Cross-platform mobile app development: Value vs. compromise

So, you're thinking about building an app.

Great! But here's the core question: Do you build one app that (hopefully) works everywhere, or multiple apps, each specifically designed for iOS, Android, and emerging platforms like web and desktop?

That’s where cross-platform app development comes in, and why businesses are seeking cross-platform development services.

The promise is simple: write your code once, and then deploy it to different platforms. But what's the real story? Is it a smooth path to success, or are there hidden challenges?

Let's start with why this is even a conversation. Here's the two main reasons we often see, and why they're more powerful than you might think:

• Budget optimization: Let's be real. Building separate native apps for iOS and Android? That means two development teams, two codebases, double the testing... it gets expensive. With cross-platform, you can cleverly optimize your development process, potentially reducing the time and resources required to reach both audiences. Instead of viewing it as a cost-cutting measure, see it as a strategic use of your budget.
• You need to move fast: Speed is often crucial, especially for startups and innovative businesses. Cross-platform development can help you get your app into the hands of users faster, allowing you to gather valuable feedback and iterate quickly.

With that said, it's important to acknowledge that advancements in development tools and frameworks have enabled cross-platform apps to overcome historical limitations, now achieving flexibility, adaptability, stability, high performance, broad functionality, and compelling UX.

With all of these positive incentives, how can it not be the best option?

This is where things get complicated. Yeah, you can share code, but that doesn't mean it's always easy. The differences between the ux on each platform are subtle but noticeable.

Of course, there are many positive benefits you can get from native apps too.

While cross-platform offers tremendous potential, it's important to be aware of the challenges:

Platform-specific tweaks are often necessary: iOS and Android behave differently. Sometimes you can paper over those cracks, other times you need to write specific code for each platform, anyway. Now that codebase that was meant to have one single set of code, has a bunch of “if” statements checking for the device and running slightly altered code.

1. Performance can suffer: Native apps are built from the ground up for a specific OS. Because they're tailored to the hardware and software, they can run faster and more efficiently. In contrast, cross-platform apps aim to work on multiple systems, often using a "middleman" that translates instructions. This translation process can sometimes slow things down, especially when the app is doing something complicated or resource-intensive.
2. The "native look and feel" isn't always there: Users can usually tell when an app isn't truly native. A weird animation, a slightly-off UI element... it all adds up.
3. Limitations in cross platform apps: You will not be able to use some native features in your app if you're using a cross platform service.

Alright, so you are still interested and want to build cross platform mobile apps.

What are the main options?

At ZenDev, we've guided numerous clients through this decision process, helping them balance business needs with technical possibilities.

Let's break down some of the most popular frameworks, and share some practical insights from our experience in the field:

React Native

React Native, maintained by Meta (formerly Facebook), continues to be a top choice for cross-platform development. It uses JavaScript and React, making it accessible to web developers transitioning to mobile development.

Pros: Large community, lots of libraries, JavaScript knowledge transfers easily.
Cons: Still relies on JavaScript bridge (performance hit), can feel "less native" than some alternatives.

Suitable industries/use cases: Ideal for social networking apps, e-commerce (especially with existing React/JavaScript teams), content-heavy apps, and MVPs (Minimum Viable Products) where speed of development is crucial.

Example: Building a social media app where you want to quickly launch on both iOS and Android, leveraging JavaScript skills for rapid iteration and access to social media APIs. Great for apps where native animations and complex gesture-based interactions aren't the primary focus. Also useable in Retail (Walmart) 

Our experience: A great example of our expertise is the Kalmar PDT - Perfect Delivery Tool. We developed this app to streamline Kalmar's commissioning process, replacing manual data entry and paperwork with a digital workflow. By utilizing React Native's native modules and extensive library ecosystem, we delivered an app that performs exceptionally across platforms while offering a near-native user experience.The application also has an offline mode so that users can use the application in places where there is no network. 

Popular apps built with React Native: Facebook, Instagram, Shopify, Microsoft Office apps
 

Flutter

Developed by Google, Flutter has seen tremendous growth and adaptation in recent years. It uses the Dart programming language and provides a rich set of pre-designed, customizable widgets that help create visually appealing interfaces.

Pros: Excellent performance, beautiful UI, "hot reload" is a game-changer.
Cons: Dart language (steeper learning curve), larger app size.

Suitable industries/use cases: Best for visually-driven apps, complex UI implementations, branding-focused apps, and situations where consistent UI across platforms is paramount. Examples include e-commerce apps with rich product displays, design tools, and creative apps. Also good for gaming apps

Example: Building a banking app where a polished UI and seamless user experience are critical for building trust and brand image. Flutter's widget system allows for highly customized and visually appealing UI elements.

Our experience: For a hospitality client, we built a management system that helped restaurants digitize their inventory management, create detailed nutritional information, and comply with food regulations. Flutter's performance capabilities were crucial for handling complex data visualizations and ensuring a responsive interface even when processing thousands of inventory items.This solution has proven instrumental in their food waste mitigation efforts through deep analytical metrics.

Popular apps built with Flutter: Google Pay, BMW, eBay, Alibaba

NET MAUI (formerly Xamarin) 

Microsoft's .NET Multi-platform App UI (.NET MAUI) is the evolution of Xamarin. Forms and enables developers to create native apps for Android, iOS, macOS, and Windows using C# and XAML.

Pros: C# and .NET familiarity, native UI components, good for enterprise apps.
Cons: Can feel a bit "enterprisey", larger app size.

Suitable industries/use cases: Ideal for enterprise applications, internal business tools, and scenarios where a .NET development team wants to extend its skillset to mobile. Best for data-driven apps and those that need to integrate tightly with existing .NET systems.

Example: Developing a CRM (Customer Relationship Management) system for internal use within a company that already relies heavily on .NET infrastructure.

Popular apps built with MAUI: Fareboom, The World Bank, Alaska Airlines, UPS
 

Ionic

Ionic is a framework for building hybrid mobile apps using web technologies like HTML, CSS, and JavaScript. It works with popular web frameworks such as Angular, React, and Vue. 

Pros: Easy for web developers, huge community, quick prototyping.
Cons: Relies heavily on WebViews (performance issues), doesn't feel truly native.

Suitable industries/use cases: Best for simpler apps, prototypes, and situations where web developers need to quickly deploy a mobile version of a web application.

Example: Building a simple event registration app that's primarily content-driven and doesn't require complex native functionalities.

Popular apps built with Ionic: MarketWatch, Sworkit, McDonald's apps
 

Kotlin Multiplatform (KMP)

The new kid on the block, but seriously promising. Kotlin Multiplatform (KMP) is gaining traction as a cross-platform solution that allows sharing code between Android, iOS, web, and desktop applications while maintaining native UI elements.

Pros: Share business logic across platforms, interoperable with native code, growing ecosystem.
Cons: Still relatively new, limited library support.

Suitable industries/use cases: Well-suited for apps where core business logic (e.g., data processing, authentication) needs to be shared across platforms while maintaining native UI for optimal user experience.

Example: Building a financial app where complex calculations and data validation need to be consistent across both iOS and Android, while still offering a fully native user interface.

Popular apps built with KMP: Netflix, Cash App, Philips

Alright, you've seen the options -  a whole toolbox of cross-platform frameworks. But for most projects today, two names consistently rise to the top: React Native and Flutter.

These frameworks are very reliable in the industry for what they provide.

React Native is suitable for rapid prototyping and apps that need to go to market quickly, using JavaScript. It can also provide an easy option to launch to test your product

Flutter is suitable for projects that need high performance and consistent native looks across platforms, and is ideal for interactive applications and those with complex visual requirements.

However, we cannot discount all those other options, those are also viable.

.NET MAUI is always great if you're already using that and you can create the best for that environment.

For Kotlin and IONIC is great, but just remember, that those skills sets can be more difficult to find

Choosing a cross-platform framework isn't just about picking the "most popular" one.
 

Each framework has its unique strengths and advantages, catering to different project requirements and developer preferences.

Your choice should be based on the unique requirements of your project and your specific needs for native integration and design preferences.

Here's a breakdown of factors we consider:

• The complexity of your app: Is it a simple content app? Or something that needs serious horsepower, and access to every native feature? The more complex your app, the more likely you are to hit the limitations of cross-platform frameworks.
• UI/UX requirements: How important is it that your app feels exactly like a native app? If it's critical, Flutter or MAUI are probably better choices. If you're okay with a bit of compromise, React Native or Ionic could work.
• Long-term maintainability: Consider the long-term health of the framework. Is it actively maintained? Does it have a strong community? You don't want to build your app on something that's going to be abandoned in a year.

Still feeling unsure? Our experts can help you make the call. Get in touch to discuss your needs.

Let's talk budgets, because that's often the deciding factor.

A common mistake is comparing only the initial development costs. The reality is more nuanced:

• Development costs: Cross-platform typically saves 30-40% compared to building separate native apps
• Maintenance costs: A single codebase is significantly cheaper to maintain
• Update costs: Feature additions and changes are applied once instead of twice
• Quality assurance costs: Testing needs are reduced, though not eliminated

But the most important cost consideration isn't technical at all - it's the cost of building the wrong thing.

Far too often, we see clients spend their entire budget on features users don't actually want. We'd rather help you build three iterations of a focused product than one bloated version with untested assumptions.

If you have a €100K budget, traditional agencies will break down your requirements, see how many they can squeeze in, and deliver a single "final" product. We advocate for a different approach:

1. Allocate €30K to build and validate your core hypothesis.
2. Apply the learnings from user feedback and iterate with another €30K cycle.
3. Refine further with a final €30K iteration.
4. Reserve €10K for launch and initial support.

This iterative approach dramatically reduces the risk of market failure while ensuring your investment delivers real value. More about our MVP approach can be read here.

So, is cross-platform app development the holy grail? Like most strategic decisions in software, the answer isn't black and white. After guiding dozens of clients through this exact question, we've developed a nuanced perspective:

For startups with limited resources and straightforward app requirements, cross-platform development offers compelling advantages. But don't fall into the trap of assuming it automatically translates to cost and time savings. Do your homework and understand exactly what you're getting into.

The choice between native and cross-platform largely depends on your specific needs:

Choose native development when:

• Your app requires intensive graphics or complex animations
• You need deep integration with platform-specific features
• Performance is absolutely critical to your app's success
• You have separate teams specialized in iOS and Android development

Choose cross-platform development when:

• You need to launch on multiple platforms quickly
• Your budget constraints require efficient resource allocation
• Your app has relatively standard UI requirements
• You need to maintain feature parity across platforms

When performance demands are high and UI complexity increases, native development often remains the better choice. The additional investment often translates to a superior user experience.

If your organization has strong expertise in a particular cross-platform framework, leveraging that existing knowledge typically outweighs switching approaches.

For highly specialized niche markets, focusing on a single platform with exceptional execution might yield better results than spreading resources thinly across multiple platforms.

The most crucial aspect of cross-platform mobile app development isn't the technology itself – it's the value it delivers.

Your users don't care about the framework you used. They care about whether your app solves their problems reliably and efficiently.

That's why we prioritize understanding your specific challenges before recommending a technology. Cross-platform is sometimes the right answer, and sometimes it isn't. The key is asking the right questions.

So, revisiting the core question:

Will cross-platform ever fully replace native Android development? Unlikely.

The subtle UX differences between iOS and Android remain. Even with advanced tools, compromises are often necessary.

The best approach?

It's not about picking sides in a tech war. It's about really, really understanding your business, your users, and your team's strengths. Make a smart decision based on those things, not just on what's trendy or on oversimplified comparisons.

Whatever you choose, go in with your eyes wide open - knowing there will always be some trade-offs. And remember, the people building the app and the strategy guiding them are way more important than the technology itself.

At ZenDev, we've seen firsthand how the right cross-platform approach can help businesses reach their users more efficiently, with less overhead and faster time-to-market. The frameworks continue to evolve rapidly, narrowing the performance gap with native development while improving developer experience.

Whether you're a startup looking to launch an MVP or an enterprise seeking to modernize your mobile strategy, cross-platform development deserves serious consideration in your technology planning.
