The Supporting Adolescents to be Resilient and Thrive (S-SMART) programme is a digitally enabled, peer-supported self-management intervention designed to enhance psychosocial and treatment engagement outcomes among AYLHIV. This pilot study evaluated the feasibility and acceptability of S-SMART among AYLHIV aged 15–21 years who received HIV treatment at two public primary care clinics in the Cape Town Metropole, South Africa. Thirteen AYLHIV received smartphones, mobile data, and access to the S-SMART app from September to December 2024. The pilot programme for S-SMART included activities, peer group sessions, and coaching by four peers living with HIV. Focus groups were conducted before (n = 17) and after (n = 12), to assess usability and their user experiences. Activity and programme completion was > 95%. Participants found the app user-friendly overall, though some faced issues with navigation, language and understanding certain content. Engagement was strengthened through peer support and facilitation. While the programme promoted psychosocial empowerment, HIV-related challenges such as stigma and disclosure fears need ongoing support.enAdolescents and youth living with HIVPilot testingSelf-managementSmartphoneSouth AfricaArticle
