BackgroundProvision of follow-up and care during treatment of people with suicidal intentions is a challenge for health professionals and experts in information and communications technology (ICT). Therefore, health professionals and ICT experts are making efforts to carry out these activities in collaboration by using mobile apps as a technological resource. ObjectiveThis study aimed to descriptively analyze mobile apps aimed at suicide prevention and to determine relevant factors in their design and development. In addition, it sought to analyze their impact on the support of treatment for patients at risk for suicide. MethodsWe considered 20 apps previously listed in the article “Mobile Apps for Suicide Prevention: Review of Virtual Stores and Literature” (de la Torre et al, JMIR mHealth uHealth 2017;5[10]:e130). To find the apps in this list, the most popular app stores (Android and iOS) were searched using the keyword “suicide prevention.” The research focused on publicly available app information: language, platform, and user ratings. The results obtained were statistically evaluated using 16 parameters that establish various factors that may affect the choice of the user, and the consequent support that the app can offer to a person at risk for suicide. ResultsOf the 20 mobile apps, 4 no longer appeared in the app stores and were therefore excluded. Analysis of the remaining 16 apps sampled showed the following: (1) a high percentage of the apps analyzed in the study (n=13, 82%) are provided in English language; (2) the sampled apps were last updated in 2017, when only 45% of them were updated, but the constant and progressive update of treatments should be reflected in the apps; and (3) the technical quality of these apps cannot be determined on the basis of the distribution of scores, because their popularity indices can be subjective (according to the users). User preference for a particular operating system would require further, more specific research, including study of the differences in the technical and usability aspects between both platforms and the design of medical apps. ConclusionsAlthough there are positive approaches to the use of apps for suicide prevention and follow-up, the technical and human aspects are yet to be explored and defined. For example, the design and development of apps that support suicide prevention should be strongly supported by health personnel to humanize these apps, so that the effectiveness of the treatments supported by them can be improved.

This paper proposes an interdisciplinary approach aimed to bring into practice some novel Software Engineering theoretical paradigms. The premise of these news paradigms is based on the idea of "ecologies" as realities that take place in the environment of a Software product. These "ecologies" are understood as tight but flexible interactions between the human, social, and technical components involved, where Software is just another component. However, the theoretical paradigms discussed do not offer a viable way to make sense of these ecologies into the practice of Software design and development. Thus, as a more operationalized approach, this paper proposes a framework based on Networks of Activities, a concept derived from Activity Theory, as a resource to help in the design, development, and evolution of these new emergent complex socio‐technical ecologies. This framework has been conceived as a tool for the design, capture, and, especially, to analyze the evolution of these ecologies. The concepts and notations used by the proposed approach are illustrated through a proof of concept that shows the essential ideas and their use in real scenarios. In this way, the concepts discussed contribute to the improvement of related fields like Requirements Engineering, Human‐Computer Interaction, or Software Architecture, among others.
