ABSTRACT: Learning Arabic has become a problem in this pandemic era, especially Arabic education students at IAIN Kudus have stated that complaints and the number of thesis targets on time researchers propose a new method solution, Arabic learning by implementing an Android-based lerning application, so that people can be taught easily where And anytime. The presentation in this article is part of a classroom learning review research report whose main focus is to see the effectiveness of online-based learning. This cannot be denied, because the presence of smartphone devices has made students not creative in learning. So the presence of Arabic learning application software based on Android is expected to make students more enthusiastic and independent in learning Arabic. This research is qualitative. Researchers evaluated the application using usability testing techniques. These findings indicate that the material for introducing Arabic vocabulary can be improved by applying second language acquisition theory. The researcher also found that the materials for introducing Arabic grammar with the behaviorist and innatist methods were not sufficient. In addition, user interface and user experience aspects should be considered to increase learner independence.
