How to Ship Your First Mobile App with Claude Code.

This is the mobile version of my prompt library.

The web app playbook covered Next.js. This one covers Expo. Same approach, different output. A real app that runs on iOS and Android.

In case you missed the web app playbook:

Before you start: software you need

Create accounts and install these first. They’re all free to sign up.

• Node.js LTS. The engine that runs your app locally. Without it, nothing works. Download at nodejs.org (choose the Installer for your system, Mac or Windows).

• Expo Go. The app that shows your work on your actual phone while you build. Download it on your iPhone or Android from the App Store or Google Play. Free.

• Firebase. Your database and login system. Create a free account at firebase.google.com. No card required on the free plan.

• Claude. Paid subscription required for Claude Code. Make sure you’re on a paid plan at claude.ai before you start.

A note if you’re on a work laptop: you may need admin rights to install software.
