I’m developing a new mobile application and already have the user flows and wireframes in place; what I need now is a polished, visually engaging interface that feels native on both iOS and Android. Your task is to take the existing UX structure and translate it into a cohesive UI, complete with screens, components, and visual guidelines that my development team can implement without guesswork. You’ll start by exploring color, typography, and layout options that align with the app’s purpose, then expand that look into a full design system covering every screen and state. Editable source files (Figma, Sketch, or Adobe XD) with neatly organized layers are essential so assets export cleanly to Xcode and Android Studio. Key deliverables • Mood-board plus one signed-off sample screen • Full set of high-fidelity screens for both platforms, including normal, pressed, disabled, and error states • Asset hand-off package (icons, illustrations, color/typography styles, spacing tokens) Show me examples of recent mobile UI work—especially cross-platform projects—and outline your typical revision process in your proposal. If you need the wireframes in advance to scope accurately, just ask. I’m ready to move quickly and provide timely feedback throughout the project.
