This research used research and development (R&D) method with the 4D development paradigm. There are four steps to the process: define, design, develop, and disseminate. The information analysis approach utilized is a media achievability test conducted by media specialist and material specialists, and a media quality test was conducted by students as responders. The feasibility test results show that the android application of the probability theory of the same element permutation material based on RME is feasible with good criteria, based on an assessment of 87.50 percent by media specialist and an assessment of 84.93 percent by two material specialists. The results of media quality test of 60 students from partner schools showed good criteria, based on an assessment of 80.20 percent by students as responders. The data from the tests suggest that the android application of the probability theory of the same element permutation material based on RME is possible to use as a source of mathematics learning.
