Introduction: Population aging is one of the most striking social transformations of the 21st century. Although it is not necessarily associated with illness, a significant increase in the prevalence of Systemic Arterial Hypertension (SAH) and Diabetes Mellitus (DM) among older adults has been observed—conditions that require the continuous, regular use of medication.Objective:To develop and validate a mobile application designed to expand/improve access to Primary Health Care (PHC) services for older adults with SAH and/or DM who use continuous-use medications. Method:This is a methodological development study with a quantitative, descriptive approach, carried out according to the steps established by Design Thinking methodology.Results: A total of 70 evaluators participated in the study, representing different profiles and objectives. The specialists (n=22) validated the developed application, assigning a final score of 83.75 using the System Usability Scale (SUS). Prescribing health professionals working in PHC (n=22) also evaluated the application, reaching a final score of 78.84 on the same scale. In addition, the target audience—older adults with SAH and/or DM (n=26)—evaluated the app through a structured questionnaire based on predefined themes. Conclusion:The “Digital Renova” application proved valid and reliable for practical use, offering an innovative alternative for expanding access to PHC services for older adults with SAH and/or DM.
