What is cross-platform app development?
In cross-platform development an app is written once, in one code base, and runs on several operating systems, usually iOS and Android, and often the web and desktop too. Flutter and React Native are the usual frameworks.
Also called: cross-platform app
Why it matters
One code base means one team, one feature list and one bug list for both stores, so you launch on iPhone and Android at the same time for less. The cost shows at the edges: unusual device features may still need some native code.
1Shared codeScreens and business logic are written once; only small platform-specific parts differ.
2Unlike a PWACross-platform apps are real store apps with device access; a PWA is a website installed from the browser.
3Cross-play in gamesIn gaming, cross-platform play means players on different consoles and PCs share one match, a separate topic.
ExampleA water delivery service in Shymkent needs an app for customers and couriers on both iPhone and Android. Built cross-platform in Flutter, both versions come from one code base and reach the stores together. Live GPS tracking of couriers in the background uses a small native module on each side.
