This paper explores the factors affecting sustainable usage of digital services, such as mobile learning (m-learning) applications. We define a conceptual model of digital service sustainability and its measurement indicators and criteria. We assess the conceptual model by applying it to an adaptive m-learning application, which provides theory and assessment for driving school students based on their competence and learning progress. Additionally, the application provides mandatory self-evaluation reports to instructors after each practical driving session. The application assessment focused on how students’ performed the predefined tasks at a usability lab. The assessment was based on educational components in conjunction with user experience factors of delightfulness, adjustability, satisfaction, and reliability. The key qualitative performance aspects proved to be user-centered (e.g., individual differences in cognitive and learning capabilities), UI-focused (e.g., interaction and adaptability to screen resolution) and content-related (e.g., contextual delivery, emotional appeal, adaptability). These elements resulted in overall delightful and effortless experience. The evaluation results indicate that the user experience factors impact sustainable usage because students are emotionally attached to the application. Therefore, we suggest that emotional attachment assessment results may serve as an indicator for sustainability of m-learning applications. These results help mobile application designers to design sustainable applications.
