A tailored, culturally congruent, smartphone app co-developed with and for young Black and Latino women (18 to 25 years old) not yet publicly available offers a unique opportunity to conduct a feasibility, acceptability, and pilot RCT. Using this app, this pilot that will: a) assess feasibility of the sampling, consent, recruitment and retention techniques; b) collect acceptability and usability data and cultural congruence on the app; a and c) collect pilot data to test differences between intervention and control groups on the preliminary estimates of app effectiveness to inform a potential larger-scale study. The investigators propose YBLW between 18 and 25 years old in NYC will use a mobile-based health education app to access SRH education information. Additionally, those who use the tailored SRH app will have more self-reported connection to SRH services, better knowledge of SRH education domains, and how to link to clinical services (e.g., PREP, PEP, EC, birth control, HIV, STD, and pregnancy testing), compared to the control group. Analysis for the first aim will employ process measures and the second and third aims are mixed-methods aims.
