This guide explains what a React Native migration technically involves and what it really costs in the Colombian market.","",{"cta":13,"intro":14,"sections":15,"conclusion":67},"Do you have your web platform ready and want to take it to mobile? Tell us how it's built and we'll give you a real estimate in under 48 hours.","You have a working React web platform. The backend is solid, the APIs respond well, users are already using it. Now the logical next step is taking it to mobile. The question almost every founder asks at that moment is: 'Isn't it just adapting what we already have?' The short answer is no. But the good news is that having the backend and APIs already built is an enormous advantage that significantly reduces the project's total cost. This guide explains exactly what needs to be done, how long it takes, and what it costs in the Colombian market.",[16,26,45,58],{"content":17,"heading":18,"subsections":19},"This is the starting point that generates the most confusion. Many people assume that because React and React Native share the same language (JavaScript\u002FTypeScript) and a similar component philosophy, the code simply 'ports over'. It doesn't. There's a clear line between what can be reused and what must be rewritten.","What Gets Reused and What Doesn't",[20,23],{"title":21,"description":22},"✅ What CAN Be Reused Directly","All business logic already in JavaScript: validations, data transformations, calculations, business rules. React hooks that have no DOM dependencies (useForm, useAuth, useFetch, state logic). API calls and the services layer (axios, fetch, React Query). Constants, utilities, helpers, and environment config. TypeScript types if the project uses TS. In well-structured projects, this can represent 40–55% of total code.",{"title":24,"description":25},"❌ What Must Be Rewritten from Scratch","All UI components: React web uses div, span, button, input. React Native uses View, Text, TouchableOpacity, TextInput. They're not interchangeable. Styling libraries: CSS and Tailwind classes don't exist in React Native. All styling is done with RN's StyleSheet or libraries like NativeWind. Navigation: React Router (web) is replaced by React Navigation. Third-party UI components: most web UI libraries (Shadcn, MUI, Ant Design) have no React Native version. Native behaviors: gestures, virtual keyboard, push notifications, camera permissions, device file access.",{"content":27,"heading":28,"timeline":29},"Once it's clear what gets reused, the project is structured into five major work blocks. The time and cost of each depends on the size and complexity of the original web platform.","The 5 Real Work Areas in a Migration",[30,33,36,39,42],{"step":31,"description":32},"1. Technical Audit and Mobile Project Architecture","Before writing a line, the web platform's code must be reviewed, portable logic identified, libraries with RN equivalents mapped, and what needs to be built from scratch defined. This takes 3–5 days and is critical for giving a reliable estimate.",{"step":34,"description":35},"2. Native UX\u002FUI Design in Figma","Even though the web exists, the mobile experience isn't a shrunken copy. Interaction patterns are different: tab navigation instead of sidebar, swipe gestures, virtual keyboard covering content, minimum 44x44px touch targets. Each main screen needs to be redesigned for the mobile context. This takes 1–3 weeks depending on the number of flows.",{"step":37,"description":38},"3. React Native Project Configuration","Project setup with Expo or React Native CLI, navigation system configuration (React Navigation), integration with existing APIs, mobile environment variable configuration, and build pipeline setup for iOS App Store \u002F Google Play. This foundation takes 3–5 days of a senior dev's work.",{"step":40,"description":41},"4. Native Screens and Components Development","The longest phase. Each web screen is rebuilt as a native screen, reusing existing business logic and hooks but with new UI components. A typical senior React Native developer builds 2–4 screens per week depending on complexity.",{"step":43,"description":44},"5. QA on Real Devices + Store Publishing","Tests must be run on physical iOS and Android devices, not just simulators. App Store review takes 1–3 business days; Google Play takes 1–2 days. Active developer accounts are required ($99\u002Fyear Apple, $25 one-time Google).",{"content":46,"heading":47,"subsections":48},"These ranges are based on Colombian market rates in 2025–2026 for professional development teams.

The entire visual layer must be rebuilt. Business logic and hooks are reusable.","In Colombia, a medium mobile app (10–20 screens) with an existing backend has a realistic cost of $18M–$40M COP in 2026.","Expo is the right choice for 80% of projects: it reduces setup time, simplifies builds, and covers most business use cases.","The App Store and Google Play publishing process has its own timelines — budget 1–3 business days for review.","Always budget 10–15% of development cost for annual maintenance: iOS and Android updates can break functionality if the project isn't actively maintained.","Taking your web platform to React Native isn't 'just adapting it'. It's building a new native presentation layer on top of a solid foundation you already have. The good news is that foundation — your backend, your APIs, your business logic — is already done and represents the most expensive work. What remains is building the mobile experience correctly: with design made for the phone context, with the native behaviors iOS and Android users expect, and with a well-managed publishing process.",[69,72,75,78],{"url":70,"name":71},"https:\u002F\u002Freactnative.dev\u002Fdocs\u002Fgetting-started","React Native Docs",{"url":73,"name":74},"https:\u002F\u002Fdocs.expo.dev","Expo Documentation",{"url":76,"name":77},"https:\u002F\u002Fdeveloper.apple.com\u002Fprograms\u002F","Apple Developer Program",{"url":79,"name":80},"https:\u002F\u002Fsupport.google.com\u002Fgoogleplay\u002Fandroid-developer","Google Play Console Help","development",11,false,"projectapp-team","How Much Does It Cost to Migrate a React Web App to React Native in Colombia?
