Webshark is a React Native app development company helping startups and enterprises launch iOS and Android apps from one JavaScript codebase. Our React Native developers work in TypeScript with the New Architecture, Expo where it fits, and native modules in Swift and Kotlin when an app needs device-level features. We build React Native MVPs, ecommerce and on-demand apps, fintech and healthcare apps and enterprise tools, connected to Node.js, Laravel, Python or Firebase backends. If you already run a React web app, React Native lets you share business logic, skills and even developers across web and mobile, which cuts time to market and long-term costs compared with two native apps. Every project follows ISO 27001 certified and CMMI Level 3 processes. Comparing approaches? See our cross-platform app development.

With React Native, your mobile apps share TypeScript business logic, API clients and team skills with your React web app. Features ship to iOS and Android together, bugs are fixed once, and one team maintains the product, lowering total cost of ownership.
A proven process takes you from idea to app store launch.
Work with our React Native app development company begins with a focused discovery phase. Over one to two weeks we define your users, business goals, must-have features and success metrics, and review any existing React web code or APIs that can be reused. We confirm React Native is the right fit for your product. You receive a prioritized MVP scope, user stories, a cost estimate and a phased release roadmap.
Our designers create platform-aware interfaces that respect iOS and Android conventions, such as navigation patterns, gestures and system fonts, while keeping your brand consistent. We map user journeys, design wireframes and high-fidelity screens, and test clickable prototypes with real users. Over two to four weeks you receive validated prototypes and a component-based design system that maps directly to reusable React Native components, saving development time later.
Before coding, our React Native architects plan the app structure with TypeScript, state management such as Redux Toolkit, Zustand or React Query, and navigation with React Navigation or Expo Router. We decide where native modules are needed for features like Bluetooth, payments or background tasks, and design the backend and APIs. You receive an architecture document and technical roadmap that keeps the app fast, testable and ready to scale.
Our React Native developers build in two-week sprints, delivering iOS and Android builds together from a single JavaScript or TypeScript codebase. You install each build on your phone through TestFlight or internal testing, join a sprint demo and adjust priorities. Every change goes through code review and automated tests. Where you already have a React web app, we share logic and components, which can reduce cost by 30 to 40 percent versus two native apps.
Testing runs throughout development, not just at the end. We write unit tests with Jest, component tests with React Native Testing Library and end-to-end tests with Detox or Maestro, then test manually on a wide range of real iOS and Android devices. We check performance, startup time, memory, accessibility and security. You receive test reports and a stable, release-ready React Native app that earns strong store ratings from day one.
We manage submission to the Apple App Store and Google Play, including store listings, screenshots, privacy labels, signing and compliance with each store's review rules. Builds are automated with EAS Build, Fastlane or GitHub Actions for reliable, repeatable releases. Crash reporting and analytics go live with the app. You receive a published app in both stores, typically within one to two weeks of the final build, with a phased rollout to limit risk.
After launch we keep your React Native app current and growing. We monitor crashes and performance, ship urgent fixes through over-the-air updates where store rules allow, and upgrade React Native, Expo and libraries to stay on the New Architecture. Using analytics and user feedback, we plan new features in regular releases. This steady care keeps your app secure, fast and compatible with every new iOS and Android version.

Answers to the questions teams ask before hiring a React Native app development company: cost, performance, timelines and support.
React Native app development is the process of building iOS and Android apps with Meta's open-source React Native framework, using JavaScript or TypeScript. A single codebase renders real native components, so apps look and feel native while sharing most of their code across platforms. Teams with React web experience can reuse skills, logic and sometimes components. A React Native app development company covers design, architecture, native module work, testing, app store launch and ongoing support, helping you reach both platforms faster and at lower cost than two native builds.
A React Native MVP usually costs $20,000 to $50,000, while full-featured React Native apps typically range from $50,000 to $150,000, often 30 to 40 percent less than building two separate native apps. The main cost drivers are the number of screens and user roles, custom native modules, backend complexity, integrations with payments, maps or devices, offline support and security requirements. Reusing logic from an existing React web app can lower costs further. A short discovery phase gives you a fixed estimate, and post-launch support is billed monthly.
Yes, React Native is well proven for large production apps. It powers apps at companies such as Meta, Microsoft and Shopify, used by millions of people every day. The New Architecture, with Fabric and TurboModules, improves rendering speed and native interoperability. With good engineering, TypeScript, careful state management, automated testing and performance profiling, React Native handles complex production apps well. As a React Native app development company, we plan for scale from the start, so your app stays fast as features and users grow.
Both React Native and Flutter are strong options for cross-platform apps. React Native suits teams with JavaScript or TypeScript skills or an existing React web app, because code, libraries and developers can be shared across web and mobile. Flutter offers highly consistent custom UI from its own rendering engine. Other factors include the native features you need, your hiring plans and long-term maintenance. Because we build with both frameworks, our recommendation is based on your product, team and roadmap rather than a preference for one tool.
A React Native MVP usually takes 8 to 12 weeks, while a full-featured React Native app takes 3 to 6 months. A typical schedule includes one to two weeks of discovery, two to four weeks of UX and UI design, development in two-week sprints with testing alongside, and one to two weeks for store submission. Custom native modules, complex backends, integrations and compliance reviews can add time. Building iOS and Android together from one codebase, and reusing existing React code, keeps React Native app development timelines shorter than native.
Webshark pairs React Native skills with mature delivery processes. We have delivered 580+ projects for clients in 18+ countries over 7+ years, under ISO 27001 and CMMI Level 3 certified processes. Our React Native developers have shipped production apps across ecommerce, fintech, healthcare, logistics, media and education, and our team also includes React web, backend, QA and DevOps engineers. As a React Native app development company, we focus on TypeScript code quality, transparent sprints and apps you fully own. Our team overlaps with US business hours.
Yes, we are also a Flutter development company. Our mobile teams build with both React Native and Flutter, so we can recommend the framework that best suits your product instead of forcing one approach. Flutter can be the better choice for highly custom, animation-rich interfaces or apps that will expand to desktop, while React Native often wins when you already have React web code or JavaScript developers. We explain the trade-offs clearly during discovery. To learn more about our Flutter work, see our Flutter app development page.
Yes, we can upgrade, fix and take over your existing React Native app. We start with a code audit covering architecture, dependencies, crash logs, performance and security, then share a prioritized plan. Common work includes upgrading to the latest React Native version and New Architecture, migrating to TypeScript or Expo, fixing crashes and slow screens, replacing outdated libraries and resolving store compliance issues. Once the app is stable, we can take over ongoing maintenance and new features, with clear documentation and handover from your previous team.
For React Native projects we use TypeScript, Expo or bare React Native, React Navigation, Redux Toolkit or Zustand, and React Query for data. Backends are built with Node.js, Python, Java Spring Boot or .NET, or Firebase, and connect through REST or GraphQL APIs on AWS, Azure or Google Cloud. Companion web apps use React or Next.js, sharing logic with mobile. We automate releases with EAS, Fastlane and GitHub Actions and monitor apps with Sentry or Crashlytics, choosing tools that fit your goals, budget and in-house skills.
You do. All React Native source code, native modules, designs, backend code, documentation and infrastructure scripts created for your app belong to you, and IP transfer is written into the contract. We sign NDAs before discovery starts so your ideas and business data remain confidential. Apps are published under your own Apple and Google developer accounts, and code lives in repositories you control. This lets you bring development in-house or change partners at any time without losing access to anything we built.
Yes, you can hire a dedicated team instead of a fixed-price project. A team can include React Native developers, React web and backend engineers, a UI designer, DevOps, QA and a project manager, all on monthly contracts. This model suits products with evolving roadmaps or companies that want mobile and web built by one coordinated team sharing a JavaScript stack. You set the priorities and the team works in your tools and sprint cadence, while we handle hiring and quality. For engagement options, see our hire full-stack developers page.
Yes, we provide support after your React Native app launches. Our plans cover crash and performance monitoring, bug fixes, over-the-air updates for urgent issues, security patches, React Native and library upgrades, compatibility with new iOS and Android releases, and new feature development. We agree response times by issue severity and share regular app health reports. Our team overlaps with US business hours, so problems your users or staff report during the working day are picked up quickly, and support can scale for major releases.
