Mobile Development Strategy

Mobile apps remain critical for businesses that need offline access, push notifications, device hardware integration, or a presence in app stores. At Nexis Limited, we help clients choose the right mobile development approach based on their specific requirements, budget, and timeline.

Cross-Platform vs. Native: The Nexis Perspective

Nexis recommends cross-platform development for 80% of mobile projects, and native development for the remaining 20% where platform-specific capabilities are essential.

When to Choose Cross-Platform

  • Business applications with standard UI patterns (forms, lists, dashboards)
  • Content-driven apps (news, blogs, e-commerce)
  • Projects with limited budget — one codebase serves both iOS and Android
  • Apps where time-to-market is critical
  • Teams that need to share code between mobile and web

When to Choose Native

  • Apps requiring intensive GPU usage (games, AR/VR, video processing)
  • Deep hardware integration (Bluetooth LE, NFC, specialized sensors)
  • Apps where the absolute best platform-native experience is required
  • Existing native development team and infrastructure

React Native at Nexis

React Native is our primary cross-platform framework because:

  • Shared knowledge — our web team already uses React and TypeScript
  • Code sharing — shared business logic between web (Next.js) and mobile (React Native)
  • Mature ecosystem — Expo, React Navigation, and extensive library support
  • Hot reloading — fast development iteration without full rebuilds

Our React Native Stack

  • Expo — managed workflow for faster development and easier deployment
  • React Navigation — declarative navigation with type-safe routes
  • TanStack Query — data fetching, caching, and synchronization
  • Zustand — lightweight global state management
  • React Native Paper / NativeWind — UI component libraries

Flutter at Nexis

For projects requiring pixel-perfect custom UI or targeting beyond mobile (desktop, web), Nexis uses Flutter:

  • Custom rendering — Flutter renders its own UI, enabling identical appearance across platforms
  • Dart language — AOT compilation for native performance
  • Widget-based architecture — composable, reusable UI components
  • Multi-platform — single codebase for iOS, Android, web, desktop

Mobile Architecture

Regardless of framework, Nexis mobile apps follow consistent architectural patterns:

Offline-First

Mobile apps must work without reliable internet. We implement local database caching (SQLite/Hive), optimistic UI updates, and queue-based synchronization for offline scenarios.

Push Notifications

Firebase Cloud Messaging (FCM) for Android and APNs for iOS, with a unified server-side notification service that handles both platforms.

Authentication

Secure token storage in platform keychains (iOS Keychain, Android Keystore), biometric authentication support, and automatic token refresh.

App Store Optimization (ASO)

Getting an app built is only half the challenge — users need to find it. Nexis handles ASO including:

  • Keyword-optimized app titles and descriptions
  • Screenshot and preview video preparation
  • Category and tag optimization
  • Review and rating management strategy
  • App Store Connect and Google Play Console setup

Testing Mobile Apps

  • Unit tests — Jest for React Native, Dart tests for Flutter
  • Component tests — React Native Testing Library
  • E2E tests — Detox for React Native, integration_test for Flutter
  • Device testing — real device testing across multiple screen sizes and OS versions
