React Native App Development
React Native app development is building a mobile app in JavaScript or TypeScript using Meta's React Native framework, which shares its component model with React on the web and compiles to native views on both Android and iOS. At Beacon Coders that means one codebase for most of the app, with native Kotlin or Swift modules written only where performance or platform access genuinely demands them. Projects start at ₹3,20,000 / $3,850 and typically run 10 to 16 weeks.
When React Native is the right call — and when it isn't
Choose React Native when your team already works in React on the web and you want to share components, business logic, or at minimum a common language and mental model across your web and mobile products. It is also a strong fit when your app's UI relies on native platform components more than heavily custom rendering, since React Native bridges to real native UI elements rather than drawing its own, which tends to give a more immediately native feel out of the box than Flutter's rendered widgets.
React Native is the wrong call if your team has no React or JavaScript background — the framework's advantage largely disappears if you are starting from zero either way, and Flutter is often a more consistent single-codebase experience for a team with no strong existing preference. It is also a weaker fit for apps that need extremely custom, pixel-perfect animation-heavy interfaces, where the bridge between JavaScript and native rendering can introduce performance overhead that Flutter's compiled approach avoids more reliably. And if you only need one platform, a native build — Android or iOS — usually serves a single-platform product better than cross-platform overhead.

What's not included
React Native development does not include your web application build, even though logic may be shared — see web development for that scope separately. It does not include heavily custom native animation work better suited to platform-specific code, which we flag during discovery if your design calls for it. It does not cover marketing website builds or app store advertising (see digital marketing).
Frequently asked questions
React Native projects start at ₹3,20,000 / $3,850 and typically run 10 to 16 weeks. What moves the price: how much logic can genuinely be shared with an existing web codebase, how many native modules the feature list requires, and overall screen count. Full engagement models are on the pricing page.
Some of it, realistically. Business logic, data-fetching code, and state management can often be shared with the right architecture. UI components generally cannot be shared directly, since React Native uses native mobile components rather than HTML and CSS — a shared design system in principle, rebuilt components in practice. We assess your specific codebase during discovery rather than assuming a sharing percentage upfront.
Both ship one codebase to two platforms. React Native bridges to real native UI components, which tends to give a native feel with less design work; Flutter renders its own UI, giving more precise cross-platform visual consistency and generally smoother custom animation. If your team already knows React, that skill overlap often tips the decision — see Flutter development or cross-platform strategy if you are still comparing the two.
Not for most business applications. React Native's architecture has a bridge between JavaScript and native code, which can introduce overhead for very high-frequency updates like complex animations or gesture-heavy interfaces. For typical forms, lists, navigation and data display, the performance difference from fully native code is not noticeable to users. We flag it as a real consideration only when your feature list specifically calls for heavy animation.
Yes. Where a feature has no mature React Native library, or where performance requires it, we write a native module in Kotlin or Swift and bridge it into the JavaScript codebase. This is scoped explicitly during discovery once we know your full feature list, since native module development takes platform-specific expertise the same as a fully native build would.
Yes, under a single support agreement covering both Google Play and the App Store, since Flutter's shared codebase means most fixes and updates ship to both platforms from one change. Response times are named in the agreement, with an option for an ongoing sprint allocation as the app evolves.
How we build a React Native app
Discovery confirms whether your existing React codebase (if any) can genuinely share logic with the mobile app or whether that is a stretch worth avoiding — an honest assessment here saves rework later. This sits inside the same discovery stage behind every mobile app development project. Build runs in two-week sprints, testing against real Android and iOS devices throughout, with native modules scoped explicitly wherever a feature needs them rather than forcing a JavaScript-only solution that performs poorly.
