Facebook Messenger is an application that allows you to message, audio, and video chat with people that you are connected through on Facebook. This social media platform has been popular in the world for about a decade or so. Messenger is the application developed by Facebook in California, united states, that gives you a way to communicate with your Facebook friends in a private manner. This app allows you to send messages to any of your friends without anyone else ever seeing them or knowing that you are even messaging. It is great to carry on private conversations, which may have started in a more public setting like a comment, picture, or blog post made by you or your friends. The application works best for windows, though there are versions that can run on other operating systems. It's important to note that this application allows you to do many other things, not just send messages. It allows you to chat with other people through video and audio as well, not just text. This is great because there are many applications out there that compete in this space. Still, none of them allow you to quickly find anyone in the world by their name (not some random username) and be able to be video chatting with them in a matter of seconds. This app is great for connectivity, networking, and just keeping in touch with the people you care about. You can even send money through the messenger app using the Facebook pay feature, which you can then link to a bank account and transfer money without any issues. Lastly, Facebook messenger for windows is completely free to download and use.
