Launched to allow users around the world to celebrate Singapore's 50th year of independence, a messaging app with no words or keyboard is now available in the USA.

Singapore based startup Social Ink is behind the iOS and Android compatible Ink Messenger app, in which messages are drawn with a finger or stylus. Users can also curate their own stickers by drawing freestyle or cropping from existing images rather than taking them from existing templates. Apart from casual messaging, users can also send graphs, diagrams and charts.

Founder James Chen - who is also executive director of Singapore's Media Publishers Association - expects the unconventional mobile application to become a social noticeboard for millennials. "The app was inspired by the social noticeboard, whereby users can communicate individually, in a group or publicly in a freestyle, freeform manner, where possibilities for creative expression are limitless," he says.
