Snapchat
Snapchat is a free app for mobile devices for sending picture and video messages. The corresponding recordings, whether photos or videos, can then be provided with effects, filters, emojis or texts.
A special feature of the app is that pictures and videos can only be played for a certain time, and the user can decide how long he or she gives the recipient the chance to view the "snap" (min. 1 second, max. 10 seconds). In the meantime, however, Snapchat also offers the option of viewing the sent pictures for an unlimited time. It is also possible to chat or make phone calls via the app.
