Insurance Payment App: UI Design

I designed a mobile app that processed insurance payments for patients. The start-up that developed the app wanted to simplify the payment process for paying health insurance in the United States.

Concept to Use
The client had several ideas on how to streamline the payment process for health insurance, but needed those ideas visualized into an app that could be used by millions of Americans
Visualization process
I took the concepts the client had in mind when it came to streamlining the payment process, and created a mock up for an app that would be easy to use for end users. The end users I had in mind were individuals most likely to utilize medical care; these users would vary in ailments and level of physical wellness. This app would have to adapt to these diverse users, and therefore I opted for a design using large fonts and buttons.
