What is the mobile app development process? 

There are more than 200 billion mobile apps 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 what the users' problem is and how you can solve it.

You need to do an analysis of the problem and need to 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 is a minimal amount of mistakes.
  2. Find out how fierce the competition is in the market and how many users are eagerly looking for such apps. Try finding out the niche of your competitor 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, then 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 by selling user's data.  

You need to do proper market research to find out the latest trends if you want to monetize your app.

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 of any 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. You need to figure out solutions to questions like: How many people are downloading apps similar to yours? 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 app development strategy. Preparing a roadmap of your app includes understanding of your app future and steps needed to make it successful from day one.   

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

3. UX Design  
In this process, you will decide what functionalities and information you need to keep in your application and how they will be organized.

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 flow of the system 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 Role Of Wireframes In Mobile App Development.


Workflow is the path in 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. 

NMG has created a video on invision. You can add it here to make readers the workflow of the tool.  

4. Development  

After putting a considerable effort in 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

Languages: Kotlin, Java 
Database: Realm, SQLite 
Tools: Android NDK, Android SDK 
IDE: Android Studio 

Technologies for iOS Development  
Languages: Objective C, Swift 
Databases: CoreData, Realm, SQLite 


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. There are several types of tests that 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 that was gathered at the initial stage of requirements analysis to test an app as their test cases. It helps them to check whether or not the project is going as expected.  

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

The purpose of performance testing is to test the system for stability and scalability under various load conditions.   

It also detects potential web constraints to examine the structure and operation of a website 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, HCI (human-computer interaction) factors of a system are measured, and flaws are identified for further improvement.  

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

What languages are used for mobile app development? 

In the last five years, the mobile application development industry has multiplied in leaps and bounds, changing the way businesses operate around the world. There's one thing sure behind their success, the idea and implementation of the mobile app.
