Preparing to develop mobile applications
At the preparation stage, you need to decide for whom, why and how the application will be made. All this information needs to be collected in one document, which will be the fulcrum for all participants in the process.
For whom. We determine the target audience - for whom we create the application.
For what. We describe what problem the target audience has and how the application will solve it. Hence the conclusion - what is the benefit for the company from the application. Understanding for whom and why you are making an application is a critical thing. Without understanding, there will be no real benefit, which means that the application will not be used.
What others have. Competitive analysis is a mandatory stage of preparation. Analyze what similar mobile apps are on the market. Try the most popular ones: note what is convenient and inconvenient, what is missing and what are the interesting features. It's also helpful to look at the reviews. They can be found directly on the application page in the market or google.
