The cost of developing an app using Kotlin Multiplatform (KMP) can vary depending on the specifics of the project, such as complexity, features, and design requirements. However, in general, developing a mobile app using a KMP is often about 30% less expensive than building two separate native apps for Android and iOS.
This cost reduction is primarily due to KMP’s ability to share core logic across platforms, reducing duplication of effort while still delivering a native experience on each platform. While every project is different, KMP’s efficiency enabling code sharing typically results in lower development costs and faster timelines compared to traditional native app development.
