Mobile App Development Process from Idea to Launch

Mobile app development is a fairly standard and straightforward process. It includes strategy, design, development and deployment, pretty much like any other software development project.

However, if you have never been involved in software development before and start building an app for your business, you may find it a bit lengthy at some point. Why does the design take so many steps? Why do we need to test all the time? And what are these iterations after all?

Knowing the specifics of the mobile app development process from day one will save you a lot of questions and make your experience more engaging.

In this article, we will walk you through the basics of app development from idea to launch, and beyond.

In this article:

  • Mobile apps development process step by step.
  • The real story of transforming a mobile app idea into a working system.

Mobile applications development process step by step

There are several stages of app development that cover strategy, design, development and deployment. We break this process down into 7 steps and describe each of them in detail. It will help you understand how your mobile app evolves from an idea to a working application available on app stores.

Step 1. Articulate idea

Every mobile project starts differently. Many clients come to us only with an idea. Others already have some documented requirements or a list of features they want to see in an app. There are cases when a client needs to build an app similar to some existing system. For example, when a company uses a web platform and needs an app to create a seamless cross-device experience for customers or staff. And it’s not unusual to get a request for an ‘app like Uber Eats’ or something like that.

Whatever the case, our main goal from the very start is to learn as much as we can about the concept of your app. Who will use it? What platform/platforms we build for? Are there similar systems in the niche? What are the business objectives of this project? Do you have a marketing strategy in mind?

At this step, we conduct a series of interviews and ask these and many other questions to get a clear idea of project goals, context and timeline. Ideally, we engage different key stakeholders on your side such as a product owner, designers, your marketing team and domain experts, etc. This approach allows us to cover as many aspects of the project as possible, hear your expectations, dive into your business and market environment.

Once we gather the requirements and have all the information, we move to one of the most important parts of an app development cycle — analytics and research.

Step 2. Research

This is a crucial step in any new product development. The better you do your research, the more refined your product strategy will be. It helps reduce mobile app development costs and saves a lot of time during the rest of the development process.

As a rule, we conduct our research in several directions:

    • Audience. We learn what we can about the future users of the app — their expectations, challenges, goals, habits, behavioral specifics, tech skills, device preferences. This information is essential to create user personas later at the design stage.
    • Competition. It never hurts to know what others offer in your niche. We analyze the competition to see how other companies solve similar challenges, what technologies they use, what features they have. We find out what they do good and what can be done better. This analysis helps understand the market and find opportunities for your competitive advantage.
    • Industry. Every domain has its own standards, rules, technologies, monetization practices and simply the ways things work. We study industry specifics and bring in cross-industry expertise where it is reasonable. The results of this analysis will have a huge impact on the design and technology choices.
    • Business and technology. We learn about your business, technology infrastructure and operations related to the future mobile app. Thus, we will be able to select an optimal tech stack and design mobile experiences that will reflect your brand’s identity and be consistent with other services you provide.

Based on all the information we gather during interviews and our research, we can prioritize requirements, select tech scope and create a product development roadmap.

Step 3. UX design

discovery phase

User experience design is, probably, the most exciting part of the mobile application development lifecycle because it gives you the first glimpse of how your app can look and work. At this step, we determine how users will experience the application and interact with the system.

UX design itself is a multistep process. We will give you a simple breakdown, but if you want to dive deeper into it, check our article about the design process and techniques.

Do you remember how we started our research by analyzing the target audience? Now we need this information to create personas. Persona is a collective image that describes one user group with similar goals, intents, behavior, tech skills, etc. Using personas, we can design experiences that address the needs of different target audiences.

User scenarios

User scenarios describe how every persona will experience the app. If we put different scenarios together, they form scenario maps that illustrate many ways how every persona can and will use your application.

Information architecture

Information architecture (IA) demonstrates the structure and preliminary layout of the app’s interface. It gives you an idea of what will be on different screens, how they are connected and how users will navigate throughout your application.


Paper and whiteboard sketching is a very creative and collaborative process in developing an app. The goal of this step is to explore different design versions for each screen and interaction. Different team members, not only designers and project management but also developers, BA and QA, can take part and contribute. It is usually an extremely busy process with zillions of suggestions and dozens of iterations, hence, markers and stickers to make it quick and simple.


Black-and-white wireframes have every detail of every screen of your app except for color, real imagery and content. At this step, we can already do some early-stage testing and click through the black-and-white screens using prototype tools like Marvel.

Step 4. UI design

high-load system development

At the UI design step, we turn black-and-white wireframes into engaging and colorful mockups. Needless to say, it’s a very satisfying stage in the mobile application development process. Now you will get to see how exactly your app will look when a user opens it on his or her mobile phone.

This process may start with mood boards, a collection of design elements, color scheme samples. That is, of course, if your app represents a whole new brand and we are starting from scratch. If you have a brand book, a style guide or other branding materials, then the main goal of a UI designer will be to carefully translate the unique identity of your brand to the new app looks.

By the end of this phase, you will have a colorful high-fidelity prototype of your application in Figma or any other design tool.

UI design is the last step of the design phase. But don’t be surprised if we have to get back to the mockups and make some tweaks later during development and testing. The great thing about the iterative development approach is that we can test our assumptions and design ideas and make corrections based on the early feedback long before the system gets to the hands of end-users.

Step 5 Development and testing

flutter app development

The next step in the app development cycle starts with handing the finished and approved UI design to the development team. It is important that this transition runs smoothly and designers and developers can communicate and clarify the details before the coding starts. After all, the goal of the development team is not only to build a functional application but also to make it pixel-perfect and engaging.

The team’s skill set will depend on the specifics of the application. If we are building two native applications, we engage both iOS and Android engineers. Cross-platform mobile apps built with modern frameworks like React Native or Flutter usually run on one codebase and can be developed by one engineer. However, if an application requires complex backend development, we may need to add extra competence and skills to the project. And of course, we can’t build a sound application without a QA engineer.

Development is the longest phase. Fortunately, it is also the most rewarding part of the process. Mainly because you will finally be able to try your application. But also because you can watch closely how it grows and test in-development versions every once and a while.

Agile development

Agile development methodology is an industry-standard and time-proven approach in software development. Before we start coding, we break down the whole development process into a series of cycles, each of which includes development, testing and review. In every cycle, we develop a batch of features, test the implementation, fix issues and make a review. If we find out that something doesn’t add up or requirements change, we can rapidly realign the development plan without causing serious delays and costly changes.

Aside from flexibility, this approach provides incredible transparency both for you and for the development team. You see how the application evolves, iteration by iteration, and can step in with comments and suggestions at any time.

Frontend development

When we are talking about frontend in the app development process we mean building a client application that will be installed on the users’ phones. In other words, we bring the UI design to life and make it work.

Mind that we are going to run the code on a mobile device with limited memory capacity and battery life. Therefore, we have to make a lot of decisions that will influence the performance of the app. For example, we need to figure out how much processing should be done straight on the device to enable a near-instant response to user commands (e.g. image editing features) or seamless performance in offline mode (e.g. industrial applications). At the same time, we decide on the logic and data management that will run on the server to lighten the app and provide better scalability.

Backend development

Backend development includes all the server-side engineering. As a rule, the groundwork for the backend architecture is already laid down in the tech scope.

Depending on tech specifications and functional requirements, we may need to build or integrate the tools to manage the app’s content (content management system), store and pull user data when necessary (database), work with third-party systems and other software you may be already using (widgets, APIs). In many cases, we need to engage third-party cloud services to host and maintain the app’s infrastructure.

Another important part of backend development is ensuring strong data security, including user data safety (particularly important for healthcare mobile app features), secure authentification methods, encryption technology, etc. In 2021, poor data security practices may cost a company millions of dollars in fees.


Quality assurance is an integral part of every development cycle. There are several types of testing implemented during app development. There are functional and performance tests that help ensure everything works as it should, the app is fast and can handle the load. Usability tests focus on user experience. We also test the application on different devices and device simulators to check how everything renders on various screen sizes.

Step 6. Deployment and launch

By the time we approach the final app development stages — deployment and launch  — we make sure your application is sound and well-performing. If possible, we conduct testing and reviewing not only with the stakeholders but also with potential users who can give us early feedback.

As soon as we get an all-clear, we can add an app to the store or stores. You will need to make a developer account (as an owner of the app) if you don’t have one already. We follow several standard procedures such as adding app screenshots, providing descriptions, etc. If everything goes smooth and the store reviews the application right away, the process won’t take longer than several days. It is possible to get comments or requests from app store representatives. Then, the launch may be postponed till everything is sorted out.

For a consumer-focused application, you may need to have a web landing that promotes the application and provides links to the stores where the app is published.

Your application is on stores, you get first reviews and installation statistics. It may seem that your journey is over, but in most cases, it is not.

Step 7. Monitoring and optimization

mobile development process

It’s important to monitor your app’s performance after launch, go through user reviews and sometimes even interact with the end-users to see if there are any issues with the app’s usability. Nothing beats real user feedback.

Depending on your goals, you can define certain KPIs and engage app analytics tools for monitoring. After a while, you will gather sizeable feedback that will help you define the strategy for further app optimization.

App development cycle using a real example

Let’s go through the mobile app development lifecycle using a real example. We’ll take Doña Shine and Doña Rise iOS applications for wellness to show how an app idea transforms into a fully-functional mobile application.

The apps connect yoga instructors with their students the same way Airbnb connects homeowners and travelers. It has Salesforce CMS, in-app payment and scheduling features, Twilio-based video sessions and integration with Apple Watch for notifications.

After the first release, we have performed a series of updates, added new features and scaled the apps’ geo from 2 to 23 countries. We can therefore say that this particular case shows the complete mobile app development cycle — ideation, design, development, testing, launch and post-launch update.
