Problem solving skills are one of 21st Century Skills. However, based on the results of studies and interviews students still lack in problem solving skill because most of them only study from textbooks at school. The purpose of this research is to produce science education media equipped with experimental manuals and context in the application that students can use anytime and anywhere either independently or by teacher guidance. This development research adopts the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The results of expert validation and legibility test show that the education KIT integrated mobile application is very suitable. Media expert validation obtained a score of 98% and material expert obtained a score of 99%. In addition to the validation results, a readability test was also carried out by the teacher and students with the respective scores of 96% and 91%. Based on the validation and readability test Edukit IPA is integrated with a mobile application as a practical, complete, and capable medium for practicing the results of student problem solving skill, because each stage of the experimental activity is based on indicators of problem solving skills.
