The development of Android-based mathematics learning media aligns with the advancements of Industrial Era 5.0. This study aims to develop an Android-based mathematics learning media on geometry that is contextually relevant to tourist destinations. The methodology employed was the ADDIE approach, comprising five phases: analysis, design, development, implementation, and evaluation. The total sample is thirty-five students, and it consists of three stages. The initial phase involved one-to-one interactions with three students, while the subsequent small group phase engaged six students. Last, a field test was conducted with sixteen students in fourth grade. Document analysis, interviews, questionnaires, and tests were conducted in the data collection for this study. Questionnaires and tests then analyzed the data. The data were then analyzed using. An Android-based mathematics learning media utilizing the context of tourist destinations was developed using MIT App Inventor. The media was highly valid, with an average score of 93.86%. It was also highly practical, with an average score of 93.51%. Additionally, it was determined to be effective, with an average score of 91.21%. Research implies that the Android-based mathematics learning media in the context of tourist destinations can be used to teach and learn geometry using technology and contribute to the preservation of Indonesia's cultural heritage.
