eBay UI design & app screens

eBay is a global marketplace for new and used goods sold through auctions and fixed-price listings. It serves a wide range of buyers and sellers, including collectors and small businesses.

The app is a reference for marketplace UX with auction mechanics: bidding flows, watchlists, seller listings, and dense search with detailed filters. Designers study its product detail pages, bid and buy-now patterns, condition and pricing displays, and the way it balances a vast, varied catalog within a familiar retail interface.
