This is a really nice tool with an awesome UI and friendly environment. What this tool does, is it finds all the people near you (you can choose how near) and it allows you to message with them.

Mixer lets you make the most of the people around you.

Mixer key features:

• Browse profiles of people nearby

• Share conversations with the entire community

• Be a part of multiple communities by simply using the application in different areas.

• Use the neighborhood activity feature and Mixer will automatically notify you of new conversations in your area wherever you happen to be.
