One of the challenges facing undergraduate science programs is keeping students interested in science and minimizing attrition from their discipline. Prior research shows that showcasing real-life applicability of science is one way to keep students interested. In this exploratory study using secondary data from two undergraduate science courses, we examined the impact of science mobile apps on students' interest and learning. The results show empirically that students think science mobile apps do help increase their interest in science. Furthermore, the ubiquitous mobile phone allows 24/7 access to these science apps, enabling enhanced learning and mastery of scientific concepts.
