Feasibility test results were obtained 95% for media experts, 90% for material experts, 80% for field practitioners, and 83% for target users. The subjects involved 21 students of class VIII as respondents. Development (media making), implementation (assessment by media experts, material experts, and field practitioners as well as conducting limited trials), and evaluations (evaluations of developed media, done during the previous four stages). Design (design of the items to be presented, preparation of material, preparation of material delivery flow in the form of flowcharts, making media storyboards, and the collection of materials needed in media development). The stages of the research that have been carried out are the analysis phase (goal analysis, curriculum and material analysis, analysis of the ability level and characteristics of the target users). The stages of the research carried out refer to the ADDIE development model covering Analysis, Design, Development, Implementation, and Evaluation. However, there are still few androids that are used by users, especially junior high school students for learning media. Android can be used for various functions, one of which is for learning media. This research aims to: (1) create a mathematics Encyclopedia product for junior high schools, and (2) Determine the feasibility of a mathematical encyclopedia.
