Notes on shipping Expo & React Native apps — release engineering, CI, and the store-submission grind.

Boolean Build is where we write down the parts of shipping a mobile app that nobody documents: why a build gets rejected, how to get it through TestFlight locally, and the gates that keep a codebase from rotting between releases.

It’s run by Boolean Bros LLC, an independent studio that ships mobile apps. Most of what’s here comes from problems we hit for real — 16 KB page-size rejections, “misleading icon” flags, release-only crashes — and then had to solve.

Tools

Small, dependency-free CLIs that check a build before the store does:

• store-check — Android: the Google Play 16 KB page-size requirement.
• ipa-check — iOS: common App Store submission pitfalls in an .ipa.
