Cross-Platform Mobile App Development
iOS and Android Apps from a Single Codebase — Faster to Market, Lower Cost, Native-Quality Experience
We provide Cross-Platform Mobile App Development services that build iOS and Android applications simultaneously from a single shared codebase — dramatically reducing development time, cost, and ongoing maintenance effort compared to building and maintaining separate native apps for each platform. Our cross-platform development using Flutter and React Native delivers genuine native-quality experiences across both platforms.
Does your business need to reach users on both iOS and Android but cannot justify the cost of two separate native app development projects? Techmits IT Solutions builds cross-platform mobile apps that work beautifully on both platforms — with platform-adaptive UI components, smooth animations, and the native device integrations your app requires — at a significantly lower cost and faster timeline than separate native builds.
We deliver cross-platform mobile app development for businesses across India, the UK, Australia, the USA, Canada, UAE, and the Middle East — building business applications, consumer apps, e-commerce platforms, on-demand service apps, and enterprise mobile tools using Flutter and React Native for clients who need excellent iOS and Android coverage from a single investment.
Why Choose Techmits for Cross-Platform App Development?
Cross-platform development done well delivers apps that feel native, perform excellently, and are cost-effective to build and maintain. Done poorly, it delivers apps that feel generic, perform inconsistently, and are harder to maintain than separate native apps. At Techmits IT Solutions, we apply the expertise and care needed to deliver the former — cross-platform apps that genuinely compete with native quality.
Flutter Development
We develop Flutter applications using Dart — building high-performance, visually rich cross-platform apps with Flutter's expressive widget system that renders consistently and beautifully on iOS, Android, and web.
React Native Development
We develop React Native applications using JavaScript/TypeScript — leveraging the React ecosystem and a large library of native modules to build cross-platform apps with platform-native UI components.
Platform-Adaptive Design
We design apps that adapt to platform conventions — using iOS-appropriate navigation patterns on iPhone and Android-appropriate patterns on Android — so apps feel genuinely at home on each platform.
Native Module Integration
We integrate native device capabilities — camera, GPS, biometric authentication, push notifications, payments, and platform-specific APIs — using well-maintained native modules or custom native bridges.
Single Codebase, Two Platforms
We structure cross-platform codebases for maximum sharing while allowing platform-specific customisation — delivering consistent functionality with native-appropriate presentation on each platform.
Efficient Maintenance
A shared codebase means bug fixes, new features, and content updates apply to both platforms simultaneously — significantly reducing the ongoing maintenance cost compared to separate native apps.
How We Build Cross-Platform Apps
Our Cross-Platform Development Process
Platform Strategy
We assess your requirements and recommend Flutter or React Native based on performance needs, design requirements, existing web technology stack, and team considerations.
Cross-Platform UX Design
We design UI that respects both iOS and Android platform conventions — adaptive navigation, platform-appropriate controls, and visual design that feels native on each platform.
Core App Development
We build the shared application logic — screens, state management, navigation, data models, and business logic — that forms the foundation across both platforms.
Native Integration
We integrate platform-specific features — camera, biometrics, payments, notifications, device sensors — using native modules tested thoroughly on both iOS and Android.
API & Backend Integration
We connect the app to your backend APIs, authentication systems, cloud services, and third-party platforms with robust error handling and offline support.
Dual-Platform Testing
We test thoroughly on both iOS and Android — physical devices, emulators, and the App Store/Play Store TestFlight/internal test tracks — addressing platform-specific issues.
Dual Store Submission
We manage submission and review on both the App Store and Google Play simultaneously — handling review feedback and ensuring successful publication on both platforms.
Unified Maintenance
We maintain the shared codebase — releasing updates for both platforms simultaneously, monitoring crash reports on both, and evolving features efficiently.
Everything You Need to Know About Cross-Platform App Development
Get answers to questions about Flutter vs React Native, performance differences from native, design consistency, native module limitations, cost savings, and when cross-platform is the right choice.
What is the difference between Flutter and React Native?
Flutter uses Dart and renders UI using its own graphics engine (Skia/Impeller), providing consistent pixel-perfect rendering across platforms and excellent animation performance. React Native uses JavaScript/TypeScript and renders using platform-native UI components, giving a more platform-native look but with occasional inconsistencies between platforms. Flutter is generally preferred for visually rich, design-forward apps; React Native is preferred when sharing code with an existing React web codebase or leveraging JavaScript developer expertise.
How does cross-platform app performance compare to native?
Modern Flutter and React Native apps perform excellently for the vast majority of business and consumer application use cases. Flutter achieves 60fps animations consistently; React Native with the new architecture (Fabric/JSI) delivers significantly improved performance. The performance gap with native is most noticeable in graphics-intensive applications (games, complex 3D) and apps requiring deep platform integration. For business apps, dashboards, e-commerce, and most consumer apps, cross-platform performance is indistinguishable to users.
Will the app look and feel native on both iOS and Android?
With careful design and development, yes. We design apps with platform-adaptive UI — using appropriate navigation patterns, typography, and interaction conventions for each platform. Flutter achieves visual consistency through its own rendering; React Native uses native components for authentic platform feel. The result is apps that feel appropriate and familiar on each platform, not generic or foreign.
What are the cost savings compared to building two separate native apps?
Cross-platform development typically reduces development time and cost by 30–50% compared to building separate native iOS and Android apps, because the majority of application logic, UI, and business rules are shared. Ongoing maintenance savings are similar — updates and features are developed once and deployed to both platforms. The savings are largest for apps with straightforward device integration requirements and complex application logic.
Are there any capabilities that cross-platform apps cannot access?
Cross-platform frameworks can access almost all device and platform APIs through native modules and plugins. The main limitation is timing — very new or niche platform APIs may not have a cross-platform plugin yet and require custom native code bridge development. We assess your specific feature requirements against available cross-platform support and advise when custom native bridges are needed.
Can a cross-platform app be migrated to native later if needed?
Yes, though it requires substantial rework. If your cross-platform app grows to require native capabilities that are genuinely difficult to achieve cross-platform, a migration is feasible. In practice, very few apps reach this situation — the cross-platform frameworks are comprehensive enough for almost all business and consumer app requirements. We would advise you before starting the project if we anticipated future limitations for your specific use case.
Which is better for my specific app — Flutter or React Native?
The best choice depends on several factors: your design requirements (Flutter for maximum visual control), your existing developer team (React Native if you have JavaScript expertise), your web technology stack (React Native if you use React), your performance requirements, and the specific device APIs you need. We recommend the right framework after understanding your requirements in detail — we use both and choose based on project fit, not technology preference.
