Native quality with shared logic

We build apps in Kotlin: native on Android, with business logic shared with iOS through Kotlin Multiplatform.

WHO IT IS FOR
Early stage

Native from the start

You want a native Android app with room to add iOS later without writing all the business logic a second time.

Growth stage

Legacy Java slows the team

The Android app is written in Java, new features take longer, and hiring developers for old code keeps getting harder.

Scale stage

Logic duplicated twice

iOS and Android implement the same business rules separately, and bugs appear on one platform but not the other.

WHAT IS INCLUDED
Code and architecture review with a development or migration plan
Native Android development in Kotlin and Jetpack Compose
Gradual migration from Java to Kotlin without pausing releases
Business logic shared between iOS and Android via Kotlin Multiplatform
Native interfaces on each platform: Compose on Android, SwiftUI on iOS
Tests on shared logic and CI/CD for both platforms
Google Play and App Store releases

Frequently asked questions

and answers

How is Kotlin App different from Android development?+

Android development is about your product on the Android platform as a whole. Kotlin App is about the technology: native Android in Kotlin, migration of old Java code and Kotlin Multiplatform, which lets iOS and Android share business logic. If you need identical logic on both platforms with native interfaces, this is the right service.

What is Kotlin Multiplatform?+

It's a way to write business logic, networking and data handling once in Kotlin and use it on both Android and iOS. The interfaces stay native on each platform. Unlike fully cross-platform frameworks, you can adopt it gradually, starting with a single module.

Should we migrate our Java app to Kotlin?+

Usually yes, but gradually. Kotlin and Java work in the same project, so new code is written in Kotlin and old code is converted as it gets touched. A full rewrite at once is rarely justified.

Kotlin Multiplatform or Flutter?+

It depends on priorities. Flutter shares both logic and interface, which is faster for a new product. Kotlin Multiplatform shares logic but keeps interfaces native, which suits products where native feel matters or native apps already exist.
