Introduction: The family has an extremely important role in identifying hearing disorders, especially in the first years of the child's life, and the use of technological resources such as Smartphone applications can favor this process. Objective: To analyze family adherence and the usability of an application as a technological solution for auditory and language follow-up in childhood. Methods: This is an observational, descriptive, and cross-sectional study. Families residing in three municipalities in the state of São Paulo and one in Rio Grande do Norte participated, between July and December 2022. Phase 1 consisted of applying a knowledge questionnaire on child hearing health, with 200 families, in order to analyze whether there is influence of prior knowledge on adherence to technology-mediated follow-up. In phase 2, using the System Usability Scale (SUS) and the Net Promoter Score (NPS), the usability and satisfaction of the application “Ei- Escuta Infantil” was analyzed by 10 judges and 18 users. Descriptive and inferential statistical analysis was performed using the Software Statistical Package for the Social Sciences (SPSS), with a significance of 5%. Results: The results were organized into two manuscripts. The level of prior knowledge of families about child hearing health was classified as “little knowledge” for 103 participants (51.5%) and attitudes towards child audiology services were predominantly positive (n= 193; 96.5%). There was no influence of the family income, education level and research participant (mother or father) variables on the level of knowledge in hearing health. Furthermore, 23.5% of the participants installed the app, and there was no association between adherence and the level of prior knowledge or with the mode of delivery of public/private or hospital/outpatient neonatal hearing screening. About usability, all judges evaluated the app with a score higher than the 50th percentile of the SUS, an average total score of 74 points, which demonstrates that the tool did not present major usability problems. In the family members' perception, the SUS median was equivalent to 92.5 points and, following the NPS criteria, 88.8% (n=16) of them would give positive publicity to the product. Conclusion: Families' knowledge about children's hearing health is predominantly restricted, but it does not interfere with adherence to the application. “Ei – Escuta Infantil” showed good usability and can be an auxiliary technological solution to improve parents' knowledge on the subject and maximize auditory and language monitoring in childhood.
