Adoption and Performance Outcomes of a Mobile Health Education App Among Urban Ugandan Adolescents 12-18 Years Old: A Three-Week Post-Deployment Assessment

Mobile health education apps are increasingly used to promote health literacy among adolescents globally. However, little is known about their adoption and effectiveness in resource-limited settings such as urban Uganda. A mixed-methods approach was employed, including quantitative surveys to measure usage rates and qualitative interviews to explore user experiences. Usage rates varied significantly across different age groups (ranging from 35% among 12-year-olds to 60% among 18-year-olds). The mobile health education app showed promising initial performance, particularly in enhancing knowledge about adolescent-specific health topics. Future interventions should focus on targeted marketing strategies and continuous user feedback loops to optimise the app's effectiveness.
