I will develop ios and android mobile app
Haris W
About this gig
Looking for a premium mobile app for both iOS and Android without paying for separate native development?
I specialize in app development using Compose Multiplatform (CMP), creating high-performance mobile applications with shared codebase while maintaining a truly native user experience on both platforms. This approach reduces development costs, accelerates delivery, and simplifies long-term maintenance.
Whether you need a business app, SaaS platform, marketplace, social networking app, or AI-powered solution, I can design and develop a scalable product tailored to your goals.
Unlike traditional cross-platform frameworks such as Flutter and React Native, Compose Multiplatform enables deeper native integration, excellent performance, and a modern development experience with shared codebase.
What You'll Get
Modern Shared UI Architecture
- Beautiful, Shared responsive UI built with Compose Multiplatform (Kotlin)
- Native performance on both iOS and Android
- Consistent user experience across platforms
- Faster development and feature delivery
Please message me with your project details before ordering so we can map out your app's custom architecture!

FAQ
What is the benefit of Compose Multiplatform over Flutter and React Native?
Unlike React Native's slow JavaScript bridge or Flutter's non-native canvas, Compose Multiplatform compiles to native machine code. It uses Jetpack Compose for UI, letting you share up to 95% of code while retaining 100% native performance and direct access to iOS/Android platform APIs.
Which backend option is best for a Compose Multiplatform app?
For rapid MVP launches, serverless backends like Firebase or Supabase are best. For complex data engineering, strict compliance, or high concurrency, we build custom backend architectures using Golang, Node.js, or Python.
Will the Shared UI feel laggy or slower than a fully native app?
Not at all. Unlike hybrid engines with slow JavaScript bridges, Compose Multiplatform compiles to native machine code on iOS and Android. The UI draws natively, maintaining fluid 60fps/120fps animations and smooth scroll behaviors.
How do you handle navigation and state across Android and iOS?
We use production-grade KMP libraries: Koin for dependency injection, Ktor for networking, and Voyager or Nav2 or Nav3 for screen routing. App state is driven by reactive Kotlin Coroutines and StateFlow to guarantee synchronous UI updates.
What happens when iOS or Android receives a major operating system update?
We also offer ongoing maintenance retainers to handle annual OS-level updates, SDK changes, and third-party library upgrades so your app never breaks.
What is the benefit of Compose Multiplatform Shared UI over traditional KMP?
Traditional KMP only shares business logic. Stable Compose Multiplatform (CMP) shares up to 95% of code, including the entire UI and animations. You write screen designs once in Kotlin, maintaining a 100% consistent design system across Android and iOS.
