Kotlin Multiplatform App Development
Share business logic between Android and iOS with Kotlin Multiplatform (KMP) — one tested core for data, networking and rules, with native or shared UI on each platform, connected to your back end or Odoo.
For businesses that need Android and iOS apps without two separate codebases, teams with an existing Android app to bring to iPhone, and companies that want consistent business rules on every platform.
What we deliver
- Architecture for shared and platform code
- Shared business logic and data layer
- Native or shared UI per platform
- APIs and Odoo / ERP integration
- Testing on Android and iOS
- Store releases and ongoing support
Trusted by businesses in retail, textile, distribution, services and the public sector
Why Teams Choose Kotlin Multiplatform
Building the same app twice creates cost, drift and delay. These are the problems KMP helps solve.
The same logic written twice
Android and iOS teams re-implement identical rules.
Platforms drift apart
Prices, validations or calculations differ between apps.
Features ship at different times
One platform always waits for the other.
An Android app with no iOS version
Rebuilding for iPhone looks like starting over.
Cross-platform apps that don’t feel native
Some frameworks compromise the platform experience.
Integration code duplicated
API and sync logic is maintained in two places.

Share Logic, Keep the Native Experience
With Kotlin Multiplatform, the parts of your app that should behave the same everywhere are written once. The parts users see and touch can stay fully native, so each app still feels right on its platform.
- Shared data models and business rules
- Shared networking and API client
- Shared local storage and sync
- Native Android and iOS interfaces
- Platform features accessed natively
What Can Be Shared With Kotlin Multiplatform?
A typical split. We agree the exact boundaries during architecture design.

Kotlin Multiplatform vs Other Options
We recommend the approach that fits your app, team and roadmap.
Two native apps
Hybrid apps
- Single codebase and UI
- Fast to reach both stores
- Some platform trade-offs
- See hybrid apps
Kotlin Multiplatform
- Shared logic, native feel
- Consistent rules on both platforms
- Gradual adoption possible
- Strong fit for existing Kotlin apps

Why Choose MP Technolabs for Kotlin Multiplatform?
Mobile developers who know both platforms and the business systems behind them.
How Much Does Kotlin Multiplatform Development Cost?
We estimate after understanding your scope. The main factors are:
| Factor | Why it matters |
|---|---|
| Features & screens | Size of the build |
| Shared vs native UI | Amount of platform-specific work |
| Existing code | New app or extending an Android app |
| Back end | New APIs or existing systems |
| Integrations | Odoo, ERP, payments, maps |
| Offline needs | Local storage and sync |
| Support | Updates after launch |
How Long Does It Take?
The timeline depends on scope. The main drivers are:
- Number of features and screens
- How much UI is shared
- Existing Android code to reuse
- Back-end and integration work
- Testing and store review on two platforms
We often launch a focused first version and add features in later releases.

Kotlin Multiplatform FAQs
What businesses ask before choosing Kotlin Multiplatform.
What is Kotlin Multiplatform used for?
It is used to share code such as business logic, networking and data handling between Android and iOS apps, while keeping native platform code where it is needed.
Does Kotlin Multiplatform share the user interface too?
It can. You can keep fully native UI on each platform, or share UI with Compose Multiplatform where it fits. We decide per project and per screen.
Will a KMP app feel native on iPhone?
Yes, if the UI is built natively with SwiftUI or carefully with shared UI. Because only the chosen layers are shared, the iOS app can follow Apple’s design conventions.
How is KMP different from hybrid frameworks?
Hybrid frameworks usually share one codebase including the UI. KMP shares Kotlin code selectively and keeps native platform code, which gives more control over the platform experience.
Can we add iOS to our existing Android app with KMP?
Often yes. Existing Kotlin business logic can be moved into shared modules step by step, and the iOS app built on top. We assess the codebase first.
Do we have to share everything from day one?
No. KMP can be adopted gradually, starting with one module such as networking or data, and extended over time.
Can a KMP app integrate with Odoo?
Yes. We build a shared API client that connects to Odoo, so both Android and iOS apps read and update the same data.
Can the app work offline?
Yes. Shared local storage and sync logic can keep key data available offline and synchronise when a connection returns.
Do you publish to Google Play and the App Store?
Yes. We prepare both releases and work with you through store review. Apps are published under your developer accounts.
How do you test KMP apps?
Shared code is covered by one set of tests, and each app is tested on real Android and iOS devices before release.
Do you provide maintenance after launch?
Yes. We keep Kotlin, libraries and both platforms up to date and add new features.
Will you sign an NDA?
Yes. We keep project information confidential and can sign an NDA before discussing your app in detail.
How is the app’s source code licensed?
The code we develop is licensed to you for use in your business. Licence terms are set out in the contract before development starts.
How long does Kotlin Multiplatform development take?
It depends on features, shared vs native UI, existing code and integrations. You receive a timeline after the discovery phase.
How much does Kotlin Multiplatform development cost?
It depends on features, UI approach, existing code, back end, integrations, offline needs and support. Request an app estimate.
