The primary and secondary outcomes will be determined in months 1 \& 2. Participants will continue for another 4 months and during that time data for exploratory measures will be collected.
During the first 2 months of the study, a micro-randomized trial (MRT) will be performed within the App+JITAI group (N=200). This MRT is designed to learn which push notification messages effectively prompt the user to interact with the appropriate content within the mobile application.
