The main purpose of this app is to allow peer to peer exchange of goods. A user signs in using Facebook or Google, and uploads a picture of something they would like to exchange, along with a small description. There should be a newsfeed filled with posts uploaded by users, a messaging system for users to contact each other, and a simple profile page for every user. The look and feel of the app should be very similar to the Mashable app for Android. The landing page (once signed in) should have 3 screens that the users can swipe among (The Feed, Messages, Profile).
Other necessary features include GPS and a Push messaging system.
