Diabetes is one of the diseases that requires treatment based on a health data diagnosis. Diabetes is caused by a disruption of the function of the hormone insulin so there is an increase in blood sugar levels in the body, which can increase the risk of premature death if there is no early detection. To make it easier for people to minimize the potential for diabetes, a comprehensive diabetes prevention application could be developed. One thing to consider in application development is interaction design analysis so that the designed application can be used well by the user. The approach used in this design is User Centered Design (UCD), which is based on the ISO 9241-210:2019 standard. UCD is a repetitive (iterative) process in which each phase focuses on the needs of the user. The planning phases are to understand and define the context of use, identify user requirements, design design solutions, and evaluate design solutions. The design and evaluation phases of design solutions are to be iterated twice. The design of interaction design solutions produces interactive design prototypes on mobile devices that meet usability and user experience (UX) goals. The interactive prototype is designed for Android operating systems using the Kotlin programming language, and part of the UI element is created using the Jetpack Compose toolkit using the Default Material Design 3 guide. The final stage of evaluation uses the usability testing method with 20 users. Usability and other UX goals such as effectiveness with a success rate of 84.57%, learnability achieved with a single Ease Question (SEQ) average of 6.125, utility achievement with a System Usability Scale (SUS) of 78.3, and helpful achievements with an Intrinsic Motivation Inventory (IMI) value on a value/usefulness subscale of 6.65. So, the designed solution has achieved the usability and UX goals.
