Mobile applications on the go have been adopted in many fields and areas. However, there has been little research regarding the development and use of a context‐aware application for users to improve their English listening comprehension through collaboration. This research aimed at helping users improve their listening comprehension with a combination of context‐aware tools and video‐based materials and attempted to investigate the learning strategies used in groups. Therefore, the researchers designed a Ubiquitous Fitness English Listening Comprehension System (UFELCS) incorporating collaborative listening activities into a fitness center. The researchers conducted mixed methods research using both qualitative and quantitative methods. The results indicate that the participants' learning performance was significantly improved. Moreover, the analysis of the interview data showed that the interviewees and their own groups held positive attitudes towards the creative ways of language learning, and their use of listening strategies was also revealed.
