iOS Development Android Development Platform-specific

Custom native app development

Building a native app means building with the languages and tools that Apple and Google themselves prescribe: Swift for iOS, Kotlin for Android. No compromises on performance, no workarounds for platform features. We develop native apps that make full use of the potential of each operating system, from smooth animations and offline functionality to deep integration with hardware and OS services.

Whether you want to build a consumer app for millions of users or an internal enterprise tool that must work beyond the reach of Wi-Fi, native development gives you the control that cross-platform frameworks cannot offer. We take on the entire process, from UX research and app design to publication in the stores and ongoing maintenance.

What we do: native app development from concept to launch

Native app development is about building applications designed specifically for a single platform. Unlike cross-platform frameworks, a native app has direct access to all of the operating system's APIs, sensors and UI components. This translates into faster load times, smoother interactions and a user experience that feels as though the app belongs on the device.

We don't just build the app itself; we also think along about the complete digital architecture. How does the app communicate with your backend? Which data needs to be available offline? How do we scale as the user base grows? We answer these questions in the discovery phase, so the technical foundation is sound before we write the first line of code.

From idea to the App Store and Google Play

We guide you through the entire development process. Together we map out your requirements, design the user experience, build the app in platform-specific code and make sure it launches successfully on the App Store and Google Play Store. After launch, we're on hand for monitoring, updates and further development.

Our approach is iterative: we work in sprints of two to three weeks, deliver working software at the end of each sprint and feed your feedback straight into the next cycle. That way you stay in control of the result, and we avoid spending months building something that doesn't match what you had in mind.

Our specialisms in native app development

Each platform has its own ecosystem, its own design guidelines and its own technical capabilities. We're skilled in both and advise you on the best strategy for your audience and business model.

Apple ecosystem

Building an iOS app

We build iOS apps in Swift using the latest Apple frameworks. From iPhone and iPad to Apple Watch extensions, your app follows the Human Interface Guidelines and makes use of features such as Face ID, Core ML, HealthKit and ARKit. The result is an app that feels like a natural part of the Apple ecosystem and performs optimally on every Apple device.

  • Swift and SwiftUI as primary languages
  • Core Data for offline storage
  • Push notifications via APNs
  • TestFlight for beta distribution
Google ecosystem

Building an Android app

For the Android platform we work with Kotlin and Jetpack Compose. Android runs on thousands of different devices with a wide range of screen sizes and hardware specifications. We make sure your app performs well everywhere through responsive layouts, Material Design 3 guidelines and background processing with WorkManager. We also integrate seamlessly with Google services such as Maps, Firebase and Google Pay.

  • Kotlin and Jetpack Compose
  • Room database for local storage
  • Firebase Cloud Messaging
  • Google Play Console for distribution
Strategy

Native or cross-platform?

Not every project requires two entirely separate codebases. Sometimes a cross-platform solution with Flutter or React Native is more cost-effective, particularly if the app mainly uses standard UI elements and doesn't need deep hardware integration. We help you make the right call based on your audience, budget, required functionality and long-term plans, without bias towards any one technology. Sometimes we even recommend a hybrid approach: a shared business logic layer with native UI per platform.

  • Independent advice for each project
  • Cost-benefit analysis of native vs. cross-platform
  • Strategy for a phased rollout
  • Shared backend architecture

Uses of native apps

Native apps are ideally suited to applications where performance, security or deep hardware integration is critical. Direct access to platform APIs opens up possibilities that simply aren't achievable with web apps or hybrid solutions. Below are the areas where we see the greatest impact. You can also explore our custom software capabilities.

Enterprise

Enterprise and field service apps

Internal apps for field staff, warehouse management or sales teams that also need to work offline. Native offers reliable background processing, fast data synchronisation and integration with business systems via API integrations. Think camera-based scanning, GPS tracking and push notifications for real-time updates.

A typical scenario: a field engineer receives work orders, adds photos to a report and updates the status, all without a stable internet connection. The app synchronises automatically as soon as coverage returns. That requires a robust local database and conflict resolution, which native platforms support far better than webviews.

Consumer

Consumer and e-commerce apps

End users expect fast, fluid interfaces with animations that feel like part of the operating system itself. Native code delivers that experience without frame-rate drops. Ideal for loyalty programmes, ordering platforms and media apps where engagement and retention make the difference. Think of smooth scrolling behaviour, haptic feedback, home screen widget support and seamless integration with the operating system's share sheet: details users expect without thinking, but notice immediately when they are missing.

IoT & Hardware

IoT-connected apps

Apps that communicate with physical devices via Bluetooth Low Energy, NFC or Wi-Fi Direct need direct access to hardware APIs. Native development gives full control over connection protocols, battery consumption and background processing. Think smart home control, wearables or industrial sensors. The app must be able to receive data continuously in the background, scan energy-efficiently for nearby devices and respond reliably to events, which is exactly where native frameworks excel.

Regulated

Healthcare and regulated apps

In sectors such as healthcare and fintech, strict requirements apply regarding data security and compliance. Native apps provide access to platform-specific security layers such as the iOS Keychain and Android Keystore, biometric authentication and certificate pinning, which are essential for apps handling sensitive data. The ability to store data encrypted locally, without cloud dependency, is also an important factor in these sectors.

Why Appfront for native app development?

Building native apps calls for a team that not only masters Swift and Kotlin, but also understands how an app fits within your broader digital strategy. We combine technical depth with a pragmatic, results-driven approach suited to the Dutch market.

Our approach

Discovery → Design → Development → Testing → Launch → Growth

Agile sprints, transparent communication

Platform expertise

Our team works daily with the latest SDKs, frameworks and design guidelines from Apple and Google. We follow WWDC and Google I/O closely and apply new capabilities as soon as they are stable and production-ready. Your app is built with current technology, not legacy solutions that will be deprecated within two years. See our full range of services for the bigger picture.

  • Experience with Swift, SwiftUI, Kotlin and Jetpack Compose
  • Knowledge of platform-specific design patterns
  • Rapid adoption of new OS versions and features

More than just the app

An app does not exist in a vacuum. We also build the backend systems, APIs and integrations that power your app. From authentication and payments to real-time data and AI functionality, everything comes from one team. This prevents alignment problems between frontend and backend developers and considerably speeds up the development process. You have a single point of contact for the complete product.

  • Backend development and API design
  • CI/CD pipelines for automated testing and deployment
  • Post-launch maintenance and ongoing development

Tools and technologies we use

We work with proven tools and frameworks recommended by Apple and Google. No experimental libraries that will no longer be maintained in a year's time, but the standard toolchain that guarantees stability and long-term support. Below is an overview of the core technologies we use daily when building native apps for our clients.

Security and compliance

A native app often handles sensitive data: personal details, payment information or business-critical information. We don't add security as an afterthought; we build it into the foundation of the architecture. Both Apple and Google set strict requirements for apps in their stores, and those requirements become stricter every year. Our apps are prepared for this from day one.

  • Full GDPR compliance in data processing and storage
  • App Store and Google Play review compliance from day one
  • Biometric authentication (Face ID, Touch ID, fingerprint)
  • Certificate pinning for secure API communication
  • Encrypted local storage via iOS Keychain and Android Keystore
  • OAuth 2.0 and OpenID Connect for authentication
  • Jailbreak and root detection as an additional layer of security

Frequently asked questions about native app development

What is the difference between native and cross-platform app development? +
With native development, a separate app is written for each platform (iOS and Android) in the language that platform prescribes: Swift for iOS, Kotlin for Android. Cross-platform frameworks such as React Native or Flutter use a single shared codebase for both platforms. Native generally delivers better performance, smoother animations and direct access to all platform APIs, without the limitations of an intermediate layer. Cross-platform can be more cost-effective if the app needs less platform-specific functionality and fast time-to-market is the priority.
When should you choose a native app? +
A native app is the best choice when performance is critical, when you need deep hardware integration (Bluetooth, camera, sensors, GPS), when the app requires complex animations or real-time processing, or when you need maximum security for sensitive data. If you are building for one platform only, native is also the logical choice, as there is no framework overhead. Native is also ideal for apps that make intensive use of OS-specific features such as widgets, Siri Shortcuts or Android App Links.
How long does it take to build a native app? +
The lead time depends on the complexity and scope. An MVP can be ready in a few weeks to a few months. A fully developed app with a backend, integrations and two platforms usually takes longer. We work in sprints so you can test a working version early and give feedback. We always draw up a realistic plan after the discovery phase.
What determines the cost of native app development? +
The main cost factors are: the number of platforms (iOS, Android or both), the complexity of the functionality, the extent of backend development and API integrations, the design (standard vs. custom UI), and whether special features are needed, such as an offline mode, real-time data or biometric authentication. We always prepare a detailed quote following an intake meeting, so you know exactly what to expect upfront.
Do you build for both iOS and Android? +
Yes, we develop for both platforms. For each project, we advise whether it makes sense to start with one platform and expand later, or to build for both at once. Sometimes we even recommend a cross-platform approach if that better suits your budget and functional requirements. We always make that honest assessment together with you.
What about maintenance after launch? +
Once your app is live, ongoing maintenance is essential. Apple and Google release new OS versions every year, which may require adjustments to your app — think privacy changes, new APIs or deprecated features. There are also security updates, bug fixes and feature improvements based on user feedback and analytics. We offer maintenance contracts so your app stays up to date, secure and compatible with the latest devices and OS versions. We also support the further development of new features and the optimisation of your app based on user data.
