Getting Started

Why Kotlin?

Uber, Trello, Evernote, and others use Kotlin to provide their users with a superior Android app experience and keep their business growing.

  • Faster development

    On average, building Kotlin apps takes notably less time compared to other native programming languages. This is because Kotlin comes with a dozen of in-built features that - when used properly - can speed up the development process.

    So, if you need to quickly build a full-featured mobile app for Android with heavy hardware utilization, Kotlin is definitely your choice.

  • Better security

    Kotlin is more secure than its predecessor (Java). This means you can save time and budget for marketing your application instead of spending resources on doublechecking whether your app is secure enough for market release.

    Being security-focused by default also makes Kotlin apps more simple from the inside and, thus, less vulnerable to unexpected crashes.

  • Enables business agility

    Kotlin programming language is completely backward-compatible with Java. Put simply, if you have a Java application, you can reuse its code to build a new app in Kotlin without having to rewrite the entire thing from scratch.

    Not only is this cost-efficient for both small and large projects, but also enables faster market releases.

  • Easier to maintain

    Kotlin is extremely concise and easy to understand. As a result, developers are less busy with heads or tails of long code and focus on improving features that are essential to your business.

    Speaking facts, Kotlin is by 40% more concise as compared to Java, which is a lot even by modern standards.

Real Projects. Real Numbers.
