Native App Development

Native iOS and Android app development — Swift and SwiftUI for Apple platforms, Kotlin and Jetpack Compose for Android — maximum performance, platform-native UX, and full hardware access.

Overview

Some mobile applications demand the full power of native development: 60fps animations that feel like part of the OS, Bluetooth and NFC hardware integrations, ARKit and ARCore augmented reality features, HealthKit and Google Health Connect data access, real-time audio and video processing, or security-sensitive applications that require Secure Enclave and Android Keystore. We build truly native iOS applications in Swift with SwiftUI and UIKit, and native Android applications in Kotlin with Jetpack Compose — leveraging every platform capability to its fullest.

Native development means your users get an experience that feels exactly right on their device — animations that match platform conventions, navigation patterns that are immediately familiar, and features like Live Activities, Dynamic Island, iOS widgets, Android app shortcuts, and home screen customisation that cross-platform frameworks cannot replicate. Our iOS team follows Apple Human Interface Guidelines precisely and our Android team follows Material Design 3 specifications — so your app passes App Store and Play Store review on first submission.

We have delivered native mobile applications for healthcare wearable integration, industrial IoT monitoring, financial trading platforms, augmented reality retail try-on, and real-time sports scoring — applications where cross-platform compromise was not an option. Performance is profiled throughout development using Instruments on iOS and Android Studio Profiler on Android, eliminating jank, memory leaks, and battery drain before release.

What We Deliver
  • Swift with SwiftUI/UIKit (iOS) and Kotlin with Jetpack Compose (Android) native codebase
  • Platform-native UI following Apple HIG and Google Material Design 3 specifications
  • Hardware integrations: camera, biometrics, Face ID/Touch ID, NFC, Bluetooth LE, GPS
  • In-app purchases and subscriptions via StoreKit 2 and Google Play Billing Library
  • Widgets, Live Activities, push notifications, and deep linking with Universal Links
  • Performance profiling with Instruments (iOS) and Android Studio Profiler throughout build

Why RapideKops?

  • We write real Swift and Kotlin — not wrapped web views or bridged JavaScript
  • Full SwiftUI, Jetpack Compose, WidgetKit, and Live Activities capability from day one
  • Performance profiled on actual hardware throughout development — not simulated environments
  • Beta testing on real physical devices spanning low-end to flagship at every sprint
  • Keychain and Android Keystore used for all credential storage — security by default
  • App Store Optimisation (ASO) keyword research and listing guidance included at launch
How We Work

Our Delivery Process

01

Platform Strategy

We establish the technical approach for each platform, identify platform-specific capabilities to leverage, and align on native UI framework — SwiftUI vs UIKit, Compose vs View.

02

Architecture Design

We design the app architecture (MVVM, Clean Architecture, TCA), define data flow, networking layer, offline storage strategy, and hardware integration approach.

03

Native Build

Platform-dedicated sprints with TestFlight and Firebase distribution so you test on real devices every two weeks — not just at the end of the project.

04

Optimise & Submit

Instruments and Android Profiler sessions eliminate performance bottlenecks. App Store and Play Store submissions managed end-to-end by our team.

Common Questions

Frequently Asked Questions

When do we absolutely need native development rather than cross-platform?
Choose native when you need: deep hardware integration (ARKit, Core NFC, Bluetooth LE peripherals), platform-exclusive features (Live Activities, Dynamic Island, Android widgets), maximum graphics performance (60fps custom animations, Metal), sensitive security requirements (Secure Enclave, Android StrongBox), or integration with system-level APIs like HealthKit or Google Health Connect that cross-platform bridges do not fully expose.
What is the difference between SwiftUI and UIKit, and which do you use?
SwiftUI is Apple's modern declarative UI framework — faster to write, great for new projects, and the future of iOS development. UIKit is the mature imperative framework with broader API coverage and better support for complex interactions. For new projects, we default to SwiftUI. Where SwiftUI has gaps, we bridge to UIKit components. For existing UIKit codebases, we migrate incrementally.
Can you add widgets and Live Activities to our existing native app?
Yes. WidgetKit widgets, Lock Screen widgets, and Live Activities for ongoing events are capabilities we implement as standalone features. They require a separate Widget Extension target in Xcode and a shared App Group for data sharing between the main app and the widget — we handle the full configuration.
How do you handle in-app subscriptions and payments in native apps?
iOS: StoreKit 2 for product definition, purchase flow, receipt validation, and subscription status tracking. Android: Google Play Billing Library 6+ for the equivalent. For apps with both web and mobile subscriptions, we implement a unified subscription status API so your backend is the source of truth.
How do you test native apps across different devices and OS versions?
We maintain a device farm spanning iPhone SE (smallest screen), mid-range iPhones, and the latest Pro model for iOS, and equivalent Android coverage from budget to flagship. Every sprint build is distributed via TestFlight (iOS) and Firebase App Distribution (Android) for testing on physical hardware.
