Build a real mobile app with Claude Code. From painful problem to store-ready product, one vertical slice at a time.
"A smaller app in users' hands beats a bigger app trapped in your prompts."
Find a painful, repeated problem with real evidence before you code.
Cut your app down to the smallest useful product, the 1-3-5 rule.
Use Claude Code and Expo as a disciplined engineering partner.
Test, secure, and de-risk the release before anyone else touches it.
Store assets, EAS builds, and a controlled three-ring rollout.
Price the outcome, not the stack, and find your first 100 users.
Score any app idea 0-10 across five factors before you decide to build. No more guessing if a problem is worth solving.
The exact vertical-slice method, PRODUCT.md and CLAUDE.md structure, and prompt patterns to keep the build inspectable.
Row-level security, secrets management, and the mobile test matrix used to make a release candidate actually trustworthy.
Private beta, warm community, then public. The exact rollout sequence and first-week dashboard to track.
Start with a system that ends in a store-ready product.
