About

The PHASTT Study is focused on understanding of facilitators and barriers to mHealth use among young Black men who have sex with men (MSM), and testing a novel mobile app to increase HIV/STI testing and PrEP uptake.

Full description

The Sex Pro mobile application (app) being tested facilitates home HIV-testing, home sexually transmitted infection (STI) test self-collection, and pre-exposure prophylaxis (PrEP) uptake.
