React builds web interfaces that run in a browser. React Native uses the same component-based programming model to build genuinely native mobile apps — compiling to real native UI components, not a web view wrapped in a native shell.
Developers familiar with React can transfer much of their knowledge to React Native, though mobile-specific concerns — navigation, platform-specific APIs, app store deployment — require additional learning.
Cantonet Technologies builds both web and mobile applications, often sharing business logic and API layers between React web apps and React Native mobile apps for efficiency.
