BeCare MS Link App

Now you can test your vision with your phone easily and effectively.

The BeCare MS Link app is an activity-based mobile app that collects quantitative and qualitative data to provide insight into Multiple Sclerosis and other neurodegenerative disease. The app guides the participant to perform a series of tests to assess their neurological and functional performance and track how it changes over time. I redesigned the UI/UX for the Contrast Sensitivity Test in this app, which is a test of the user’s vision whereby the user must decide whether a pair of rectangular patterns are a match or mismatch.
I especially focused on not using unnecessary color boxes and graphics which were main distractions of the test. I designed within the framework of operating system of iOS. I maintained all the same functionality and used same rectangular pattern images as they comply with certain standards of medical assessment. I also kept the original brand colors and icons.
