What is notes-app-ui?

notes-app-ui is a simple mobile notes application user interface built with React Native and Expo. React Native is a framework for building mobile apps using JavaScript, and Expo is a toolset that makes it easier to develop and run React Native apps without needing to configure native build tools from scratch. The app lets users create, edit, and delete notes through a clean, modern interface designed for mobile screen sizes. It also supports dark and light mode, including automatic switching based on the device's system theme preference, and adapts its layout for phones and larger screens. The codebase is organized with reusable components, custom hooks, and modular feature folders to keep things easy to maintain, following a component driven UI architecture. To try it locally, you clone the repository, run npm install to pull in dependencies, and then run npm start to launch the Expo development server. From there you can open the app on a simulator or a physical device using the Expo tooling. The README also includes a short demo video showing the interface in action. The project is written in TypeScript and was built as part of a mobile development learning cohort, specifically documented as an entry in the author's mobile development cohort archive, which tracks a series of projects built while learning mobile development. As a UI focused project, it does not include a backend or persistent storage beyond what is built into the interface layer itself, so it works best as a starting point or reference for someone learning how to structure a React Native and Expo app rather than as a finished notes service.
