The app "Changer" was developed for community service for the better use of idle stuff from families. It helps local residents to exchange their second-hand articles and contributes connections between people. We are not intended to build up a second -hand marketing platform, instead, it aims to encourage people to exchange their unused things with other people regardless of money and value.

The project "Changer" was nominated as the best team of cooperation in 2015 INTERACTIVE BEIJING committee.
