Our group is finishing a new diet and nutrition-tracking app called Bitesome. Similar to the many diet-tracking apps that already exist for smartphones, the new app allows people to track the foods they each. But, somewhat differently, Bitesome tracks numerous factors that help public health and nutrition scientists better understand the context the underlies diet.
Bitesome utilizes sensors on the smartphones to better understand dietary context. This includes, GPS, motion, and camera data. Not only can researchers see when and where meals occur, but the nutritional content of each food item, query the neighborhood food environment, observe the physical activity that occurred before and after meals, etc.
Moreover, to better support science, researchers can access real-time Bitesome data from participants enrolled in research studies using a secure web portal. The website will support researchers by providing data reports for subjects in the study.
Bitesome is currently undergoing testing. The app will be available for iOS iPhones and Android smartphones in early 2018, starting with deployment in the ENACTS hypertension intervention study in Seattle — a new study funded by the National Institutes of Health, which is focused on minority health disparities.
The new Bitesome app builds upon previous smartphone app development in our research group, including past and ongoing studies that have used our CalFit smartphone app.
