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 few stickers or a message and choose how long you want your snap to be visible to your friends. That's it.
That said, in order for anyone to get your snaps, they'll need to have the app installed as well.
