<![CDATA[The development of the Staticfy application innovation was supported by Adobe Animate using coding programming. This study employed a Research and Development (R&D) method with the ADDIE model. The research was implemented in a public junior high school in West Java involving a total sample of 116 students. The study went through several stages, including validity testing, feasibility testing, limited trials, large-scale trials, and product testing. The feasibility of the Staticfy application media was determined through validation results from material experts and media experts. The results obtained from material experts reached 87.56%, while media experts achieved 94.38%, both categorized as highly feasible. The readability test result reached 95.83%, categorized as very good. The practicality test result was 95.75% with a very practical criterion. Furthermore, the product test showed a difference in the improvement of post-test scores between the experimental class and the control class. The results indicated a high criterion, demonstrating that the Staticfy learning media application is effective in improving junior high school students’ mathematical critical thinking skills.]]>
