Why Kotlin for
App Development

Interoperability with Java

Kotlin is interoperable with Java, which means that developers can use Java code and libraries in their Kotlin apps. This feature allows for the seamless integration of Java and Kotlin code, resulting in enhanced functionality and improved app performance. Kotlin's ability to interact with Java code also means that developers can leverage existing Java code and libraries, saving time and resources while improving application functionality.

Server-side app development

Kotlin can be utilized to develop a robust and reliable server-side app in a more expressive and concise way. Our Kotlin developers leverage this technology to its full potential and have the expertise to transpile Kotlin code to Javascript and build great server-side apps. They can create graphical and DOM elements and work with server-side technologies to deliver the desired outcomes.

Support For Coroutines

Coroutines are new function types that offer a flexible way to execute and stop functions as needed. Kotlin's support for coroutines allows developers to interrupt heavy workloads and restart them without losing any progress, resulting in a more streamlined development process. This can lead to significant time savings, enhanced speed and smooth user interface. With our kotlin app development services, you can get your app sooner than you realize.

Better Code Management

Kotlin is one such language that has gained widespread popularity due to its simplified syntax, making it easy to read and manage code. Its syntax is straightforward and intuitive, making learning more effortless. Kotlin also has advanced security features that make the codebase safe and protect it from potential issues. These features include null-safety checks, type inference, and secure type casting, among others, protecting against common vulnerabilities.

Object-oriented & Functional Programming

Kotlin allows developers to write code in object-oriented and functional programming styles. With Kotlin's support for object-oriented programming, developers can create classes, objects, and interfaces, making building complex systems easier. Its functional programming capabilities enable the writing of high-level functions that can be treated as variables and passed as parameters to other functions. This approach allows developers to write concise code that is easier to test and maintain.
