1. About Mobile App Development

To simplify, a mobile app is a software application designed to run on mobile devices, such as a smartphone or a tablet. 

Mobile apps can be classified into a variety of types, but there are 3 common types, including:

Native App

A native app is a mobile app that is developed specifically for a particular mobile operating system, such as iOS or Android.

Native apps are developed using the programming languages and frameworks that are native to the mobile operating system. However, one code is developed specifically for only a mobile operating system, and will not work on both platforms. 

Hybrid App

Hybrid apps are used on multiple mobile operating systems, such as iOS, Android and Windows. They are typically developed using cross-platform development languages, including Flutter, React Native…  

Progressive Web App (PWA)

A progressive web app (PWA) is a type of web app that combines the best of both worlds: the user experience of a native app with the reach and flexibility of a web app. 

PWAs are built using web technologies, such as HTML, CSS, and JavaScript. PWAs are still a relatively new technology, but they are quickly gaining popularity.

2. Structure and Roles of Mobile App Development Team 

To develop a successful mobile app, the first and foremost step is building a team responsible for creating and maintaining the mobile apps. Each team member plays an important role in the development process, working together to make sure the app is created and worked well.

A mobile app development team typically includes the following roles:

Product Manager

The product manager is responsible for the overall vision and success of the mobile app. They work with stakeholders to define the product requirements, features, and timeline. They also oversee the development process and ensure that the app meets the needs of the users and the business.

Project Manager

The project manager is responsible for planning and executing the mobile app development project. They oversee the team’s progress, manage the budget, and ensure that the project is completed on time and within budget.

Business Analyst

The business analyst works with the product manager to understand the business needs and requirements for the mobile app. They also help to define the app’s scope and features.

UI/UX Designer

The UI/UX designer is responsible for the design of the mobile app’s user interface and user experience. They create wireframes, prototypes, and mockups to illustrate how the app will look and function. They also work with the developers to ensure that the design is feasible and implementable.

Mobile App Developer

The mobile app developer is responsible for writing the code that makes the mobile app work. The developer team can be divided into three types: iOS Developer, Android Developer (or React Native Developer for developing cross-platform app), Backend Developer. They use programming languages to develop the app’s front-end and back-end. They also work with the UI/UX designer to implement the design and ensure that the app is performant and bug-free.

Quality Assurance Engineer

The quality assurance engineer is responsible for testing the mobile app to ensure that it meets the requirements and is free of bugs. They use a variety of testing methods, such as unit testing, integration testing, and system testing, to verify the app’s functionality and performance.

The size and structure of the mobile app development team will vary depending on the complexity of the app and the size of the organisation. However, each team member’s contribution is essential to the success of the app. 

3. Stages of a Mobile App Development

The stages of a mobile app development team can vary depending on the specific needs of the project. However, the typical stages will include:

Ideation and Requirements Gathering

The first stage of mobile app development is to ideate and gather requirements for the app. This involves brainstorming ideas, identifying the target audience, and defining the app’s features and functionality.

The team can start by brainstorming a list of potential app ideas, and then start to narrow it down to identify a promising app idea. After that, they can start to gather requirements. This involves working with stakeholders to identify the specific features and functionality that the app should have

Planning and Design

Once the requirements have been gathered, the team develops a plan for the development process. This includes creating a timeline, budget, and risk assessment. The team also creates a design for the app’s user interface and user experience.

The team can create wireframes, prototypes, and mockups to illustrate the app’s design. They can also get feedback from users on the design before starting development.


The development stage is where the team writes the code for the mobile app. This includes developing the front-end (user interface) and back-end (server-side) of the app.

The team will use a variety of programming languages and tools to develop the app. The specific languages and tools that they use will depend on the platform that the app is being developed for.


Once the app has been developed, the team tests it thoroughly to ensure that it meets all of the requirements and is free of bugs. This includes unit testing, integration testing, and system testing. The team can use automated testing tools to help them test the app.

Deployment and Maintenance

Once the app has been tested and approved, it is deployed to the app store. The team also provides maintenance and support for the app after it has been released.

4. Tech Stack of a Mobile App Development Team

The tech stack includes programming languages, frameworks, tools and other software components. There are a lot of technologies used for building an app, but they can be divided into two main categories:

  • Front-end: In case you don’t know what front-end means, it is the part of the app that users interact with. It is responsible for displaying the user interface and handling user input.
  • Back-end: The back-end is the part of the app that runs on the server. It is responsible for storing and retrieving data, processing user requests, and generating responses.

The following are some of the most popular technologies used in mobile app development:


  • Programming languages: Java, Kotlin (Android), Swift, Objective-C (iOS), React Native (cross-platform)
  • Frameworks: Android SDK (Android), UIKit, SwiftUI (iOS), React Native, Flutter (cross-platform)
  • Tools: Android Studio (Android), Xcode (iOS), Visual Studio Code (cross-platform)


  • Programming languages: Java, Python, Node.js, PHP, Ruby
  • Frameworks: Spring Boot, Django, Laravel, Ruby on Rails
  • Databases: MySQL, PostgreSQL, MongoDB, Redis

The specific technologies that are used in a mobile app development project will depend on some factors, such as platform, type of app, complexity of the app, budget…

5. Ways to build your mobile app development team 

There are three main ways that businesses can use to build a mobile app development team:

  • Outsource: Outsourcing involves hiring a third-party company to develop the mobile app. This can be a good option for businesses that do not have the in-house expertise or resources to develop the app themselves.
  • Freelance: Businesses can also hire freelance mobile app developers. This can be a good option for businesses that need to develop a simple app or that need to add specific features to an existing app.
  • In-house: Businesses can also build their own in-house mobile app development team. This can be a good option for businesses that need to develop complex apps or that need to have complete control over the development process.

Each of these options has its own advantages and disadvantages, you can quickly check by reading the table below:

Outsourcing– Cost-effectiveness
