Introduction: In Germany, informal caregivers receiving care allowances must undergo in-home care consultation visits, according to law. To support nurses during these visits an app was designed. Nurses were involved in all stages of the development to ensure that the user experience and usability of the finished product was satisfactory.

Objective: This study aimed to investigate the impact of user feedback on the usability and user experience of a mobile application designed to support in-home care consultation visits.

Methods: A mixed-methods approach was used. Nine nurses evaluated the initial app. Based on their feedback, significant adjustments regarding the design and content were made. In a second round the same participants and a focus group of six participants evaluated the modified version. Quantitative data was collected and analyzed using the System Usability Scale (SUS) and User Experience Questionnaire (UEQ) with SPSS. Qualitative data was analyzed through thematic analysis.

Results: Following the adjustments made to the app, all participants’ SUS scores were high (M=89.17, SD=7.4) and showed an improvement in usability compared to the first evaluation (M=83.33, SD=7.1). In terms of UEQ, scores were higher in all six dimensions compared to the initial evaluation. In the qualitative evaluation nurses mentioned only minor usability problems and expressed their satisfaction with the improvements made.

Conclusion: This study underscores the importance of conducting user-centered evaluations and implementing changes based on feedback. Adjustments made to the App have enhanced its usability and user experience, making it a useful application to support in-home care consultation visits.
