What does an App Developer exactly do?

When you think of an app developer, you may think of someone who codes all day and survives mainly on caffeine. But there is so much more to them. So who is an app developer and what do they exactly do?

Well, an App Developer is a software engineer who creates, tests and programs apps for computers, mobile phones and other electronic devices. They understand coding languages and how to use them. Additionally, they test and fix any bugs that may be found in the app. Their job involves working in teams, testing applications and designing prototype application. But of course, the roles and responsibilities may vary depending on the client and the organisation they work for.

Major programming languages an app developer needs to know

This can vary based on platform and purpose. From low-level languages like C to cross platform app using Javascript and HTML/CSS, huge variety of languages are used while working on an app.


In the beginning, Objective-C was used as Apple’s official programming language for apps running on mobile and Mac OS. A general-purpose and object-oriented programming language, Objective-C adds Smalltalk-style messaging to the C programming language.


Recognizing a need for a more modern programming language, Apple switched to Swift, an improved, easier-to-learn successor to Objective-C. Swift codes are more easier to read and resembles natural English language more closely.


Java is the choice of programming language for Google’s Android, the other major mobile operating system. It enables mobile developers to build code that can run in multiple environments. This allows developers to create and reuse code that runs on virtual machines, browsers and different platforms which accelerates app development and deployment processes.

Dot Net

Microsoft developed the Dot Net framework that runs primarily on Microsoft Windows. It includes a large class library named Framework Class Library and provides language interoperability across several programming languages.


Python is used to quickly test and debug code. This language is effective for writing scripts that bind existing software components. In addition, Python is used in web development. In comparison to Java or C++, programmers can do coding in fewer steps in Python. 


HTML5 is used to build web-based apps which features multimedia support, full functionality across platforms, devices and browsers. This language provides developers with substantial flexibility since it can be used for both iOS and Android.

MEAN Stack

MEAN Stack makes it possible to use traditionally a front-end programming language – JavaScript, for back-end Web development. It is a collection of JavaScript-based technologies used to develop web applications i.e. MongoDB, Express.js, AngularJS, and Node.js.
