React Native vs Kotlin

Mobile app development has now become a cornerstone of successful market differentiation, growth, innovation, profitability and collaboration.  Several enterprises are now aggressively adopting mobile technologies to achieve business objectives. In order to meet the rapidly fluctuating business requirements and business needs, there are several different platforms and technologies.

It has become a point of debate to choose the right technology to accomplish objectives. More and more organizations are adopting cross platform mobile app development services to build  mission-critical mobile apps to expand the business.

If you are planning to launch a new mobile application, it is about time to compare two most favorable frameworks-React Native vs Kotlin to help you understand the advantages and drawbacks. This quick analysis will help to decide whether to opt for cutting-edge Kotlin Application development services or React Native development services.

React Native

React Native is a JavaScript framework developed by Facebook for writing real, native mobile applications for iOS and Android, as well as reuse code across web and mobile applications. Based on React, Facebook’s JavaScript library for building user interfaces which specifically target mobile platforms. This framework allows developers to build mobile applications that are truly native with their classic all-time favorite JavaScript.

Also, the code can be shared between platforms; React Native makes it easy to develop for both Android and iOS simultaneously. It uses the same design as React Native, letting you compose a rich mobile UI from declarative components.

Advantages of React Native

Native mobile application development using JavaScript and React

React Native lets you develop mobile application using only JavaScript. It uses the same design as React, which allows you build a feature rich mobile UI from declarative components.

Code Reusability
Working with React Native can reduce the requirement of resources needed to build mobile applications. Any developer who knows how to write React code can start developing for different platforms such as the Web, iOS, and Android. This provides the much needed flexibility to classify developers based on target platform. React Native lets team to iterate and utilize resources effectively.

Quick Learning Curve

REACT Native is an excellent choice for developers with expertise and familiarity in JavaScript as there is no need to learn Android specific Java or iOS’s Swift. This makes the learning curve easier and eliminates the need of maintaining different team for iOS and Android. Smaller team size effectively means less cost and easy to manage teams.

This framework helps meet the demand of both the platforms at one go and ends the perennial battle of selecting either iOS or Android app development for mobile developers.

Hot Reloading

React Native is heavily focused on UI which makes quick loading apps and gives a smoother feel. React Native lets you build your app faster. Now reload your app quickly as there is no need of recompiling. With Hot Reloading, you can quickly run the new code while retaining your application state.


Sponsored and developed by JetBrains, Kotlin is a programming language that runs on the Java virtual machine and can be compiled to JavaScript source code or use the LLVM compiler infrastructure. After being endorsed by Google as the official language for Android Studio, Kotlin has consistently gained popularity.

Backed by JetBrain, Kotlin is responsible for creating best IDE tools. Kotlin provides phenomenal support on different development environment such as Android Studio.  Selecting Kotlin app development for your Android project provides support across multiple tools and IDEs.

Kotlin code is not only precise and concise, but also has an extremely clear codebase. That leaves less chances for errors and allows stable code in production. You have to write fewer  lines of code to achieve the same functionality.

Advantages of Kotlin


Ever since Google endorsed Kotlin, this language has witnessed phenomenal growth and evolved in terms of providing stable support through different levels of testing before the final release. Android fragmentation is a one of the biggest problems faced by programmers. Kotlin, a programming language developed by programmers helps overcome several issues. Its reverse compatibility with the previous versions works as a blessing.

Less Code

Kotlin is concise and requires less or fewer lines of code for any given functionality. In simple words, fewer lines of code minimize chances of errors, improving maintainability and readability of code. This means Kotlin developers can write, read, and change code effectively and efficiently.


Java interoperability adds to the list of advantages of Kotlin.  The language works flawlessly with Java, including tools and frameworks, which constitute a feature-rich ecosystem.


React Native is a thriving community that offers a cohesive ecosystem for mobile app development sector, as well as access to libraries and plugins to ensure faster time to market. The apps enjoy the intuitive and robust features of native apps without compromising on the performance, all in a reduced timelines, cost, and resources.

On the other hand, Google recommends Kotlin as the standard IDE for Android development. Kotlin is 100% interoperable with Java and offers backward compatibility with Java and Android projects. Kotlin is an enterprise level language aimed at resolving real-world development problems.
