Cutting Costs in Mobile App Development Without Sacrificing Quality: The Role of Kotlin Multiplatform


In the evolving landscape of mobile app development, the quest for efficiency and quality has led developers to explore cross-platform solutions. Among these, Kotlin Multiplatform for Mobile (KMM) emerges as a compelling choice, offering a blend of native experience with the convenience of a shared codebase. This approach not only promises to streamline the development process but also to keep costs in check without compromising the end product’s quality.

Why Kotlin Multiplatform?

KMM distinguishes itself by enabling developers to write shared code for both iOS and Android platforms using Kotlin. This approach reduces the need for duplicate code, cutting down on development time and costs. By leveraging native languages and tooling for the UI and sharing business logic, KMM ensures that apps deliver a native user experience.

The Mechanics of KMM

Kotlin serves as a common language across platforms, with platform-specific libraries bridging any gaps. Android Studio and IntelliJ IDEA support KMM with plugins, simplifying project setup. The “expect” and “actual” declarations in KMM allow for seamless integration of platform-specific functionalities, ensuring that the shared codebase can adapt to the unique requirements of each platform.

Advantages of KMM in Reducing Costs

  • Single Codebase: By maintaining a single codebase for both platforms, KMM reduces the development and maintenance costs.
  • Code Consistency: Shared business logic enhances code consistency, making it easier to manage and update the app.
  • Native Performance: Despite the shared code, the app retains a native look and feel, ensuring high user satisfaction without extra costs.

Addressing Limitations

While KMM is a powerful tool, it’s important to acknowledge its limitations, such as the relative novelty of the technology and the current scarcity of third-party libraries. However, the ongoing growth of the KMM ecosystem and its robust documentation support mitigate these issues, making KMM a viable option for many developers.


Kotlin Multiplatform for Mobile represents a forward-thinking approach to mobile app development, striking a balance between cost-efficiency and quality. By reducing the need for duplicate code and leveraging the strengths of Kotlin, developers can deliver high-quality native apps faster and more economically. As the technology matures and its ecosystem expands, KMM is poised to become a key player in the cross-platform development space.

Next Steps

For developers interested in exploring KMM, diving into the official documentation and leveraging testing tools provided by KMM are excellent first steps. These resources offer insights into advanced features, interoperability with other languages, and custom Gradle tasks, ensuring developers are well-equipped to take full advantage of KMM’s potential in their projects.
