Your React Skills, Now on Mobile

Native Components, JavaScript Logic

Unlike Flutter, which draws every pixel with its own rendering engine, React Native's components map to the platform's actual native UI controls — a <Text> renders as a real UITextView on iOS or a real TextView on Android. That means your app inherits native look-and-feel details automatically, and it's also why React Native code isn't fully portable to the web without adjustment — the components are a mobile-specific layer, even though the JavaScript logic, state management, and API code around them usually is shareable with a React web app almost as-is. For a team that already has a React front end and a React-fluent engineering team, this is the real advantage: your developers aren't learning a new language, and validation logic, data-fetching hooks, and business rules can often move to mobile with only light adaptation.

The tradeoff shows up in performance-critical or gesture-heavy screens. Communication between the JavaScript layer and native code — historically a "bridge," now largely replaced by the more direct JSI in modern React Native — can still become a bottleneck in screens with complex animations or very high-frequency updates, like a real-time drawing canvas or an intensive map view. We handle that by writing custom native modules in Swift or Kotlin for the specific screen that needs it, rather than trying to force everything through JavaScript, which keeps the rest of the app simple while giving the few demanding screens native-level performance.

Compared with Flutter, we recommend React Native when your team already knows React and you want to reuse real logic from a web app, and we recommend Flutter when visual consistency across platforms and animation-heavy UI matter more than code sharing with an existing React codebase. Compared with fully native iOS or native Android builds, React Native trades a small amount of performance headroom on the most demanding screens for a single codebase and a much faster path to shipping on both platforms.
