submit your proposal for a prototype of an App(application) that would be needed

submit your proposal for a prototype of an App(application) that would be needed in today’s society to improve a process, offer efficiency, or solve a problem. You may consider any industry (business, education, transportation, technology, science, arts, etc.) to determine the App of interest.
As you design your prototype consider the user interface components. Your App should be easy to operate, quick in response, effectively handle operational errors, and provide a simple user interface. The following list is some basic user interface requirements:
Content presentation
Easy Navigation
Simple interface
Responsive
Consistent UI elements
Feedback mechanism
Default settings
Purposeful layout
Strategical use of color and texture.
Provide help information
User centric approach
Group based view settings. (tutorialspoint, 2020)
Levels of Software Design
There are three levels of software design. First, the architectural design is the highest abstract version of the application. The high-level designs break up the architectural design into subsystems. Lastly, there is a detailed design that breaks the system and sub-system down to detailed modules. The technique of modularization divides a software system into multiple discrete and independent modules. Here are some benefits of modularization:
Smaller components are easier to maintain
Program can be divided based on functional aspects
Desired level of abstraction can be brought in the program
Components with high cohesion can be re-used again
Concurrent execution can be made possible
Desired from security aspect (tutorialspoint, 2020)
