6 Best Programming Languages for Mobile App Development

what should I learn for app development?

2020 was expected to be a great year for smartphone app development.

With the spread of the Covid-19 pandemic, it has become imperative for innovators to build more digital solutions such as “smartphone applications” to help people and develop the economy.

The smartphone application is the best way to start with establishing your company or growing your existing business and giving it a digital advantage.

Studies have shown that companies with a smartphone application attract customers better and generate more revenue.

Now that we have identified some of the reasons why you should stop thinking and start developing smartphone applications, it is time to act.

To bring your smart application idea to life, all you need is a smartphone application programming language that has the following:

  1. Easy to learn.
  2. Futuristic.
  3. Scalable.
  4. It contains certain features that help in developing high-performance smart applications and make the developer’s life easier. But how is that done? We will answer here…

There are dozens of programming languages ​​for smartphone applications.

Here is a list of the top 6 languages ​​which will help you to develop a great smartphone application, we have divided them according to the type of application you want to develop (iOS, Android or Hybrid) which will make the choice easier for you.

Best programming languages ​​for developing native Android applications:

1- Java:

After 25 years, Java is still the most popular programming language among developers.

One of the biggest reasons that make it the first choice for all smartphone application developers is that it is easy to learn and start with, in addition to that it provides broad community support that constitutes additional assistance to new developers.

Java is a programming language full of energy for smartphone applications, and some of the best Android applications have been developed using it, including Spotify and Twitter, in addition to the Android operating system through which you will be able to develop all Android applications easily, once you master the Java language.

Some of the best Java features include:

  • The simple and easy-to-understand Java architecture is more readable than Python and other programming languages ​​used to develop smartphone applications.
  • Being a programming language aimed at individuals, it deals with the complexity of real-world applications better.
  • Thanks to its rich API, Java allows you to integrate more into your smart application.
  • Java’s rich community helps new developers to improve their skills and assists them immediately when stumbling at any stage of their work, providing them with quick answers and sufficient detail.
  • Java is a strongly written programming language, which means that it will pick up any errors that you would make as a beginner.

Briefly; Java is one of the best programming languages ​​for developing smartphone applications, especially if you are a beginner in the field of smart application development and you need an Android programming language to help you.


When Google announced Kotlin as a 100% first-class language for developing Android smart applications, smartphone application developers around the world realized that programming languages ​​were on their way to update for the better.

Kotlin takes the best of Java’s features and goes further towards being newer and more comprehensive.

And the things Kotlin’s smart app developers love most are:

  • Easy to use and set up.
  • open source.
  • completely free.
  • Works on all platforms.
  • Supports almost all development environments.
  • Fully interoperable with Java (if you have some code written in Java, you can just as easily use Kotlin to keep track of your work without affecting any factors).
  • It is one of the cleanest programming languages ​​written for creating smart applications.
  • Kotlin’s documentation is very easy, detailed, and fun, which makes for a great learning experience as you start your journey with it smart APIs.
  • The Kotlin community is a large community that contains some well-known experts who are available frequently on GitHub and other forums, and they are always ready to answer inquiries from other developers.
  • There is a Kotlin Slack group where you can get your questions answered by some of the best-known developers.

Kotlin makers have made sure that developers’ concerns are at the forefront during language development, including:

  • Safe Nullability System.
  • Easy access to resources.
  • Lambdas.
  • Built-in variability / stability system.
  • The broadcast players are easy to use.

They are just a few of the features that developers always need, which makes Kotlin the best programming language for Android.

Best programming language for iOS native app development:


The initiative through which Swift was created by Apple was “Anyone Can Code”.

Soon after its launch in 2014, Swift saw massive popularity, and it was ranked as the most popular programming language for Stack Overflow in 2015.

At that time, Apple said that its goal from Swift is “complete and total domination of the world,” describing it as a “modest goal.”

Now, after about six years, we can already see Apple reaching this goal, as the Apple App Store contains nearly 500,000 apps partially written in Swift.

If you are looking to start developing smartphone applications, Swift is the best programming language to use.

And some of the best smart apps use Swift as the primary programming language for iOS apps, including Uber, Lyft, Square, and Airbnb.

Going back to Stack Overflow’s extensive developer survey, Swift programmers make an average of $ 120,000 in annual salary.

And for anyone thinking of learning to code, Swift is the best iOS programming language ever, it is:

  • Quick.
  • Easy to learn.
  • Specially created to be easy to use.
  • It has built-in design features that give you real-time feedback, which helps you reduce errors and keep your code clean.
  • Swift allows you to write code faster as it reduces the number of tasks that slow down developers.
  • Allows you to convert complex code into improved syntax, making developers comfortable in the work.
  • Provides a number of built-in tools that help facilitate development.

Swift Playgrounds is an app specially designed by Apple to help beginners learn to code easily with community experts who want to teach others.

And you can use this app to learn programming from scratch in a very engaging and interactive environment.

4- Objective-C:

Although Swift has largely become the programming language used in developing iOS smart applications, Objective-C is still the most used by many developers.

Objective-C is a comprehensive set of C (the oldest computer programming languages), and this makes it very compatible with C and C ++ codes.

Despite its existence for more than 30 years, it is still the best choice when it comes to iOS programming languages.

It has an unparalleled level of maturity as an old, approved, and well-tested programming language in hundreds of successful smart applications.

It is a very dynamic language, allowing you to choose between static and dynamic writing.

Moreover, connecting it to your smart API is easier and faster.

Also being an oriented language, it provides you with a great deal of adaptability at runtime and enables you to access your own APIs, making programming faster and simpler.

Objective-C is one of the most stable languages, and it works great in a wide variety of applications and business types.

It is also less prone to error, as it has fewer errors and easier assembly than its counterparts.

Best programming language for cross-platform application development.

5-React Native (cross-platform apps):

They are apps that do not need to be created separately for Android and IOS. Therefore, you can create and deploy only one application on the two platforms, which will reduce your development tasks in half and increase your reach by double.

Some of React Native’s Features:

  • It is a powerful programming language.
  • Used to develop applications that are not limited to one platform only.
  • it has been used in the development of popular apps like Uber and Airbnb.
  • It allows developers to write sections of code and reuse them on various platforms. (After the code is published, they can easily adapt it to the respective platforms by simplifying the elements and detailing the nuances).
  • It contains a number of pre-built components in an open-source library. (Which means that components that have already been developed by others, then developed and uploaded to the library can be used easily, allowing a great deal of speed of development).
  • Provides a simplified user interface with a well-ordered execution command. (This makes its built-in apps more responsive, faster to download, and smoother to use).
  • A number of its supportive libraries facilitate tasks.
  • Offers third-party plugin support (if your e-commerce app needs calendar support, you don’t have to create a calendar from scratch, as React Native lets you search for a pre-made, available-to-use calendar that can be simply integrated into your app).

Modular architecture, live reloading, declarative programming style, and a number of other capabilities make React Native particularly suitable for smart application development.

And if you’re looking to build a cross-platform app that’s newer, faster, and cheaper, then React Native is a great programming language for smartphone apps.


Google developed it as a smartphone app SDK app.

Using the programming language Dart, provides developers with a fast and easy way to create rich, high-performance smartphone applications that can be easily deployed on both platforms.

It has a rich library of application building utilities, and thanks to its rich user interface elements, it creates smart applications across platforms that appear as seamless as native applications.

It enables faster code writing by taking full advantage of code reuse potential, meaning you can use as wide sections of your code as it is on both platforms. (All you’ll do is add some individually defined user interface elements to the app, and have a fully functional multi-platform app in half the time and cost).

One of Flutter’s successful achievements is Hot Reload (which enables you to see changes made to code in real-time during application change).

And if you want to modify any part of the app, or make it look or function differently, you can modify the code and see how the changes happen in real-time.

Because the code base is smaller and similar on both platforms, Flutter requires much less testing than its original counterparts.

Not only does Flutter contain a rich library of widgets to help you create amazing apps, but it also allows you to customize your own user interface elements, and truly get to know the rich original experience you want with a programming language used for smartphone applications.


The above was a simple description of the 6 best programming languages ​​for developing smartphone applications.

There is a number of other great programming languages ​​such as Ruby, Python, and HTML5.

But it is best in the beginning to choose the most popular languages, and get started with rather than spending a lot of time searching for 30 different languages.
