The skyrocketing popularity of dating apps like Grindr, Tinder, and Jack’d has fueled recent increases in the transmission of HIV and other STDs. This has caused great concern among dating app users as well as heightened response by the public health community. While prevention efforts have been varied, recent strategies focus on dating app-facilitated dialogue about sexual health, widespread campaigning for HIV and STD testing, and targeted HIV pre-exposure prophylaxis (PrEP). Yet as each approach has its drawbacks, the worry and risk of HIV/STD infection continue to grow. Our innovation, Serify, aims to reverse these trends. Developed through a fall 2016 interprofessional entrepreneurship course at UCSF, Serify allows dating app users to conveniently verify and share their negative HIV/STD test results. In this way, users can boost their sexual desirability and minimize their worry and risk of HIV/STD infection.
