Snapchat

Snapchat is an app that keeps you in touch with friends and family thanks to its interactive multimedia messaging system. Share your favorite events live or record them as video messages that automatically disappear without leaving a trace after a few seconds.

Just take a quick snapshot, add a message and choose how long you want your snap to be visible to your friends. That's it.

That said, for anyone to get your snaps, they'll need to have the app installed as well. As an added security measure, anytime you send a photo, and someone takes a screenshot, you'll get notified, so you're always in the know on who has pictures of what.

Once upon a time, Snapchat was simply a means to an end: basically, sending dirty pictures that could be easily erased. Thankfully, now this popular messaging platform has evolved to represent what looks like a major component for the future of social media: ephemeral video messaging.

All in all, Snapchat is a very useful application to keep in touch with friends in a fast, simple and visual way. After all, why send a lot of text when you can express it with a single photograph? A picture is worth a thousand words.
