Why Your Competitors Are Shipping 2x Faster
They're building once, deploying everywhere. You're still maintaining separate codebases.
Kotlin Multiplatform lets you write your business logic once and deploy it to Android, iOS, Desktop, and Web - all from a single codebase. While you're fixing the same bug three times, they've already shipped their next feature.
We Build Your Cross-Platform Apps
At Prospat, we develop high-performance Android, iOS, Desktop, and Web applications using Kotlin Multiplatform. We help businesses launch faster and reduce costs by writing code once and deploying everywhere.
✓ Expert Development
We deliver production-ready apps with shared business logic and platform-specific UI
✓ Faster Time to Market
We help you launch on all platforms simultaneously without maintaining separate codebases
✓ Lower Development Costs
We reduce your development and maintenance costs by up to 60% with code sharing
Technical Benefits & Features
Maximum Code Reuse
Share business logic, networking, data persistence, and algorithms across platforms. Typically achieve 60-90% code sharing depending on project requirements.
Native Performance
Compiles to native code on each platform. No overhead from interpreters or virtual machines - your code runs at full native speed.
Platform-Specific APIs
Use expect/actual declarations to access platform-specific features while maintaining shared code. Full access to iOS, Android, and platform-specific capabilities.
Interoperability
Seamlessly integrate with existing Swift/Objective-C (iOS) and Java/Kotlin (Android) codebases. Adopt gradually without full rewrites.
Type Safety
Kotlin's strong type system catches errors at compile time, reducing runtime crashes and improving code quality across all platforms.
Modern Tooling
Full IDE support in Android Studio and IntelliJ IDEA with debugging, refactoring, and code completion across platforms.
Use Cases & Examples
Mobile Applications
Build iOS and Android apps sharing business logic, API clients, data models, and validation while using native UI frameworks (SwiftUI/Jetpack Compose or Compose Multiplatform for fully shared UI).
Cross-Platform Desktop Apps
Create desktop applications for Windows, macOS, and Linux using Compose Multiplatform, sharing code with your mobile applications.
Backend & Frontend Sharing
Share data models, validation logic, and business rules between Kotlin backend services (Ktor, Spring) and multiplatform clients.
SDK Development
Create libraries and SDKs that work across multiple platforms from a single codebase - perfect for analytics, networking, or utility libraries.
