SECTION 01

1. High-Performance Cross-Platform Apps Without Compromise

In the past, cross-platform apps earned a reputation for laggy WebViews and uninspired UI. Modern frameworks like React Native (with the new Fabric rendering architecture) and Flutter (powered by Apple Impeller and Skia graphics engines) have completely transformed the space. At MobileAppo, we engineer cross-platform apps that feel genuinely native. By structuring core state machine logic in clean TypeScript or Dart and bridging native platform components when needed, we give you the speed of one codebase with the visual fidelity of native platforms.

SECTION 02

2. React Native & Expo: Scalable Ecosystem & Fast Iteration

React Native allows teams to leverage the massive JavaScript and React ecosystem. With Expo's modern managed workflow, we implement Over-The-Air (OTA) JavaScript updates, allowing critical bug fixes to reach user devices instantly without waiting for App Store review cycles. For features requiring custom hardware access, our engineers write native Swift and Kotlin TurboModules that expose platform capabilities directly to your React components without performance bottlenecks.

SECTION 03

3. Flutter: Custom Pixel-Perfect UI Across Every Display Size

For consumer apps with bespoke brand UI, complex custom graphs, or canvas-based interactions, Flutter provides unmatched pixel-level control. Because Flutter controls every pixel rendered on screen via its Impeller engine, your app renders identically across iPhones, iPads, Android smartphones, and tablets.

SECTION 04

4. Automated Dual-Platform CI/CD with Expo EAS and Fastlane

Maintaining separate build pipelines for iOS and Android can drain engineering resources. We configure automated cloud build matrices using Expo Application Services (EAS Build) and Fastlane. Every merge into the main Git branch triggers parallel iOS TestFlight builds and Android Google Play Internal distribution packages, allowing your team to test new features on physical devices within minutes.

QUESTIONS & ANSWERS

SERVICE FAQS

What is the main advantage of React Native vs Flutter?

React Native uses native platform widgets underneath, making it ideal for apps that must blend seamlessly into the OS UI. Flutter renders its own pixels via Skia/Impeller, making it superior for apps requiring identical custom branding or complex vector graphics across both platforms.

Can we upgrade a cross-platform app to native code later if needed?

Yes. Our modular architecture isolates domain logic from UI presentation. If a specific screen requires native Swift or Kotlin execution, we can drop native views into your cross-platform hierarchy effortlessly.

How much cost do we save by choosing cross-platform?

Building a single cross-platform application typically saves 35% to 45% compared to building two separate native codebases, and reduces ongoing maintenance costs significantly.
