Cross-platform development is the default choice for most modern business apps. Here is what it means and why it is so popular.

What Is a Cross-Platform App?

A cross-platform app is built from a single codebase that runs on both iOS and Android, using frameworks like Flutter or React Native. One team writes the app once, and it compiles to near-native apps for both platforms — combining most of the quality of native with the cost savings of a shared codebase.

Why a Cross-Platform App Matters

Cross-platform development cuts cost and time dramatically: one codebase instead of two typically saves 30–40% versus building separate native apps, and you launch on both stores at the same time. For the majority of business apps, the performance is indistinguishable from native.

Example

A retail or booking app that needs to reach both iPhone and Android users quickly and affordably is an ideal candidate for Flutter or React Native.

Frequently Asked Questions

What frameworks are used for cross-platform apps?

The two leading frameworks are Flutter (by Google) and React Native (by Meta). Both let you build iOS and Android apps from one codebase.

Is a cross-platform app as good as native?

For most business apps, yes. Modern cross-platform frameworks deliver near-native performance; native still wins for the most demanding games, AR and hardware-heavy apps.

Is cross-platform cheaper than native?

Yes. A single shared codebase for iOS and Android typically saves 30–40% compared with building two separate native apps.
