I’m building an iOS/Android car-auction application that delivers the depth of information buyers expect from sites like mobile.de, yet packs it into a clean, intuitive mobile experience. The showpiece of the product is the vehicle-detail screen: specs, service history, image gallery, seller scores, and live bidding data must all surface without clutter or confusion. From the first search to the final bid, every step should feel effortless. You’ll take the lead from rough concept through polished prototype. That means mapping key user journeys, shaping low-fi wireframes, and converting them into high-fidelity, Apple HIG–compliant screens. I work in Figma and will need a clickable prototype plus a tidy design-system file (components, colours, typography, auto-layout). Deliverables • Full set of core screens: onboarding, search and filters, results list, vehicle detail, bid flow, watchlist, profile, notifications • Interactive Figma prototype that walks a buyer from opening the app to placing a bid • Scalable design system with reusable components and tokens Acceptance criteria 1. Vehicle-detail screen presents comprehensive car data clearly on iPhone 13–15 sizes and scales down gracefully. 2. Prototype demonstrates at least one complete buyer journey with smooth micro-interactions. 3. Assets are well-organised for developer hand-off. I’ll supply the brand palette and reference material once we start. Let’s craft a best-in-class auction experience for car enthusiasts. Basically, it should be copied and pasted from Mobile.de, but with fewer features and some extra features and easier to navigate with less background noise. Of course disain should be different but UX could remain the same.
