//why this works

You no longer need to code or pay a developer.

AI design tools now build the entire look of an app from a single prompt, and AI coding agents turn that design into a working product for free. The second edge is distribution: skip the App Store (weeks of waiting plus a 30% Apple cut) and ship a web app instead. It is live the moment it is done, works on every phone and laptop through a browser, and every dollar stays yours.

//The workflow
Step · 3 steps

Design the app in Google Stitch

Sign up free at stitch.withgoogle.com, paste one prompt, and let Stitch build the entire design for you.

A full, professional app design, free. Tweak and regenerate until the layout feels right.

Step · 3 steps

Turn the design into code for free

Have an AI coding agent build the app from your Stitch design. Recommended: Antigravity (Google's coding agent, best design quality). Alternatives: Claude Code or ChatGPT Codex.

A working app without touching a single line of code yourself.

Step · 3 steps

Ship it and start charging

Deploy the web app (your coding agent will walk you through a free host), then put it behind a simple subscription starting at $9/month.

A live web app anyone can use from a browser, and income you keep 100% of.

Step 1: Design the app in Google Stitch

Sign up free at stitch.withgoogle.com, then paste one prompt and let Stitch build the entire design for you.

Paste into Google Stitch
Design a clean, modern mobile app for [your idea, e.g. a daily habit tracker]. Include a home screen, an add/create screen, a list/detail screen, and a settings screen. Use a simple, premium look with rounded cards and clear typography.

Output: a full, professional app design, free. Tweak the prompt and regenerate until the layout feels right.

Pro tip: keep your first app to ONE core feature. Simple ships; complex stalls.

Step 2: Turn the design into code for free

Have an AI coding agent build the app from your Stitch design. Recommended: Antigravity (Google's coding agent, best design quality). Alternatives: Claude Code or ChatGPT Codex (works on the free plan).

Paste into your AI coding agent
Build this as a responsive web app using the design I'm giving you. Make it work perfectly on mobile browsers. Keep the code simple and ready to deploy.

Output: a working app without touching a single line of code yourself.

Pro tip: build a WEB app, not a native one. It goes live instantly and you keep 100% of the profit (no App Store wait, no 30% Apple cut).

Step 3: Ship it and start charging

Deploy the web app (your coding agent will walk you through a free host), then put it behind a simple subscription.

  • Price it conservatively to start, e.g. $9/month
  • 10 users = $90/mo - 50 users = $450/mo - 100 users = $900/mo
  • Recurring revenue from something you no longer have to touch

Output: a live web app anyone can use from a browser, and income you keep 100% of.

//pro tipsKeep these in mind
  • Solve one annoying problem really well. Niche apps sell faster than do-everything apps.
  • Reuse the same Stitch + agent workflow to spin up a second and third app once the first one works.
  • Add a free tier to pull users in, then charge for the feature they actually want.
