Native App Development: Costs, Disadvantages, and Alternatives for Your Business

For a long time, native app development was seen as the only way to achieve great performance and access all device features, even though the same performance and capabilities are now available for 95% of use cases. Anyone needing an app for iOS and Android should know the actual costs, practical disadvantages, and available alternatives before making a decision. This article shows when native development is truly worthwhile, what it costs, and what options B2B companies realistically have today.

What does native app development mean and when is it sensible?

Native app development means programming an app separately for iOS with Swift (formerly Objective-C) and for Android with Kotlin/Java. Each platform gets a completely independent codebase, tailored to the respective operating system standards.Native app development means programming an app separately for iOS with Swift (formerly Objective-C) and for Android with Kotlin/Java. Each platform gets a completely independent codebase, tailored to the respective operating system standards.

For a long time, native development was considered the only path to maximum performance and full access to device features. Modern cross-platform frameworks like Flutter have significantly narrowed this gap in recent years. Flutter apps achieve performance in most cases that is hardly distinguishable from native apps, and accessing native device features or existing Swift and Kotlin libraries is now easily possible through mechanisms like Method Channels, Platform Views, or FFI.

Native development remains the right choice primarily when an app needs to look and behave 100% like a genuine Android or iOS app, when deliberately different features for the two operating systems are planned, or when an existing team already has native codebase and Swift or Kotlin expertise. A technical special case arises when native SDKs embed their own visual elements directly into a Flutter app, which can lead to slight performance losses with very complex content. However, for the vast majority of B2B use cases, this is practically irrelevant.

For most B2B applications, these scenarios are actually rarer than one might initially assume. Internal tools, customer portals, or business apps with forms, dashboards, and API connections rarely require a 100% platform-specific look-and-feel or functions that can only be implemented natively. This is precisely where it pays off to take a closer look at costs and effort, before deciding on the native route. A hospital system for evaluating medical sensor data in real-time can benefit from native development. An internal portal for proposal approval typically does not need it.

The decision for or against native development can be made based on three questions: How important is a 100% platform-specific appearance? Should deliberately different functions exist for iOS and Android? And does the existing team already have native expertise and codebase? Answering these three questions for your own project usually provides a clear tendency before even obtaining a quote.

What does native app development cost compared to alternatives?

The costs of native apps are significantly higher than those of a cross-platform solution, because practically two completely separate projects are created, one for iOS and one for Android. Each function must be designed, developed, tested, and maintained twice.

For a B2B project of medium complexity, which LEAN-CODERS frequently implements, native app costs often range between 70,000 and 150,000 euros, because both platforms are developed separately. A comparable cross-platform solution with a shared codebase is often significantly lower, as shown in the article on app development costs. The difference also reflects in maintenance. Two codebases mean double update cycles, double bug fixes, and a team that must be proficient in both Swift and Kotlin. This not only increases the one-time development costs but also the ongoing costs over the entire lifespan of the app.

Not to mention typical effects we experience in everyday life, where the Android and iOS app versions gradually diverge over the medium term, leading to confusion among users and even among support staff, as features, structure, functions, and sometimes even small decisions increasingly differ.

A look at the budget distribution shows why this difference is so significant. Frontend development constitutes the largest cost block in most app projects, often around 28 percent of the total budget. In native development, this block is practically doubled because frontend code for iOS and Android is written completely separately. Backend, testing, and project management can often be shared, regardless of whether one, two, or three codebases are created. This is precisely the leverage that cross-platform approaches exploit.

What disadvantages does native app development have for B2B companies?

In addition to costs, native app development brings further disadvantages that often weigh more heavily for B2B companies than the pure price.

• Longer time-to-market. Because both platforms are developed in parallel or sequentially, a native project usually takes noticeably longer than a cross-platform project with comparable functionality. For companies that want to reach the market or internal users quickly, this is a real disadvantage.

• Larger team required. Native development requires specialists for iOS and Android separately. This makes teams larger, projects more complex to coordinate, and increases dependency on individual specialists.

• Higher maintenance effort. Every feature, every bug fix, and every update must be implemented twice. Over several years, this adds up to a significant additional effort compared to a shared codebase.

• Higher dependency on individuals. If an iOS specialist or an Android specialist leaves the project, a gap arises that cannot simply be filled by other team members, as the two platforms use different languages, tools, and conventions. With a shared codebase, this risk is significantly lower.

These disadvantages do not mean that native development is fundamentally the wrong choice. However, they show why taking a closer look at alternatives is worthwhile for most B2B projects before making a fundamental decision.

What alternatives to native app development are there?

Cross-platform frameworks. The most obvious alternative is cross-platform frameworks like Flutter or React Native. Both allow for a shared codebase for iOS and Android, significantly reducing development time and costs without sacrificing noticeable quality in most B2B use cases. Which of the two frameworks is the better choice in a specific case depends on the team, project requirements, and planned maintenance strategy.

Flutter is backed by Google, the same company that develops Android itself, a fact that ensures the framework has deep technical resources, long-term development, and reliability as a cross-platform standard. Which of the two frameworks is the better choice in a specific case depends on the team, project requirements, and planned maintenance strategy.

How precisely Flutter can access native functions like geolocation is demonstrated in a conference talk by Simon Eckerstorfer.

• AI-supported development. A second, newer alternative is AI-supported app development. Tools based on AI models can now generate boilerplate code, simple UI components, and initial prototypes significantly faster than before. For very simple applications or early proofs of concept, this can save time and costs.

Complex backend connections, data protection requirements, and quality assurance over the entire lifecycle still require experienced developers who can assess, correct, and integrate AI results into a stable overall system. AI alone currently does not adequately cover these requirements, especially for production-ready B2B apps with high demands for security and long-term maintainability.

In practice, the most realistic approach often works as a combination: AI tools accelerate individual development steps like prototyping or test case generation, while experienced developers continue to be responsible for architecture, integrations, and quality assurance. This combination can significantly reduce time and costs without taking on the risks of a purely AI-generated production application. We will show how this approach looks in specific customer projects in a separate article on AI-supported app development at LEAN-CODERS.

Mostly unknown advantages of modern cross-platform frameworks

Existing code can be exported as a web app with relatively little effort, without making significant compromises in performance.

Modern frameworks can be embedded into existing native Swift or Kotlin codebases and vice versa, and communication with other SDKs and languages like JavaScript is also possible. Through access to Swift and Kotlin libraries, essentially anything that native applications can do can be implemented, even complex games run efficiently and look convincing.

Connecting to wearables, third-party devices, or home widgets is also easily possible with these frameworks today..

Technically, frameworks like Flutter fundamentally rely on the same building blocks as Swift and Kotlin, just from a shared base, an approach that Google has developed with its long-standing Android experience. We will cover how this works in detail in a separate, deeper article.

Native App vs. Web App vs. Hybrid App: How to Make the Right Choice?

In addition to native and cross-platform apps, there are two other categories that are often debated in practice: web apps and hybrid apps.

A web app runs directly in the browser and does not require installation via an app store. This makes it particularly inexpensive and quick to implement, but it lacks full offline capability and direct access to many device features.

A hybrid app combines web technologies with a native shell that can be published in the app store. It is usually priced between a web app and native development, but depending on the implementation, it may involve compromises in performance and user experience.

For most B2B companies that need a fully functional app with a good user experience on both platforms, a cross-platform solution is often the most obvious choice today, as it combines native performance with a shared codebase.

A simple rule of thumb helps with orientation: If a presence in the browser is sufficient,a web app is usually the fastest and cheapest option. If the app needs to be discoverable in the app store but without the highest performance requirements, a cross-platform or hybrid solution is usually sufficient. Only when deep hardware integration or maximum performance is a priority does the extra effort of fully native development justify itself.

Whether native development, cross-platform, or a combination of both is more sensible depends on your specific project. LEAN-CODERS helps you find the right solution for your company based on real requirements rather than standard answers.
