How to choose between native and cross-platform

The fundamental difference between native and cross-platform development lies in the target operating systems. Native mobile development involves creating applications specifically designed for either Android or iOS, using the programming languages and tools native to each platform. Conversely, cross-platform development allows you to build applications from a single codebase that can run on multiple operating systems simultaneously.

The decision depends on several factors, including your target audience, budget, development timeline, desired performance, and security requirements. Native development offers optimized performance and seamless integration with device hardware, while cross-platform solutions promise quicker deployment and more efficient code reuse. To understand the nuances, it’s important to examine what each approach entails and how they are created.

What is a native mobile application?

Native applications are built specifically for a particular platform—Android or iOS—using the programming languages and SDKs designated for those systems. For Android, developers typically use Java or Kotlin, with Kotlin support introduced officially in 2017. Java was the original language for Android development, but Kotlin has become the preferred choice due to its modern features and concise syntax.

For iOS, native apps are developed using Objective-C or Swift. Objective-C has been used since the early days of iOS development, while Swift, introduced by Apple in 2014, has rapidly gained popularity due to its speed, safety features, and ease of learning. Apple claims that Swift performs significantly faster than Objective-C, making it ideal for performance-critical applications.

Some well-known native apps include Google Maps, Pinterest, Spotify, and WhatsApp, which leverage platform-specific features to deliver optimal user experiences.

Native app tools

Developers working on native Android apps typically rely on Android Studio or IntelliJ IDEA, both of which run on Windows, macOS, and Linux. For iOS applications, Xcode and AppCode are the primary IDEs, but these are only available on macOS. These tools provide comprehensive SDKs, debugging, and performance analysis features essential for native development.

Pros of native mobile applications

  • Superior performance: Native apps are optimized for their specific platform, ensuring fast, responsive, and efficient user interactions.
  • Enhanced security: Native development allows integration with platform-specific security features, safeguarding user data.
  • Consistent UX: Native applications adhere to the design guidelines of their respective OS, resulting in a natural and intuitive user experience.
  • Full hardware feature access: Native apps can utilize all device capabilities, including sensors, push notifications, camera, GPS, and more.
  • Timely SDK updates: Developers gain immediate access to the latest SDKs, APIs, and platform improvements, reducing bugs and enhancing stability.

Cons of native mobile applications

  • Higher costs: Developing separate apps for Android and iOS requires dedicated teams proficient in different programming languages, increasing labor costs.
  • Longer development cycle: Maintaining and updating multiple codebases can slow down deployment and complicate updates.
  • Limited code reuse: Developers must create and maintain distinct codebases, leading to duplicated efforts and increased complexity.

What is a cross-platform mobile application?

Cross-platform apps are built from a shared codebase that targets multiple operating systems, primarily Android and iOS. Using frameworks like React Native, Flutter, or .NET MAUI, developers write code once and deploy it across platforms, utilizing platform-specific SDKs through an abstraction layer.

Popular frameworks include:

  • React Native (by Meta), which uses JavaScript.
  • Flutter (by Google), which uses Dart.
  • .NET MAUI (by Microsoft, formerly Xamarin), which uses C# and XAML.

These frameworks compile code into native UI components, providing an experience that closely resembles native apps. They also facilitate access to device sensors such as GPS, camera, microphone, and battery status, ensuring a rich feature set.

Examples of cross-platform applications include Instagram, Skype, Walmart, and Airbnb (React Native); Google Ads, eBay Motors, and the New York Times (Flutter); and The World Bank, Fox Sports, and BBC Good Food (Xamarin).

Cross-platform tools

To develop cross-platform apps, developers need the corresponding SDKs and IDEs. For Android, this includes Android SDKs and tools like Android Studio or Visual Studio Code. For iOS, Xcode and macOS are mandatory. Cross-platform frameworks integrate with these tools to streamline development:

  • React Native: Visual Studio Code, Android Studio, WebStorm, Xcode.
  • Flutter: Visual Studio Code, Android Studio, IntelliJ.
  • Xamarin/.NET MAUI: Visual Studio.

Pros of cross-platform mobile applications

  • Lower development costs: A single team can develop for multiple platforms, reducing the need for separate specialized teams.
  • Code reusability: Shared codebases ensure consistency and simplify maintenance.
  • Faster time-to-market: Reusing code accelerates development cycles and testing.
  • Simplified updates: Managing one codebase makes deploying updates across platforms more straightforward and synchronized.

Cons of cross-platform mobile applications

  • Larger app size: Cross-platform frameworks often add extra runtime layers, increasing app size.
  • Limited hardware integration: Some device-specific features may be difficult or impossible to access without native code.
  • Performance trade-offs: Cross-platform apps may experience slower performance compared to native counterparts, especially for resource-intensive tasks.
  • Delayed access to new platform features: When OS updates are released, cross-platform frameworks may require additional updates to support new features.

Native versus cross-platform apps: Which is best?

Choosing between native and cross-platform development hinges on your specific project needs, resources, and goals. Each approach offers unique advantages and challenges, making it essential to evaluate the key factors influencing your decision.

Time to market

For startups or projects requiring rapid deployment, cross-platform development can significantly shorten the development cycle. It allows for simultaneous deployment across multiple platforms, enabling early user feedback and quicker iterations. Native development, while offering optimized performance, often takes longer due to separate codebases and development teams.

Security

Security is paramount for applications handling sensitive data, such as banking or healthcare apps. Native development provides access to platform-specific security features like file encryption and biometric authentication, making it a better choice for high-security requirements. Cross-platform apps, while improving, may face limitations in leveraging certain security features fully.

Performance

Apps that demand high computational power—such as games or real-time processing applications—benefit from native development, which ensures optimal use of hardware resources. Cross-platform frameworks might introduce performance overhead due to additional abstraction layers, potentially impacting responsiveness and efficiency.

Development costs

Budget constraints influence the choice. Cross-platform solutions reduce costs by maintaining a single codebase and fewer developers. However, native apps, though more expensive, may provide better performance and security, justifying the higher investment for critical applications.

Conclusion

Deciding whether to develop a native or cross-platform mobile app depends on the unique requirements of your project. Factors such as target audience, desired performance, security needs, budget, and timeline should guide your choice. While both approaches have their merits, understanding their differences helps ensure your app aligns with your strategic goals.

Remember, there is no universal solution—each project is distinct. Continually evaluate your specific needs, future scalability, and maintenance considerations when choosing your development approach. For businesses aiming to streamline their deployment processes and improve efficiency, exploring options like continuous integration and deployment with tools such as CircleCI can provide significant advantages in accelerating app delivery.
