One-stop mobile applications are trending in recent years. Several years ago, we used one mobile application for one function only. Now one mobile application has turned into a one-stop mobile application that has many functions. This article discusses a review of articles that discuss technology adoption in increasingly multi-functional mobile applications. The method was used by searching on five selected journal sources: Elsevier, Emerald Insight, Springer, IEEE Xplore, and Google Scholar. Search articles on the five journal sources using the keywords "mobile application,""technology adoption,"and "UTAUT."From the search found 1905 selected articles. Selected 1905 articles by reading the title and some abstracts to become 164 articles. Furthermore, 164 articles were read carefully and selected more strictly according to the topic, so that there were 31 selected articles. Continued the stage by mapping the 31 selected articles. This literature review concludes what constructs are most widely used in the UTAUT technology adoption model. In this review, additional constructs are also generated, which are the most used to complement the constructs of the UTAUT model. With the discovery of these important constructs, it is hoped that they can become a reference for conceptual models and research gaps in further studies.
