is a new type of virus with hight infectious rate. The prevalence rate of this virus in international scale in 2020 for Indonesia reaches 34th in the world and case fatality rate (CFR) for Indonesia is 3.96. Malang City has been included in the red zone since the pandemic beginning, considering that Malang is a tourism city and also a city with lots of migrants. Currently, the most effective way to prevent COVID-19 is the application of hygienic sanitation. The application of sanitary hygiene is not well conveyed, especially to adolescents who have high mobility and unstable emotion. The delivery of information about this has not been supported by an optimal product, so it is necessary to have a product that is suitable to the needs and limitations of the target. Products that can be developed are Android-based applications. The purpose of this development is as an educational effort to prevent corona virus in Malang City adolescents. This research and development modified the model of Sugiyono, which consists of: (1) potential problems;(2) situation analysis; (3) product design; (4) product design validation; (5) product design revisions; (6) small group trials; (7) product revision I; (8) large group trials; (9) product revision II; (10) final production. Validation by media experts obtained results 72,7%, validation by material experts obtained results 76%. The results of the small group trying 96,7% and large group get results 96,6%, so it can be concluded that this product is suitable as a healthy support to prevent COVID-19. Further research is to find out the effect of giving interactive application to health behavior and knowladge about hygiene sanitation. It is also hoped that the application can be developed into another application like iOS.
