A 2020 study found that 1 out of 7 man subscribes to one or more video streaming services, and there was a substantial increase in subscribers during the Covid-19 pandemic. Therefore, the subscription feature on a video streaming application needs to have good usability, so that users can easily subscribe. Vidio is a video streaming service provider based on Indonesia, which offers a subscription service called Vidio Premier. This study looks to find interaction design problems on Vidio’s subscription feature, and then develops a solution for those problems. Three methods are used to find problems: video streaming user survey, usability testing, and heuristic evaluation. Heuristic evaluation is used to find problems on Vidio’s subscription feature by comparing the design to 10 design heuristics. Meanwhile, usability testing is used to find problems that the users experienced. Those problems are then used as a base for the interaction design development in the form of a highfidelity prototype. The prototype is developed using the User-Centered Design approach, where all development are centered on the user. The finished prototype was tested by usability testing with Single Ease Question (SEQ) and System Usability Scale (SUS) metrics. Completion rate, time taken, and Customer Satisfaction Score (CSAT) is also used to measure the fulfillment of usability goals and user experience goals. The finished prototype increased the SEQ score from 5.925 to 6.927, and SUS score from 69.25 to 94.75. The prototype achieves 100% completion rate, therefore fulfills the effective usability, and reduced time taken by 46.81, therefore fulfills the efficient usability goal. The prototype also achieves the satisfying user experience goal by receiving a CSAT score of 96%.
