A single function display like a clock offers glancability and simultaneous access by multiple people that handheld screen interfaces do not. Digits is a general-purpose, wifi-connected numeric display that takes this simplicity and adds the versatility of the internet. Online data points are shown in real-time: stock prices, Facebook likes, temperature, time until the bus comes, etc.
For the 2014 World Cup I used Digits as a scoreboard for the games. I wrote a case study about the experience on Medium.
