Mobile App Development

We design and build mobile applications that users love and businesses depend on. Whether you need a cross-platform solution to reach both iOS and Android simultaneously, or a native application that pushes the boundaries of platform capabilities, EliteX delivers polished, performant apps from concept to App Store.

Cross-Platform Excellence

Cross-platform development has matured far beyond compromise. Modern frameworks like Flutter and React Native deliver native-quality experiences while sharing up to 95% of your codebase between iOS and Android. This means faster time-to-market, lower development costs, and consistent behavior across platforms — without sacrificing the performance or feel that users expect.

Flutter

Flutter is our primary choice for cross-platform projects requiring pixel-perfect custom UI and high-performance animations. Google's UI toolkit compiles directly to native ARM code, eliminating the JavaScript bridge performance bottleneck. We use Flutter for applications where brand-specific design, complex animations, and consistent rendering across platforms are priorities. Its widget-based architecture and Dart language enable rapid iteration with hot reload, while the compiled output delivers 60fps scrolling and transitions that users cannot distinguish from native apps.

React Native

For teams already invested in the JavaScript/TypeScript ecosystem, React Native offers a powerful path to mobile. We leverage React Native's bridge architecture with the new Fabric renderer and TurboModules for near-native performance. This approach is particularly effective when your web application is built with React — shared business logic, design systems, and developer expertise dramatically reduce development time. We use Expo for streamlined development workflows while maintaining the ability to eject to bare React Native when native module access requires it.

Consideration Flutter React Native
Best for Custom UI, animations, design-heavy apps Teams with React/JS expertise, web+mobile codesharing
Performance Compiled to native ARM — excellent Near-native with new architecture
Code sharing 90-95% between iOS/Android 85-95% between iOS/Android, plus web
Ecosystem Growing rapidly, strong Google backing Mature, massive npm ecosystem

Native Development

Some applications demand the absolute maximum from their target platform. When your app requires deep hardware integration, bleeding-edge platform features, or performance that cannot tolerate any abstraction overhead, native development is the right choice. We build native iOS and Android applications with the same engineering rigor we apply to all our work.

iOS with Swift

Our iOS development uses Swift and SwiftUI for modern, declarative user interfaces that take full advantage of Apple's design paradigms. We implement platform-specific features like WidgetKit home screen widgets, Live Activities, App Intents for Siri integration, ARKit for augmented reality, CoreML for on-device machine learning, and HealthKit for health and fitness data. Our apps follow Apple's Human Interface Guidelines meticulously, resulting in App Store review approvals on first submission and featured placements.

Android with Kotlin

On Android, we build with Kotlin and Jetpack Compose, Google's modern toolkit for native Android UI. Our implementations leverage the full Android platform: Material Design 3 theming, background work with WorkManager, Bluetooth and NFC integrations, camera and sensor access, Google Play Billing for in-app purchases, and Firebase services for analytics, crash reporting, and push notifications. We design for the Android ecosystem's device diversity, testing across screen sizes, OS versions, and manufacturer-specific behaviors.

We recommend native development when your app:

  • Requires advanced camera, AR, or sensor integration that cross-platform frameworks don't fully expose
  • Needs maximum GPU performance for gaming or real-time graphics
  • Must integrate deeply with platform-specific services like Apple Health, Google Fit, or CarPlay/Android Auto
  • Targets only one platform and wants the absolute best user experience on that platform

App Store Success

Building a great app is only half the challenge. Getting it approved, discovered, and adopted requires strategy and expertise that extends well beyond code. We manage the full app store lifecycle to ensure your application reaches its audience and grows.

Store Submission

We handle the complete submission process for both the Apple App Store and Google Play Store. This includes store listing optimization, screenshot creation, preview video production, privacy policy compliance, content rating questionnaires, and the nuanced review guidelines that differ between platforms. Our track record is first-submission approval on the vast majority of our launches.

App Store Optimization

ASO is the SEO of mobile. We research and optimize keywords in your app title and subtitle, craft compelling descriptions, design screenshots that convert browsers into downloaders, and implement A/B testing strategies using the built-in store experiments on both platforms. Proper ASO can increase organic installs by 30-50% without additional marketing spend.

Compliance & Privacy

Apple and Google enforce strict privacy requirements. We ensure your app meets App Tracking Transparency (ATT) requirements on iOS, properly declares data collection in Google Play's Data Safety section, implements GDPR-compliant consent flows for European users, and handles data deletion requests. Non-compliance can result in app rejection or removal — we prevent that.

Analytics & Growth

We integrate analytics from day one to measure what matters: retention rates, session duration, feature adoption, conversion funnels, and crash-free rates. Tools like Firebase Analytics, Mixpanel, or Amplitude provide the data foundation for iterative improvement, while crash reporting with Crashlytics or Sentry ensures stability issues are caught and resolved quickly.

Ongoing Support & Maintenance

Mobile apps live in a constantly evolving environment. New OS versions ship annually, device hardware changes, user expectations grow, and platform policies update. An app that isn't actively maintained degrades rapidly — within 12-18 months, an unmaintained app starts losing functionality, accumulating negative reviews, and facing potential store removal.

Our maintenance and support services ensure your app stays current, stable, and competitive:

  • OS Compatibility Updates — We test and update your app against iOS and Android beta releases months before they ship to users, ensuring zero downtime on launch day. This includes adapting to new APIs, deprecated features, and UI changes.
  • Performance Monitoring — Continuous monitoring of app performance metrics including startup time, memory usage, battery consumption, and network efficiency. We identify and resolve performance regressions before they impact user experience.
  • Security Patches — Regular dependency updates, vulnerability scanning, and security patches to protect user data and maintain compliance with evolving privacy regulations.
  • Feature Development — Ongoing feature additions based on user feedback, analytics insights, and business strategy. We run iterative development cycles to continuously improve your app's value proposition.
  • Store Listing Management — Keeping your store presence fresh with updated screenshots, descriptions, and keywords that reflect new features and capitalize on trending search terms.
