Roles and Responsibilities of a Mobile Application Developer


According to Statista, there were more than 204 billion apps downloaded worldwide in 2019. Each of these apps, no matter the size, quality, or style, had to undergo to make it as far as they did.

When it comes to these development processes, many companies turn to their mobile application developer. This individual has a variety of roles and responsibilities that they need to fulfill for an app development project to go smoothly. Without these tasks done, the quality of an app and its rollout are sure to suffer.

Mobile application developers are a crucial part of the mobile app development process. They are often called upon to complete tasks ranging from the very planning stage of an app and into its full release. This ensures that the apps are well-planned and well-executed.

What Does a Mobile Application Developer Do?

Project Timelines and Workflows

When someone hires an application development company, they want to know how long it will take to finish their app. This timeline is, in part, determined by the mobile application developers. That’s because this position is often in charge of creating workflows and project schedules. This is a crucial piece of management because a group of people working on an app needs to know their specific responsibilities and when to do those tasks for a project to go smoothly.

Act as a Liason Between Departments

Mobile app development demands a lot of different areas of expertise. For example, while technical developers are crucial, they need to know what to create. This can come from sources such as product development teams or research and      development marketing departments.

As a mobile application developer, an individual is responsible for coordinating these conversations and making sure that everyone is on the same page. This helps the process to go smoother and run more effectively.

Introduce Expertise On Different Platform Types

Rather than focusing on a single platform, many companies choose to create apps for their consumers no matter what device they’re using. Even many companies that rely on native app development may have a version to support Android and an option for iOS. This is why a mobile application developer must be familiar with multiple platforms. This is what helps companies expand their portfolio and entrust their software development to someone familiar with all their options.

Testing and Debugging

This part of a mobile application developer’s job is making sure that a finished app doesn’t have any bugs or glitches in it that would turn customers off of it. Before any app reaches the market, developers have to extensively test it and refine it to ensure that customers don’t run into any glitches while they try to operate it.

Supporting App Releases

Once an app is completed and tested, it still needs to be rolled out to the public. This is a step that takes careful planning and execution to pull off properly. Mobile application developers’ jobs often don’t stop after the initial development period. Instead, they often extend into taking care of the app after it hits the market. This could include patches, updates, and even help in the marketing strategy for the game.


A mobile application developer wears many hats in their offices. This makes the role a valuable one for a versatile candidate. If you’re interested in multiple app development techniques as well as in more administrative positions such as managing the timeline for products and helping to assign tasks. You should also make sure you’re prepared to tackle post-release jobs such as updates and bug repairs.
