The premise of this paper is to promote the results from a small study which sought to evaluate the effectiveness of three different prototype mobile applications, in promoting well being by the reminiscing of positive memories. Interviews were carried out with mental health professionals, including psychotherapists and psychiatric nurses, who were questioned on their opinions as to the effectiveness of the proposed app after using the prototype. The results indicate a significant interest in the proposed tool, with all professionals recognizing the effectiveness of positive reminiscing and indicating a willingness to take part in subsequent prototype evaluation developments.
