App Development: One Codebase, Two Platforms, Full Control
A dedicated app is not an end in itself, it is an investment that has to pay off. We build mobile apps with React Native as our default approach, because it delivers the best balance of speed, cost and quality in most projects. Where Flutter, native development or a Progressive Web App are the better choice, we say so just as openly.
Building an app is no longer black magic from a technical standpoint, the real challenge lies in deciding which path actually gets you there. A native app for iOS, a native app for Android, a cross-platform solution, or maybe just a Progressive Web App: each option has real trade-offs, and the wrong choice costs not only money but time you cannot win back in a competitive market. At mironsoft, we develop apps primarily with React Native, because this approach delivers the best result in the large majority of projects.
That does not mean React Native is always the answer. In this overview, we explain how we assess projects, when Flutter or true native development is the better choice, and why a PWA can sometimes replace the app entirely. It ends with an honest, direct comparison you can use to judge where your project belongs.
01
Why We Build Apps, and Why Usually With React Native
For many businesses, an app is the most direct channel to the customer: no algorithm in between, no ad auction, just an icon on the home screen. Whether it is an ordering app for an existing online shop, a customer portal, an internal operations app or a community product, the requirement is almost always the same: it has to work equally well on iOS and Android, look good, and stay within a realistic budget.
This is exactly where our default approach comes in. With React Native, we write most of the application logic once and ship two genuinely native apps from it, not a disguised website, but compiled, native code with access to camera, push notifications, Bluetooth, sensors and everything a user expects from a "real" app. That noticeably lowers development time and cost without users feeling any compromise in quality or usability. For most business apps, this is the economically smartest path, which is why it is our starting point, not our dogma.

Native vs. Cross-Platform: The Fundamental Decision Every Project Needs First
Before any conversation about frameworks, design or features, every app project starts with a strategic fork in the road: native development for each platform separately, or a cross-platform solution that brings one codebase to both platforms. This decision shapes budget, timeline and maintenance effort for the entire lifetime of the app, and it is expensive to reverse later.
Native development means one team writes Swift for iOS, a second team writes Kotlin for Android. Two codebases, two test cycles, two release processes. The upside is maximum performance and unrestricted access to every platform quirk, the price is roughly double the development time and permanently higher maintenance effort, because every change has to be implemented twice.
Cross-platform frameworks like React Native or Flutter solve exactly this problem: one codebase that compiles into native apps on both operating systems. For the vast majority of use cases, from shopping apps to customer portals to internal operations apps, the advantages here clearly outweigh the downsides. Only for very specific requirements, such as extremely performance-critical games or apps that reach deep into proprietary hardware interfaces, does the native overhead genuinely pay off. We address this assessment openly in every initial conversation, before a single line of code is written.
03
Our Three Approaches at a Glance
Depending on the project's requirements, we rely on one of three paths, and only recommend it when it genuinely fits.
A. React Native – Our Default Approach
JavaScript or TypeScript, a huge library landscape, and a bridge to native components that feel like the real thing. React Native is used in production by Meta itself (in the Facebook and Instagram apps, among others) and benefits from one of the largest developer ecosystems anywhere. Our first choice for most business apps.
B. Flutter – The Alternative for Consistent Design
Google's framework renders the entire user interface itself instead of using native components. The result is pixel-perfect and identical on every device, a real advantage for brand-heavy, design-intensive apps. The language behind it, Dart, is less widespread than JavaScript, but very performant.
C. Native iOS + Android – For Special Cases
Swift for iOS, Kotlin for Android, each developed directly on the platform. Maximum performance, unrestricted access to every operating system API, but also the highest effort. Sensible for apps with extreme performance requirements or very deep hardware integrations.
04
Why React Native Is Usually the Right Choice
React Native is not a compromise, in most cases it is the economically and technically superior solution. It is built on React, one of the most widely used frontend technologies in existence, which opens up a huge talent pool and a mature ecosystem of libraries. What does that mean concretely for your project?
One codebase, two apps: Up to 90% of the code is shared between iOS and Android, so features only need to be built and tested once.
Genuinely native handling: React Native renders native UI components, not simulated ones. Scrolling, transitions and gestures feel like any other native app.
Faster time to launch: Shorter development time means your app reaches the store sooner and starts generating revenue or customer value earlier.
Huge ecosystem: For almost any requirement, from payment providers to map integrations to push services, a mature library already exists.

Figures That Speak for Cross-Platform Development
App development is an investment decision, not a purely technical question. Industry data and our own project experience show where cross-platform approaches make an economic difference.
-35%
Development cost: A shared codebase for iOS and Android typically saves a third to over half the budget compared to two parallel native teams.
~90%
Shared code: In a typical React Native app, the large majority of the logic is reused across both platforms, only a few spots need platform-specific code.
1 Team
Instead of two: One development team can cover both platforms, instead of coordinating and paying for two separate specialist teams.
These figures are not a guarantee, they are experience-based benchmarks that vary by project scope. But the direction is clear: for most apps with a classic business use case, cross-platform development with React Native is the more economical path, without users getting a lesser app.
06
The Honest Comparison: React Native vs. Flutter vs. Native Development vs. Progressive Web App
No approach is always right, which is why we lay the decision out openly. React Native is our default because it offers the best balance of cost, speed and user experience for most business apps. Flutter is a strong alternative when a pixel-perfect, brand-heavy design needs to look identical on every device. Native development remains the right choice when maximum performance or deep hardware integration is the priority. And a Progressive Web App can sometimes even be the better solution, particularly when no app store listing is required and budget is the main concern.
The table below summarizes the key differences the way we explain them to our clients in the initial conversation, without marketing exaggeration in either direction.

Frequently Asked Questions (FAQ) About App Development
Why does mironsoft use React Native as the default?
Because it offers the best balance of development time, cost and user experience for most business apps. One codebase serves iOS and Android at the same time, while the app remains genuinely native, not a disguised website. For projects with special requirements, such as very design-intensive apps or games, we evaluate Flutter or native development as alternatives.
What does it cost to develop an app?
That depends heavily on the feature scope: a lean app with a handful of core functions differs significantly in price from an app with its own backend, payment processing and complex user management. After a short initial conversation, we can give you a realistic range that fits your specific project.
How long does it take to develop an app?
A lean version with core functions (MVP) is often achievable with React Native in 8 to 12 weeks. More extensive apps with their own backend, several user roles and complex integrations require correspondingly more time. Duplicate native development for iOS and Android usually takes considerably longer, because every function has to be built twice.
When should I choose Flutter instead of React Native?
Flutter pays off mainly when a pixel-perfect, identical design across every device matters more than platform-typical behavior, for example with strongly brand-driven apps with many custom animations. Flutter can also have the edge for certain performance-critical UI requirements. We walk through this decision in the initial conversation based on your specific requirements.
Wouldn't a Progressive Web App be enough instead of a real app?
Sometimes, yes. A PWA is cheaper, needs no store listing, and can be updated faster. But it hits limits as soon as deeper hardware integration, offline capability or fully reliable push notifications are required, and it rarely feels like a "real" app once it sits on the home screen. We honestly assess whether a PWA is sufficient for your use case before recommending a native app.
Does mironsoft also handle publishing on the App Store and Play Store?
Yes. We handle the complete submission including the store listing, screenshots, description texts, and alignment with Apple's and Google's guidelines. Especially on the first submission there are a number of formal pitfalls we know from experience and avoid from the outset.
How does maintenance work after launch?
Operating systems, libraries and store guidelines keep evolving, so every app needs ongoing care. We offer maintenance packages that cover OS updates, security patches and minor adjustments, keeping your app stable and store-compliant over time.
Can an existing website or online shop serve as the basis for the app?
In many cases, yes. If an API or a shop system like Magento already exists, the app can build on it and reuse the same data for products, orders or customer accounts instead of maintaining everything twice. That noticeably reduces effort and error rates.
What is the difference between an app and a responsive website?
A responsive website runs in the browser and adapts to any screen size, an app gets installed, sits as an icon on the home screen, and can send push notifications, work offline and interact deeply with the device. When repeat usage, customer retention and device access are the priority, an app is usually the stronger choice.
