With the hmu app, you can find new friends who share the same interests as you do. You can search the people you like by setting up your profile, or browsing the profiles of other users with the hashtag or self-description.

You can also add friends by just clicking "Add Friends".

You can chat with new friends you add, and send them a message to get their attention. You can also message them to get more information about themselves.

And if you want to get to know the other user better, you can view their profile and send them a message.
