NearFi is a tool for real-time communication. It allows users to chat and interact with each other in their vicinity, within a 100-meter radius. This is done by creating a group and adding friends to that group. You can then send and receive messages to your friends and other people in your group. This is done by creating a public profile that has a location, a picture, and a description. You can then add people to your list of friends and send them messages.

Users can also create posts in their profile to get information or help in a particular location. These posts are visible to all users in that location. Users can also add tags to their posts to make them easier to find.
