# Patina > Patina is an AI-powered iOS app that identifies almost any object from a single photo — maker, era, materials, and condition — then tells you what it's worth based on real sold prices, and where to sell it if you choose to. The expert eye, in your pocket. Point your camera at furniture, clothing, books, art, ceramics, jewelry, or collectibles. Patina identifies what it is in seconds, values it from actual sales data (not asking prices), and can generate a ready-to-post listing for the right marketplace. It's built for curious explorers, smart shoppers, estate managers, collectors, and anyone who would rather understand an object than guess at it. Core facts: - Platform: iOS (iPhone).
