<![CDATA[Introduction: Stunting remains a major nutritional problem in Indonesia that affects the quality of human resources in the future. Adolescent girls play an important role in preventing stunting, but their nutritional literacy levels are still low. This study aims to develop an Android-based mobile application and digital book as educational media for early detection and prevention of stunting in adolescent girls. Methods: The research was conducted in the city of Jambi in 2025 using the Research and Development (R&D) method through the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research subjects were 20 adolescent girls selected through purposive sampling. Data were collected through questionnaires, interviews, observations, and tests. Results: The needs analysis revealed substantial gaps in adolescents’ understanding of nutrition and hematologic health, particularly concerning the interrelationship between anemia, hemoglobin status, and stunting risk. These findings underscored the necessity for accessible, technology-based learning tools tailored to adolescent users. Consequently, a mobile application and companion digital book were developed to integrate early detection features such as hemoglobin and body mass index assessments with interactive nutrition education. Expert evaluations confirmed the high feasibility and content validity of these media, while preliminary trials demonstrated their user-friendliness, contextual relevance, and potential to enhance adolescents’ engagement and comprehension in stunting prevention. Conclusion:The mobile application and digital book developed are proven to be suitable for the needs, feasible to use, and have the potential to increase the knowledge and awareness of adolescent girls in preventing stunting. This technology-based intervention can be a strategic innovation in supporting the program to accelerate the reduction of stunting in Indonesia.]]>
