Integration

We build cross-platform apps using Flutter and React Native with shared logic, native UI, stable backend, and modular code. Faster updates, reduced dev time, and no need to build separately for iOS and Android—ideal for teams seeking efficient cross-platform app development.

Our design team builds interfaces in Figma and ProtoPie that adapt to screen sizes, OS behaviors, and usage patterns. As a reliable cross-platform mobile app development company, we focus on intuitive navigation and responsive layouts that feel native on any device.

We use Flutter’s rendering engine, custom widgets, and packages like Bloc and Riverpod to create fast, stable apps. UI updates happen in real time with hot reload, making Flutter a smart choice for startups and enterprises needing efficient cross-platform builds.

We develop cross-platform apps with React Native using JavaScript and TypeScript. React Navigation, Redux, and native bridges allow real-time UI updates and logic reuse—accelerating timelines without compromising quality or user experience across iOS and Android.

We migrate legacy apps to Flutter or React Native by refactoring UIs, aligning architecture, and integrating existing APIs. Our cross-platform app development services help modernize aging codebases without affecting core functionality or user data.

We connect apps to Firebase, Stripe, AWS, or custom systems using REST, GraphQL, and gRPC. Whether you're launching from scratch or scaling, these integrations support real-time sync and reliable performance across platforms for any cross-platform mobile app.

Frequently Asked Questions

Cross-platform app development allows businesses to build applications that run seamlessly on both Android and iOS using a single codebase. Developers use frameworks like Flutter and React Native to reduce development time, maintain consistency, and optimize performance across multiple platforms.

Cross-platform development offers faster deployment and cost efficiency by using shared code for Android and iOS. Native development provides platform-specific optimizations but requires separate codebases. Businesses looking for scalability and quicker launches often choose cross-platform solutions to maximize reach without doubling development efforts.

Our developers use industry-leading frameworks like Flutter and React Native. Flutter provides highly customizable UI components, while React Native allows integration with native modules. Both frameworks support rapid development, smooth performance, and easy maintenance, making them ideal choices for scalable applications.

Development costs typically range between $15,000 and $300,000, depending on project complexity, features, and integrations. Simple apps fall within $15,000–$60,000, mid-tier applications range from $60,000–$180,000, while high-end solutions with real-time capabilities or AI-driven features often exceed $180,000.

Timelines vary based on app complexity, features, and testing requirements. A basic app may take 3–4 months, while mid-tier applications require 5–8 months. Large-scale apps with advanced integrations, AI, or real-time processing can extend beyond 9 months, depending on development scope.

Cross-platform apps built with modern frameworks like Flutter and React Native achieve near-native performance. Optimized coding, native module integration, and efficient UI rendering techniques enable high-speed interactions, smooth animations, and seamless functionality across devices without compromising user experience.

Cross-platform development speeds up deployment, reduces costs, and simplifies maintenance by using a single codebase. Businesses benefit from faster market reach, consistent UI across platforms, and lower development overhead compared to managing separate Android and iOS applications.

Security is a priority, with measures including encrypted data storage, API security protocols, biometric authentication, and compliance with industry standards like GDPR and HIPAA. Regular security audits, vulnerability assessments, and secure authentication mechanisms help prevent breaches and unauthorized access.

Native applications can be migrated to a cross-platform framework, depending on code structure, dependencies, and platform requirements. The process involves evaluating existing functionality, rewriting components using Flutter or React Native, and optimizing performance to match the native experience across platforms.

Ongoing support includes bug fixes, feature enhancements, security updates, and performance monitoring. Compatibility updates for OS changes, third-party integrations, and backend improvements help maintain long-term stability and user satisfaction. Businesses receive continuous assistance to adapt and scale their applications efficiently.
