FAQ
How is Kotlin Multiplatform (KMM) different from Flutter or React Native?
KMM shares business logic (networking, data, use cases) across Android and iOS while the UI stays 100% native — Jetpack Compose on Android, SwiftUI on iOS. There's no custom rendering engine, so your app looks, feels and performs exactly like a native app, because it is one.
Do I need to hire separate Android and iOS developers?
No — that's the point of KMM. I build the shared core once and implement native UI on both platforms, so you get one point of contact instead of coordinating two separate teams.
Can you add KMM to my existing native Android or iOS app?
Yes. KMM can be integrated incrementally into an existing app rather than requiring a full rewrite. Send me your current codebase and I'll assess the scope.
What do you need from me to get started?
A short description of your app idea or existing project, any design/wireframes if available, and your target platforms — Android, iOS, or both.
Do I receive the full source code?
Yes — full source code and ownership is included in every package.
Can you help publish the app to the App Store and Play Store?
Yes, store submission support is included in the Premium package, and available as an add-on on Basic/Standard.
How long does a full MVP take?
Typically 2–4 weeks depending on scope and complexity — see the package delivery times above for specifics.
