Before writing code or developing an application, there are several factors to consider, including the following:
What will be the main functions of the app?
Can you describe the problems your software solves?
Who are the likely users of the app?
What business goals will you be able to achieve?
Programming languages. Android apps are written in Java or Kotlin, while iOS apps are written in Swift.
Native device APIs. This will be determined by the functions of the device you want to use in your app.
Distribution method. This will significantly affect how you market your app and apply marketing tactics.
Free apps. You can download these apps for free, but some features remain blocked until you pay a certain fee.
Paid or premium apps. These apps must be purchased from the store. Because of the high cost of the model, a mobile marketing strategy is necessary to demonstrate the greater value of the app compared to free apps.
In-app purchases. The app can be free or paid, but the developer offers digital or physical products that users can buy in the app.
Subscriptions. These are similar to freemium apps, but have the added benefit of a constant source of income.
Describing the use cases for the application
Functionality mapping
Creating a minimum viable product (MVP)
Wireframing
Selecting a programming language and platform
Application design and coding
Analytics for mobile apps and testing
