In this paper, the results of researcher' ongoing activities regarding the use of smartphones and a specific subject-app used at the Spanish National University of Distance Education (UNED) have been reported. The purpose of this trial is to assess the app's didactic use and potential to enhance student learning in university subjects in ubiquitous environments and developing generic competencies according to the European Higher Education Area (EHEA). To this end, a scale has been developed and validated to identify these factors based on the participation of 388 students from the class "Curriculum design and innovation" within the "University Degree in Pedagogy" program. This study has been developed through two perspectives; the first being through a descriptive methodology in which the current researcher has detailed the creation process of an app. The second perspective being through a quantitative methodology in which students' perceptions regarding the capabilities of smartphones and apps for improving learning processes in university subjects were assessed. The conclusions indicate that the use of apps developed specifically for following university subjects is highly valued by students as a new format which both supports and enhances learning practices while also providing not only further opportunities to establish connections and relations with their subjects, but also fostering collaborative work among students and professors. Therefore, it is recommended that universities continue developing new didactic strategies to connect both formal-informal and face-to-face ubiquitous learning settings.
