Design a mortgage app.

Focus on the user experience and the key features that would make a mortgage app both functional and user-friendly. Consider the target audience, such as first-time homebuyers or seasoned investors, and tailor your design to their needs. Think about essential functionalities like mortgage calculators, application tracking, document uploads, and educational resources. Additionally, address how the app can simplify complex processes and enhance user engagement through intuitive navigation and visual design elements. Finally, consider any regulatory requirements or security measures that should be integrated into the app.
