Compose Navigation in KMP: Patterns That Scale

Navigation in Compose Multiplatform is evolving fast. After trying Voyager, Decompose, and the official Compose Navigation, here are the patterns we settled on at MBS for our production apps. The Navigation Challenge in KMP Unlike single-platform apps, KMP navigation must work across Android (with its back stack), iOS (with swipe-to-go-back), and Desktop (with window management). The solution must handle deep links, state restoration, and type-safe argument passing — all in s

Building Offline-First Apps with KMP

Users expect apps to work without internet. At MBS, every product we build is offline-first by default. Here are the architecture patterns and implementation strategies we use in Kotlin Multiplatform. The Offline-First Architecture Our pattern is simple: local database is the single source of truth. UI reads from local storage (SQLDelight). Network requests update local storage. The UI reactively updates via Kotlin Flows. This means the app works instantly on launch, even wit

Koin vs Dagger in KMP: A Practical Comparison

Dependency injection is critical for maintainable KMP apps. We've used both Koin and Dagger/Hilt extensively in production. Here's when to choose each, with real examples from our apps. Koin: The KMP-First Choice Koin is multiplatform from the ground up. No annotation processing, no code generation, no platform-specific setup. Define modules in shared code and they work everywhere. The DSL is intuitive, testing is straightforward with checkModules(), and the learning curve is

The State of Kotlin Multiplatform in 2026: A Production Perspective

After 4 years of shipping KMP apps to production, here's our honest assessment of what works, what doesn't, and where the ecosystem is heading. Mobile Byte Sensei has built 6 products with KMP — this is what we've learned. What Works Brilliantly Shared business logic is KMP's killer feature. Networking (Ktor), serialization (kotlinx.serialization), DI (Koin), and local storage (SQLDelight) all work flawlessly across platforms. Compose Multiplatform for shared UI has reached p

SQLDelight Migration Guide: Room to Multiplatform

Migrating from Room to SQLDelight is one of the most common steps when adopting Kotlin Multiplatform. At MBS, we've migrated three production apps. Here's the step-by-step guide we wish we had when we started. Why SQLDelight? Room is Android-only. SQLDelight generates Kotlin code from SQL statements and works across Android, iOS, Desktop, and Web. It gives you type-safe queries, automatic schema migrations, and coroutine/flow support — all shared across platforms. Step 1: Map

Why We Chose KMP Over Flutter for Mood Movies

When we started building Mood Movies at Mobile Byte Sensei, we evaluated every major cross-platform framework. Flutter, React Native, and Kotlin Multiplatform were all strong contenders. We chose KMP — and after 2 years of production experience, we'd make the same choice again. Here's why. The Decision Framework Our criteria were: native performance on all platforms, ability to share business logic without compromising UX, access to the full Kotlin ecosystem, and a migration

Getting Started with Compose Multiplatform in 2026

Compose Multiplatform has matured significantly in 2026, making it the go-to choice for shared UI across Android, iOS, Desktop, and Web. At Mobile Byte Sensei, we've been building production apps with Compose MP since its early days. Here's your complete guide to getting started. Why Compose Multiplatform? Traditional cross-platform frameworks force compromises. Flutter uses its own rendering engine. React Native bridges to native views. Compose Multiplatform takes a differen

Building a Production-Ready KMP App: Lessons from Mood Movies

Mood Movies is our flagship KMP app — a cross-platform movie discovery experience that matches recommendations to your current mood. Building it taught us invaluable lessons about shipping production-quality KMP apps. Here's what we learned. Architecture That Scales We adopted a clean architecture with shared domain and data layers, platform-specific UI where needed, and Koin for dependency injection across all targets. The key was designing the module structure early — share

Why We Chose Compose Multiplatform for Our Products

When we started building products at Mobile Byte Sensei, we faced a critical decision: how to handle UI across platforms. After evaluating Flutter, React Native, and native development, we chose Compose Multiplatform. Here's why. The Problem with Cross-Platform UI Traditional cross-platform frameworks force you into a single rendering engine that approximates native look and feel. This works for simple apps but breaks down when you need platform-specific behaviors, animations

Getting Started with Kotlin Multiplatform in 2026

Kotlin Multiplatform (KMP) has evolved from an experimental feature to a production-ready framework that powers apps across Android, iOS, desktop, and web. At Mobile Byte Sensei, we've been building with KMP since its early days, and 2026 is the best time to start your KMP journey. Why KMP in 2026? The KMP ecosystem has matured significantly. Compose Multiplatform now supports Android, iOS, desktop, and web with a single UI codebase. Libraries like Ktor, Koin, and SQLDelight
