MVP (Minimum Viable Product) app development focuses on creating a basic version of the app with essential features to validate the idea and gather user feedback early. It prioritizes core functionalities that solve a specific problem or address a market need, ensuring rapid deployment and cost-effectiveness. By iterating based on user input and analytics, developers refine the app to meet evolving user expectations and market demands. This approach minimizes initial investment while maximizing the potential for future growth and scalability.
