Although the use of technology in education can cover distance learning, it has not been specifically explained whether it is about mobile or immobile technology and whether it uses inside or outside of school hours. This study explores the adoption of mobile technology applications on students learning enrichment. This study data was collected from a junior high school in OKU Timur through observations and five student interviews. By applying qualitative research methods, the analysis is carried out by adapting structuration and technological experience theories. The results show that students in adopting English learning-based mobile applications are actively motivated to use them when completing self-initiated tasks in their non-instructional enrichment. In adopting the mobile apps, students are free to operate the application by their willingness and indefinitely space and time. Students were enthusiastic, motivated, and have a strong desire to deepen their knowledge and experience of English, especially in terms of acquiring new vocabulary. This research has provided output that teachers can use as a resource for developing old forms of learning. With this research, EFL teachers can apply more varied learning methods.
