Meta just released a brand-new Facebook Seller app for iPhone Meta has launched a new iPhone app called Seller, a Facebook app designed for managing listings on Facebook Marketplace. The app allows users to create listings with AI-generated details, manage inventory in bulk, track performance, and separate buyer messages from personal chats. Seller is available for free on the App Store, following Meta's release of an AI-powered children's story creation app called StoryKit earlier this week. Meta has launched a brand-new iPhone app officially called Seller, a Facebook app. The new Meta app is specifically for Facebook users managing listings on Marketplace, the social network’s virtual storefront for physical items. The new Seller app is only designed for iPhone, though it will run on iPad and Mac as well. Here’s the new app’s official description: Seller is a dedicated selling app for Facebook Marketplace. Manage your listings, message your buyers, and track your performance — all in one place. See what needs your attention. Your seller home dashboard surfaces what matters first — items to ship, buyers to respond to, listings to reprice — alongside a snapshot of how your sales are performing. Create listings fast. Upload photos and Meta AI fills in the details — title, description, price, category — so you can publish fast. Manage your inventory at scale. Reprice, relist, or delete in bulk. Create multiple listings at once. Your buyer messages, all in one place. Buyer conversations live here, separate from personal chats. See who’s serious, respond faster, and never miss a message. Track what’s working. See which listings are getting views, saves, and messages. Get pricing recommendations and relisting suggestions based on what’s actually selling. And here are screenshots from the new listing: Seller is the second new iPhone app introduced by Meta this week.
