React Native (Cross-platform mobile framework)

Updated: July 9, 2026

At a glance

Learning curve

Easy for React developers; the real curve is native tooling (Xcode, Gradle) and writing native modules when you hit the edges.

Performance

Near-native for most business apps since the New Architecture (Fabric and JSI); graphics-heavy screens still need careful optimization.

Ecosystem

Huge JavaScript ecosystem behind it, and Expo makes builds, publishing and over-the-air updates remarkably simple.

Ideal for

• Startups shipping iOS and Android from one codebase
• Teams that already have React web code and skills
• Apps dominated by business UI (forms, lists, feeds)
• Products that benefit from over-the-air updates

Pros

• One codebase for iOS and Android with real native components
• Skills and code shared with React web teams
• Expo delivers a best-in-class developer experience
• Over-the-air updates skip app store review for JS changes
• Very large community and third-party module catalog

Cons

• Edge cases still require writing native modules in Swift or Kotlin
• Version upgrades have historically been painful
• Performance ceiling below fully native for graphics-intensive apps
