Build Cross-Platform Mobile Apps

This bundle connects mobile app architecture, development, testing, and store optimization into a single workflow for iOS and Android. You choose a platform (Flutter, native Android, or React Native), design a clean architecture, build features with framework-specific patterns like MVVM and repository-based data access, write unit tests to lock in correctness, and optimize your App Store and Google Play listing before publishing - with crash and error monitoring and cross-session project memory built in throughout.

Use it when you're building a real mobile app from architecture through to store launch and want development, testing, and ASO handled as one workflow rather than switching tools at each stage. It suits teams building production Flutter or native Android apps that need clean, testable architecture. It is not the right fit for a quick prototype with no testing or store-launch needs, or for backend-only mobile features that don't touch app UI or store presence.

Choose your platform first, then design the architecture with the app-building agent. Develop functionality with the Flutter or Android-specific agents and skills, test with the unit-testing skill, and optimize your App Store/Google Play listing before publishing. An example starting prompt: "Create a Flutter widget for a profile screen: avatar with photo-change option, editable fields for name, email, phone, a save button with validation, and BLoC integration for state management."

Mobile developers building applications for iOS and Android who want architecture design, framework-specific development patterns, testing, and store optimization handled as one connected workflow.
