Freight Driver Builds iOS App with Claude Code, Shares Practical Lessons

Practical Experience Building an App with Claude Code

A freight driver in Japan with only past dabbling in PHP and HTML used Claude Code to build an iOS app from scratch and successfully submit it to the App Store. The driver needed the app to comply with new recordkeeping regulations introduced in April 2025 that required filling out multiple paper forms daily.

Key Lessons from the Build Process

The developer shared several specific, practical takeaways from the six-month project:

• Prompt engineering matters: "One-line prompts don't work. You need a requirements document. Claude will build it with you."
• Expo build costs: "The Expo build limit is real. I ran 33 iOS builds in one month and got a $40 bill when I expected $19."
• Supabase pricing: "Supabase is NOT a flat $25/month. I upgraded 7 projects to Pro simultaneously and got a $66.93 bill instead."
• Interface advantage: "'Not being able to see what Claude Code is doing' is actually an advantage if you're not an engineer. Less noise."
• Burnout management: "Burnout is real. I went from obsessed to unable to open my laptop. 30 minutes a day beats weekend marathons."

Project Outcome

The app was downloaded by someone a month after launch without the developer's knowledge. The developer compiled all experiences—including failures, actual costs with receipts, burnout, and the App Store submission process—into a guide for non-engineers wanting to build real applications.
