In this study, the authors are concerned about influencing factors on mobile learning tools for the applicable and sustainable mobile learning environment. The authors proposed an impact model with five influencing factors namely usefulness, interactivity, motivation, facilitating conditions, and ease of use. The 60 students and 60 teachers in different learning and teaching disciplines in higher education institutions were involved in this study to evaluate the model. Initially, they were asked to fill the pre-usage questionnaire with their initial mobile learning experience. Then, they were allowed to use mobile learning tools in the Moodle mobile app and allowed to fill the post-usage questionnaire. The results reveal that the most significant influencing factor is the ease of use. Hence, the study concluded that ease of use would be the most significant factor to be considered when designing mobile learning tools in the mobile learning environment.
