What is an ISO post?
A short guide for neighbors new to demand-led listings.
ISO stands for “In Search Of.” Instead of scrolling endless supply listings, you state what you want: item, condition you’ll accept, budget, and optional hashtags (for example #bike, #kids). That clarity helps the right people notice your ask. If you’re hoping for a gift, trade, or Buy Nothing–style handoff, tags like #buynothing, #donation, or #gift sit in the same feed—neighbors who love to give can filter for them.
ISO App is built around that pattern: a reverse marketplace where your post is the starting point. Find what you're looking for. The reverse marketplace where your ISO comes to you.
When someone has a match, they can reach out in-app. You stay in control of status—active on the public feed, unlisted while you sort things out, pending when a deal is in progress, or found when you’re done.
