Check it out right now, download the app from the app store (https://itunes.apple.com/us/app/cheers!!!/id815565641). Make sure you have two or more devices ready to test it. Can you really party all alone?
Cheers is the party network that allows you to share with people who are with you right here and right now.
Most of the social networks take you away from where you are. Cheers brings you back to the moment and allows you to share with people sitting next to you instead of those who are miles away.
When you go to a gathering, just fire up Cheers and start sharing photos with people around you immediately. It requires no "friending" since it automatically finds out people around you.
