This study will utilize a longitudinal cohort design. All Scanadu Scout investors (~5000 individuals) will be invited to participate in the study prior to receiving their Scanadu Scout™. Potential participants will receive a link to an online study platform. The platform will contain the Informed Consent form and all the study materials. After a participant reads and signs the Consent the participant will be enrolled in the study and a Scanadu Scout™ device will be sent. The participant will download the Scanadu Scout™ app from the App Stores (iOS/Android). The app will require a handshake with a Scanadu Scout™ device before it becomes fully functional to limit access to study participants.
