This thesis examines the user experience (UX) and user interface (UI) of the onboarding process for VOS, a mobile application focused on mental health and well-being. The research aimed to identify strengths and weaknesses in the current onboarding flow and provide evidence-based recommendations for optimizing the process to improve user adoption and retention. Findings indicate that while VOS excels in aesthetic design, there are significant opportunities to enhance user guidance, reduce cognitive load, and better communicate the app's value proposition early in the user journey. Key issues identified include information overload, unclear personalization options, and premature presentation of subscription offers.
