SNAPCHAT
Snapchat
Snapchat is a photo messaging application developed by Stanford University students. Using the app, users can take photos, record videos, add text and drawings, and send them to a controlled list of recipients. These sent photographs and videos are known as "Snaps". Users set a time limit for how long recipients can view their Snaps, after which they will be hidden from the recipient's device and deleted from Snapchat's servers.The above text is a snippet from Wikipedia: Snapchat
