Mobile Development

Overview

Mobile development at Stripe Systems is structured around a clear decision framework: we evaluate your performance requirements, platform-specific feature needs, time-to-market constraints, and long-term maintenance budget before recommending native or cross-platform.

For cross-platform projects, Flutter is our primary recommendation. Its Skia-based rendering engine delivers consistent 60fps UI across Android and iOS from a single Dart codebase. We structure Flutter projects using CLEAN Architecture with either BLoC or Riverpod for state management — BLoC for larger teams that benefit from its strict event-driven contract, Riverpod for smaller teams that prefer its declarative simplicity. React Native remains a strong option when your team has existing JavaScript expertise or when deep integration with web codebases is required.

Native development (Kotlin with Jetpack Compose for Android, Swift with SwiftUI for iOS) is recommended when your app requires heavy use of platform-specific APIs — ARKit/ARCore, background processing, Bluetooth LE, or hardware sensor integration where the abstraction overhead of cross-platform frameworks introduces measurable latency.

Regardless of platform, every mobile project follows TDD with structured test layers: unit tests for business logic, widget/component tests for UI behavior, integration tests for API communication, and end-to-end tests running on real devices via Firebase Test Lab or AWS Device Farm. We handle App Store and Play Store submission, review compliance, and ongoing release management through CI/CD pipelines using Fastlane and Codemagic.
