An app where you can share an item you no longer want, and get items you lack from other people in return.

The idea is to link people who no longer need an item with people who desperately need it. I'll demonstrate it in the following example. <br><br>Suppose that there is a person A, and a person B. The person A no longer needs an item 1, but needs an item 2. The person B has an item 2 and desperately needs the item 1. <br><br>They go on the app and create an account. <br><br>The person A goes on the app, and posts what he wants to give away and what he would like in return. The person B sees the ad, contacts the person A, they meet and exchange the items.<br><br>The person A has an item he needed, and the person B has the item he needed as well. <br><br>Both the item 1 and the item 2 are in a better hands, they both served their purpose, and everything is well. <br><br>The app would function as a link between people who want to give away something they don't need anymore, and the people who desperately need that item.
