24/7 personal health tracking will go mainstream.

In 2013, consumers will increasingly turn to digital tools to monitor and improve their health through exercise, sleep, and diet. Sales of wearable fitness-tracking devices like Fitbit are forecast to hit 90 million units in 2017, and the market for sports and fitness apps will exceed $400 million in 2016, according to ABI Research. And increasingly flexible and sophisticated sensors—embedded in clothing or shoes or attached to the skin like bandages—will help speed adoption and enable always-on monitoring. "This will explode in 2013," predicts Unity Stoakes, co-founder of StartUp Health.
