Chain LLC

Chain LLC is an uncommon social networking app developed specifically for group chat functionality. In simple words, It is a group chat app (but with a twist).

In Chain LLC, there is no option for one-to-one chatting - only group chat functionality. Although, Chain LLC does allow two groups to be merged into one with both group admin's permission.
And once the groups are being merged, the members of both groups can then discuss openly about any ideas.
