Developing health-related smartphone applications for oral health education should consider the end-user's perspectives to ensure they will be usable. This study aimed to explore the opinions of secondary school students in Selangor, Malaysia regarding the use of a smartphone application for oral health education and to identify the features for an oral health education smartphone application from the perspectives of adolescents. Focus group discussions were conducted among Form Two (14-year-old) and Form Four (16-year-old) students from selected government secondary schools in Selangor utilising a semi-structured topic guide until data saturation was achieved. Data were analysed using framework analysis. Ten focus group discussions were conducted involving 77 participants. Mixed opinions were recorded on the use of health-related smartphone applications for oral health education. The preferred features in a health-related smartphone application are disease detection, have games and rewards, educational and fun, access to a dentist, reminders, and user-friendliness. Adolescents are aware of the positive aspect of using health-related smartphone applications for oral health education; however, they are wary of the need to install one. Nevertheless, identifying adolescents' preferred features of an oral health education app is the first step in developing an application tailored to their needs. Smartphone application could be a timely strategy to improve oral health education delivery and behaviour improvement for this age group.
