UI/UX Designer, Team of Two
I led the redesign of a remote patient monitoring app used by patients with complex needs as part of a partnership with CVS Health. A fellow designer and I would then use the research and lessons from this project to design a brand new web app, the Mozzaz Care App.
01
CVS Lessons & Problems
The redesign experience went beyond updating an app for CVS, it laid the foundation for a new remote patient monitoring application.
We learned new accessibility best practices, like icon labelling and visual disability customization. We also learned more about clinician touchpoints and how users navigate the app with CVS's research insights. I personally learned a lot about UX and UI design from CVS's own team.
/ CVS App Problems
Users had difficulty navigating the app because there were many subpages and poor navigation instructions.
CVS's colour palette made UI design too homogeneous and users complained about elements being hard to find.
Limited customization options.
The image above demonstrates the complicated subpage navigation.

Adapting & Improving
When redesigning the experience into the Mozzaz Care App, we addressed those navigation and usability issues head-on. Instead of spreading tasks across multiple subpages, we consolidated core functions, like logging data, submitting forms, checking reminders, and messaging care teams, into a simplified structure that surfaced the most frequent actions on the home screen.
We conducted surveys and testing to identify which actions were most important to users and which actions could be consolidated. We settled on a breadcrumb-style header for better navigation communication and limited the number of subpages to three.
Early versions of the home screen had smaller content crammed together for faster navigation, but users with visual and mobility impairments struggled to navigate the small UI, so the home screen was redesigned with large image-heavy cards. The new card UI tested very well with users and reduced errors by 50%.
The new Mozzaz Care App also uses a colour palette with more visual distinction. It also prioritized icons and images where possible for faster recognition.
/ Research in Healthcare
User research required balancing useful insights with the sensitivities of working in healthcare. I used user and clinician data to understand daily routines, pain points, and communication gaps, while ensuring privacy through de-identified notes and secure data handling. One of the biggest challenges was building trust with stakeholders and users. Users required respect and might be hesitant to provide feedback, and clinicians had limited time to participate. By focusing on empathy, clear consent, and flexible research methods, like unmoderated interviews and anonymized surveys, I was able to gather meaningful feedback without compromising confidentiality.

Wishlist
Although the Mozzaz Care App was a significant improvement and addressed many user issues with the original CVS Health App, there are designs I wish I could have done differently.
Below you can see a recent mockup I made of the "My Schedule" screen. I was thinking about how I would apply colour, hierarchy, and whitespace to direct attention now that I am a more experienced designer. I believe my newest design is a better reflection of user needs based on the feedback they provided.
I hope to be able to work in the healthcare space again one day. I always appreciated the importance of empathetic design in healthcare.
