The Problem We're Solving

Cross-platform frameworks can't access everything

❌ The Cross-Platform Limitation

  • Limited access to latest platform APIs and features
  • Performance bottlenecks from JavaScript bridge overhead
  • Complex native modules needed for platform-specific features
  • Apps feel "close but not quite" native to users
  • Waiting for framework updates to support new OS features

✅ The Native.fast Way

  • Full access to every iOS and Android API day one
  • Maximum performance-code runs directly on device
  • Use SwiftUI, UIKit, Jetpack Compose natively
  • Apps feel indistinguishable from platform-native
  • Adopt new OS features immediately at launch

How It Works

Platform-native development with modern tooling

iOS Native (Swift)

Build with Swift and SwiftUI for modern iOS apps. Full access to UIKit, CoreData, CloudKit, HealthKit-every Apple framework. Xcode integration with live previews, SwiftUI canvas, and Instruments profiling.

Android Native (Kotlin)

Develop with Kotlin and Jetpack Compose for modern Android. Direct access to Android SDK, Room, WorkManager, CameraX. Android Studio with layout inspector, profiler, and instant hot reload.

Shared Architecture

Share business logic and data models while keeping UI platform-specific. Kotlin Multiplatform for code sharing. Write once for networking, database, authentication-UI stays truly native.

Native Platform Features

Full access to platform capabilities

Platform API Access

Direct access to every iOS and Android API. ARKit, CoreML, HealthKit on iOS. CameraX, MLKit, WorkManager on Android. No waiting for framework wrappers-use platform features immediately at OS launch.

Maximum Performance

Code compiles directly to native ARM/x86. No JavaScript bridge overhead. 120fps on ProMotion displays. Metal rendering on iOS, Vulkan on Android. Performance indistinguishable from Objective-C/Java apps.

Native UI Components

SwiftUI and UIKit on iOS. Jetpack Compose and XML layouts on Android. Platform-specific navigation patterns, gestures, and animations. Apps feel 100% native because they are.

Shared Business Logic

Kotlin Multiplatform lets you share networking, data models, and business rules. Write once for API clients, database schemas, authentication flows. UI stays platform-specific for best UX.

Platform IDEs

Xcode for iOS with SwiftUI previews, Interface Builder, Instruments profiler. Android Studio with layout inspector, memory profiler, network inspector. Best-in-class tooling for each platform.

Instant OS Adoption

Adopt new iOS and Android features day one. Widgets, Live Activities, Dynamic Island on iOS. Widgets, Predictive Back on Android. No waiting months for cross-platform frameworks to catch up.

Why Choose Native Development

Maximum platform capabilities and performance

Uncompromised Performance

Code compiles directly to native ARM. Zero JavaScript bridge overhead. 120fps on ProMotion displays. Metal and Vulkan rendering. Performance identical to apps written in Objective-C/Java-because it is native code.

Full Platform Access

Every iOS and Android API available immediately. ARKit, CoreML, HealthKit, CameraX, MLKit, WorkManager. No waiting for cross-platform wrappers. Adopt new OS features day one at WWDC/Google I/O.

True Native UX

SwiftUI and Jetpack Compose for modern declarative UI. Platform-specific navigation, gestures, animations. Apps feel indistinguishable from first-party apps. Users can't tell-and that's the point.

Shared Logic Possible

Kotlin Multiplatform lets you share business logic while keeping UI native. Write networking, data models, auth once. Best of both worlds-code reuse where it matters, platform-specific UI where it counts.

Native Development Success Stories

Platform-specific apps that deliver

AR Shopping: Native ARKit + ARCore

Furniture retailer built AR preview using native ARKit on iOS, ARCore on Android. Customers visualize products in their space before buying. 60fps tracking, realistic lighting, shadow rendering. 45% increase in conversion, 70% reduction in returns. Cross-platform frameworks couldn't deliver this performance.

Health Tracking: CoreML + ML Kit Integration

Fitness app uses CoreML for on-device workout analysis on iOS, ML Kit on Android. Privacy-preserving ML runs locally-no data sent to cloud. HealthKit integration syncs with Apple Health, Health Connect on Android. 10M users trust platform-native health APIs.

Banking: Platform Biometrics + Secure Enclave

Digital bank uses Face ID and Secure Enclave on iOS, BiometricPrompt and Keystore on Android. End-to-end native security APIs. Transactions authenticated with platform biometrics. 99.97% fraud prevention. Native security frameworks provide guarantees cross-platform can't match.

Video Editing: Metal + Vulkan Rendering

Professional video app uses Metal on iOS, Vulkan on Android for GPU-accelerated rendering. Real-time 4K effects at 60fps. Export times 10x faster than software rendering. Platform-native graphics APIs unlock hardware capabilities impossible with abstraction layers.

Navigation: MapKit + Google Maps Native SDKs

Ride-sharing app uses MapKit on iOS, Google Maps Android SDK. Native map rendering, turn-by-turn navigation, traffic overlays. Background location updates don't drain battery. 50ms latency for real-time driver tracking. Native location APIs optimize for each platform's power management.

Wearables: WatchOS + Wear OS Apps

Productivity app extends to Apple Watch and Wear OS with native companion apps. Complications, standalone functionality, offline sync. WatchKit and Wear APIs provide experiences cross-platform frameworks can't replicate. 3M wearable users rely on platform-native watch apps.

Native Development Best Practices

Build platform-optimized apps

Follow Platform Guidelines

Human Interface Guidelines for iOS, Material Design for Android. Use platform-native navigation patterns, gestures, and components. Apps that feel native pass App Store review faster and get better ratings.

Optimize for Performance

Profile with Instruments (iOS) and Android Profiler. Fix memory leaks, optimize images, lazy-load content. Target 60fps animations, sub-100ms touch response. Users abandon apps that feel sluggish.

Test on Real Devices

Simulators don't catch everything. Test on actual iPhones and Android phones with varying specs. Check oldest supported devices for performance issues. Real devices reveal touch, camera, and sensor bugs.

Handle Platform Differences

iOS and Android have different back button behaviors, permission models, and lifecycle events. Embrace differences rather than forcing one pattern. Platform-specific code makes apps feel natural to users.

Adopt New OS Features Early

Support latest iOS/Android features at launch. Widgets, Live Activities, Dynamic Island. Users with new devices expect cutting-edge features. Native development lets you ship day one.

Monitor Crashes and ANRs

Integrate Crashlytics or Sentry from day one. Track crash-free sessions, ANRs (Application Not Responding) on Android. Fix crashes immediately-they hurt store rankings and user trust.
