Kotlin Multiplatform (KMP) is an open source technology developed by JetBrains that enables flexible cross-platform application development. With this tool, KMP app developers can reuse a single Kotlin codebase across Android, iOS, web, desktop, and server-side applications while retaining the benefits of native programming. This approach ensures high performance and full access to platform-specific SDKs, enabling developers to build applications for different operating systems such as iOS, Android, and others, while retaining native code when necessary for optimal results.
Kotlin Multiplatform (KMP) is not a typical cross-platform technology like Flutter or React Native. Instead, it’s a versatile set of tools that enables developers to write code in Kotlin, a language that is inherently designed for multiplatform use.
Unlike other cross-platform frameworks, KMP doesn’t rely on its own engine or virtual environment. Instead, it compiles Kotlin code into other languages using specialized compilers:
This way, Kotlin Multiplatform can seamlessly integrate with native environments across platforms.
Kotlin Multiplatform is ideal if you:
Cross-platform frameworks like Flutter and React Native often introduce new languages, frameworks, and ecosystems. In contrast, Kotlin Multiplatform (KMP) simplifies the process by enabling developers to continue using the familiar Kotlin language.
Also, Flutter uses its own UI rendering engine, which means it draws everything on the screen itself. This ensures a consistent look and feel across devices, regardless of platform, but it doesn’t use the native UI components of Android or iOS. Kotlin Multiplatform, on the other hand, uses each platform’s native tools, such as Jetpack Compose on Android and SwiftUI on iOS, to build the visual parts of the app. This approach ensures that the app made with KMP adheres to native guidelines, provides a platform-specific look and feel, and is more scalable.
In essence, Kotlin Multiplatform extends native applications by enabling code sharing, while Flutter replaces the native framework with its own. Both KMP and Flutter deliver native performance, but they take different approaches to achieving cross-platform compatibility.
The cost of developing an app using Kotlin Multiplatform (KMP) can vary significantly depending on the complexity and scope of the project. Every app is unique, so factors such as features, design, and integrations will affect the final cost. However, we can provide a general estimate based on the type of app:
Please note that these estimates do not include backend development costs, which will vary depending on the needs of your project. For a more accurate estimate, don’t hesitate to contact us.
Yes, KMP is ideal for both Android and iOS development. It enables Kotlin Multiplatform app developers to write common business logic in Kotlin that can be reused across both Android and iOS platforms, reducing duplication of effort.
Kotlin also offers two-way interoperability with native languages, like Java or Objective-C, so developers can still take advantage of platform-specific features and performance optimizations for each operating system (Android and iOS) while maintaining a common codebase for shared components. This makes KMP one of the top solutions for cross-platform application development.
Kotlin Multiplatform app developers can efficiently reuse code across a wide range of platforms, including iOS, Android, macOS, Windows, Linux, web, and server-side environments, while retaining the benefits of native programming.
Thanks to its interoperability with Java, Kotlin works seamlessly on Android and can also be used in desktop and server applications. With support for JavaScript, Kotlin can power both the frontend and backend of web applications. Finally, its compatibility with C and Objective-C enables rapid development for both Linux-based systems and Apple operating systems such as iOS, macOS, watchOS, and tvOS.
Kotlin Multiplatform (KMP) is a set of tools that enables developers to write code in Kotlin, which is then translated by specialized compilers into native code for the target platforms.
These compilers include:
In this way, Kotlin Multiplatform app development companies can streamline the app development process.
Also, the translation from Kotlin to native code occurs only once before the app is deployed, ensuring that the final product is fully native, similar to apps built without KMP. This enables efficient cross-platform development while maintaining high performance and platform-specific core functionality throughout.
Kotlin Multiplatform (KMP) offers several application development advantages that make it a strong choice for building cross-platform applications:
Kotlin Multiplatform (KMP) differs from other cross-platform solutions like Flutter and React Native in that it enhances native application development, not replaces it. While Flutter and React Native introduce new languages, frameworks, and entire ecosystems, KMP keeps things simple by helping developers to continue using the familiar Kotlin language.
KMP focuses on sharing core logic across platforms, with Kotlin compilers translating that shared code into platform-specific code for Android, iOS, Web, and more. The shared code is then used within native applications, ensuring that developers can maintain the native performance and UI without having to adopt an entirely new development framework or language.
You should choose Kotlin Multiplatform (KMP) when you want the benefits of both native and cross-platform development. Here’s when KMP is the right choice:
The cost of developing an app using Kotlin Multiplatform (KMP) can vary depending on the specifics of the project, such as complexity, features, and design requirements. However, in general, developing a mobile app using a KMP is often about 30% less expensive than building two separate native apps for Android and iOS.
This cost reduction is primarily due to KMP’s ability to share core logic across platforms, reducing duplication of effort while still delivering a native experience on each platform. While every project is different, KMP’s efficiency enabling code sharing typically results in lower development costs and faster timelines compared to traditional native app development.
If you want to reduce development time and costs, consider cross-platform solutions such as Flutter, React Native, or Kotlin Multiplatform (KMP). These technologies allow you to build applications for multiple platforms using a common codebase, significantly reducing development time, effort, and cost.
In particular, KMP supports the sharing of core logic across platforms while maintaining native UI and performance. By leveraging the power of the Kotlin language, KMP can accelerate development by up to 30%, allowing you to deliver features faster and reduce the overall cost of maintaining and building your application. It’s an ideal solution for organizations looking to streamline their development efforts without compromising the native experience.
Converting a native application to Kotlin Multiplatform (KMP) is much easier than starting from scratch with other cross-platform solutions. With KMP, you don’t need to rewrite your entire app. Instead, you can migrate incrementally by moving more Android code into a shared module that can also be integrated into your iOS app. This approach enables you to maintain the quality and functionality of your app while realizing the benefits of cross-platform development much sooner.
KMP is also flexible, meaning it can be integrated at any stage of your app’s lifecycle – whether you’re starting a new project, working on an MVP, or have a mature product. This is a huge advantage over traditional solutions, where you often have to choose between a fully native or cross-platform application.
To choose the best Kotlin Multiplatform app development company for your project, start by evaluating their portfolio to ensure they have strong experience in providing Kotlin Multiplatform app development services. Look for projects that demonstrate their expertise in KMP and see if they have successfully implemented solutions similar to what you need.
Next, check reviews on platforms like Clutch to get an idea of their reputation. Focus on KMP app development companies with positive client feedback, especially in the context of Kotlin Multiplatform development and app developers, as well as their ability to meet client needs.
Once you’ve narrowed down a few companies, reach out to them and have direct conversations. This will help you determine if their KMP app developers understand your vision and match your expectations. Communication and compatibility are essential, so finding a company that is a good match for your project and working style is crucial for a successful collaboration.
