Snapchat is an app that was created by three Stanford students. The app was meant to be a way for people to have temporary pictures or videos that would disappear after 10 seconds. The app was released in September 2011 and since then has been able to maintain its popularity with young people. Snapchat is a mobile app that allows users to send photo or video messages to friends or followers. It also allows the users to capture photos and videos. The app then deletes these messages and photos after 10 seconds or less, unless the sender chooses to save these pictures.
