This paper investigates the impact of using mobile translation on the academic writing skill of EFL students. The purpose of this article is to be able to find out the pattern of using mobile translation in academic writing courses, and the effect of using mobile translation on students in the short and long term. This research uses a case study research design that occurs in EFL UIN Walisongo students in semester 6 in 2023. The data collection method uses direct interviews with students, and academic writing practice using mobile translation. The results show that the positive impact received by EFL students when using mobile translation is less than the negative impact they receive, the positive impact is only related to the process of churching writing assignments faster while the negative impact actually has a huge impact such as being lazy in learning and improving English skills, making students dependent on mobile translation. Researchers found a way to prevent EFL students from relying on mobile translation by 1. Practice reducing opening the application and switching to the traditional dictionary (dictionary) 2. Students must be diligent in opening dictionaries and using their vocab in everyday life, 3. Trying to translate scientific writing by manual means, 4. Improving language skills by reading English-language scientific journals and watching movies without subtitles, 5. Make a habit of constructing sentences using your own vocabulary guided by the grammar structure that has been learned without using the help of mobile translation
