Wireframe-Skizze zu mobiler App-UI

Transform the rough wireframe sketch in the reference image into a high-fidelity mobile app UI mockup. - Design System: Modern, clean aesthetics inspired by [iOS 18 or Material Design 3], featuring smooth rounded corners, soft drop shadows, and a [vibrant blue] primary accent color. - Components: Convert rough sketch elements into polished UI components—scribbles into high-quality realistic placeholder photos, hand-drawn rectangles into styled buttons with subtle gradients, and sketched lines into readable, realistic text blocks. - Layout: Pixel-perfect alignment, balanced padding, and consistent spacing between sections. - Presentation: Display the screen mockup inside a realistic [iPhone 16] device frame mockup set against a minimalist clean background.
