In the mobile app design process, I conduct thorough user research to understand the target audience and their needs. This informs the creation of detailed wireframes outlining the app's structural layout and functionality. Interactive prototypes are then developed to validate the user flow and gather feedback for iterative improvements. High-fidelity mockups are crafted to provide a visually polished representation of the app, including design elements, color schemes, and typography. Finally, a comprehensive design specification document and style guide are delivered to guide developers in implementing the design with precision and consistency.
