What is the mobile app development process?

More than 200 billion mobile apps are on the app stores developed for different platforms.

Just like SDLC (Software Development Life Cycle) in software development for PCs, there's MADC (Mobile App Development Cycle) in mobile application development to develop highly-interactive mobile apps.


Creating an excellent mobile app is a process associated with extensive pre-planning. The mobile app development process involves a strategy, design, and development process. With that said, here's a look at the app development lifecycle, objectives, and the challenges encountered along the way.

1. Idea

To build a great app, you need to have a good idea first. Without a good idea, you can't continue with app development.

You have to ask yourself questions by keeping the app idea in mind that entails the users' problem and how to solve it.

You need to analyze the problem and figure out why no one else has built the app for that problem. Speaking with other people about the app idea can help you get the appropriate results.

2. Strategy


After having a perfect idea, you need to figure out who your competitors are and what they are currently doing to attract users and make a strong customer base.

You will have to find out the number of similar apps installed, you need to check its reviews and ratings, and you also need to check the app and background history.

There are two main objectives of this process:

  1. Learn as much as you can so that there are minimal mistakes.
  2. Find out how fierce the competition is in the market and how many users are eagerly looking for such apps. Then, try finding out your competitor's niche and convert it into a benefit for your app.


App monetization is an essential step in your app development strategy. If you want your app to make money, you will have to make an app from your user's point of view.

There are various methods of monetization like subscriptions, in-app purchases, ad revenue, premium features, paid apps, and selling users' data.


App marketing is all about finding the challenges in the market while launching your app. It's like planning for the 4ps that include product, price, place, and promotion before starting a product or service. Remember that there are a lot of applications on play stores that are beautifully designed and crafted but are unused.

So, first, you will have to find out the potential usage of your application. For example, you need to figure out solutions to questions like how many people download apps similar to yours. Other than this, will your application be able to solve their problems?

You need to understand your approach and the overall budget.

Road Map

It is the last stage of the app development strategy. Preparing your app's roadmap includes understanding its future and the steps needed to make it successful from day one.

Here, you need to prepare a list of all the tasks your app will perform and rank them according to the priority. As you gain users, you will know what functionalities need to be added.


3. UX Design


This process will decide what functionalities and information you need to keep in your application to organize them.

You need to prepare a list of all the tasks that your app will perform and rank them according to the priority and what is required to be displayed in the app.

You will need a whiteboard, pencil, and paper.


In this stage, you document and wireframe the application to analyze the future trends.

Wireframing is significantly something beyond just creating an app architecture; in reality, it's a pillar of your application.

Wireframing helps you understand the system's flow and gives you an idea of how it will work. Further, this enables you to estimate the project development timeline.

Requirements: AdobeXD/Sketch, whiteboard, marker, Balsamiq, and paper.

Learn more about the Role Of Wireframes In Mobile App Development.


Workflow is the path on which your mobile app users travel. Understanding your user's activities and monitoring how many clicks are needed to perform that task. When you find any problem within the workflow, you need to wireframe that section again and retry.

Requirements: You need invisionapp, whiteboard and marker, and paper.


4. Development

After putting considerable effort into the application design and structure, you now realize your vision.

In this step, you will define the tasks to the developers to achieve the defined objective of a mobile app

The best part is you can see the progress of your mobile app with the help of project management tools such as Trello and Basecamp, where every activity is being recorded and tracked appropriately.

5. Q/A testing

Q/A testing is generally carried out by non-developers or any developer in the app development team. It guarantees a genuine and quality app testing experience. Several types of tests need to be emphasized during each sprint. The test types are

Functional Testing

Functional testing is done to test the app against the functional specification/requirement of the client.

App test engineers use the information gathered at the initial requirements analysis stage to test an app as their test cases. It helps them check whether the project is going as expected.

Performance Testing

No one will use your application if it takes 15-20 seconds to display a list. This is the reason app performance testing is essential.

Performance testing tests the system for stability and scalability under various load conditions.

It also detects potential web constraints to examine the structure and operation under high stress. The primary aim of this testing is to ensure that the system is performing well and behave well when utilized by the users.

Usability Testing

Usability Testing ensures that the features of an application are intuitive and user-friendly.

In usability testing, a system's HCI (human-computer interaction) factors are measured, and flaws are identified for further improvement.

At this stage, the development team monitors the user's screen to know how the selected user is interacting with the website.


What languages are used for mobile app development?
