This study is designed to help us understand how the use of a mobile app (LetSync) developed for couples can improve HIV healthcare outcomes. We are asking BIPOC couples assigned male at birth and living with HIV to use the app over the 8 month study. During the study, participants will track appointments, medications, and goals. Our findings could lead to improved healthcare for people living with HIV.Over the 8-month study, you and your partner will both be asked to:• Complete 3 online surveys: each survey takes about 30 minutes. Online surveys will ask about mental and physical well-being, HIV care engagement, and communication/coordination within the couple.• Mail in 5 dried blood spot samples. We will provide free kits and step-by-step directions.• Do 5 take-home urine paper strip tests. We will provide free kits and step-by-step directions.• Take part in a private interview over Zoom or phone with the study team about your study experience.You and your partner will also be assigned at random to a study group.• Couples in group A will use the LetSync app for 8 months.• Couples in group B will not use the LetSync app, but they will do all other study tasks.You and your partner can each receive up to $430 for completing all parts of the study. Payment will be in the form of a debit card that can be reloaded with cash. We will mail you the debit card when the study begins.
