Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people buying and selling used items locally. The main screen should show a clean grid of nearby items with photos, prices, titles, and neighborhood names. Add a search bar and category filters at the top. Tapping an item opens its photos, description, price, and general pickup area. Add a clear Sell button that opens a form for photos, title, price, category, description, and neighborhood. Save new listings on the device and show them in the browse screen. Use a friendly green and white style with large photos and easy-to-read text. Include realistic sample listings for furniture, bikes, electronics, and household items. Keep this first version local, without accounts, messaging, or payments.

Vibecode builds a first version from one prompt, and the checker would start with these parts: browse sample local listings with search and category filters; open an item page with photos, price, description, and general pickup area; create a listing and save it on your device. Plan on a weekend for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of OfferUp, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year).
OfferUp already has local buyers, items for sale, and user ratings from past transactions that a homemade marketplace would start without. A version you build yourself won't have these: OfferUp's local buyers and sellers; existing local item listings; accumulated buyer and seller ratings.
