What is Kotlin?

Kotlin is a statically typed language that enables building web, cross-platform and Android apps, among others. Both well-known brands and start-ups use it. Uber, Pinterest, Evernote are just a few of many apps developed in Kotlin that have millions of users now.

The key to its popularity is simplicity. JetBrains team, Kotlin’s creators, made sure it is clear and intuitive, so the Android development becomes easier.

As a result, Kotlin is appreciated by software engineers who can spend less time on creating native components thanks to this language. Product owners and investors are no less interested in its benefits. It allows an enterprise to release products earlier and enjoy the profits sooner.

Recommended by Google

Kotlin is currently developed as an open-source project and offers software engineers more and more possibilities. Even Google saw its potential and chose it as
a preferred programming language for Android development
in 2019.

With this very platform in mind, we create native apps using Kotlin. Depending on user needs, we build apps from scratch or add new components. It’s possible even if the first creators of the app were using Java. Android Studio offers special tools that make it possible to covert  a code written with Java into a Kotlin code.

Why choose Kotlin?

Android apps efficiency stats

01 Better performance

Clear, intuitive code lets developers quickly add new elements to apps, whereas the access to extensive libraries of Java and Kotlin, and the official Android SDK makes the development easier. It also boosts the effectiveness of the entire process.

02 Shorter development time

The conciseness of Kotlin means less code needed to create a component. It also means less time required for the development of the app. The simple structure of this language optimizes the process of programming and speeds it up.


03 Cost savings and protection from errors

Build-in protection that detects null pointer exceptions, clear code, static code analysis tool, and large community – it all prevents software developers from making errors. This is also helpful because it lets companies save time and resources usually spend on fixing bugs.

04 Customization

Using native gestures and UI elements makes apps more intuitive. As a result, users can reach their goals faster which is more satisfactory and encourages them to discover new features.

05 More possibilities

Kotlin can easily access system components, so building features that are based on the elements of hardware, such as GPS, Bluetooth, or a camera, is more simple. This is especially important for every growth-driven business because in case of native apps there aren’t so many limitations concerning new components.

Kotlin vs Java

For many years Java was the main language for Android app development. But younger Kotlin took its place some time ago. What triggered this change? Conciseness is one of the main reasons.

Kotlin has clear syntax and it usually takes fewer lines of code to build a component, compared to Java. What’s more, Kotlin allows us to use function operators and provides many helpful features. Sometimes there’s even no need to use the libraries.

It all shortens the time required to develop an app. So, if you want to add new components, keep in mind that Kotlin lets you achieve the same effects as Java, only faster.
