Mobile language learning (MLL) has become an active area of research. This paper reports on the development of a MLL application to teach basic English language skills to pre-schoolers. The MLL application provides an opportunity for students to gain skills such as reading, writing, listening, and speaking. Designing science research was adopted to provide methodological support to structure our work. The MLL application was developed following the five activities (explicate problem, requirements definition, design and develop artifact, demonstrate artifact, and evaluate artifact) of the design science research methodology. The key findings of the study revealed that mobile phones are an effective tool in the language learning domain, and the proposed MLL application can be used to teach basic language skills to pre-school students with ease.
