Kotlin vs React Native


Do you know that, on average, people spend 80% of their mobile time on apps? This highlights that the mobile app industry is enormously waving its presence. Moreover, recent average stats show that app usage and smartphone penetration is growing briskly at a steady rate.

Now that we’re talking about developing mobile apps, let’s look at an example. We all know building requires a plot of land, and similarly, building a mobile application necessitates an app development platform. In the current tech landscape, there are many app development platforms hitting the market, each vying to be the best among others. Currently, there are two major contenders dominating the market race, i.e., React Native and Kotlin, the two leading cross-platform development tools are used by developers to create robust mobile applications. In this blog, let’s delve into comprehensive information to determine which platform reigns superior in the realm of app development.

What is React Native?

What is React Native

React Native is a Javascript framework developed by Meta, used to create intuitive native applications for Android and iOS. React Native consists of rich mobile UI components. Its working principle does not manipulate DOM and runs in the background process. It offers both better UIs and UXs, which is why it is the most adored by developers.

Features of React Native

  • Open source
  • Improvements & upgrades are frequent as it is backed by Facebook
  • Modular and intuitive architecture boosts flexibility to make updates
  • Speeds up the development process by taking less time to load
  • Large developer community
  • Saves a significant amount of time and cuts the cost to half
  • Inbuilt with a fascinating additional feature popularly known as a live-to-reload feature (empowers you to check the aftereffect)

Use cases of React Native

  • Bloomberg app implements automated code refreshes, this aids the users to get the latest updates once opening the app.
  • Facebook Ads Manager is a space to manage advertisements of products and is built entirely on React Native. It is cross-platform, and it handles UI differences. Its UI’s animations and transitions meet the same standard.
  • Instagram integrated React Native to overcome prevailing tech challenges. It enables faster push features and maintains iOS and Android app versions.

What is Kotlin?

What is Kotlin

Kotlin is a cross-platform developed, designed, and supported by JetBrains. It is a programming language with a type interface. It interoperates fully with Java and the JVM version. Google announced it as a preferred programming language for Android app developers.

Features of Kotlin

  • Clean and concise code
  • Facilitates null safety as most of the app crashes are due to a null pointer
  • Being an expressive code, it is easily understandable by every programmer
  • Modular features increase productivity
  • 100% interoperability with Java
  • User can transcompile Kotlin code to JavaScript code

Use cases of Kotlin

  • Evernote integrated Kotlin to bolster the app’s existing capabilities. It comes with additional features for users like scanning, photos, audio, to-do lists, and more.
  • Swiggy – 74% of the app is written in Kotlin programming language. Soon after migrating all-new feature development to Kotlin, the company witnessed a 50% reduction in app crashes.
  • Netflix is currently using KMM. The application handles multiple configurations through an internal management tool called Hendrix.

What Are The Pros And Cons of React Native?

Advantages of React Native

1. Accelerated development: Cross-platform apps reduce the time required for the development process. These are ready-to-use components that expedite the development process.

2. Learning curve: Devs with React experience are able to develop RN apps without difficulty, as ideas and modules are both in systems overlap.

3. Quick Fixes (OTA updates): OTA updates enable swift fixes and improvements to be deployed. The updates are reviewed by the digital distribution service before the launch.

4. Fast Refresh: React Native allows a developer to make changes in the codebase without the need of reloading the entire application. This improves their overall efficiency, leading to faster iteration cycles.

5. Cohesive team collaboration: React Native fosters seamless collaboration with the capability to allow one team to work on multiple codes, reducing the need for multiple teams.

6. Exceptional performance: Developers can examine JavaScript code to gain similar performance results in React Native and Swift.

7. Simplified UI: React Native utilizes declarative programming to develop mobile UI, which facilitates effortless spotting of bugs or errors.

8. Large community: React Native is an open-source platform, bolstered by a vibrant community of developers allowing them to share valuable insights and support.

Disadvantages of React Native

1. Compatibility and debugging: React Native is still in beta, so developers may encounter issues with package compatibility and debugging tools.

2. Upgrading issues: Upgrade helpers and community guides are available to support users during the transition between React Native versions.

3. Lack of custom modules: React Native lacks certain components and may require multiple codebases, resulting in differences in behavior and appearance on different platforms.

4. Native code still needed: Native programming skills are necessary for some features of React Native, but open-source libraries may not be enough.

5. Extra focus on performance: Developers should focus on performance and avoid unnecessary rerendering to improve app performance.

What Are The Pros And Cons Of Kotlin?

Advantages of Kotlin

1. Less code: Kotlin provides less code with high readability, resulting in fewer bugs and better chat apps.

2. Developer Friendly: Kotlin has solved the challenges of building a real-time chat app using IntelliJ IDEA, such as null pointer exceptions.

3. Compatibility with Java: Kotlin is highly compatible with Java regarding chat app solutions but does not support bytecodes older than 1.8.

4. Easy to adopt: Engineers can use Kotlin to streamline Android chat app development.

5. Multiplatform supporting: Kotlin supports JavaScript and interoperability, enabling cross-platform development.

6. Strong community: JetBrains improved Kotlin to create a stable business model and the flagship of a large community.

Disadvantages of Kotlin

1. Limited learning sources: Kotlin is becoming increasingly popular, but a limited developer community is available.

2. Compilation speed: Kotlin is faster than Java, but still incomparable for clean building.

3. Different from Java: Kotlin and Java differ in many aspects, making it difficult to switch.

Moreover, it is a popular platform for creating robust yet efficient applications.

We know that navigating through these choices can be a tough call, but fear not, our team of experts will surely help you to make an informed decision.



1. Which is better: React Native or Kotlin?

There is no doubt that React Native works wonders when it comes to building cross-platform applications. Whereas, Kotlin is taking advantage of being the best choice for app development for the developer who has no knowledge about developing cross-platform applications.

2. Is React Native similar to Kotlin?

No, React Native is an open-source UI framework, whereas Kotlin is a programming language. But they both are used in multi-platform app development.

3. Which one is best for Android development?

Kotlin multi-platform enables developers to share logic and libraries below the UI layer, allowing them to interact with their native environment. Unlike Kotlin, React Native does not demand developers to follow its own UI.

4. Does React Native has faster speed?

React Native is connected with the plugin through the framework, allowing the platform to run smoother and load faster.
