Digitalization has changed the function of telephones not only to communicate but also to become smartphones. Various kinds of smartphones cause the confusion among the people in choosing while they have their own criterias of smartphones. This study makes a web-based application programs that implement Tahani fuzzy database into a decision support system of smartphones selection, then the software of this application is evaluated by testing the usefulness (usability testing) based on the five aspects of usability. In Tahani model, the standard relationship is still being used but to obtain information on its query, this model uses fuzzy set theory. The user inputs the criteria, the system searches the data, then delivers the output in the form of smart phones recommendations according to criteria required by the users (consumers) and are shown through the fire strength (membership value) which lies between 0 (zero) to 1 (one). The higher the fire strength (approaching 1), the closer the product from the search criteria or the greater the recommendation, on the other hand, the lower the fire strength (approaching 0) the further the product from the search criteria or the smaller the recommendation. The software evaluation result of this application indicates that the value of usability acceptance by the user is over the number of 3 (over the median) in the scale of 5 or has an average value of 4. In general, the web application software has a value of usability, i.e. learnability, efficiency, memorability, errors and satisfaction.
