Figure 1, the brainchild of a Canadian medical intern, is an instagram-style app that allows doctors to share pictures of patient ailments with a big social network of other doctors to trade advice and reach a diagnosis.
The insight was the constant, off-the-cuff consults happening in hospital hallways, where doctors would try and talk through the details of a case that was surprising or new to them.
Figure 1 has built a social network around that natural behaviour, and since its launch in 2013, the app has accrued 115,000 users. An estimated 20 percent of medical residents now have Figure 1 on their phones.
