Learning the language is crucial to be included in a new society. For migrants, the smartphone is a commonly used device for staying connected, which could also be used for language learning purposes. This research concerns mobile literacy with newly arrived Arabic speaking migrants to Sweden and the use of mobile learning as a means for integration. The purpose is to investigate how mobile technology can be designed to support migrants' language learning process. The research concerns technology development where versions of a mobile application (app) are explored from a bottom-up perspective with Arabic speaking migrants. A qualitative method approach is applied, built on design principles focusing on the construction of situated artefacts and evaluation of performance. The results show that intuitive design and engaging content with connections to everyday social situations play important parts in sustaining motivation to engage with an app.
