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.

A successful business shouldn't lose time to successful growth.
That's exactly what happened to Riley Taylor Tattoo Studio.
My lifelong friend Andrea and her partner Fernando have built an incredible reputation. More clients meant more inquiries, more consultations, more bookings—and more time spent answering the same questions, collecting reference images, coordinating appointments, and managing conversations across Instagram, Facebook, Messenger, email, and phone.
I built Riley Taylor Studio OS—a complete operating system for the studio.
Instead of scattered conversations, every client now follows one structured journey:
• Discover the studio through a modern, mobile-first website.
• Submit a detailed consultation instead of endless message threads.
• Receive confirmations, reminders, booking updates, and aftercare automatically.
• Track the entire process through a dedicated client portal.
• Get instant answers from an AI Studio Concierge before waiting for a human response.
On the studio side, the transformation is even bigger.
Instead of manually piecing together conversations from multiple platforms, every request arrives in one dashboard, already organized and ready for review. AI summarizes consultations, artists prepare quotes, manage bookings, update request status, and keep everything moving from a single Studio OS.
The result isn't just a better website.
It's fewer repetitive conversations.
Less administration.
Better communication.
A smoother client experience.
And, most importantly, more time for Andrea and Fernando to do what they love: create incredible tattoos.
This is exactly why I love building software—not because technology is exciting, but because the right system quietly gives people their time back.

This is premium at it's finest, love the mouse hover color saturation touch!
I'm incredibly humbled by what I was able to build using the Base44 mobile app alone.
This week, I am away from my workstation, but the theme and direction of the challenge inspired me to take on a project anyway.
I decided to redesign the website for my favorite local barbershop, KAYZPLACE, after noticing several usability gaps the last time I visited it.
I'll admit, I was skeptical about whether I could complete an entire website using only my phone. But Base44 completely changed my perspective. Having used several website-building platforms in the past, I can confidently say this is one of the most optimized experiences I've had for mobile-first development.
The seamless performance across mobile, tablet, and desktop without compromising functionality genuinely impressed me. Using only my phone, I built a completely redesigned version of the KAYZPLACE website featuring:
• Online service booking
• KAYGENT, a custom AI assistant that answers FAQs, helps customers choose the right barber and service, explains pricing, assists with reservations, and provides personalized aftercare recommendations between visits
• An admin dashboard for managing bookings, tracking customer data, and sending email notifications
These capabilities were either missing on the original website. The new experience makes booking appointments significantly easier while giving the business better tools to organize appointments and customer information.
The most exciting part is that every aspect of this project was created entirely within the Base44 mobile app, without ever opening my computer.
The final product is fully responsive and optimized for mobile devices, tablets, and desktop screens alike. I shared the finished website with the shop owner today, and his reaction made all the effort worthwhile. Seeing how excited he was about the transformation reminded me why I love building products that solve real problems.
A huge thank you to the Base44 team for creating such an incredible platform.
This challenge has been both inspiring and genuinely enjoyable, and it's amazing to see what's possible with the right tools even from the palm of your hand.

I genuinely think Base44 is the most impressive AI app builder I've used so far.
I challenged myself to build something beyond a simple website, so I created a complete AI-powered veterinary platform for a real local clinic, focused on solving real operational problems through automation.
What you'll find in the demo:
🤖 AI Veterinary Superagent for symptom triage (without diagnosing)
🐾 Pet Passport with complete medical records and a health timeline
👤 Passwordless Pet Owner Portal
📅 AI-assisted appointment booking
👨⚕️ Staff Dashboard for managing appointments, patients and AI conversations
🚨 Emergency case prioritization
💉 Vaccination reminders
📧 Automated confirmations and follow-ups
⭐ Review request automation
📱 Fully responsive experience across desktop and mobile
Demo: Experience the platform from both the pet owner and clinic staff perspectives, following the complete workflow from AI-assisted triage and booking to appointment management and Pet Passport updates.
