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 be aware of 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 way to achieve 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 access to 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 especially when an app should look and behave 100% like a genuine Android or iOS app, when deliberately different features for the two operating systems are planned, orwhen an existing team already has native codebase and Swift or Kotlin expertise.A technical special case remains 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, however, 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 exactly wherea closer look at costs and effort is worthwhile, 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 usually 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 one's 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 across-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, as often implemented by LEAN-CODERS, native app costs typically range between 70,000 and 150,000 euros becauseboth platforms are developed separately.A comparable cross-platform solution with a shared codebase is often significantly lower, as already 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 is proficient in both Swift and Kotlin. This not only increases the one-time development costs but also the ongoing costs over the entire lifecycle of the app.

Not to mention typical effects that we experience repeatedly in everyday life, where the Android and iOS app versions slowly and steadily drift apart over the medium term, leading to confusion among users as well as their own support staff, as features, structure, functions, and sometimes even small decisions increasingly diverge.

A look at the budget distribution showswhy this difference is so significant.Frontend development accounts for 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 result from it. This is precisely the lever 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 quickly reach the market or internal users, this is a real disadvantage.

• Larger team required.Native development requires specialists for iOS and Android separately. This makes teams larger, projects more complex in coordination, and increases dependence 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 dependence 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 because 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 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 individual cases depends on the team, project requirements, and planned maintenance strategy.

Which of the two frameworks is the better choice in individual cases 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 sufficiently 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 concrete 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 in 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, it is essentially possible to implement everything that native applications can do, even complex games run performantly and look convincing.

Connecting to wearables, third-party devices, or home widgetsis now easily possible through these frameworks..

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

Native App vs. Web App vs. Hybrid App: How do you 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 web apps and native development, but depending on implementation, it brings 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,because it combines native performance with a shared codebase.

A simple rule of thumb helps with orientation: If a presence in the browser is sufficient, aweb 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 additional effort of a 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.
