Vast amounts of mobile services and applications are being offered to end users via app stores and service providers’ web sites. In addition, users take part in the distribution of services by recommending services to each other, i.e. through various word-of-mouth practices. To understand the current patterns of user-initiated service distribution, we conducted an exploratory survey study (N=203) to investigate the recommendation practices and motivations of mobile service users in situations where they recommend to other(s) and other(s) recommend to them. We found that the dominating way to recommend mobile services to others is to tell about the service in face-to-face situations, despite available support for electronic sharing in mobile situations. Social media was also used, but clearly less frequently. Based on the findings of this study, we present design ideas for supporting users in their recommendation practices.
