Cross-platform development with Flutter or React Native covers most business tasks: one codebase runs on iOS and Android, and both the launch and the upkeep cost less. Native development is needed where an app leans on the device itself: heavy graphics, background sensor work, rare system features. The feature list and the maintenance budget decide the answer, not framework fashion.
Native development means two separate programs: one in Kotlin for Android, another in Swift for iOS. Each one calls system interfaces directly, with no layer in between.
Cross-platform development means a single codebase that builds apps for both platforms. Flutter is written in Dart, React Native in JavaScript or TypeScript, and Kotlin Multiplatform splits a project into shared logic and a native interface.
The difference is not in the quality of the result but in where the border between shared and platform code runs. The more features depend on a specific device, the closer that border sits to native development. We described the stages a project goes through in our article on building apps for iOS and Android.
The «which one is better» debate is useless without a feature list. Compare the approaches on the parameters that end up in the quote and in the maintenance schedule, not on abstract performance.
| Criterion | Native development | Cross-platform development |
|---|---|---|
| Codebase | Two: Kotlin for Android, Swift for iOS | One shared base plus a thin platform layer |
| Time to reach both platforms | Longer: every feature is built twice | Shorter: one implementation covers both platforms |
| Access to device features | Direct, any system interface | Through ready-made plugins or your own native module |
| Interface | Fully aligned with the platform rules | One design, platform details are tuned separately |
| Team | Two developer profiles and two sets of tests | One developer profile for both platforms |
| Reaction to new iOS and Android versions | As soon as the system developer kits ship | Once the framework supports the update |
| Support after launch | Two branches of fixes, double regression testing | One fix ships to both platforms at once |
| Main risk | Budget and timeline | Dependence on the framework and third-party plugins |
Native code pays off where an app spends most of its time working with the phone hardware rather than with screens and data.
In these scenarios a cross-platform framework still has to be extended with native modules for both systems, and the savings disappear.
The cross-platform approach wins when the app is essentially an interface to your data and processes.
Count the maintenance separately. An app lives for years, and every fix in a native project is made twice: the Android developer and the iOS developer repeat the same work.
The three tools solve different problems, and the choice depends on how much you are ready to move into shared code.
Flutter draws the interface with its own engine, so the app looks the same on every device. Since version 3.27 the Impeller engine is enabled by default on iOS and on Android from API 29, as the Flutter documentation states. It fits when a single branded interface and predictable animation matter most.
React Native builds the interface from system components, so the screens feel closer to what the platform users expect. In version 0.76 the New Architecture became the default, as the React Native team announced. It fits companies that already run a JavaScript web team and share logic with the site.
Kotlin Multiplatform is the middle ground: calculations, networking and data storage are shared, while the interface stays native on each platform. Google officially supports this way of sharing business logic between Android and iOS. It fits larger products where the interface must feel native and the business rules must stay identical.
One more criterion is who will maintain the code a year from now. An app outlives several developers, so pick a tool you can realistically hire for, not the one the current team enjoys. The check is simple: look at recent job postings and CVs for each framework in your city.
The promise of «one codebase for two platforms» holds for screens and business logic, but not for system features. As soon as the app needs an interface that no ready plugin covers, a developer writes a platform channel: Kotlin code for Android and Swift code for iOS. The Flutter documentation describes this mechanism as the standard way to reach system capabilities.
The practical conclusion: do not count the share of common code, count the features that have no plugin. Usually these are payment libraries of local providers, corporate device management systems and specific hardware such as scales, receipt printers and scanners.
That is why it pays to list every external integration at the start of the project and check whether each one has a maintained plugin. A single integration without a plugin means two native implementations plus a person who can write them.
First, the device mix. According to Statcounter data for August 2026, Android holds 83.14 % of mobile devices in Uzbekistan and iOS holds 16.85 %. For many products that means both platforms do not have to launch together: you can ship on Android, collect feedback and add iOS as a second step.
Second, payments. For card payments inside an app, Payme offers an Android SDK with a ready-made interface, which is a native library. In a cross-platform project it is wired in through a platform module, and that work has to be in the estimate from the start.
Third, Telegram. Part of what businesses order an app for is covered faster and cheaper elsewhere: booking, orders and notifications run in a customer account inside Telegram, with no store install and no yearly fees. Compare both options before you approve an app budget.
Fourth, the interface language. An app for the local market usually needs Uzbek and Russian, often English too, switchable right in the settings. In a shared codebase the strings are translated once; in a native project they are handled separately for Android and iOS, and the drift between versions has to be caught by hand.
Development is only the first payment. After that the app lives by store rules, and those costs are the same for either approach.
At Syntra Systems we start with the task, not with the framework. The order of steps is this.
If the features touch the device rarely and both platforms are needed at once, we build a cross-platform app and keep native only the places that cannot work otherwise. If the app lives on the phone hardware, we build it natively instead of stretching the budget on intermediate layers.
From there we work as one team: interface, backend, integrations with CRM and payment systems, publishing to both stores and support after launch. You can discuss your task and get an estimate on the page for websites and platforms development.
Yes, and it is a common path: a product starts on Flutter or React Native, and a native version appears when load or new features demand it. You rewrite the interface and the device-facing code, while the backend, the data and the store accounts stay as they are.
In a typical business app built from lists, forms and notifications the difference is rarely noticed. It shows up in complex animation, during long camera sessions, and at the moment the system gains a new capability that the framework does not support yet.
Yes, the framework itself does not affect the review. Rejections usually come from the content: the app repeats a website without adding value, breaks the payment rules, or fails to explain why it asks for the permissions it requests.
Not necessarily. If your audience is mostly on Android, it is reasonable to ship one platform, collect feedback and add the second once the feature set has settled. On a cross-platform project the second launch costs noticeably less.
Almost always yes: the catalogue, orders, profiles and notifications live on a server, and the app only displays the data. If the business already runs a website or a CRM, an API is usually added to them rather than a second system built from scratch.
A bot launches faster and needs no install, no store review and no yearly fees, so it is usually cheaper for testing demand. An app is justified when you need offline mode, work with the device, or your own notification channel.
Ask them to justify the choice with the feature list: which features touch the device, which ones have ready plugins, and what has to be written natively. An answer like «we always use this framework» means the task was never analysed.
