Choose Unity for games with real-time graphics, Flutter for design-led apps with a custom interface, React Native when the team knows React and wants native components, and Swift for apps that target only Apple devices.
Start from the product, not the tool
The right technology depends on what the product does, not on which framework is popular. Ask whether it is a game or an app, which platforms it needs, and who will maintain it.
Unity
A game engine for 2D and 3D games with physics, animation and effects built in. Best when real-time gameplay is the product. See Unity development.
Flutter
A toolkit that draws its own interface from one codebase using Dart. Best when a consistent custom design matters. See Flutter development.
React Native
A framework that renders native interface components from JavaScript or TypeScript. Best for teams with React experience. See React Native development.
Swift
Apple's language for native apps. Best when you only need Apple devices or deep platform features. See Swift development.
