Mixed Apps
Kotlin Multiplatform

Android and iOS apps built on a shared foundation

Kotlin Multiplatform is our main technology for cross-platform development. We build the shared parts of an app once and handle platform-specific features where they are needed. You get an app for both Android and iOS, with less duplication as it grows.

Shared foundation

What your app can share

Shared logic and data

Server communication, data handling and business rules can be shared between Android and iOS, so changes to the shared part don't have to be built twice.

UI that fits the project

The user interface can stay native on each platform, or we can share it with Compose Multiplatform. We choose based on the product and its users.

Access to device features

We extend the shared foundation with platform-specific code, for example for the camera, notifications or other device capabilities.
Choosing the technology

When Kotlin Multiplatform makes sense

It suits products that offer similar features on Android and iOS, work with the same data and are meant to evolve over the long term. We decide how much code to share based on your actual requirements.

What we discuss before choosing the technology

If you only target one platform, need different interfaces or require extensive integration with specific devices, we compare KMP with native development. The savings depend on how much code can really be shared. Both apps still need to be tested and released separately.
