Mobile language learning applications have changed how language is learned and have opened new windows for potential learners. At the convenience of our time, place, comfort and pace, we can learn or revise a language through our mobile gadgets. From the reviewed literature, it is evident that more data is needed to understand the users' views about mobile applications. Instead of focusing on a single mobile application, the researcher attempted to elicit the general perceptions of Turkish adult learners about mobile language learning apps. In line with this thought, a self-administered questionnaire was sent to potential mobile app users and 231 participants replied to the questionnaire. The aim of this study is to find out what perceptions adult learners in Turkey have and what their suggestions are to enhance future mobile language learning applications. For the close-ended questions, frequencies and percentages were taken, while for the open-ended question, content analysis was done. Easy access was considered as the greatest strength, while internet connection requirements and scarcity of interactivity were considered among the shortcomings. The participants offered some suggestions which can yield new paths for application developers, teachers and practitioners in the field of English language teaching and adult learning.
