About OpenApp

OpenApp is a desktop application that uses artificial intelligence to generate React Native mobile applications from natural language descriptions. Users describe the desired app features, and the tool creates a functional React Native project with screens, components, and project structure that can be previewed in real time. The generated code is stored locally on the user’s computer and can be opened in any code editor for further customization. The interface includes an AI assistant for iterative changes, a visual theme editor for styling, and a workspace for managing multiple projects. Projects are built with local storage and can be previewed on the device during development. The tool supports both Android builds today with iOS support planned for the future.
