Abstract
BACKGROUND: After childbirth, women undergo substantial physical and emotional changes. Therefore, it is important to provide them with information that helps them identify what is expected during this stage, as well as signs and symptoms that indicate complications after they have been discharged from the hospital. OBJECTIVE: This study aimed to develop a health app-Towards Motherhood-that provides evidence-based information about the postpartum period and evaluate the usability of the app with the target population. METHODS: This was a validation study involving 80 participants, including 24 professionals from the obstetric health field, 15 professionals from the technology field, and 41 postpartum women. The app was developed using React Native technology. Health professionals evaluated the app's content using the Content Validity Index, technology professionals completed a validated evaluation to assess the appearance of the app, and postpartum women completed the System Usability Scale (SUS) to measure the usability of the app. RESULTS: The measurement of content validity using a Likert scale obtained an approval score of 99%. Regarding the app's appearance, 92% of responses were positive, reflecting favorable approval. The SUS usability score was 86.2, which represents excellent acceptance. CONCLUSIONS: The Towards Motherhood mobile app is a valid tool for promoting self-care during the postpartum period. The app's evidence-based information, user-friendly design, and high usability make it an essential resource for women during this critical stage of their live.
