A Business Guide to Understanding the App Development Process

Would you like to develop an app but don’t know where to start? The app development process can be overwhelming for a business: there’re many things to consider, making it easy to lose track of critical details.

In our previous article, we’ve highlighted how an app is created, focusing on how your idea can come into reality. This article focuses on the technical process of developing an app, highlighting the steps needed to have your project ready for app stores.

📌 Mobile app development steps

Product roadmap

The first step for the app design and development is the product roadmap. A product roadmap outlines the vision, goals, and objectives of the project and it should consider the following aspects:

  • The target audience: Who is the app for? What are their needs and pain points? How can the app address those needs?
  • Market trends: What are the latest trends in the market? How can the app differentiate itself from competitors?
  • Resources: What resources are available to develop the app? What is the timeline and budget for the project?
  • Goals and objectives: What are the goals and objectives of the app? What features and functionalities should be included to achieve those goals?

Technology stack

A technology stack is the set of technologies used to develop an application, including programming languages, frameworks, databases, front-end and back-end tools, and APIs. You can think of it as the material needed to build a house: you need to put it together before you start the actual building. This is critical to the app development process.

When choosing the tech stack for your app you need to consider many factors, such as scalability, security and cross-platform development. Moreover, this choice will also help you hire the right professionals, if you plan on outsourcing the development of your app.

UI/UX Design

The next step of the developing phase is UI/UX design. UI and UX are really important for creating an app that is easy to use and visually appealing. The UI/UX phase is structured into four main steps:

Information Architecture (IA) is the visual representation of the app’s infrastructure, features and hierarchy. The designer determines what content needs to be included and decides how it should be presented. It’s an essential step to ensure that the navigation is seamless and the app is easy to use.

Wireframes are visual representations of an app’s user interface and show the layout and placement of various design elements, such as buttons, icons, and images. They are typically the blueprint for the final design and ensure that the design is consistent with the app’s functionality.

Style guides include guidelines for typography, color schemes, imagery, etc. These guidelines ensure that the app’s design is consistent and on-brand, regardless of who is working on the project.

Prototypes are a functional representation of the app. They include the app’s features and functionality, allowing users to interact with the app and provide feedback. Prototypes help the development team to identify any usability issues before moving to the app development stage.

App Development Process: Backend and Frontend

Once you’ve finalized the design, it’s time to develop the app. The app development process involves both backend and frontend development.


The backend refers to the server side of the app, including the database, APIs, and server infrastructure.

Backend development typically involves the following stages:

  • Define the data model: This involves designing the database schema and defining the relationships between the data entities.
  • Develop APIs: APIs are the endpoints that the frontend uses to communicate with the backend. The development team needs to define the API routes and methods and implement them using a web framework like Express or Flask.
  • Implement security: The backend must implement security measures to protect user data from unauthorized access. This includes measures like encryption, hashing, and secure authentication and authorization.


The frontend refers to the client side of the app, and it includes all the elements the user can interact with, such as the interface, navigation, and user experience.

Frontend development can be platform-specific (so, for example, just for iOS or Android) or cross-platform and it typically involves:

  • Develop the frontend logic, that is implementing the app’s functionality using a frontend framework like Angular or React.
  • Implement security: the front end must also implement security measures to protect user data from unauthorized access. This includes measures like HTTPS encryption and secure token management.


Before deploying and launching your app, it’s important that you test it. Testing is a crucial part of the app development process, as it helps identify and fix bugs and ensure that the app functions as you want.

You need to apply testing to different levels:

  1. Unit testing: testing individual components of the app to ensure that they function as intended.
  2. Integration testing: testing how the different components of the app work together.
  3. Performance testing: testing the app’s performance under load, to ensure that it can handle high levels of traffic and usage.
  4. Security testing: testing the app’s security measures to ensure that user data is protected from attacks.
⚠️ While you test, make sure you’re complying with legal requirements too!

Apps need to meet specific requirements.

We’re now at the end of the app development process. Once the app has been developed and tested, it’s time to deploy it to a production environment. Then you’ll need to submit your application to the app stores, such as Apple’s App Store or Google’s Play Store, which will review your app and either accept it or decline it.

Did you know?

One of the reasons your app could be rejected it’s that it’s missing a privacy policy! App stores have tightened their requirements, and apps that don’t meet security and privacy standards may be rejected.

But don’t worry, creating a privacy policy for your app is really easy with iubenda. With our Privacy and Cookie Policy Generator, your privacy policy is just a few clicks away!
