"Native" means building the iOS app and the Android app separately, each with the tools Apple and Google provide. "Cross-platform" means writing most of the app once and running it on both. Either way you ship real apps to the stores. The approaches differ in cost, flexibility and long-term upkeep.
Native
iOS in Swift (often with SwiftUI), Android in Kotlin (often with Jetpack Compose). Two codebases, each using the platform's own interface components.
Cross-platform
Frameworks such as Flutter (Dart) and React Native (JavaScript or TypeScript) share most code across iOS and Android. Kotlin Multiplatform shares business logic while keeping native screens.
Native vs cross-platform trade-offs compared
| Question | Native | Cross-platform |
|---|---|---|
| Build effort for both platforms | Higher: two codebases | Lower: most code shared, though some platform-specific work remains |
| New OS features on release day | Available directly | Sometimes need a plugin or custom native code first |
| Performance for typical business apps | Very good | Usually good enough; heavy graphics or animation may favor native |
| Deep hardware use (Bluetooth devices, background tasks, AR) | Most direct | Possible, often through native modules |
| Look and feel | Platform-standard by default | Can match each platform or use one shared design |
| Long-term upkeep | Two codebases to update | One main codebase plus framework upgrades and plugin updates |
| Hiring later | Separate iOS and Android skills | Depends on the framework's popularity where you hire |
When native app development is worth it
- The app depends on hardware or OS features such as Bluetooth accessories, background location, widgets, watch apps or advanced camera work.
- You only need one platform, for example an internal app on company-issued iPhones.
- Smooth, complex animation or graphics are central to the product.
When a cross-platform app makes sense
- You need iOS and Android at launch on a limited budget.
- The app is mostly forms, lists, accounts, payments and notifications, which describes many business apps.
- You want one team and one release schedule for both platforms.
Is a progressive web app enough?
A progressive web app runs in the browser and can be added to the home screen. It skips app store review, and one codebase serves every device. It has real limits: support for some features differs between browsers and platforms, especially on iOS, and people won't find you in the stores. For internal tools and simple customer portals it's worth considering first.
Questions to ask an app developer about the approach
- Why do you recommend this approach for my app in particular?
- Which features will need platform-specific code, and how much of the budget goes on that?
- Which third-party plugins does it depend on, and how well maintained are they?
- If we change developers later, how easy will this codebase be to hand over?
Whichever route you take, the framework and plugin updates become part of your ongoing maintenance, and a handover only works if the code and accounts are in your name.
Native and cross-platform questions
Is Flutter or React Native the better choice?
Both are used to ship business apps on iOS and Android. The better fit depends on the features you need, the plugins available for them, and who will maintain the code. Ask the developer to explain the choice for your app specifically.
Can a cross-platform app be rebuilt as native later?
It can, but it usually means rewriting the app's code for each platform. A backend and APIs built separately from the app can often stay as they are.
Does cross-platform always cost less?
Building for both platforms usually takes less effort with shared code, though some platform-specific work remains. If you only need one platform, native may cost about the same or less.
