<![CDATA[This study aimed to design, develop, and determine the feasibility of the "PrimeMover" application as an Android-based digital library for physical exercise references. The application was developed using the no-code platform Kodular and was structured around four primary biomotor components (flexibility, SAQ, strength, and endurance) as the database categorization architecture to facilitate user navigation. This study employed a Research and Development (R&D) method adapted into six systematic stages: analysis, design, development, initial product, evaluation, and final product. The evaluation stage involved validation by two experts (a physical coaching expert and a sports technology expert), as well as field testing involving 40 students from the Physical Sports Coaching Study Program. Data were collected using a Likert-scale questionnaire that had demonstrated satisfactory validity and reliability (Cronbach’s Alpha = 0.918). The results of the descriptive percentage analysis indicated that the application achieved a feasibility score of 86.25% from the content expert and 100.00% from the sports technology expert, both of which were categorized as highly feasible. In the field testing phase, user responses yielded a feasibility percentage of 83.60%, which also fell within the highly feasible category. The findings of this study indicate that the PrimeMover application meets the requirements of academic validity and practical usability, making it highly suitable for implementation as a digital library platform for physical exercise references.
