DEFINITION
Apple's beta-testing platform for iOS. Up to 10k testers, 90-day build validity. Public test links give fast beta rollout to an external cohort.
- React Native→
Meta's framework for building native iOS + Android apps from React-like code, one codebase. Mature since 2020, though ~15–25% is still platform-specific code.
- Offline-first→
A design philosophy: the app's core functions work without a network and sync when online. Conflict resolution is mandatory, not optional.
- ASO (App Store Optimization)→
Optimising the app's store listing (title, keywords, screenshots, description, categories). As important as web SEO · just in the App Store / Play Store context.
- Expo→
Managed React Native platform · EAS Build, OTA updates, preconfigured modules. In 2026 the default for new mobile projects, except cases needing exotic native SDKs.
- EAS Build→
Expo's cloud build service for iOS and Android binaries. No local Xcode / Android Studio required · saves 2-3 hours a day on a typical new project.
- OTA update (Over-The-Air)→
Live JavaScript-bundle update without an App Store / Play Store review. Good for bug fixes, copy changes, feature flags · not for native changes.
