Codexium engineers designing mobile apps

Mobile App Development

Build high-performance mobile apps using React Native, Swift, Kotlin, secure APIs, telemetry, and modern release pipelines for iOS and Android.

Production-Ready Mobile Apps Engineered for Real Users

We build mobile apps that are fast, secure, and ready for scale. Whether it's cross-platform (React Native, Expo) or fully native (Swift, Kotlin), every build includes typed API layers, offline storage, push notifications, analytics, and a complete CI/CD pipeline for App Store and Play Store deployment.

Codexium integrates backend services, authentication, payments, billing, and cloud-connected features so your mobile experience feels seamless across devices and environments.

Cross-platform builds

React Native, Expo, and TypeScript-based builds for iOS & Android with shared component libraries.

Native performance

Swift and Kotlin for apps requiring advanced animations, offline features, or low-latency processing.

Secure API integrations

Typed API clients, OAuth flows, biometric login, payments, and event-driven cloud integration.

What we typically build in a mobile engagement

  • Reusable design system + component library
  • Offline-first architecture using SQLite, MMKV, or SecureStore
  • Push notifications using FCM, APNs & Expo Services
  • End-to-end API layer with validation & caching
  • Device telemetry, crash reporting, and monitoring
  • App Store & Google Play submission workflows

Why mobile-focused engineering accelerates product adoption

Users expect native-feeling animations, fast load times, and seamless syncing. Codexium engineers structure apps so that UI, state, network, and caching layers work harmoniously across devices.

With strong observability, error tracking, and real-time telemetry, your team sees how users interact and where optimizations matter.

When Codexium is a strong fit for mobile delivery

  • Your app needs offline mode, biometric login, or encrypted data.
  • You require cross-platform speed without losing native feel.
  • You want a scalable API layer and automated app releases.
  • You are preparing for a major launch and need senior oversight.

Monitoring & Crash Reporting

Integrations with Sentry, Firebase Crashlytics, or Datadog for user-impact insights.

Deploy automation

Automated signing, test builds, release channels, and staged rollouts.

Security & Compliance

Encrypted storage, secure tokens, PIN/biometric flows, and policy checks.

How Codexium collaborates during mobile engagements

We integrate directly with your frontend, backend, and product teams. All work is structured into milestones: design system, navigation, state architecture, API layer, offline mode, and deployment.

Knowledge transfer, documentation, and clean branch workflows ensure your team can continue evolving the app confidently post-engagement.
