Kotlin Everywhere. One Team.
We partner with you to build cross-platform applications with Kotlin Multiplatform and Compose Multiplatform—sharing business logic and UI across iOS, Android, web, and desktop. If your team already knows Kotlin and Jetpack Compose, CMP is the shortest path to cross-platform without starting over. Our deep native expertise on both iOS and Android means we handle the platform-specific integrations that pure Kotlin teams struggle with.
Why Compose Multiplatform Is a Strategic Advantage
For teams already invested in Kotlin and Jetpack Compose, Compose Multiplatform is the most natural path to cross-platform development. You keep your existing skills, architecture patterns, and much of your codebase—and extend it to iOS, web, and desktop.
Leverage Your Kotlin Investment
If your team already builds Android with Kotlin and Jetpack Compose, CMP means they can build for iOS and other platforms without learning a new language or framework. Same Compose UI model, same coroutines, same architecture patterns—applied everywhere.
Incremental Adoption
Unlike Flutter or React Native, KMP does not require a rewrite. Start by moving shared business logic (networking, data models, validation) into a multiplatform module. Add shared UI with Compose Multiplatform when you are ready. Adopt at your own pace without disrupting your existing apps.
Native Where It Matters
KMP's expect/actual mechanism lets you share code where it makes sense and drop into native platform code where it does not. Need UIKit for a specific iOS screen? Need a platform-specific sensor API? CMP makes that natural, not a workaround.
One Language, Full Stack
Kotlin runs on the JVM, compiles to native iOS code, transpiles to JavaScript, and runs on the server with Ktor. A single language across your mobile apps, web frontend, and backend means fewer context switches, simpler hiring, and more code sharing.
Backed by JetBrains and Google
Kotlin is developed by JetBrains and officially supported by Google for Android. Compose Multiplatform builds on Jetpack Compose—Google's modern UI toolkit. You are building on a technology stack with strong institutional backing and a growing ecosystem.
Proven at Scale
KMP is used in production by Netflix, Cash App, Philips, VMware, and others. Compose Multiplatform for iOS reached stable in 2024. The technology is production-ready, and the ecosystem is maturing rapidly with Navigation 3, shared resources, and platform-specific integration APIs.
What We Deliver
Our team brings deep Kotlin and Jetpack Compose expertise to every CMP project. We have been building with Kotlin Multiplatform since its early days, and as native iOS and Android experts, we handle platform-specific integrations that pure Kotlin teams cannot.
KMP and CMP: Understanding the Layers
Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP) are related but distinct. Understanding the difference helps you decide how much to share across platforms.
Kotlin Multiplatform (KMP) — Shared Logic
KMP lets you share business logic in Kotlin across platforms—networking, data models, validation, state management. Your iOS app uses the shared Kotlin code compiled to native, while keeping a SwiftUI or UIKit interface. This is the safest starting point: high code sharing, zero UI risk.
Compose Multiplatform (CMP) — Shared UI
CMP extends KMP by sharing the UI layer too—using Jetpack Compose to render on iOS, desktop, and web. If your team already builds Android UI with Compose, CMP means that same UI code runs on iOS. The tradeoff is less platform-specific UI polish, which matters more for some apps than others.
Incremental Path
Most teams start with KMP (shared logic only), then evaluate CMP for new screens or features. This lets you validate the approach with low risk before committing to shared UI. We help you decide where the line should be for your specific product and team.
Platform-Specific When Needed
KMP's expect/actual mechanism makes it natural to drop into Swift on iOS or Kotlin on Android for platform-specific features. Unlike some cross-platform frameworks, you are never fighting the system to access native capabilities. We build the native integrations that make your shared code work seamlessly on each platform.
Growing Ecosystem
The KMP/CMP ecosystem is maturing fast. Navigation 3 brings modern navigation patterns, shared resources handle images and strings across platforms, and libraries like Ktor, SQLDelight, and Koin provide multiplatform-ready infrastructure. JetBrains and Google are actively investing in making KMP a first-class development experience.
Server-Side Kotlin Too
KMP does not stop at mobile. Shared Kotlin modules can also be consumed by Ktor backend services—meaning your data models, validation logic, and business rules stay consistent across mobile apps, web, and server. One language, one source of truth, from client to server.
Why Native Expertise Makes Our CMP Work Better
Many teams exploring CMP come from an Android background and struggle with the iOS side. We bring expert-level knowledge of both platforms—which is exactly what CMP projects need.
iOS Integration Depth
When your CMP app needs HealthKit, Core Location, or UIKit interop, you need someone who knows iOS at the native level. We build the Swift-side integrations that make your Kotlin Multiplatform code work correctly on Apple platforms—handling the edge cases that documentation does not cover.
Android Platform Expertise
Our Android team has been building with Kotlin since it was announced for Android, and with Jetpack Compose since its alpha. We bring deep understanding of Android architecture components, lifecycle management, and the Compose rendering model that CMP builds on.
Navigation and Architecture
We wrote about Navigation 3 for Compose Multiplatform and have practical experience with the architectural decisions that make or break CMP projects—state management patterns, navigation strategies, and how to structure expect/actual declarations for maintainability.
Honest Framework Guidance
We build with Flutter, React Native, native iOS, native Android, and CMP. We recommend CMP when it genuinely fits your situation—not because it is the only tool we know. If another approach would serve you better, we will tell you.
Build Tooling and CI/CD
KMP projects have unique build complexity—Gradle configuration, Kotlin/Native compilation, CocoaPods or SPM integration for iOS. We set up CI/CD pipelines that build, test, and deploy your multiplatform project reliably, so your team is not fighting tooling issues instead of shipping features.
Testing Across Platforms
We write shared tests in common Kotlin code that run on every target platform, supplemented by platform-specific tests where behavior differs. Our testing strategy catches cross-platform issues early—before they reach your users on iOS or Android.

Using an AI Agent to Upgrade from Navigation 2 to Navigation 3 in Android
Free Gemini vs. paid Claude Code on a real Android migration task. Both agents produced working code, but the experience was dramatically different. Here's what I learned comparing them.
Navigation 3 for Compose Multiplatform: Should You Migrate?
Nav 2's imperative calls never felt right in Compose. Nav 3 treats navigation as state — and it changes everything. Here's when to migrate and when to wait.
Compose Multiplatform: A Practically-Native Example, Part 2
Building on Part 1, we add markers, camera controls, and touch interactivity to our cross-platform Google Maps Composable. Here's how it all comes together.
How We Added Google Maps to a Compose Multiplatform App (Android + iOS)
No CMP Composable for maps? No problem. We used expect/actual, UIKitView, and Koin DI to wrap native Google Maps on both platforms. Full code walkthrough.
