STI is supporting the Smoke Sense Study, a crowd-sourced EPA study investigating the health and productivity impacts from wildfire smoke through citizen science, by designing and developing the Smoke Sense native mobile application (app) for Android and iOS platforms. The Smoke Sense app disseminates fire, smoke, and air quality data based on user location, and collects user observations on smoke, health symptoms, and changes in behavior. The app interacts with users through weekly notifications, quizzes, and a badge reward system. STI also developed and will be hosting the Smoke Sense Application Program Interface (API) and database to transmit and store the recorded data. The Smoke Sense Study will go live for the 2017 wildfire season.
