You are not the only one, I&#x27;m building mobile chat applications for a living (6 years now) and to this day I don&#x27;t &quot;get&quot; the Snapchat UI.<p>I believe the UI has been tweaked for users that are more impulsive. I know it sounds strange, but you open the app the first time and you are immediately asked to make a picture of something and then send it to someone. (even though you haven&#x27;t seen your available contacts yet)
