Mobile App Development
Native App Development Company
iOS in Swift. Android in Kotlin. Maximum Platform Performance.
We build native iOS and Android apps using Swift/SwiftUI and Kotlin/Jetpack Compose — full platform API access, 60fps performance, App Store and Google Play ready. US-managed team, delivered in 8–20 weeks.
What Is Native App Development?
Native app development means building a mobile app using a platform's official programming language and tools — Swift/SwiftUI for iOS and Kotlin/Jetpack Compose for Android. A native app runs directly on the device's operating system with no translation layer, giving it the fastest possible performance, full access to every device API, and a UI that behaves exactly as users expect on their platform.
The alternative is cross-platform development (Flutter, React Native), which shares one codebase across both iOS and Android. Native is the right choice when performance, cutting-edge platform APIs, or pixel-perfect UI quality are non-negotiable.
Native iOS & Android Development
iOS: Swift & SwiftUI
Modern native iOS development with Swift and SwiftUI. Full Apple platform API access — HealthKit, ARKit, Core ML, Apple Pay, Face ID, Sign in with Apple, watchOS.
Android: Kotlin & Jetpack Compose

Store-Ready & Compliant
App Store and Google Play submission, review guideline compliance, data safety declarations, HIPAA/PCI-DSS architecture, and ongoing OS version compatibility.
Native vs Cross-Platform: How to Choose
Both approaches produce high-quality apps. The right choice depends on your performance requirements, budget, and timeline.
| Factor | Native (Swift / Kotlin) | Cross-Platform (Flutter / RN) |
|---|---|---|
| Performance | Maximum — runs directly on OS | Very good — small overhead from runtime |
| Platform API access | Full, day-one access to new APIs | Good — some APIs need native modules |
| UI quality | Pixel-perfect platform feel | Excellent — near-native on modern frameworks |
| Development cost | Higher — two codebases | 40–60% lower — shared codebase |
| Time to market | Slower — parallel builds | Faster — one sprint cycle for both |
| Maintenance | Two separate update cycles | One codebase to maintain |
| Team needed | iOS + Android specialists | Flutter or React Native generalist |
| Best for | Performance-critical, API-heavy apps | Most apps, budget-conscious, fast MVPs |
When Should You Choose Native App Development?
Not sure? If your app is a consumer marketplace, FinTech product, healthcare patient app, on-demand service, or enterprise tool — cross-platform (Flutter or React Native) almost certainly covers your requirements at significantly lower cost. We help you make the right call before you commit to either approach.

Native App Development FAQ
What is native app development?
Native app development means building a mobile app specifically for one platform — iOS or Android — using that platform's official programming language and tools. iOS native apps are built with Swift and SwiftUI using Xcode. Android native apps are built with Kotlin and Jetpack Compose using Android Studio. A native app runs directly on the device's operating system without a translation layer, which gives it faster performance, full access to device hardware (camera, GPS, biometrics, sensors), and a UI that feels exactly like the platform it runs on.
What is the difference between native and cross-platform app development?
Native app development builds a separate codebase for each platform (one for iOS in Swift, one for Android in Kotlin). Cross-platform development (Flutter, React Native) builds one shared codebase that compiles to both platforms. Native gives you maximum performance, the deepest platform API access, and the most polished UI at the cost of maintaining two codebases. Cross-platform cuts development cost 40–60% with 80–95% shared code but has some limitations on deeply platform-specific APIs and occasionally falls slightly behind the latest OS features. Most apps work well cross-platform; native is worth the extra cost when you need top-tier performance, cutting-edge Apple/Google APIs, or apps where the "feels native" quality is a product differentiator.
How much does native app development cost?
Native app development cost depends on platform, complexity, and team location. A native iOS or Android MVP (one platform) costs $25,000–$60,000 with a US-managed offshore team like Ortem. Building natively for both iOS and Android separately costs $50,000–$120,000. A US or UK in-house or local agency build typically costs 3–4x more: $80,000–$250,000 for a mid-complexity app. Ongoing maintenance adds 15–20% of the initial build cost per year. The main cost driver for native vs cross-platform is that you are effectively funding two engineering tracks instead of one.
How long does native app development take?
A native mobile MVP for one platform (iOS or Android) takes 8–12 weeks from design kickoff to store submission. A more feature-complete app with custom integrations, real-time data, and payment flows takes 14–20 weeks per platform. Building natively for both iOS and Android in parallel with two separate teams takes 14–20 weeks total (not double), as design, API development, and QA are shared. The sprint-based approach at Ortem means you see working software on device every two weeks throughout the project.
When should I choose native over cross-platform?
Choose native when: (1) You need deep access to platform-specific APIs — ARKit, Core ML, HealthKit, or Face ID on iOS; Camera2, Wear OS, Android Auto, or NFC on Android. (2) Your app has demanding performance requirements — real-time video processing, complex animations, augmented reality, or high-frequency sensor data. (3) UI quality is a core product differentiator and you need the app to feel indistinguishable from a first-party platform app. (4) You are building for Apple Watch (watchOS) or Android Wear exclusively. For most consumer apps, FinTech apps, healthcare apps, and enterprise tools, cross-platform (Flutter or React Native) delivers equivalent quality at significantly lower cost.
What languages are used for native app development?
iOS native apps are built with Swift (the primary language since 2014) and SwiftUI (the modern declarative UI framework from 2019). Legacy iOS apps may use Objective-C, but all new development and modernization uses Swift. Android native apps are built with Kotlin (the primary language since Google made it official in 2017) and Jetpack Compose (the modern declarative UI framework from 2021). Legacy Android apps may use Java, but all new development uses Kotlin. Ortem uses Swift/SwiftUI for iOS and Kotlin/Jetpack Compose for Android on all new native projects.
What are the advantages of native app development?
The main advantages of native app development are: (1) Performance — native code runs directly on the OS without a JavaScript bridge or rendering layer, giving the fastest possible execution. (2) Platform API access — every new iOS and Android API is available immediately on the day of release, with no waiting for cross-platform framework support. (3) UI fidelity — native components match the exact behavior, animations, and conventions users expect on their platform. (4) Battery and memory efficiency — native apps have lower overhead than cross-platform runtime environments. (5) App Store optimization — Apple and Google both give preferential treatment to apps that follow their platform guidelines, which native apps naturally do.
