AI can only be as good as the data it learns from, and a big challenge for AI in healthcare is that we don't have great data sets. The quantified-self movement seemed like it would change that, but once the hype cycle ended, people took their fitness trackers off, shoved them into a drawer, and deleted their apps.
The potential, however, is still there, and Relay started as a week-long challenge to create a new type of quantified-self app. Going in, I didn't know much about the quantified-self movement, so I started with some exploratory research—to understand the market, the users, their underlying needs, and desires. I looked into who these people are, what they track, and what tools are available to them. Then I talked to them about the QS apps that they use, used to use, and why they stopped using them.
