The Indonesian Central Securities Depository (KSEI) stated that the number of stock investors in Indonesia is increasing yearly. One of Indonesia's oldest and most widely used investment service applications is the POEMS application. Questionnaires were distributed to the POEMS application user with feedback on problems on the learnability aspect for novice investors. This study uses the User-Centered Design (UCD) method because the target user for improving the POEMS application is specific to novice investors who are different from professional investors. Initial testing tested nine essential tasks and resulted in 5 tasks that failed to be carried out by one or more respondents. Respondents' pain points and needs during interviews, observations, and initial testing simultaneously gave rise to an additional new essential task. Six essential tasks had to be tested in the second stage. After making a design solution by following each stage of UCD, all respondents managed to do 5 out of 6 tasks. In this way, the design solution has succeeded in improving the user experience for novice investors when they first use the POEMS application by referring to the interface guidelines and measuring specific metrics for the learnability aspect.
