The study has developed an android-based mobile application that can assist in the teaching-learning process of civic education in senior high schools. As a research-and-development activity, it employed the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Based on validation by material experts, the developed application was very feasible to use (89.04%), and the media experts concurred with this assessment (90.78%). During the large-group trials, the application scored between 3.96 and 4.68, meaning that it provides an excellent media or platform with high feasibility for the teaching-learning process of civic education in senior high schools.
