I’m rebuilding the experience you see at https://seats.aero/ and need the complete design system for three fronts: a responsive website, a native iOS app, and a native Android app. Scope • Mirror the look-and-feel of the reference site—typography, colour palette, layout rhythm, iconography, micro-interactions, everything. • Core user journeys must cover flight search and an “aware travel” area that proactively surfaces routes, dates, or fares the user should know about. Deliverables 1. High-fidelity UI files for web, iOS, and Android (Sketch, Figma, or XD—whichever you prefer). 2. Clickable prototypes that let me trace each screen from search input to result details and the alert/aware section. 3. A design guideline document summarising colours, type scales, spacing, and component states so my dev team can implement pixel-perfectly. Acceptance criteria • Layouts match the reference within native platform conventions. • All states (loading, empty, error, success) are covered. • Assets are handed over in organised, export-ready layers. If you have questions about specific flows or want to suggest subtle UX improvements, let’s talk—it just has to stay visually consistent with seats.aero while feeling at home on both iOS and Android.
