Delivering high-quality design and development is important for any application, but it is especially critical when creating applications for specialized targets like medical devices. User experience should be a primary focus with the UI being easy to use and intuitive for the intended audience. As an engineer, you are already challenged with ensuring that the application is fast, secure, and able to communicate with a number of sensors and the underlying hardware. If you're lucky, you might be working with a talented UI designer who understands the sensitive nature of the design and is able to create a beautiful and user-friendly medical interface. In an ideal world, the designer could completely own the look and feel of the UI while you work your code magic in parallel. You could review and iterate the application, collaborating to deliver a solution that doesn't compromise on design, functionality, or performance. What a time to be alive!
