When to Use and When Not to Use Cross-Platform App Development

As I pointed out earlier, cross-platform app development is a smart path for businesses aiming to reduce expenses, speed up product launches, and attract a broader audience. Still, there are cases where this method might not be suitable. Below, I’ve listed some situations that can guide you on when to embrace it and when to hold back.

When Cross-Platform Development is the Best Choice

• Budget and Time Constraints - This approach is perfect for startups or anyone looking to launch a minimum viable product. It enables faster development and cuts down on maintenance costs, all thanks to a single codebase.
• Same App Logic Across Platforms - If your app doesn’t need platform-specific UI or features, this is the way to go. Many companies opt for cross-platform app development for content-driven apps, dashboards, CRM systems, or social media platforms.
• Wider Audience - If your goal is to reach as many users as possible, cross-platform apps are a smart choice since they can be launched on both iOS and Android at the same time. When time is tight and you need to get your project out the door quickly, cross-platform development is the way to go.
• Popular Cross-Platform Networks - For businesses using frameworks like Flutter, React Native, or Kotlin Multiplatform, cross-platform development is a fantastic option. These frameworks provide high performance, a near-native user interface, and allow access to native APIs through plugins or bridging.
• Web-First Teams - Companies with in-house JavaScript or Dart developers should think about cross-platform app development. This way, there’s no need to hire iOS specialists or Android specialists.
• For Internal Tools or Enterprise Purposes - When creating an app for internal company use, UI/UX standards often take a backseat. Developers can focus on rolling out products quickly and efficiently, using fewer resources.

When Cross-Platform App Development is Not the Best Choice

• High-Performance Apps - When it comes to building high-performance or hardware-intensive apps, think real-time video or audio processing, 3D graphics, or AR/VR, along with low-latency animations or high frame rates, cross-platform app development just doesn’t cut it. That’s where Switt for Kotlin shines, giving you complete control over your app’s performance.
• Platform-Specific UI/UX Components - Now, let’s talk about platform-specific UI/UX components. iOS and Android are distinct platforms, each with its own user habits and design guidelines. An app might look the same on both, but it could miss out on key features or lag during animations. This can frustrate users, leading to uninstalls or negative reviews.
• Constant Access to Native SDKs and Low-Level APIs - When it comes to apps that need constant access to device features like Bluetooth, the camera, or sensors, cross-platform development might not be the best route. Cross-platform plugins often lag behind native SDKs in updates, meaning new features might not make it into your app right away. This can lead to extra work for companies trying to customize their apps.
• Scaling With Extensive Features - Scaling complex apps can also be tricky due to codebase abstraction and plugin dependencies. Developers might find themselves writing more bridging code to make up for the limitations of cross-platform tools, which can drive up maintenance costs, slow down performance, and increase the time spent on fixing bugs.
• Deep Integration With OS Features - To truly tap into unique OS features, developers often have to write platform-specific code. Think iOS-only widgets or shortcuts and Android-specific intents and custom launchers. In these cases, going for native development is usually the way to go, as it allows for smoother and more timely integration.
• Advanced Security Needs - Finally, industries like healthcare, finance, or government have to adhere to strict security measures and regulations. This makes it crucial to choose the right development approach to ensure compliance and protect sensitive data.

Ending Thoughts

Cross-platform app development may seem like a shortcut to many individuals. Writing a single code for all platforms, speedier development, quicker product to market, and lower costs are the benefits, but companies must also consider the cons of cross-platform development. Compared to native apps, cross-platform apps usually don’t match the level of performance in terms of speed, memory usage, and animation smoothness.

The solution lies in adopting a hybrid approach where one leverages cross-platform development for basic features and writes custom code only when required. Developers must use mature frameworks like Flutter and React Native. While Flutter is great for high-performance UIs, React Native allows developers to write a large chunk of the code in JavaScript or TypeScript. Not only does this enable the reuse of 90 to 95 percent of the code, but it also speeds up development while cutting costs. Rigorous testing is also a must.
