If the growing numbers of smartphone users are not enough to recognize the success of digital devices, I have no idea what else could be. We live in a fast-paced world where everything has become digitized and apps particularly have a major role to play in this accomplishment. We all seem to be excited and be in a transport of delight when it comes to using the apps. Simple snake game in Nokia 6110 is considered as the first mobile app for smartphones. Since then the journey of apps, be it native or cross-platform, has progressed beyond the perception. 

Though mobile apps have now become an “on-the-go” thing for users, how many of us ever tried to understand the science behind the app development and on what technology the applications actually work? Not most of us, right? The programming language is said to be the foundation of mobile apps. A product owner always relies on the renowned and trustable mobile app development company that employs the right language to develop a customer-oriented app for his business. 

In this blog, we are going to learn about 14 different programming languages that are useful for developers, either it comes to iOS or android app development.

  1. Java – It does not matter if you have been in the field of software development for a decade or just started off, you most probably have heard the term Java. Java is one of the most popular and preferred languages among android app developers. This is an object-oriented programming language used majorly for back-end project development.
  1. Javascript – JavaScript is a text-based multi-paradigm language that supports object-oriented and functional programming. JavaScript is considered the best programming language for cross-platform app development and makes web-pages interactive. This versatile and flexible language can be used in many ways by integrating it with Node.js.
  1. Kotlin – Kotlin is a general-purpose programming language often tagged as the advanced version of Java. Kotlin is one of the programming languages that come with Google and IDE’s installation packages. Many developers believe that Kotlin overrules the shortcomings of JAVA to a great extent. Evernote, Square, Netflix, and Zomato are some apps that have been built over Kotlin.
  1. C++ – It is better to term C++ as an extended version of the C programming language. Though both the languages share almost similar features, C++ is more extensive and unified between the two. C++ is a cross-platform language and therefore can easily be used in developing apps for Android, Windows, and iOS. C++ was developed by Bjarne Stroustrup.
  1. C# – Sounds and reads like one of the guitar chords, C-Sharp is another object-oriented programming language used majorly for cross-platform and windows app development. Major prominent gaming companies like Unity use its code as a scripting language. Hence, it is one of the most interactive and high-performance languages for developing game apps.
  1. Python – Python is a widely accepted and most-liked programming language among all. When it comes to comparing it with any other language, Python will undoubtedly come out as a clear winner. It is a programming language used for computing scientific and numeric data. Python has simple and readable syntax.
  1. Swift – Swift is a platform-oriented programming language specifically designed to integrate easily with iOS, OS X, and tvOS platforms. Swift can execute well on Cocoa and Cocoa Touch platforms. The syntax of Swift encourages developers to understand the language thoroughly and write consistent codes.
  1. PHP – The mobile apps that need database access are more likely built upon PHP programming language. PHP, which stands for Hypertext Preprocessor, is platform-independent and exceptionally compatible. PHP programming language can be used to build mainly all types of mobile apps.
  1. HTML – HTML, an acronym of HyperText Markup Language, is generally a markup language for web pages. HTML comprised of an element trail that are represented by <> tags. Now HTML has been advanced to the fifth version commonly known as HTML 5 which is compatible with all browsers. It is not a programming language and used for tags and attributes.
  1. Ruby – Ruby is a back-end scripting language that comes with intuitive code quality. Ruby is used for developing web-applications, servers, and standard libraries. It is one of the high-level programming languages which is easy to learn and execute for beginners. Ruby language has a dynamic type system with automatic memory management.
  1. SQL – SQL stands for Structured Query Language which is used majorly for relational databases. Since database management is a complex process, SQL standards are popularly known to rationalize complications of database management systems effortlessly. The developers do not need to write a copious amount of codes to comply with data access control.
  1. Objective-C – Objective C is another extension of the C language. Even though the market is now swamped with plenty of programming languages, Objective C still seems to dominate most of them single-handedly and manages to demonstrate its popularity among developers. Moreover, Objective C adds syntax that turns out as an advantage for an object-oriented language.
  1. Rust – A multi-paradigm programming language having syntax much akin to C++, Rust system codes are used for developing high-performance applications. Rust, sponsored by Mozilla, was created with the objective of enhancing the concurrency and safety of the system.
  1. Lua – Lua is considered a light-weight but high-level programming language commonly used for the scripting language. Lua is dynamically typed. The majority of the app developers use Lua for embedded applications. Out of many, Lua is one language that comprehensively tackles errors that flows while developing applications. 


As the several apps are gaining traction among users, the programming languages are not lagging behind either. In fact, it is rising in popularity with developers at an equal pace. Every programming language has its own strengths and weaknesses and this is what makes developers idiosyncratic when it comes to choosing the best among all.
