EchoTrace is a behavior sensing tool developed by Vibrent Health for researchers, such as the ABCD (Adolescent Brain Cognitive Development) study. It is intended to be used by individuals who have already consented to participate in these ongoing research studies.

Full access to the app will only be provided to eligible participants who enroll in the voluntary research study.

EchoTrace integrates with the Apple Health app and can collect following contexts and sensor data, while the app is in the background:
- Movement Habits – by collecting Geolocation (GPS) and Device motion (Accelerometer derived data)
- Device Usage Habits – by collecting Charging state and Screen state behaviors
- Stress detection – by collecting Physiological data supported by HealthKit (from compatible Apple Health wearable devices related to heart, sleep, and activity)
- Environment and Mood Disrupters – by collecting Ambient Noise (Speaker Features) from the device’s audio; and Air Quality supported by HomeKit

** NOTE **
This application uses a location sensor in the background. Continued use of GPS running in the background can dramatically decrease battery life.
In addition, this app may use your location even when it isn’t open, which can decrease device battery life.
