Redux vs Context API in React

React Context and Redux solve different parts of the state problem. Context lets a parent make a value available deep in the component tree. Redux Toolkit gives you a predictable external store with reducers, actions, middleware, selectors, DevTools integration, and a mature ecosystem.
For React Native apps, the right answer is usually a mix: local component state for local UI, Context for low-frequency app-wide values, server-state tools or backend listeners for remote data, and Redux Toolkit only when global client state is complex enough to deserve a store.
