Mobile App Development Company — React Native & Flutter Apps

For most business applications, we recommend React Native or Flutter. Both frameworks deliver near-native performance, share 85–95% of code across iOS and Android, and have mature ecosystems of third-party libraries. React Native is our default for projects that also have a web component — code sharing between your Next.js web app and React Native mobile app can reach 60–70% for business logic and data layers.

We recommend native development (Swift for iOS, Kotlin for Android) only when the app requires heavy use of platform-specific APIs — advanced camera processing, real-time audio/video, Bluetooth peripherals, or complex animations that cannot be achieved with the cross-platform abstraction layer. Even in these cases, we often use a hybrid approach: native modules for the performance-critical features wrapped in a React Native shell for the business logic UI.

Whichever framework we use, every mobile app we build includes offline-first data synchronisation, push notifications via Firebase Cloud Messaging, and biometric authentication. We use a backend-agnostic API layer that works with any REST or GraphQL backend. The CI/CD pipeline is configured from day one — automated builds, code signing, and deployment to TestFlight (iOS) and Internal Testing Track (Android) on every pull request merge.

We offer end-to-end mobile app development: product strategy, UI/UX design, development, QA, and App Store/Play Store submission. For startups, our MVP service delivers a working app with authentication, a core feature set, and a backend API in 10–14 weeks. We use Firebase for rapid prototyping and migrate to a custom backend (Node.js + PostgreSQL) once product-market fit is validated.

For enterprise clients, we build custom mobile applications that integrate with existing ERPs, CRMs, and legacy systems. Common use cases include field force automation apps with offline data collection, delivery partner apps with real-time tracking and proof-of-delivery capture, and customer-facing apps with loyalty programmes and in-app payments. Every enterprise app includes role-based access control, audit logging, and SOC 2 / GDPR-compliant data handling.

We also provide mobile app maintenance services — monthly updates, OS compatibility upgrades, performance monitoring via Sentry and Firebase Crashlytics, and feature additions based on user feedback. Our retainer model starts at 40 hours per month and scales based on your release cycle. We also handle App Store and Play Store compliance updates, including privacy label requirements and API deprecation migrations.

Our standard mobile stack is React Native with Expo for development and EAS Build for CI/CD. We use React Query for server state management, Zustand for client state, and React Navigation for routing. For Flutter projects, we use the Riverpod state management library and GoRouter for declarative routing. Both stacks are backed by a Node.js API layer with PostgreSQL, Redis caching, and file storage on AWS S3 or Cloudinary.

Quality assurance begins during development, not after. Every screen is tested on physical devices covering the top 20 Android devices in the Indian market and the latest 5 iPhone models. We run automated UI tests via Detox (React Native) or integration tests (Flutter) for critical user flows. Performance testing covers cold start time, scroll jank, and memory usage under load. We do not submit to app stores without passing all tests on both platforms.

Post-launch monitoring is built into every app. We configure Firebase Performance Monitoring to track screen load times in production, Sentry for crash reporting with source maps, and Mixpanel or PostHog for product analytics. We also set up dashboards for daily active users, crash-free session rate, and App Store ratings. Any regression triggers an automated alert to our team, and we triage critical issues within 4 hours.
