Snapchat is a new app that aims to minimise the threat of sensitive pictures ending up in wide circulation. When users take and send a picture, they can control how long it is visible to the person who receives. After that, the picture disappears and can’t be seen again.

Amidst endless sexting scandals, Snapchat has created a photo-sharing app where each image expires after ten seconds of viewing, and in doing so, creates a safe space for friends to express themselves through images without fear of consequence.
