First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a smartphone app called LetSync designed to help Black men who have sex with men and their partners stay engaged in HIV care and take their medications as prescribed. About 144 participants (80 couples) used the app for up to 14 months. The researchers measured medication levels in hair and blood samples, as well as how often participants stayed in care, to see if the app was easy to use and helpful.
