I built Native App Builder OS for Codex, a complete Notion-based system for using Codex Desktop to build native iOS and Android apps from idea to launch.
Most people use AI coding tools with random prompts.
This template gives you a structured workflow instead.
It helps you use Codex Desktop as your main app-building workspace while keeping Xcode and Android Studio for builds, previews, simulators, emulators, logs, and release workflows.
Inside the guide, you’ll find:
App idea to product plan workflow
UX research and Mobbin design-memory process
SwiftUI and Jetpack Compose guidance
DESIGN.md rules for app themes, components, and UI consistency
iPad and Android tablet compatibility rules
GitHub, Xcode, Android Studio, Apple Developer, and Google Play setup
API, auth, database, security, privacy, and sync planning
Testing, performance, production readiness, and release safety workflows
App icon, store screenshot, landing page, and privacy policy guidance
Beginner-friendly Codex prompts for every major step
This is made for founders, indie hackers, designers, students, and beginner developers who want to build real native mobile apps with more structure, less guesswork, and better product thinking.
The goal is simple:
Turn Codex from “a coding chatbot” into a practical mobile app-building operator.
After weeks of 14–16 hour workdays, late nights and countless iterations, our new website is finally live! 🚀🌙
Built using Claude Code, Codex, Claude Design, Higgsfield and Figma.
AI is incredibly powerful when used correctly. With the right expertise, creativity and attention to detail, you can create something truly unique that doesn’t look or feel AI-generated.
Designed a trustworthy FinTech mobile app for global money transfers.
Process: Started with user flow & wireframes for 3-tap transfer, then built a scalable design system in Figma with 100+ components.
Outcome: Final UI focuses on clarity and trust — from onboarding to Home Dashboard ($12,450 balance), Send Money, and Money Sent success state. Built for conversion and speed.
