Skills required for a mobile app developer

How to become a mobile app developer? If someone was to ask this question, the answer would be to have the right skills. But what are those skills? Mobile app developers need both technical and soft skills to succeed in their field. Let us discuss these skills separately.

Technical skills

Here are some technical skills mobile app developers must have.


Since Android was launched in 2008, Java has been the default language for producing android apps. And while it has been replaced by Kotlin since 2019, the language is object-oriented and still prominently used in app development. It is also compatible with Android Studio. Therefore, it is considered a must-have skill for mobile app developers. Java is incredibly reliable when developing high-security apps. 


After 2019, Google backed Kotlin as the default language for Android apps. This makes it an essential skill for mobile app developers to possess. Kotlin is a cleaner and simpler version of Java. It is intuitive, compatible with Java, and allows errors to be identified in the early development phase. 

Language programming skills

Mobile app developers must have advanced programming skills with in-depth knowledge of languages, including C++, JavaScript, HTML5, CSS, and Python. Having these skills ensures that you can build functional apps. The good thing about learning these languages is that you can learn them online through a course or certification. 


React.js is used for devising good-quality user interfaces. Having the skill to build high-quality user interfaces is essential to generating high traffic. Since React.js is a JavaScript library, it saves time and helps developers quickly debug. 

Back-end development skills

Another essential skill, having the knowledge of backend development, helps identify and fix any system issues before public release. Mobile app developers often use back-end technology like framework, database management, hardware interaction, and security. This also helps them in developing logical and computational application software concepts. 


Angular is what Google is based on. Its features are advanced enough that it can help in quick and effective development. Angular is reliable and enables you to create large-scale apps with high-quality performance, making it a good skill for all mobile app developers. 

UI design

User interface (UI) directly impacts the user experience, making it the most important part of mobile app development. Everyone wants to build a high-quality app that results in many downloads. And this is made possible with a simple, unique, consistent user interface. Therefore, this is the skill that mobile app developers must excel in.

User experience design (UXD)

User experience design (UXD) helps make mobile apps more efficient and provides a smooth user experience. UXD involves using users' behavior data to create interaction between humans and mobile apps. It is crucial to creating user satisfaction. 

Cross-platform application development

The different number of mobile platforms is increasing continuously. Therefore, developers must have the skills to manage cross-platform application development. The three primary mobile operating systems include Android, iOS, and Windows. A thorough knowledge of cross-development concepts, such as service support, reusable codes, and simple testing, can help you stand out from the competition.

IoT skills

Having IoT skills is also beneficial for mobile app developers. It helps them develop complex apps and their associated business systems. Since IoT capabilities require high-level expertise, having these skills also boosts your career.

Agile development

Mobile app developers often work as a part of the Agile work environment. Agile helps in the efficient development process. Having the knowledge of Agile development can help you advance your career and even lead your team with Agile. 

Soft skills

Mobile app developers must also possess soft skills, such as communication and interpersonal skills, teamwork, collaboration, and problem-solving. 

  • Business analysis: Having business analysis skills means having the ability to translate a client's vision into development requirements. This helps in performing efficiently and effectively.

  • Communication: As a mobile app developer, you often communicate with clients and other team members. Therefore, you must have good communication skills to understand and meet the client's needs. 

  • Manage deadlines: Mobile app developers often work on multiple projects under a strict deadline. Therefore, you must have the skills to multitask while managing deadlines.
