The app is only being distributed to subjects in a research study (N=275). We are not designing for consumer-level app review. We are calculating custom measures from raw accelerometer/gyroscope data. One of the measures is calculated every 30 sec on a sliding 6 min window, which we call P(E) the probability the subject is eating. This must run all day to monitor subject behavior. But we do not want to affect the activity rings measures.
