Cross-platform or native: how to choose for your app

Summary: For most business apps, start cross-platform with one codebase (React Native or Flutter); choose separate native apps only for heavy media, demanding offline sync, deep hardware access or very high performance needs.

The default for most businesses

React Native lets one team ship iOS and Android from one codebase. For booking, ordering, loyalty and content apps it delivers native-quality results for less money.

When native is worth it

Heavy video, complex animation, demanding offline sync or deep hardware access can justify separate Swift and Kotlin apps. These are the exceptions, not the rule.

Think about the next five years

Consider who will maintain the app, how often it will change and how easy it will be to hire for the stack. Running cost matters more than build cost over time.

A sensible path

Start cross-platform, measure performance with real users and move individual screens to native only if the data says so.

The options in plain terms

There are three realistic routes for a business app today.

• Cross-platform (React Native, Flutter): one codebase for iOS and Android, near-native results, one team. The default for booking, ordering, loyalty, content and internal apps.
• Native (Swift for iOS, Kotlin for Android): two codebases, the best performance and immediate access to new platform features.
• Progressive web app: a mobile website that installs to the home screen. The cheapest route, with limits on notifications and device features, especially on iOS.

A quick decision test

If most of these are true, cross-platform is the right start:

• The app mostly shows data and collects input (bookings, orders, profiles).
• You need both iOS and Android at launch.
• The same small team will maintain it.
• Animations and media are standard, not the core of the product.

Running costs matter more than build cost

Every app needs updating for new iOS and Android releases each year, plus fixes, store compliance and dependency updates. One codebase roughly halves that ongoing work, which over five years usually matters more than any difference in build cost.

Key takeaways

• Cross-platform is the right default for most business apps.
• Go native for heavy media, offline sync or deep hardware use.
• Budget for yearly OS updates whichever route you choose.
• A mobile website may be enough if people use you rarely.
