Why KMP?

We chose Kotlin Multiplatform because event discovery has complex business logic (geo-spatial search, event aggregation, user preferences) but relatively standard UI patterns. KMP lets us share 80% of the code while keeping native performance and platform-specific UX where it matters.

Sub-100ms geo-spatial search. One codebase. Two platforms. No compromises.
