Define the contents of the mobile app
Every good app always starts with a concept, you don't need a very complete and fine concept to start your application development, but your idea is to be clear about the following issues.
What is the purpose of your application?
The first step is to clear the application. The purpose of the definition is to understand and motivate users to use your app.
What problems your app solves
A great application is to solve a single problem rather than solving multiple unrelated issues; For example, the system Settings app allows users to adjust all the settings on your device, providing users with a single interface to complete related tasks. If your app view solves multiple unrelated issues, consider writing multiple applications.
What your app contains
Consider what type of content your app contains, and how to interact with the user. Design the user interface and how the user interacts.
