Little description is needed for this application, which has become the favorite social network for many people due to its powerful features when it comes to learning news in real time from around the world. However we do not want to highlight this part of the application, but we want to highlight its private messaging service. Perhaps it is not the most complete in the world and is more useful for sporadic messages or as a first contact before resorting to any other service. It is very simple and straightforward, allowing only the exchange of text, images and GIFs . The main advantage that can be highlighted is that the characters are not limited as if it occurs in tweets.

In the case of photos and videos, they can be sent in Instagram Stories format and cease to be visible to the interlocutor once they have seen it.
