What it is

What you're actually getting.

Native is the right choice when performance, hardware integration, or platform-specific feel are not negotiable. We ship Swift and Kotlin apps that earn the choice.

Who it's for

Is this the right fit for you?

This is a good fit when…

  • You need hardware capabilities (camera, sensors, ARKit, BLE) that cross-platform doesn't reach well.
  • Performance and frame timing requirements rule out a JavaScript runtime.
  • Your brand demands platform-specific feel , Cupertino on iOS, Material on Android.

You probably don't need this yet if…

  • One shared cross-platform app would meet your needs for less.
  • You're validating an idea and speed to market matters most.

How it works

A clear path from first call to launch.

  1. Two teams, one product

    Experienced iOS and Android engineers working in parallel, with shared design and product. Code is platform-idiomatic; product behavior is platform-aware.

  2. Modern stacks

    Swift, SwiftUI, modern Concurrency on iOS. Kotlin, Compose, Coroutines on Android. We don't ship 2018 patterns.

  3. Performance discipline

    Frame timing, memory, and battery budgets locked per device class. Instruments and Profiler are daily tools.
