PassingBy is an app for you to share messages or pictures with people passing by and interact with them. It sounds simple but can help you on various occasions; for instance, it can broadcast a  message for you to people in a library to ask them if anyone can help find a book.

Of course you can chat with people around you, comment on their broadcasts, or arrange meetups with some of them.

PassingBy designed a mechanism that you’d not find yourself interacting with people you don’t want to, for you should send connection requests anonymously before it connects the two sides who are both interested. To avoid engaging people you are not meant to, you can set a range limit for broadcasts. You also have an option to hide yourself from everyone.
