PurposeThe aim of this paper is to understand how the role of an mHealth artifact plays out in home care settings. An mHealth artifact, in terms of a mobile app, was tested to see how the quality of home care work practice was enhanced and changed. The research question is: In what ways does an mHealth artifact re-shape a home care practice and how does this affect the interaction between caregivers and the elderly and learning opportunities for the caregivers?Design/methodology/approachAn action research approach was taken and the study was conducted in a home care organization in a Swedish municipality. The data were collected through semi-structured interviews and observations that were conducted during home visits. Concepts of learning and boundary objects were used to analyze and distinguish interactions and conversations with the mHealth artifact.FindingsThe study shows how an mHealth artifact is re-shaping a home care practice and how this affects interactions and identifies learning opportunities. Views on the mHealth artifact as a designated boundary object as well as a boundary object-in-use must co-exist.Originality/valueThe study provides qualitative descriptions from using an mHealth artifact for home care, which is an emerging area of concern for both research and practice. It focuses on the interactional and organizational values generated from the actual use of the designed mobile application
