ABSTRACT The aim of design and building Fisikandroid application is presenting an education application based on mobile android that contains physics formulas with more attractive material so it will easy to be understood by students. Trial application respondent is students of SMA N 2 Sukoharjo. Methods of data collection are questionnaire and comparison of pretest result. The end result of this research is an educational application based on mobile android that contains the physics formulas of class X, which presented more attractive and easy to be understood by students. It is proved from the questionnaire that 86.67% of respondents agreed if this application has elements of education, 96% of respondents stated this is an attractive application, 82.67% respondents agreed the information in this application is easy to understand, and 86.67% of students experienced increases in value after using this application which means that this application can improve students understanding of the material presented.
