📝 Steve Young recently broke down how he builds tiny single-feature apps around keywords the big players ignore…

First-time founders focus on features. Second-time founders focus on distribution.

The method: skip the brainstorm, start with search. Find an App Store keyword with real demand but few competitors, then build one app that does just that one thing.

Steve walks his talk 👇

  • JPEG-to-PDF converter – $500/mo
  • “Green noise” sleep app – $200-300/mo
  • AI paraphrasing app – $2,200-2,600/mo

Each app is named after the keyword it targets. No branding. And with AI coding tools, a simple utility takes 2-3 days to build.

The real lever is the paywall. Steve bought a frequency generator app charging a one-time $2.99, making almost nothing despite 100 downloads a day 👀

He added a paywall during onboarding and switched to a $60/year subscription…

$1–$2 to $8,000–$10,000 a month with no new features.

Same app. Same downloads. 🤯

Honest part: only about 40% of his launches make real money. Think singles, stack a few.

Pick one keyword a big app ignores and ship a tiny app for it 😎
