Since I stopped working there, Minus has rebranded as MeowChat. The following still deals with Minus:
Minus is a social network focused around sharing images with people around you. Whether you're at a baseball game or at a famous concert venue, you can use Minus to share images with those around you and chat about what's going on.
(I couldn't find the App Store description for Minus so here's the description for MeowChat. MeowChat is an app more designed for chatting.)
MeowChat is a fun place to chat and meet new friends. Chat instantly with new people nearby or around the world. If your friends aren’t on MeowChat, there are millions of people on MeowChat that want to chat with you.
Not comfortable chatting with new people? No problem! We have privacy settings that allows only your real life friends to be able to find and message you.
MeowChat is about making new friends, penpals and exploring the world. There are interesting people to chat with all over the world!
