React Native

What is React Native?

React Native is a framework for building mobile apps with React. You write components in JavaScript or TypeScript, and the framework renders them as real native UI elements on iOS and Android rather than as web views. One codebase, two platforms, genuinely native widgets on screen.

It splits from a regular web React app at the rendering layer. Instead of HTML and the DOM, your components map to platform views, and a bridge connects your JavaScript logic to the device's native APIs for the camera, GPS, notifications, and the rest. The newer architecture replaces that bridge with a faster, more direct interface. A retail brand that wants the same loyalty app on both app stores without staffing two separate native teams is the common case. Most code is shared, with small platform-specific branches where the experiences should differ.

React Native is not the same as Flutter, which uses Dart and paints its own UI, or fully native development in Swift and Kotlin, which gives the most control and the best performance ceiling. React Native sits in the middle. It trades a thin slice of native performance for a large gain in shared code and development speed, which is the right deal for a wide range of products.

React Native at Dallonses

React Native is how we handle a lot of our mobile app development. A client comes with a product that needs to live on iOS and Android, and one shared codebase means a single team can ship to both without doubling the budget or the timeline.

We are straight about the limits. Heavy graphics, deep platform integrations, or apps where every frame matters can push us toward native code, and sometimes we write that native code right alongside the React Native layer. For most app development, the shared approach wins on speed and on the cost of maintaining the thing for years. We bring the React experience our web work already runs on, point it at mobile, and ship an app that feels native because it is.

Need the same app on both stores without two teams? Let's build it.
