This research is motivated because in the Department of PTIK IAIN Bukittinggi for the calculus course, the process of learning that developed so far only lecturers present the material and formulas in learning by being recorded and display in media such as infocus. In addition, students only use mobile devices as a means of communication, playing games and accessing social media. So researchers make a mobile-based application that can be used as an independent learning media for students in Calculus courses. The type of research that the author uses is Research and Development (R & D). The author uses an ADDIE (AnalysisDesign-Develop-Implement- Evaluate) R & D. And the system development model of SDLC (System Development Life Cycle) version of Waterfall. And test the product by using validity test, practicality and product effectiveness. Expert validity test results show that the designed application is declared valid with the value of 82.1%. While practicality test results show that the designed application is stated very practical with a value of 86.7%. The effectiveness test result also showed by the students that the designed application is declared very effective with 89.75% value. So the learning media in mobile-based calculus courses can be used and used by students of PTIK IAIN Bukittinggi.
